Breathing problems can be caused by the amount of humidity that’s in the air. Humidity levels vary with the season, weather and where you live. It’s typically higher in the summer and lower in winter. 

What causes Humidity?

We’re all likely aware of humidity and have felt the affects of it in one way or another but what actually causes it?

Put simply – humidity occurs when water vapour mixes with the air. The warmer the air, the more vapour so the more humidity. Humidity affects the amount of the allergens in the air, as again, the warmer the air, the more allergens can grow. An allergen is any substance that can cause an allergy  – and they love to grow in humid environments. The allergens are what can aggravate breathing problems. Allergens can be mould, dust, pollen or chemical related. So this is why you feel can be affected in hotter weather. 

It’s well known that high pollen counts in the summer can trigger hay fever and start you coughing, sneezing and reaching for the hay fever tablets and tissues.

However, there are other factors in warm weather that you might not realise affect your breathing, that all come from your home – particularly in your furnishings and surfaces.

Everyday materials found in your house such as sofas, wardrobes or wooden flooring, naturally contain and give off chemicals over time. Don’t worry – they aren’t hazardous or life threatening! However they can contribute to breathing and health issues if they’re not kept an eye on or regulated. The amount that’s given off and gets into the air increases in warmer humid weather, as they react and grow with water vapour so this is how respiratory problems can flare up.

Breathing problems can also be set off by mould and damp. Heat and humidity is the perfect environment for them to thrive and grow easily. If you have sensitive airways and are susceptible to mould and damp and other allergens then mix this together with a humid home and you’ve got the perfect recipe for more sneezing, wheezing and a tight chest. 

This also means they can easily build up on your home’s surfaces, kitchen worktops, bathrooms and furnishings. 

If you don’t have good enough ventilation to tackle this and maintain fresh air and keep healthy humidity levels, then chances are you’ll start to feel it. 

Take a look at the PIV systems on our products page to see how you can improve the ventilation in your home and regulate the humidity so its constantly kept at a comfortable level to ease your breathing problems.

Improving the ventilation in your home will also stop mould growing as less humidity means less water vapour for the mould to grow.

It’s worth knowing that the ideal humidity level for comfort in your home is between 30% – 50% so if you can keep it somewhere between this then you’ll be much more comfortable, healthier and you’ll be able to breathe easy.
