1. Choose a cooling mattress topper

Cooling toppers are a great way to cool your mattress down while also providing an extra touch of comfort. A topper is a layer that sits on top of your mattress to give it a new lease of life.

All you need to do is pick the cooling topper that suits you and enjoy an instantly cooler night's sleep. They're easy to remove, too, so you can take it off depending on the season and how warm or cold you feel in the night.

2. Try cooler pillows

You might think that your mattress is the main culprit for making you overheat, but your pillow is also a big factor. When it's warm, you may notice that your head feels a lot warmer compared to the rest of your body. This is because we lose around 10% of our body heat through our head, so by using a cooling pillow you will feel a difference in your overall body temperature.

We have a wide range of cooling pillows to help you fall into blissful sleep. Pillows can have a variety of cooling properties. Some pillows can be cool to the touch and some even have air vents in their structure to increase breathability.

3. Cool your bedroom down

A quick and cheap way to cool your mattress is to make some changes to your bedroom. The cooler the room your mattress is in, the cooler your mattress will become.

It's important to get your bedroom to the right temperature for you before you go to sleep. The recommended temperature is 16 - 18°C with 30% - 50% humidity. This environment promotes good sleep hygiene and keeps your room cool enough to prevent bacteria from growing.

Here are some easy ways you can keep your bedroom at the optimal temperature:

Use fans

  • Make sure that the blades of ceiling fans are turning counterclockwise to push the cool air to the floor
  • Try placing a bowl of ice-cold water in front of the fan so the cold air then gets circulated around the room

A cooler room means a cooler mattress, so try to keep your your bedroom to around 16 - 18°C

Keep your curtains shut

Keeping your curtains or blinds shut ensures that your bedroom won't be getting any of the extra heat from incoming sunlight. This means your room and your mattress will be nice and cool by the time you go to bed.

4. Increase air circulation

Again, this seems like an easy solution but we don't just mean opening your bedroom windows. Try to get as much air circulation in your house as possible and leave all your inside doors open. This allows the cool air to flow into your bedroom.

Open the attic hatch

Heat rises, so the rooms on your ground floor are more likely to be cooler than your bedroom. Opening your attic hatch means the warm air has somewhere to escape to on the top floor other than your bedroom.

5. Swap to cotton bedding

No matter how you sleep, your bedding makes a huge difference to your sleeping experience. We've explained how you can make changes to each part of your bedding so know how to keep your mattress cool at night.

Change your sheets

It's always best to buy sheets made from natural materials such as cotton or linen. This is because they're more breathable and can wick away moisture if you overheat easily. They're super soft and comfortable but also allow you to stay cool through the night.

Try linen pillowcases

As with sheets, investing in a pair of breathable cotton or linen pillowcases will instantly soothe you to sleep and help you keep cool during warm nights.

This next suggestion may seem a little unorthodox but it does the trick:

  1. Before you go to bed, take your pillowcases off your pillows and put them in a ziplock bag
  2. Place the bag in the fridge or freezer and leave them for about an hour
  3. Remove the pillowcases and put them back on your pillows for an instantly cooler pillow

6. Use a lightweight duvet

The best way to still enjoy the ultimate cosiness of a duvet and keep your mattress feeling cool is to consider investing in a 4.5 tog duvet, the lightest duvet available.

If you'd like to find out which duvet is best for you, check out our helpful guide.

7. Try using a hot water bottle

It might seem weird for us to suggest a hot water bottle, but you could try this.

  1. Fill up your water bottle and then put it in the freezer
  2. When you're ready to go to bed, simply take it out of the freezer and put it under the covers
  3. Half an hour before you go to bed, place it under your duvet so it's already cool when you go to bed

This is a fantastic way to cool your mattress because hot water bottles are designed to distribute heat quickly to keep you cosy, but it also works for keeping you and your mattress colder for longer.

8. Adjust your clothing

By making simple changes to what you wear in bed, you can dramatically reduce your body temperature in the night.

  • Keep all clothing light and loose-fitting
  • Try to wear natural, breathable materials like cotton
  • Tie long hair back to help keep your head and neck cool

These quick alterations will help you feel cooler in no time!

9. Improve your sleep routine

Your core temperature can also make your mattress warmer, so it's useful to lower your body temperature as much as possible before bed.

Here are some quick tips:

Dos Don'ts
Put a cold compress on your pulse points - it helps to cool you down quickly Drink alcohol - it dehydrates you, which can make you feel warmer
Drink cool water before bed - it helps to hydrate and refresh you Drink caffeine - it gives you more of a 'buzz', which can make you feel stuffy
Exercise in the morning - this avoids raising your body temperature before bed Wear heavy or tight-fitting clothing - it can make you sweat more

10. Swap your bed

If you feel like your mattress is always too warm, it might be worth checking your bed. There are two types of bed base and each has their pros and cons.

Slatted base

This base is found on most bed frames. There are slats that your mattress rests on with gaps in between. These gaps allow for better airflow to the mattress, which can help to make it a bit cooler.

Solid base

This base is often found on divans and is just a solid block that your mattress rests on. These bases are more suited for making your mattress more supportive and slightly warmer.

If you'd like to find out more about the impact your base has on your mattress, our helpful guide has a lot more information.

Types of cooling mattress

Gel mattresses

Possibly the most innovative mattress material, gel mattresses have all the benefits of memory foam but without the warmth that some memory foam mattresses are associated with.

Gel foam is a type of memory foam mixed with gel beads to help reduce heat retention inside the mattress. This helps to keep your mattress cool at all times so you can stay cool and fresh every single night. The open cell structure of gel foams allows air to flow through the mattress with ease, making it extremely breathable. We have more information about gel foam on our gel mattress advice page.

Latex mattresses

Plant-based latex is a natural material which regulates temperature organically without the aid of gel or other substance. So this eco-friendly mattress could be the perfect fit for you!

Latex has elastic properties which means it's quickly able to respond to your body shape and weight so you get support exactly where you need it. Latex mattresses are less likely to retain body heat so you don't need to worry about overheating during the night. If you want to find out more about this type of mattress, check out our guide on latex mattresses.

Natural mattresses

Mattresses made from natural materials are often highly breathable and have organic cooling properties. Some examples of natural comfort fillings in mattresses are wool, cotton, silk, bambo and cashmere.

Now, you may think that some of these fillings think they make your mattress feel warmer, but they're actually great for temperature control. The fillings in natural mattresses allow air to flow through the mattress, which makes it more breathable.

This means that these types of mattresses are great for keeping you cool in the summer. To find out more about natural mattresses, our tailored natural mattress advice page has all the information you need.
