Why Staying Cool While Sleeping Is Essential 

Hot temperatures do more than make you uncomfortable. They can disrupt your sleep cycle, causing you to wake up frequently during the night and preventing you from achieving the deep, restorative rest your body needs. The result? You could wake up feeling groggy, moody, and less productive. 


The ideal sleep environment should be between 60–67°F, according to sleep experts, but achieving that during the summer often requires some creative thinking.

Top Strategies to Stay Cool While Sleeping

1. Pick Breathable Bedding 

The materials you sleep on play a huge role in regulating your body temperature. Opt for lightweight, breathable fabrics like cotton, bamboo, or linen for your sheets and duvet covers. Natural fibers wick moisture and improve airflow, keeping you cool throughout the night. 

  • Pro Tip: Steer clear of polyester, as it tends to trap heat and worsen the problem for hot sleepers. 

2. Sleep on a Mattress with Advanced Technology 


The type of mattress you sleep on has a significant impact on your overall comfort and body temperature during the night. Mattresses made with advanced cooling technologies can help dissipate heat and prevent the buildup of warmth.


A high-quality mattress designed for cooling can make all the difference. This is where Sure2Sleep’s Monterey Mattress with HyPUR-Gel technology shines. The HyPUR-Gel layer evenly distributes your body weight and enhances airflow, which helps dissipate heat faster.



Heads up! Sure2Sleep will also be adding Allay technology in its upcoming product line. Designed to optimize airflow, this small-batch technology works to regulate temperature by promoting better ventilation throughout the night. By reducing heat buildup and improving breathability, it ensures a consistently cool and comfortable sleep environment. 

3. Keep Your Room Cool and Dark 

Create the ideal sleep environment by focusing on temperature and light control. Try these tricks to cool down your bedroom:

  • Use a Fan Strategically: Position a fan near an open window to circulate cooler air, or place a bowl of ice water in front of it for a DIY air conditioner effect.
  • Block Heat with Blackout Curtains: Invest in thermal blackout curtains to prevent sunlight from overheating your space during the day.
  • Turn Off Electronics: Devices like TVs, laptops, and even your bedside lamp generate heat. Switch them off well before bedtime. 

4. Sip Smart Before Bedtime 

What you eat and drink in the hours before bedtime can affect how your body regulates temperature. Stay hydrated with cool water, but avoid alcohol and caffeine, as they can dehydrate you and increase feelings of heat. 

5. Wear Lightweight Sleepwear 

Nobody likes to be sweaty, especially when you're trying to get a good night's rest. Ditch heavy, synthetic pajamas in favor of breathable, light materials like cotton or bamboo. 

6. Use a Cooling Mattress Topper 

Adding a cooling mattress topper can dramatically improve how you sleep on hot nights. Sure2Sleep’s Gel Swirl Memory Foam Topper is engineered to disperse heat and improve comfort.


  • Hot (or Cool) Tip!: This is a great option if you are looking for a solution to the summer heat without breaking the bank. Even if your mattress is not the coolest, adding a layer that provides temperature control technology will enhance your summer sleeping.

7. Shower Before Bed 

Taking a lukewarm shower right before getting into bed can help kickstart your body’s natural cooling process. Avoid ice-cold showers, as they can have the opposite effect by forcing your body to produce heat to re-balance. 

8. Stay Hydrated

Drinking plenty of water throughout the day helps your body regulate its temperature more efficiently. Avoid consuming too much caffeine or alcohol close to bedtime, as these can dehydrate you and interfere with your ability to cool down.
