All of us find it difficult to fall asleep when it's too hot, especially during the summer months. Tossing and turning, sweating, or feeling restless can all make it hard to get a good night's sleep. Factors like bedding, room temperature, or individual metabolism contribute to a warmer sleep.
In this article, Ru9 will help you achieve a more comfortable sleep, from changing the temperature in your bedroom to changing the way you sleep.
1. Add a cooling pad
Cooling pads are a great way to cool down your mattress while providing a more comfortable sleeping experience. Cooling pads made of breathable material play an important role in ensuring the mattress temperature remains pleasant. In addition, they protect the mattress from stains and odors, as they are easy to wash and maintain.
All you need to do is choose the right cooling pad for you and enjoy a good night's sleep immediately. They are also easy to remove, so you can rotate them depending on the season or your body temperature at night.
Our suggestion for you is Ru9's IceGuard™ cooling pad, which features modern IceFiber™ cooling technology to effectively lower the surface temperature of the mattress. Yet, it's very thin and compact, not affecting the softness of the mattress or topper at all.
2. Try cooler pillow materials
You might think your mattress is the main culprit for your body getting hot at night, but pillows are also a factor to consider. When it's hot, you might notice your head and neck are much warmer than the rest of your body. This is because we typically lose about 10% of our body heat through our head and neck. By using a cooling pillow, you'll feel a difference in your overall body temperature.
Our advice is to choose pillows made of breathable, heat-dissipating materials like the Niu pillow made from Graphene Memory Foam. The Niu pillow core has optimal heat dissipation capabilities, keeping your head and neck cool and comfortable all night long.
3. Adjust your bedroom temperature
A quick and lasting way to avoid a hot back when sleeping is to make some changes to your bedroom. The cooler the space where the mattress is placed, the more the mattress surface dissipates heat and the more comfortable it is.
It's important to maintain a suitable room temperature, usually 25-26 degrees Celsius. This environment promotes good sleep hygiene and keeps your room cool enough to prevent bacterial growth.
4. Increase air circulation
This is also one of the easy solutions, which can be done in many different ways. Based on the principle of trying to get as much air as possible to circulate into the bedroom. You can close the curtains during the day and open the windows at night to let cool air flow into your bedroom.

Open windows at night for easy air circulation into the bedroom.
5. Switch to breathable fabric bed sheets
No matter your sleeping habits, bed sheets play a huge role in your body temperature.
It's best to buy bed sheets made from natural materials like cotton or linen. This is because they are more breathable and can absorb moisture if you sweat a lot. At the same time, this super soft and comfortable bed sheet material also allows you to stay cool all night long.
Typically, Percale Bedding in Ru9's cool sleep collection is made from 100% long-staple cotton, light and breathable, giving you a uniquely cool and comfortable sleep experience.
6. Use a light duvet
The best way to still enjoy coziness while keeping the mattress surface cool is to consider investing in a suitable duvet.
Stay away from duvets that retain body heat, such as polyester or silk. Instead, choose lightweight, breathable duvets made from sustainable natural materials to keep you cooler.
7. Try a hot water bottle
The suggestion of using a hot water bottle to cool your back while sleeping might sound strange, but you can definitely try this method:
- Fill a hot water bottle with water, then place it in the freezer.
- When you're ready to go to bed, simply take it out of the freezer and place it under your mattress topper.
- Half an hour before bed, place it under your blanket.
This is a great way to cool down your mattress because hot water bottles are designed to distribute heat quickly to keep you warm, but they also work to keep you and your mattress cool for longer.
8. Adjust your clothes
By making simple changes to your sleepwear, you can significantly reduce your body temperature at night.
First, always keep all clothing light and loose. Second, try to wear natural, breathable materials like cotton. Finally, tie back long hair to keep your head and neck cool!
9. Improve your sleeping habits
The body's natural heat can also make a sleeping mattress warmer. So, lowering the temperature as much as possible before bed will be very helpful.
Drinking cool water before bed provides essential hydration and refreshes you. Avoid exercising at night, as it can raise your body temperature before bed.
10. Invest in a cooler mattress
Do you want a cooler sleep all year round? Perhaps it's time to invest in a brand new mattress to meet your needs.
