It’s official, the British summer is finally here.

Unfortunately, with amazing sunshine comes increased humidity and, for many of us, that means minimal sleep.

If you’re wondering how to stay cool at night, take a look at my guide to sleeping in high humidity here.

How Does Humidity Impact Your Sleep?

Believe it or not, a certain amount of humidity is actually pretty good for you.

You can use a device to measure your average humidity. If it’s between 30-50% then you’re at the optimum level; not humid and not too uncomfortable.

However, if it’s any higher than this you’ll be venturing into the late night ‘how to sleep in hot weather’ Google search.

High levels of humidity prevents the body’s natural moisture from evaporating, leading to that sticky and sweaty feeling that keeps you up at night.

Alongside this, it can leave you feeling congested, stuffy and pretty rotten overall.

Mould and dust mites also love the added moisture that humidity brings. Mould will grow and dust mites will thrive, so if you have any allergies, or generally find the idea of mites crawling around your bed repulsive, then you may want to find a quick solution to the issue.

How to Cool Down Your Room


If you’re finding all this humidity just a bit too much, thankfully there are few things you can do to increase your chances of getting a bit of shut eye.

To begin with, take a look at your bed sheets. Are they made from a natural fibre?

Cotton bedsheets will make your life a lot easier as they’re significantly more breathable than their synthetic counterparts. Synthetic bed sheets don’t quite have the ventilation you need to make the humidity bearable.

While you may be tempted by ultra-light silk sheets, you may want to stick with the cotton fabrics.

Silk sheets, while thin and cool, have a tendency to stick to the body when there’s added moisture in the room.

This will only keep the heat in, and worse, stop you from moving around comfortably.

Lightly coloured sheets will also help your attempts at shut eye. White, cream or even yellow are a better choice for bedsheets as they’ll reflect the light that comes through your window, whereas darker colours will absorb the sunshine and make it that much warmer.

Are Dehumidifiers Worth It?


If you’ve found yourself getting next to no sleep now that summer has arrived, you may want to think about investing in a dehumidifier.

There are two different types of dehumidifiers, with both working in different ways to reduce hot moisture in the room.

1. Refrigerant/Compressor Dehumidifiers

Refrigerant dehumidifiers draw in air through a filter and over a set of cold coils that in turn condense the moisture, and drips the water neatly into the tank below.

Personally, this is the dehumidifier I would recommend due to its effectiveness in high temperatures. Its ability to quickly condense the air makes it perfect for British summertime.

2. Desiccant Dehumidifiers

Desiccant dehumidifiers use an absorbent material to extract the moisture from the air, and heat the material in order to allow the moisture to drip into the tank below.

However, this version of the dehumidifier is much more effective in a lower temperature room such as a garage or conservatory.

Alongside this, due to the necessity of heating the material, it has a tendency to use up more energy overall.

Which Mattress Works Best for Humid Weather?


In hot weather, the last thing we want is to be stuck in the same sleeping position.

With this in mind, I recommend avoiding mattresses that conform to your shape using body heat.

While effective as an orthopaedic mattress, memory foam uses the aforementioned body heat in order to create the perfect mold.

Not only will this heat retention make your attempts to sleep just that much harder, but the fact that you’re stuck in the same position will make it pretty difficult too.

On the other hand, latex foam mattresses don’t have the heat retention quality, meaning you’ll still get your optimum sleeping position, just without the risk of melting.


The British summer comes and goes so quickly that if you don’t take the time to enjoy it, you’ll find yourself soaked in rain before you know it.

However, if it’s causing you to lose hours of sleep, it can be pretty easy to hate that humidity.

I hope that these little changes will help improve your sleeping pattern, but if you have a few other issues that you’d like to read up on, take a look at a few of my other blogs below.
