Average humidity in uk house: Humidity In House Vs Outside – Tested

Humidity In House Vs Outside – Tested

This is a question we are often asked and, put simply, it depends on a lot of factors. That said, in the UK, for an ‘average’ home relative humidity tends to be in the 30% to 60% range. Most often it would be in the 40% to 50% range in most parts of the house.

We say ‘most parts of the house’ because, as we have seen in previous articles we have written this can vary a lot by room, especially in bathrooms, you can see more on this in our articles which explain:

Room Temperature and Humidity
Bathroom Condensation
Kitchen Extractor Fans
Condensation on Windows
Damp on Walls

In those articles, you can find useful information on what causes humidity in houses, which in turn can lead to condensation, damp, and eventually mould problems.

Humidity in Houses

Things Affecting Humidity in Houses

Here is a quick recap of the top things that can affect humidity in houses. We are going to split these into causes of humidity and things that can (or prevent in many cases) removal of humidity.

Let’s start with the top five things that add to humidity:

As you might expect, a water leak can increase humidity
Occupants of a house, directly – our bodies and breathing out moist air!
Occupants of a house, indirectly – cooking, bathing and laundry etc
Plants and animals can add moisture to the indoor environment
Environmental conditions outdoors and indoors (including heating)

More on that last point later but for now, to help balance out some of the things above, what can you do to help reduce humidity in your home?

Here are the top 5 things that can help control or reduce humidity:

Improving ‘natural’ ventilation – opening windows, vents etc.
Improving ‘mechanical’ ventilation – extractor fans or PIV units
Controlling moisture transfer – close the door when you have a bath!
Effective heating, including placement (warm air holds more moisture)
Keep an eye on moisture sources (including those listed previously)

Heating and Ventilation

On the subject of fans, heat and temperature, you may be interested in our article about if fans do help cool you in hot weather (and the cost to run them!)

Humidity in House vs Outside Conditions

Whenever you look into how to control humidity in houses, ventilation is often mentioned. This is because generally, by having good ventilation (natural or mechanical) you can either extract higher moisture containing air or introduce lower condensation air. Both of which have the affect of reducing indoor condensation.

But is outdoor air really lower in condensation than indoors? In order to look at this, we ran a test over a weekend in January 2022. We placed data logging humidity meters, which also tracked temperature, in four locations to compare, those locations were:

In the lounge of a property
In the conservatory of a property
In the garage of a property
Outside the property

As you can see, we chose these as each of them (a) varies and (b) moves each step from an indoor to an outdoor environment in increments. The results are below.

First of all, let’s look at the temperature inside vs outside (more on this later):

Temperature in House and Outside

As you can see, there was quite a difference between indoor room temperature in the lounge and outside, which is what you would expect in winter! Also as you would expect, the lounge was generally warmest and it got progressively cooler in the conservatory (about 5°C colder) and the garage (about 5°C colder again) and the outside, which was about 2-3°C colder than the garage.

Interestingly over the weekend it was generally rainy, which will have an effect.

So now, let’s look at the humidity levels in each area:

Humidity in House and Outside – graph

As you can see above, the numbers were ranked in the reverse order of temperature, with higher humidity outside. But wait, I can hear you say!…

If relative humidity is higher outside, why would I want to ventilate to let that air in when it is higher than indoors? So, there are two things to remember, which are related to each other.

We measured relative humidity in our silica gel packets test, which is worth reading..

Firstly, remember that relative humidity is – “the amount of water moisture / vapour in the air, expressed as a percentage, relative to what that air is capable of holding at a given temperature“. That last part is important as – as temperature rises, all other things remaining equal, relative humidity (not absolute humidity) falls as warmer air is capable of holding more moisture.

Because it was much colder outside (by more than 10°C) that colder air can hold less moisture, making relative humidity higher. However, if we look at actual moisture in the air (measured in Grams of Moisture Per Kilo of Air – GPK), outside was around 6 GPK vs 7 indoors, so less.

Plus, remember that when looking at places with much higher humidity than in a lounge, especially bathrooms, you see situations of temperature around 20°C and 90% relative humidity. In GPK terms that is around 15-16 which is much higher. Replacing or extracting moist air like that is beneficial to control humidity. The main downside would be that, if you are simply opening the window, colder air is coming in, which is why extractor fans and PIV units are beneficial.

Is higher or lower humidity better?

Whether higher or lower humidity is better will vary on a number of things. Firstly the context you are talking about, ideal humidity in houses may be different to outside, or for example, in industrial settings or farming (indoors or outoors). Plus, there is an element of personal preference, especially humidity in houses. That said, generally a mid-range humidity in houses is seen to be best, not to humid and not too dry. 40%-50% is a good middle range.

What Should The Humidity Be In A House? Know Your Levels!

Although your mind may drift to far-off shores and dense rain forests whenever humidity is mentioned, it’s an ever-present in our atmosphere. Despite being about as natural as things get, humidity in the home can pose problems – both at the high and the low end of the scale – which begs the question, What should humidity levels be in the home?

We’re going to find that out in today’s post, as we explore humidity’s impact on our lives and what causes it to rise and fall inside our properties.

Let’s get started, shall we?

What is humidity?

In the most basic terms, humidity is a measurement of how much water vapour is present in the air.

Humidity is vital to Earth’s ecosystem, as it forms an essential stage in the planet’s overall water cycle. Generated by evaporation and distributed by condensation, humidity naturally occurs as the liquid from water sources vaporises and enters the atmosphere.

Higher air temperatures are capable of holding more moisture than colder climes, hence the reason why we often think of tropical scenes whenever humidity is mentioned. However, with the advent of central heating and improved insulation, we are inadvertently creating our own microclimates indoors, and that can cause multiple issues to our health and the structure of the buildings we inhabit.

What’s the ideal humidity level in a UK home?

The range in which optimal indoor humidity is achieved is, thankfully, quite broad. If you’re getting a reading somewhere between 30 and 60%, you’re in pretty good shape. That being said, it can prove to be tricky to maintain such levels, so constant monitoring is a good idea. This can be done by way of a hygrometer, which can be purchased online for under a tenner.

As one would expect, the changing seasons mean changing humidity levels. The difference, though, is relatively slight. Both winter and summer levels fall within the 30-60% range, with a 10% variation at the appropriate end of the scale:

Optimal indoor summer humidity levels: 40-60%

Optimal indoor winter humidity levels: 30-50%

Very high readings are considered to be anything above 70% humidity, while low humidity is anything below 25%. These should be addressed regardless of the time of year.

What causes high humidity in the home?

As we’ve already discovered, humidity is essentially water vapour in the air. It stands to reason, then, that high humidity is an excess of water vapour that is basically trapped inside your home, but where does it come from?

Mostly, us!

Yep, we’re usually to blame. Just living our modern-day lives creates an enormous amount of moisture. For example, The Institute of Specialist Surveyors and Engineers state that everyday activities generate moisture at the following rates:

Sleeping: 40g of water per hour, through perspiration and exhalation

Doing housework: 90g of water per hour, through perspiration and exhalation

Cooking on a gas cooker: 3,000g per day

Cooking with an electric cooker: 2,000g per day

Using a dishwasher: 400g per day

Washing your clothes: 500g per day

Drying your clothes inside: 1,500g per day

As you can see, it doesn’t take much for humidity levels in the home to soar, and you need to find a way to get rid of it. Take a look at our guide to stopping condensation for some top tips to keep your indoor moisture levels in check.

It’s also worth pointing out that something altogether more sinister could be at the heart of your high humidity problem: a leaking pipe. Keeping an eye on your home’s humidity levels can be an early warning system for larger issues.

What causes low humidity in the home?

The other end of the humidity scale is usually a rarer occurrence, but it can happen. Common causes are excessive use of air conditioning systems and/or dehumidifiers, but it can also come about when we overheat our properties when the mercury drops outside.

Heating removes some of the air’s moisture and as the cold air from outdoors is already carrying very little water vapour, low indoor humidity can occur pretty quickly.

Three signs your indoor humidity levels are either too high or too low

As we’ve already mentioned, buying a hygrometer will take all of the guesswork out of things, but there are a few telltale signs that your indoor humidity levels may be suboptimal. These are:

Respiratory issues – If you’re having difficulty breathing or find that you often have a tight chest, humidity could be the root cause.

Poor sleep – Humidity levels that are either too high or too low will affect how you sleep. Dry air will irritate your throat, while high humidity will cause the body to work harder while you rest.

Poor body temperature regulation – If you’re always too hot or too cold, you may find that your indoor humidity levels need adjusting as much as your heating.

How to manage humidity all year round

The biggest tip is…ventilate. Circulating the air inside our properties is absolutely vital if you want to keep condensation at bay and maintain healthy humidity levels inside your home all year round, so throw open those windows. Yep, even in winter.

All that’s required is 10-15 minutes of fresh air from several open windows, so you get a ‘through-draft’, and you’re done. This will remove a lot of the trapped moisture and allow you to let other nasties, such as Volatile Organic Compounds (or VOCs, for short), to escape as well.

How to Reduce Humidity Levels Inside the Home [Updated 2022]

Humidity is a measurement of the water content in the air. It’s usually measured in percentages or grams per cubic metre.

If humidity levels are too low or too high, you may notice adverse health conditions and issues in the home such as damp patches or wooden floor panels shrinking.

The humidity inside a typical home will vary throughout the year for varying reasons, including air temperature and ventilation and the lifestyle of the occupants.

How to Get an Accurate Reading in the Home

Humidity Detectors are very accurate at telling the user how much moisture is in come in all shapes, sizes and prices.

Professional units cost hundreds of pounds and provide the user with extremely accurate results.

There’s plenty of choice for the homeowner with so-called “desktop” monitors that cost upwards of £10.

You should keep a spreadsheet detailing all the readings in each room, also note the temperature as the amount of moisture the air can hold depends on the room temperature.

This humidity detector has a five-star rating and over 4000 reviews on Amazon

What is an Ideal or Normal Humidity Level?

The ideal relative humidity level for a UK home will depend on the outside temperature.

In general, around 50-55% is ideal for a typical summer and between 45-50% during a mild winter.

Issues With Low Humidity

Low humidity levels in the home can cause dry skin, itchy eyes, a sore throat and can even irritate the nasal passage.

Timber such as wood flooring and those in some cabinets or shelves may shrink and crack.

Rubber door seals, gaskets and any other materials that hold moisture may show signs of shrinkage.

Issues With High Humidity

High humidity levels are a common problem in homes that have been over-insulated.

Homeowners and tenants have reported respiratory illnesses, asthma and clammy skin.

In the home you can expect damp walls, timber cabinets and floorboards swelling, mould, and general moisture and condensation issues.

Bugs such as dust mites will thrive in a damp environment, as will woodworm and similar wood-boring creatures.

Short-Term Solution to Reduce Humidity Levels

A popular short-term solution is to run a dehumidifier. This will extract the moisture from the air and place it in a container so you can dispose of it.

They require electricity and are often noisy, hence why they’re not a suitable long-term solution.

Other options include any steps you can take to vent the property, even opening windows or leaving them slightly ajar, if it’s safe to do so.

Long-Term Solutions to Permanently Reduce Humidity

There are two causes of high humidity levels, the first is excessive moisture creation in the home, the second is a lack of adequate ventilation.

The first step is to try and reduce the amount of moisture entering the home.

Common causes are:

Drying clothes on radiators
Leaking rainwater gutters and blocked pipes.
Leaking freshwater pipes.
Blocked sewers.
Leaky heating pipes.
Leaking roofs.
Poorly constructed groundworks where rainwater flows towards and not away from the home.

Once you’ve ruled out damp penetration, the next step is to improve the ventilation in the home.

The worse culprits are usually the kitchen from cooking and boiling, the bathroom from showering and bathing, and the bedroom from perspiration.

Kitchens should have extractor fans fitted, ideally a very powerful one if the room doesn’t have a window.

Bathrooms without windows are a major cause of high moisture and humidity levels. The extractor fan should have a humidity sensor inside so it can activate and switch off automatically.

Did you know that the average human will lose over half a litre of moisture through perspiration each night? Without adequate ventilation in the bedroom, that moisture may condensate on cold windows, ceilings and walls.

Common solutions include:

Air bricks placed adjacent to floating/suspended floors (if your home has them):

Window trickle vents work very well, especially in the bedroom:

Passive input vents are a favourite of mine as they’re cheap to run and work silently and efficiently to filter out bad, foul and moist air:

Preventing damp and mould | Preventing damp and mould

Many people have experienced issues with damp and mould in their property at some point. Even in warm, well looked after properties mould growth can occur in some parts of the home, especially in the colder months. Most mould growth people will experience is most likely to be the result of condensation, however some instances of damp and mould may be the result of damp.

Below you can find some information about damp and mould in the property looking at the main sources and some helpful tips for how to minimise damp, condensation and mould in your home.

Causes of dampness and condensation in your house

Lack of adequate heating and/or ventilation.

Water coming in from the outside through leakage, seepage

Rising damp – dampness from the ground rising up into the building fabric

High levels of moisture/water vapour being produced inside the house

Why it is important to keep a house dry as well as warm

Moulds and other fungi can grow in damp homes, particularly in areas where there is restricted ventilation, such as inside cupboards and wardrobes.

Humidity

Air contains moisture – this is called humidity. The higher the temperature of the air the more water it is able to hold. Air at 20°C can hold a lot more moisture than air at 10°C. The term ‘relative humidity’ describes how much moisture air contains at a given temperature. 100% relative humidity means the air is holding as much moisture as it can at that temperature.

The more humid the air is in your house, the more energy it takes to warm your house because it is also warming the water in the air. This means it will be more expensive to heat!

A good range of indoor humidity for comfort and health is between 30-60% during cooler months of the year. Mould is likely to occur if the relative humidity indoors is 70% or more for long periods of time. Keeping humidity levels under 50% also helps to minimise or control dust mites. But it is also possible to live in a house that is too dry! Humidity levels below about 30% lead to dry skin and nasal passages, increasing the potential for respiratory illnesses.

It is worth buying a low cost humidity meter from a hardware store and track how humid the air in your house is. You might be surprised at how quickly it can change, from morning to night, from room to room, and as the weather changes.

Humidity and condensation

When the humidity is high inside a house and it is cold outside the water vapour condenses on cold surfaces. The following areas might have problems with condensation and dampness:

Cold surfaces such as mirrors, windows, and metal window frames (‘crying’ windows)

Kitchens and bathrooms

Solid, uninsulated walls of unheated rooms

Cold corners in unheated rooms, particularly where outside walls meet

Wardrobes, cupboards.

Humid air and condensation can also be generated by things people do in their homes on a daily basis.

Sources of humidity and damp

Table showing sources of humidity and damp
Source of humidity/moisture	Litres of water vapour
Cooking	Up to 3 litres per day
Clothes washing	0. 5 litres per wash
Showers and baths	1.5 litres per person
Washing dishes	Up to 1 litres per day
Un-vented clothes drying	5.0 litres per load
Unflued gas heater	0.5-1.0 litre per hour of use
Breathing, active adult	0.2 litres an hour per person
Breathing, adult asleep	0.02 litres an hour per person
Pot plants	A high number of pot plants or if you frequently water them will increase humidity in your house

How to keep your house dry and avoid condensation

There are lots of things you can do to minimise dampness and condensation in your house.

Four key actions

Reduce the amount of moisture produced in the home

Provide ventilation, particularly in moisture-prone areas

Increase heating to raise the temperature of the air and the cold surfaces

Insulate the building to warm up cold surfaces and keep the heat in

Low cost options

On dry days open some windows to allow humid air to ventilate out of the house. It is better to open a few windows a little throughout the whole house. This helps the air to move through the house. One window open wide in one room may not be as effective. Try to do this as often as possible (2-3 times a week), but keep windows closed on wet days as damp air may increase indoor humidity.

Keep lids on your pots and pans when you cook – simmer rather than boil hard.

Keep the doors to the bathroom and kitchen closed when you are bathing or cooking.

Use thermal or lined curtains, keeping them open in the day and closed before dusk. This will capture the free heat from the sun and help to lift indoor temperatures.

Always wipe excess moisture from windows – if you don’t the moisture will collect on the frame which may start to rot. It may also re-evaporate during the day, raising humidity levels and making condensation worse when the room cools down.

Limit the number of pot plants in your house.

Install temporary plastic window insulation kits on your windows for the cooler months of the year.

Keep furniture away from outside walls to allow air circulation. Cool areas behind furniture will be high humidity areas conducive to mould growth.

Heating

On cold days try to keep indoor temperatures at least 18°C.

Try not to use a portable gas heater. They create high levels of humidity and are expensive to run. They also release harmful gases into the air.

Where possible install efficient heating, suitable for each of the rooms being heated

Install a heater in your bathroom.

Dehumidifiers extract moisture from the air and can help reduce humidity. However they do not tend to solve underlying problems of moisture getting into your house, excess moisture production in the home, and lack of ventilation and heating.

Drying clothes

Wherever possible, dry your clothes outside.

If you use a clothes dryer, make sure that it is vented outside.

If you must dry your clothes on a clothes rack inside, do this in a well-ventilated room with doors closed to the rest of the house.

How humidity damages your home — and how to fight it

Learn how to tackle excess moisture and dry air, which can both cause damage to different parts of your property.

Introduction

When humidity in your home is too high or too low, it can make living conditions unpleasant, and it can also do lasting damage to the property.

High humidity creates excess moisture and condensation that potentially leads to mold or rot, while low humidity has been linked to the rapid spread of viruses like cold, flu, and even Covid-19.

In this article, we’ll discuss how bad humidity can cause damage to your physical property, fixtures, and fittings. We’ll cover how to tackle existing problems. and how to make sure the conditions are right in your home to prevent future damage.

What is humidity?

Humidity is simply the concentration of water vapor present in the air, while relative humidity measures the amount of water in the wait in relation to the maximum amount of water vapor it can hold. For example, when outdoor humidity reaches 100%, the air cannot hold any more moisture and it starts to rain.

In warmer temperatures, the atmosphere can hold more water vapor so, typically, turning up the heating in a room will cause relative humidity to fall. However, there are many different factors that cause these values to vary.

Drying laundry, a boiling pot, or a hot bath are all likely to cause humidity levels to rise, while ventilating a room properly will cause levels to fall, even though it generally makes the air cooler.

Research from the Building Science Corporation found that humidity of 70% or higher adjacent to a surface can cause serious damage to the property. The Health and Safety Executive recommends that relative humidity indoors should be maintained at 40-70%, while other experts recommend that the range should be 30-60%. Most people find 30-60% most comfortable and this is the level that Airthings recommends.

How high humidity causes damage in your home

High humidity can cause problems in your home if relative humidity regularly exceeds 60%. When the air contains water vapor above that level, mold and mildew start to grow, while excess moisture can cause rot, damaging your belongings. Let’s look at some potential problems.

Growth of mold and mildew

These microscopic fungi are all around us, but in damp parts of the home, they find the perfect conditions to settle on surfaces and grow. Mildew usually refers to the white or grey patches that form on surfaces like shower curtains, windowsills, or tiles, while mold is black or dark green in color and can penetrate deeper into building materials.

Mold can cause health problems, like asthma in children, as well as triggering allergies.

If mold growth is not controlled, it eventually destroys the things it lives on, because the fungus gradually digests materials. This might mean that items like soft furnishings, books, carpets, or soft toys have to be thrown away. In more serious cases, it causes weakened ceilings or walls, and undermines the structural integrity of buildings.

Damaged paintwork and peeling wallpaper

The walls of your home are a prime site for condensation to gather, if high humidity is not controlled. The issue is particularly acute with exterior walls, as it’s here that warm, humid air meets a cooler surface.

Flaky paint or curling wallpaper is a sign of excess moisture in the home. It’s important not to just paint or paper over the problem without dealing with the damp, because it won’t go away.

Rotting furniture, floors, and furnishings

Excess moisture in the home due to high humidity can damage wood, either by creating stains and growths, or eventually by causing more serious decay. When furniture is placed close to outside walls, there is a higher risk that damp will set in.

In the most serious cases, when a problem with excess moisture goes on for a long time, it can cause irreversible damage to hardwood floors, window-frames, and other wooden fittings.

Damaged walls and brickwork

The walls of your home will generally have air/vapor barriers, intended to prevent warm moist air penetrating the surface, but these are never perfect. Especially when the weather is warmer, moisture can condense in foundation materials, crawl spaces, and basements, leading to problems with the structure.

When the moisture content in plaster, joists, or studs is constantly changing, it causes materials to swell or contract. As a result, high humidity can lead to cracks, which may call for potentially expensive repairs.

How to prevent high humidity in your home

The good news is that you can take some simple steps to deal with high humidity in your home, with the help of good quality information about the humidity levels in your property.

The things we all do in our houses every day: washing clothes, taking baths or showers, cooking, and even breathing, generate moisture, but we can limit humidity problems in the home by minimizing this moisture and letting it escape.

Firstly, take steps to ensure that water can’t get into your home, by checking your roof and brickwork regularly, particularly after winter storms.

Make sure your property is properly ventilated. That could be as simple as cracking open a window, but make use of fans and air conditioning too. This is especially important in rooms like the kitchen, the laundry, and the bathroom. When you’re cooking, use the ventilation hood, and activate extractor fans in the bathroom or laundry.

Humidity causes fewer issues if your home remains properly and consistently heated. Try to maintain a relatively constant temperature, even if it means turning down the thermostat a little, but keeping the heating on for longer. As a result, there will be less opportunity for warm air to cool and cause condensation.

In addition, avoid drying clothes indoors, if you suffer from high humidity. Hanging wet towels or other items on radiators is a common practice that creates humidity as the moisture evaporates, increasing the risk of humidity damage in the home.

Finally, by installing indoor air quality monitors you will be alerted to any potential problems, and have historical data, so you can see where persistent issues arise. Humidity sensors are an essential part of any air quality monitor, as they provide a detailed understanding of potential issues regarding moisture in your home. Avoid problems and optimize conditions with minimum fuss.

How to fix high humidity in your home

So if you already know that you have high humidity problems in your home, what can you do about it? Many of the prevention measures are also effective in dealing with existing issues.

Ventilation is key, and the simplest remedy is often to open windows. A more lasting solution could involve installing air conditioning, to get air circulating through your home, which will carry the moisture away. Alternatively, a dehumidifier draws moisture from the atmosphere, causing humidity to drop.

If you don’t have effective extractor fans in bathrooms or laundry rooms, or the ventilation hoods in your kitchen aren’t working well, you may need to repair or replace this equipment. Make sure that washing machines and tumble driers are plumbed in properly, and vented so that moisture escapes as it should.

How low humidity damages your home

How low should you let humidity get in your home? As we’ve discussed previously, ideally the figure should not drop below 30%. At lower humidity levels, the effects can include dry or itchy eyes, dry skin, and infections spreading more rapidly.

Dry, low-humidity air also causes physical damage to the home. Wood contains a certain amount of water, in ideal conditions, and when it loses too much moisture in dry air it experiences shrinkage. This can result in serious damage to flooring and furniture, or shifting window panes. Low humidity can also generate excess static electricity, which sometimes affects electrical equipment and computers.

How to prevent low humidity in your home

To prevent low humidity in your home, you should find ways to add more moisture into the air. For example, you might want to leave a door open to let steam escape from the shower. Or you could choose to air-dry clothes indoors. You could turn down the heat or boil a pot of tea on the stove. Think about investing in some pot plants too as they release moisture into the air. All of these actions will increase the humidity in your home. But be careful you don’t overdo it, and end up with a problem of high humidity as a result.

How to solve low humidity in your home

If you have persistently dry air, you might want to consider installing air conditioning or a humidifier to get the conditions right. To make sure that you’re doing the right thing, and to avoid going too far and encouraging high humidity, it’s important to understand the air quality in your home.

An indoor air quality monitor will provide real-time and historical data on humidity, as well as other metrics, so you know exactly where problems exist and where they could potentially arise.

KEY TAKEAWAYS

High humidity over 60% can encourage mold and mildew, and damage furniture, wallpaper, paintwork, floors, and brickwork.
To help combat high humidity problems, heat your home properly, use ventilation, and keep moisture-creating activities to a minimum.
Low humidity causes wood to shrink, which can damage furniture, floors, and window panes. It can also affect electronics.
Heating and ventilation can help to control low humidity issues, while a humidifier stops the air from getting too dry.
Using an indoor air quality monitor gives you detailed data on humidity, so you can deal with issues and avoid damage to your property.

With the cold weather now well and truly upon us, it’s inevitable that we’ll reach for the thermostat, crank up the heating and close windows and doors in an attempt to keep the environment toasty for the next few months. Seems like the right thing to do, however, comfort-obsessed Brits could be turning a blind eye to the invisible dangers of humidity that come with living in a warm and under-ventilated living space.

New research, commissioned by Ecoair , shows that despite 79 percent of Brits having lived with damp, mould or condensation in their property, over one in five (21 percent) are unaware of the issue of excess moisture in their homes, which can have serious effects on health. What’s more concerning is that 17 percent don’t believe humidity can have any negative impact on our health at all.

Ecoair co-founder and MD, Sally Fok, provides expert guidance and analysis of the research findings to ensure a healthier, humidity-free home this winter:

Why are our homes more humid in the winter?

(Image credit: Future PLC/ Polly Eltes)

By turning on the heating and closing doors and windows during winter, we significantly reduce air circulation, causing moisture generated inside to become trapped indoors. Moisture from rain and melting snow can also enter our home through windows, floors or walls – particularly in older buildings.

In the meantime, condensation of moisture on cold surfaces such as windows, ceilings, floorboards and walls, due to the difference between indoor and outdoor temperatures, is a major cause of trapped excess moisture in all homes throughout the winter.

Do you suffer from allergies? READ: Keep your home healthy by cutting down on allergens

How are we exacerbating the problem?

(Image credit: Future PLC/Tim Young)

A huge majority of us are inadvertently making the problem worse and therefore putting our health at risk. It’s a common misconception that turning the heating up will reduce humidity, however, warm air carries more moisture!

Humid air in a warm interior will find any colder surface, such as windows or walls, to condense, generating more condensation. Closing windows and curtains, air drying or hanging laundry on the radiator, taking long baths or showers, blocking vents, draughts or gaps, boiling the kettle, cooking, even breathing… can all contribute to the build-up of excess moisture in our homes.

Airborne microorganisms thrive in humid conditions. The survival and breed rate of bacteria, viruses or dust mites for example, will escalate as soon as humidity levels rise above 60%. This level of humidity is not at all uncommon in UK homes during the colder wetter winter months and the visible signs do not necessarily present themselves immediately.

Visible signs of humidity include damp, mould, mildew, condensation, rotting or warped wood, peeling paint… If these are present, humidity in your home is way above optimum levels, so it’s vital to act quickly. As well as risking your health, you’ll likely also end up with costly damage repair bills.

Why is humidity particularly dangerous for children?

(Image credit: TBC)

Children have weaker immune systems so there is an increased chance of them catching infections. Bacteria and viruses thrive and spread rapidly in a humid environment, so once an infection is brought home by any member of the family, excess moisture present in the air will increase the risk of everyone else in the house becoming infected.

A humid environment will also aggravate existing conditions such as asthma or eczema and can trigger numerous allergies. So to keep children healthier and defend against winter bugs during the colder months, it is strongly advisable to check humidity levels and ensure they remain below 60%.

How can we monitor the levels of humidity in our homes?

Moisture levels can be measured by using a hygrometer. These are widely available online, inexpensive and will provide peace of mind. Any reading above 60% and it’d be strongly advisable to take steps to address the problem. It’s important to test all living spaces; it may be that the excess moisture only occurs in specific rooms.

How can we protect ourselves against excess moisture build up?

Ventilate. It is SO important. Good air circulation – even in winter – will allow excess moisture to escape and is key to warding off illness. Open windows regularly and use vent fans every time you are cooking and after taking a shower or bath. Allowing the air to circulate is a quick way to release trapped humidity.

For those looking for a more immediate and controlled solution or in the case where humidity is continually showing levels higher than 60%, the best dehumidifiers can successfully restore and maintain the correct moisture levels in the home by extracting moisture from the air. Once humidity levels in the home are brought down to below 60%, airborne bacteria and viruses will not only stop breeding, but will struggle to survive.

To control heavier cases of condensation on windows, damp or mould, it is advisable to bring the humidity down to 40% during the winter months.

How are you protecting your house from humidity this winter?

weather and climate in the UK

CLIMATE

The Kingdom of Great Britain is an island state located in the northwest of the European continent. The country has 5,000 islands. The area of the entire territory is 315 thousand km2. London is the capital of Great Britain, located in the southeast of the kingdom.

The country is washed by the Atlantic Ocean and its waters of the Irish and North Seas. Great Britain is separated from continental Europe by the Pas de Calais and the English Channel.

The relief of the kingdom is varied. In the northwest, the country is embraced by the Pennine and Cumberland mountain systems. In the southwest rise the hills of Exmoor and Dartmoor. And the center of the state is given to the lowlands. In the Scottish region, in the north, the Mid-Scottish Lowland and the North Scottish Plateau are distinguished. In the center and north of Wales (the central west of Britain), the relief is also characterized by highlands. And in Northern Ireland, significant relief zones are located in the south, it is occupied by the Morne mountain range. Of the natural reservoirs, the first to note is Loch Ness in Scotland. Its depth is 229m, and in Loch Marble 309 m. The longest river in the UK is called the Severn, followed by the Thames.

The weather in Great Britain is associated with the warm current of the Gulf Stream. The south of the state is usually warmer than the north, and it is drier there. The country is exposed to northwest winds brought by the Atlantic Ocean. Rainfall varies from 553 mm to 3000 mm per year.

Climate in England by months of the year

Traveling in England can be bright and unforgettable at any time of the year. Although the country is located in the north, Great Britain provides an opportunity even for a beach holiday, albeit not so long. The Isle of Wight is considered the sunniest and most suitable for a beach holiday resort in England, where Queen Victoria introduced the fashion for holidays among the aristocracy.

A great variety of different festivals, mass cultural and sporting events, traditional folk festivals provide opportunities for tourists with completely different goals to enjoy their holidays in England. After all, even in winter this northern country is not covered with snow, and the inhabitants do not fall into “anabiosis”.

Many tourists do not pay attention to the climate here by months, because you can learn about the traditions of the British, their history and culture at any time of the year.

Sub-zero temperatures even in the middle of winter in the country are rare, because the island has a temperate climate, which is formed due to the warm Gulf Stream ocean current. The weather in the north and east of the country is less affected by the maritime climate, which makes these regions colder than the south of England and its capital, London.

In turn, the south of Great Britain is subject to frequent fogs and regular rainfall. The winter and summer seasons in England are considered moderately warm and humid.

England in winter

December is one of the busiest months for the population of the country, because the traditional preparations for Christmas and New Year are in full swing. You can’t wait for snow in December in the south of the country; a trip to the capital during this period of time is often overshadowed by constant fogs and rains. This feature of England has not surprised anyone for a long time, and on the contrary, it gives a mysterious melancholy charm to the country.

Cozy local pubs or restaurants with fireplaces will help to keep warm and not pay attention to what is happening outside the window. In the southern regions, the temperature varies from 0 to 8 ° C. Sometimes, due to the incessant fog in the winter, flights to England are not carried out. In the northern regions of the country, snow is not uncommon, and frosts can only occur at night.

In January, the temperature drops , however, it is not so significant. In the south of the country, the air warms up to 6 ° C, and the amount of precipitation, including sleet, and dense fogs also increases. Shopping centers will help to escape from it, where grandiose discounts are presented in January.

February is not very suitable for tourism. Frosts do not occur very often, and the amount of precipitation increases significantly. Sightseeing and walking during this period are unlikely to be comfortable, but nothing will stop you from enjoying a traditional English five-hour tea party in one of the restaurants or cafes.

England in the spring

In March, the temperature rises to 10°C , and in the south of the country it is much warmer than in the northeastern regions. March is considered the driest month in England, although the sky is still densely overcast, humidity is still high, and foggy in the mornings.

In April it becomes much warmer, the temperature does not drop below 14°C, and the local nature begins to come to life . It rains, but rarely enough, the sun is increasingly showing in the sky. Daylight hours are on the increase and the season of excursions opens in England, so be prepared that you will not be alone when sightseeing.

In May, greenery appears, so national parks and reserves look especially beautiful – they are buried in flowers . The temperature rises to 18 ° C, and the tourist season is gradually gaining momentum.

The local climate, which involves strong winds on the coast and variable temperatures, can spoil the impression of a holiday. Therefore, despite the rather high temperature, do not forget about warm clothes.

England in summer

The best time to visit England is early summer . And all because traveling around the country will be quite comfortable, because the weather is almost always clear in the absence of wind, and there is still no influx of tourists. The air temperature is about 20°C, in the evenings it is quite warm, since June you can wear light clothes.

The water temperature does not rise above 15°C, so it is too early to open the swimming season. Fans of sporting events can safely go to the Wimbledon tennis tournament at this time.

July is the warmest English month of the year. The average temperature is about 25°C, and the water temperature rises to 18°C.

In the evenings, slight cooling is possible, and in the mornings it can often rain for a short time. The clouds are still the same as usual, but this does not prevent you from taking air baths on English beaches. There are a lot of sandy beaches in the country. At high tide, the water is much warmer, but swimming becomes unsafe.

In August, the heat slowly subsides, the weather is no longer the same as before . This contributes to the fact that moisture is transferred much easier. There are rare showers, but they pass quickly. There are more tourists, and the number of students enrolling in various training courses is also growing.

In addition, the football season opens at the end of summer, and thousands of fans flock to Beckham’s country to see a bright first-class game. Also famous is the Peterborough Beer Festival, where you can have fun and try several varieties of intoxicating drink.

England in autumn

In September it starts to get colder, the rains become longer and more frequent . The foliage begins to turn yellow, which makes the landscapes in the parks incredibly beautiful. Evenings are still not very cool, so you can still go for walks and hikes. Swimming is no longer worth it, because the temperature rarely rises above 20 ° C.

In October, England appears to everyone in a melancholy way, when rains and fogs become ordinary and regular, and the air temperature drops to 15 ° C. Strong winds do not contribute to comfortable viewing sights, which makes it better to go inland, as far as possible from sea storms that affect the climate on the coast.

In November, the weather on the island is quite unpredictable, it can snow along with rain.

Hurricanes can occur on the coast, so when you find yourself in England at this time, it is better to plan cozy gatherings in local pubs with traditional English cuisine or private entertainment (amusement parks, shopping centers, museum, art galleries).

Temperatures are already close to winter and do not rise above 9-12°C. Halloween is celebrated in England for several days in late October – early November, so a holiday, despite the weather, guarantees fun.

Of course, you should pay attention to the climate before you go to England. However, you can learn about the traditions of the country, see the royal palaces, galleries, museums, famous monuments and squares at any time. When given the opportunity to visit a country, the climate should not be the main criterion – England is beautiful and majestic at any time of the year.

Geography and climate of Great Britain

The United Kingdom of Great Britain and Northern Ireland is an island nation located off the northwestern coast of continental Europe. The island is separated from the mainland by the English Channel. The minimum distance of the southeast coast of the country to the northern coast of France is only 35 km. The United Kingdom consists of four geographical and historical parts of England, Scotland, Wales and Northern Ireland, located in the British Isles (group of islands: Great Britain, the north-eastern part of the island of Ireland and many small islands and archipelagos in the Atlantic Ocean).

The capital of Great Britain – London is one of the world’s leading commercial, financial and cultural centers. The distance between the Russian and British capitals is 2,500 km. A flight from the central part of Russia usually does not take more than 4 hours.

The country of 62.8 million people ranks 78th in the world in terms of area of 242,514 km2.

Great Britain is located within just one time zone. London Greenwich is located on the prime meridian and is officially the zero point of reference for time zones.

Climate

The climate of Great Britain is temperate oceanic, mild and humid (wetter in Northern Ireland and colder and drier in Scotland). The weather is mainly influenced by the warm ocean current of the Gulf Stream. The sea, washing the country on all sides, does not allow the air above the land to get too warm or cool. Therefore, sudden changes in temperature rarely occur, but the weather conditions are quite changeable.

The climate throughout the territory is represented by four different regions:

southeast – cold winters, warm and dry summers
southwest – mild and very wet winters, warm and humid summers
northwest – mild winters, cool summers and frequent rain throughout the year
northeast – cold winters, cool summers and steady rain throughout the year

Northern Ireland has a temperate mild and humid climate with mild winters and fairly cool summers. The warmest month is July, the average temperature is 19C. The coldest month is January, the average temperature is 8C. Precipitation and foggy days are less here than in England. On average, from 1,200 mm to 1,600 mm of precipitation falls annually.

Scotland is the coldest region in the UK. The instability of the weather is associated with a diverse relief. In mountainous areas, temperatures can reach 10 degrees below zero in winter. January and February are the coldest months, with an average temperature of 3C. Heavy fogs and rains 250 days a year. The warmest months are July and August with an average temperature of 19C. About 3,810 mm of precipitation per year falls in the west of the region, in the eastern parts – about 635 mm per year.

The climate in England is unstable, with frequent fogs and gusty wind storms. The average temperature in winter is +5C. In spring, there is less precipitation, but cold northerly winds blow. In summer, the temperature ranges from +16 to +32. August has the most rainfall. In autumn, cyclones prevail and fogs begin.

London has a mild and temperate climate. Summer is warm but not hot. In recent years, there has been an increase in temperature. In 2003, the temperature reached a record high of +38C. And the autumn of 2011 set new temperature records – at the end of September the temperature rose to +29C. Fog formation occurs most often in January and February. There are only about 45 foggy days in London these days, but half the days of the year are cloudy and overcast. The average summer temperature is around +19C. Winter is cool, but not frosty – on average, the temperature does not fall below 7C. Snowfalls are rare, the snow cover is only about 25 mm. And the average annual rainfall is less than in Rome or Sydney – about 584 mm.

Wales has a mild and humid climate similar to England. In January the average temperature is about 5C, in July 16C. The area of the Snowdon massif is the wettest – 2540 mm, in the central coastal region about 762 mm per year.

Weather

Even if you’ve never been to the UK, you’ve probably heard about its changeable, wet and poetic weather, which has become an endless topic for jokes and anecdotes. Weather in the UK is the most frequently discussed topic, and when meeting any resident of the country, the first thing they will ask is what do you think about the weather. Due to its geographical position, the coastline of the island is often immersed in sea fogs caused by the warm Gulf Stream evaporating in the cold Atlantic air. In terms of weather conditions, Foggy Albion is deservedly considered the most unstable place in Europe. In recent years, there has been a trend towards increased unpredictability of local weather. Therefore, one should trust the testimony of weather informers more than long-term statistics.

We base comfort level on dew point, as it determines whether sweat will evaporate from the skin, cooling the body. A lower dew point makes you feel more dry, while a higher dew point makes you feel more humid. Unlike temperature, which typically varies significantly between day and night, dew point tends to change more slowly, so while temperatures may drop at night, a wet day usually gives way to a wet night.

The perceived humidity level in London, measured as the percentage of time that the level of humidity comfort is damp , stuffy or heavy , does not change significantly throughout the year, remaining almost constant 0 % .

Temperature and dew point

There are 2 weather stations close enough to help us estimate the temperature and dew point for London.

For each station, the data are corrected for the difference in altitude between the station and London according to the International Standard Atmosphere, as well as for the relative change in MERRA-2 satellite-era reanalysis between these two points.

The estimated value for London is calculated as a weighted average of the individual data from each station, with weights proportional to the reciprocal of the distance between London and the given station.

Stations participating in the reconstruction:

Why is mold so fond of British homes and how to get rid of it?

Mold in houses and apartments is a headache for many people in Britain. In addition, due to the warm winters recently, the amount of mold in English houses has begun to grow in both long-built and modern buildings.

The main reason for mold growth is humidity and relatively warm climate.

According to statistics, every fifth house in England suffers from black plaque on the walls. The main reason is that in many homes there are ideal conditions for the appearance and continued existence of mold, namely:

– high humidity and dampness due to weather conditions;
– violations in the operation of ventilation and heating systems;
– leaks in roofs due to frequent rains.

Fungal colonies thrive in these conditions and will continue to grow if not removed.

Mold is very easy to hide. Some property owners often sin with this when selling or renting out housing. One has only to repaint the walls, and the signs of the fungus will not be noticeable at first.

Mold most commonly occurs in timber buildings, older structures, or improperly installed sealing materials that help retain moisture.

If you want to rent or buy a home, you should carefully inspect not only the apartment, but the whole house, especially you need to check the humidity level in the basement and basement. It is also necessary to find out what material the building is built from, to check how efficiently the waterproofing and sealing systems work, and if there are any cracks in the walls. In order not to be mistaken, it is better to order an expert assessment of the premises – is there a fungus in it?

Dangerous colonies

Mold can seriously harm your health – it’s been proven. First of all, it can provoke the appearance of problems with the respiratory system. The result is various allergic reactions, exacerbations of which affect the nervous system, which leads to sleep disturbance, migraines, dizziness and fainting. In the most serious cases, mold can cause asthma, bronchitis, and pneumonia, and it can also contribute to the development of lung cancer.

What the experts say

Geoff Charlton, one of the UK’s leading experts on mold research, outlines the steps to successively combat mold: “Mold falls into two categories: ‘live’ and ‘dead’. The latter is more dangerous for human health than the former, because it releases more harmful substances into the air. Any hint of mold in the room should be taken immediately. First you need to find the root of the problem, why the fungus appeared in your house. Most likely, the matter is an excess of moisture. To get rid of mold forever, you need to take a number of serious steps:

– examine mold and determine its type;
– identify and eliminate sources of moisture;
– remove all plaque;
– Disinfect affected surfaces.

Control Methods

One of the most effective mold control methods is the use of specific chemicals such as Black mold remover and HG Mold Spray. But do not forget that the excessive use of chemicals, firstly, is not suitable for everyone, and secondly, it can also adversely affect your health.

Therefore, we have selected three effective ways to fight mold naturally.

— Hydrogen Peroxide

Hydrogen peroxide is effective in killing mold on a variety of materials. Pour a 3% hydrogen peroxide solution into an aerosol can, spray the moldy surface completely, and leave for ten minutes. Then clean the affected area to remove all plaque.

– White Vinegar

Pour it into a spray bottle, then spray vinegar on the moldy surface and leave for an hour. You can also add baking soda to the vinegar solution.

– Baking Soda

Add one quarter tablespoon of baking soda to a spray bottle with water, shake until baking soda dissolves. Spray the moldy area, then use a cleaning brush to remove any remaining mold. Rinse the surface with water.

If the situation is running, you should seek help from professionals – special services, such as b idvine.com, condensationcured.co.uk or environpropertyservices.co.uk . First you need to leave a request on the website or by phone, after which you will be contacted, specialists will arrive, assess the scale of the work, give a free consultation and orient you at the final cost.

The average cost of mold removal in London is from £100 to £250 per room, depending on the level of infestation.

Farewell forever!

To prevent mold from coming back to you after expensive removal, you should use anti-humidity devices (air dryers, or dehumidifiers). The price for them varies from £40 to £450. The humidity level in the room should not rise above 40%. Sometimes they are provided free of charge by the real estate agency with which you rented an apartment or house.

Do not save on heating, ventilate the room more often. Mold will also be kept away if the house has devices for forced ventilation: air intake grilles, fans, air filters.

Static Control

Eliminate electrostatic charge
by humidifying the air
and controlling the humidity

Air humidification is an effective way to eliminate electrostatic discharge in the workplace. When the relative humidity is maintained at 55%, the moisture in the air is a natural conductor that grounds potential static charge.

Electrostatic buildup in manufacturing equipment often leads to reduced productivity, poor product quality, safety issues due to uncontrolled sparking, and physical damage to equipment, especially electronics and printed circuit boards.

Static electricity problems are common in the packaging, printing, pulp and paper, plastics, textiles, electronics, automotive and pharmaceutical industries.

For an electrostatic charge to form during friction, the relative humidity of the air must be below 45%. At a relative air humidity of 45-55%, an electrostatic charge still accumulates, but to a lesser extent, since it is discharged to the ground through the moisture contained in the air. Maintaining relative air humidity above 55% is guaranteed to prevent the formation of an electrostatic charge.

For large rooms such as printing and production halls, direct room humidification is an effective and economical solution. In the ceiling zone, nozzles are installed that spray moisture and raise the humidity of the air to the required level.

However, industrial equipment generates heat and reduces the relative humidity of indoor air, which leads to the accumulation of electrostatic charge. Heating dries the air, and in a room with a total relative humidity of 60% at 18 °C, local air pockets with humidity below 45% can form. If such equipment also generates friction leading to a buildup of static electricity, there is a risk of electrostatic discharge.

Where required, local spray systems can be installed to locally increase the humidity. By installing separate nozzles directly above the process equipment, the accumulation of electrostatic charge can be eliminated by maintaining the required relative humidity of the air as the temperature rises.
