Sleeping hot is a common problem that can cause sleep disruptions and affect overall health. As a certified sleep science consultant and sleep researcher, I recommend keeping your room temperature between 60 and 70 degrees Fahrenheit to improve your sleep quality. A cooler environment can help your body regulate its temperature, allowing you to fall asleep faster, stay asleep longer, and get into those deep sleep stages you need to feel rested.
Keeping your room at the ideal temperature is just one part of achieving a good night's rest. There are plenty of temperature-regulating products available to help you stay cool and comfortable throughout the night. I consulted with experts, personally tested the best cooling comforters and the best cooling pillows, and gathered insights from Business Insider Reviews reporters and editors to compile a curated list of the top cooling essentials. Whether it's the best cooling sheets or pajamas, these handpicked items will help you stay comfortable throughout the night, so you can wake up refreshed and ready for the day, even on the hottest nights of the summer.

What we like
What we don't like
It sure would be a shame if you invested in bedding foundations designed to keep you cool and skimped on one of the best mattress protectors that sleeps cool and won't trap heat.

What we like
What we don't like
Adding a fan can significantly enhance air circulation to help you keep cool while you sleep, and lessen your reliance on AC. The Shark Turbo Blade has been a game changer with various coolings modes that range from whisper quiet to an easy breeze if you prefer a little white noise. The true differential of this fan upgrade is the "Air Blanket Mode," where the fan can pivot horizontally and provide a steady stream of comforting wind at bed height while you sleep. The versatile and height-adjustable fan also lets you twist vents in multiple directions for increased air flow. The fan has 10 settings and also oscillates.

Best cooling bed system
As the undisputed best overall bed cooling system, Eight Sleep offers advanced sleep tracking, thermoregulation, and features like a vibrating alarm clock, but it requires an ongoing subscription to unlock all its best features.
What we like
What we don't like
If gel memory foam and copper-infused foams for temperature regulation isn't cutting it for you, cooling bed systems have grown in popularity. The Eight Sleep Pod 4 is essentially a cover filled with discreet water-filled tubes that actively cool (and heat) your bed from a range spanning a chilly 55 degrees Fahrenheit to a toasty 110 degrees Fahrenheit. It fits over your existing mattress without altering the feel and is attached to a power hub that sits nearby and is the "brain" of the technology. The Eight Sleep can do a lot more than cool your bed, it also includes comprehensive sleep analytics and responds to your body's temperature and needs throughout the night using AI to help you stay asleep, though these features require a subscription.
We've had plenty of hands-on time with the Pod 4 version, but this spring, Eight Sleep revealed its next-gen Pod 5 Core, which now offers advanced monitor cardiovascular and respiratory health monitoring, boasts compatibility with a "hydro-powered Blanket" for a fully enveloping cooling experience and an upgraded adjustable base add-on that features an integrated speaker with surround sound. All of these are add-ons cost extra (the blanket alone will set you back another $1,000), so unless you plan to round out your sleep system with these upgrades, the technology between and Pod 4 and Pod 5 are very similar, with the Pod 4 costing about $300 less.

Cooling sleep products FAQs
What is the best temperature to sleep in?
Sleep experts recommend keeping your room between 60-70 degrees Fahrenheit. Alex Dimitriu, MD, dual board-certified in psychiatry and sleep medicine, tells us that this range has been studied and shown to promote better sleep quality by helping to lower your body temperature, which increases deep sleep and overall sleep quality.
What are the best materials to help sleep cooler?
Dr. Dimitriu highlights that cotton, eucalyptus, and bamboo are excellent for keeping cool as they effectively dissipate heat and enhance ventilation. Nishi Bhopal, MD, a board-certified psychiatrist and sleep specialist, adds that breathable sleepwear made from natural fibers rather than synthetics like polyester is crucial for better temperature regulation. These materials help manage heat and sweat, promoting comfort and minimizing sleep disruptions.
Additionally, sleep products like cooling mattresses, mattress toppers, pillows, sheets, and fans are designed to help maintain a comfortable sleep temperature and reduce nighttime overheating.
How can I make my bedroom cooler?
Dr. Nishi recommends a few strategies that can help maintain optimal sleep temperatures. These include opening windows for better ventilation, using fans to circulate air, and opting for breathable bedding and cooling products. If available, air conditioning is highly effective. Alternatively, look into ways to keep your room cool if you don't have an AC. Dr. Dimitriu adds that in warm climates, combining all of the above can help keep temperatures down.
What are some quick tips to avoid overheating at night?
In addition to using breathable bedding and cooling products to help you sleep better, I recommend that you avoid eating close to bedtime, as it can raise your body temperature and make it harder to fall asleep. Keep electronics out of the bedroom as they emit heat and blue light that can disrupt your sleep cycle. Taking a warm bath or shower before bed can help regulate your body's temperature, making it easier to cool down and relax. Finally, exercising in the morning to reduce evening stimulation and staying hydrated throughout the day is essential to maintain a stable body temperature.
