- Types of cooling mattress
1. Choose a cooling mattress topper
Many people choose cooling toppers as a great way to cool their mattress down. They also provide an extra touch of comfort.
If you don’t know what a topper is, it’s a layer that sits on top of your mattress to give it a new lease of life.
The Sleep Geek says...
The gel within the topper feels cool to the touch when you initially get into bed, although the temperature will eventually equalise during the night.
The Sleep Geek says that alternatively, natural fillings can help your body manage temperature throughout the night This is in part due to the material’s ability to wick away moisture efficiently.
All you need to do is pick the cooling topper that suits you best to feel instantly cooler as you fall asleep. They're easy to remove, too, so you can take them 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. By using a cooling gel pillow, you will feel a difference in your overall body temperature while the pillow stays cool.
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. Pillows with natural fibres can help you to manage the heat all through the night.
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.
The Sleep Geek says...
James points out that some people might find this a little cold. However, for a better night’s sleep, it is best to have the bedroom feeling a little cooler than the rest of the house.
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:
- 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 gets circulated around the room
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 will allow 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 your bedding
No matter how you sleep, your bedding makes a huge difference to your sleeping experience. Here we explain some changes you can make to your bedding that will help keep your mattress cool at night.
Change your sheets
It's always best to buy sheets made from natural materials such as cotton, linen or bamboo. This is because they're more breathable and can wick away moisture if you overheat easily. They're super soft and comfortable while allowing you to stay cool through the night.
The Sleep Geek says...
The Sleep Geek says cotton sheets give better moisture absorption than man made fibres. However, their higher thread count bedding can reduce airflow. For superior heat dispersion, as well as excellent moisture absorbing properties, James recommends bamboo sheets.
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.
The Sleep Geek says...
James says a lukewarm shower before bed can help you feel cooler at bedtime. Similarly, filling a hot water bottle with lukewarm water and resting your feet on it will raise your core temperature slightly so you can feel the benefit when it drops.
And if you don’t have a hot water bottle, why not put your bare feet in a bowl of lukewarm water.
And if that still isn’t enough, simply go to bed in your pants!
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.
The Sleep Geek says...
For all those couples out there, the Sleep Geek has a golden tip that will help you peacefully on those hot nights: separate duvets.
James says that with separate duvets, not only can you choose the weight that suits you best, but you also avoid your partner’s heat entering your immediate sleeping environment and heating you up.
7. Try using a hot water bottle
It might seem weird for us to suggest a hot water bottle, but you could try this.
- Fill up your water bottle and then put it in the fridge
- When you're ready to go to bed, simply take it out of the fridge and put it under the covers
- Half an hour before you go to bed, remove it from under your duvet so your bed feels cool but not freezing when you get in
8. Adjust your clothing
By making simple changes to what you wear in bed, you can dramatically reduce your body temperature during 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:
|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 its pros and cons.
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.
This base is often found on divans. It is a solid block that your mattress rests on. These bases are good if you want to make your mattress more supportive. They can be a slightly warmer option.
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.
11. Invest in a cooler mattress

Types of cooling mattress
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 your mattress feel cool and fresh as you go to bed. 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.
Plant-based latex can feel cooler than standard memory foam as its natural material regulates temperature organically without the aid of gel or other substance. This means they are less likely to retain body heat, reducing your chances of overheating during the night.
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. So this eco-friendly mattress could be the perfect fit for you!
If you want to find out more about this type of mattress, check out our guide on latex 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, bamboo 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.
Now you know how to cool your mattress! By making small changes to your bedroom and sleeping environment and customising your mattress, you'll be able to enjoy a fresh and cool night's sleep in no time.
