Too Hot? Too Cold? How Body Temperature Affects Sleep

Updated: Sep 25

Tips to help you reach a comfortable core body temperature at night.

Are you a hot or cold sleeper? Chances are you already know the answer to this question—and that the difference between the two can be dramatic. Even if a hot sleeper and a cold sleeper have the exact same mattress, pillows, and sheets, one may wake up drenched in sweat while the other may wake up shivering.


Getting too hot or too cold at night can disturb your sleep and lead to feeling terrible in the morning. And as the seasons are changing, maintaining a comfortable body temperature can be increasingly difficult. That is why we are here with a few handy tips. 


If you find yourself waking up sweating or shivering at night, check out these ways to maintain a comfortable core body temperature:


Hot Sleepers

Are you tossing and turning at night because you feel too hot? Throwing sheets, blankets, and pets off yourself to try and stay cool? You may be a hot sleeper.


Why the constant waking up? The reason is because you feel uncomfortably hot AND your body is not maintaining the cooler temperatures needed to help the release of sleep-inducing melatonin. Here is what you can do to help:

  • If you are a hot sleeper, try to keep your bedroom at 60 to 67 degrees fahrenheit at night. Cooler room temperatures are ideal, but we get that they may not be practical for everyone. Lacking air conditioning, needing to keep utility bills economical, and having a partner with different preferences can all interfere. Keep reading.

  • Take a warm shower or bath before bedtime. As you cool down after a warm shower, it signals to your body that it is time to wind down, making it easier to fall asleep.

  • Keep your room cool throughout the day. Use blackout curtains or blinds to prevent the sun from excessively warming up your bedroom in the first place.

Keep in mind that while feeling too warm can be related to your sleep environment, it can also be related to a medical condition. Don’t hesitate to ask for advice from your medical practitioner if you are sleeping too hot.

Cold Sleepers

Waking up shivering with goosebumps on your arms? Fingers and toes freezing? You may be a cold sleeper. 


Whether you have a heightened sensitivity to the cold or you live in a cold place, bumping up your body temperature can be important to achieving a good night’s sleep. Try this:

  • Wear socks in bed. A little extra layering goes a long way. Keeping your feet warm is an important part of feeling warm all over. We recommend a fuzzy and cuddly pair of socks—potentially with polka dots.

  • Pick a good blanket. Heavy and thick blankets will hold in more heat around you. Upgrade to a weighted blanket to stay extra cozy and prevent tossing and turning.


Dual-Sided Mattress Topper for Hot and Cold Sleepers

Our Renew Gel Memory Foam Topper features two sleeping surfaces: a “summer” side with moisture-wicking Tencel fabric and a fluffy duvet “winter” side. The cool response Tencelsurface gets cool to the touch for hot sleepers when they break a sweat. The fluffy duvet surface creates a little extra cozy warmth for cold sleepers. Pick the side that fits your preferences, or flip it over to match the season outside. Either way, you get 2.5 inches of softening gel foam to refresh your existing mattress. 


Can a Mattress Help Hot or Cold Sleepers?

If you want to take a significant step toward maintaining a comfortable body temperature at night, consider purchasing a temperature-regulating mattress.

Best Mattress for Hot Sleepers

When picking out a mattress as a hot sleeper, prioritize qualities like breathability and adaptability. Pocketed coil hybrid mattresses typically offer superior breathability. However, modern memory foam mattresses don’t always trap heat like they used to. Our memory foam mattresses replace thick, dense top foam layers with breathable, gel-infused foams. As the icing on the cake, a number of Bed Boss mattresses feature a component of excellent temperature adaptability: moisture-wicking covers that instantly absorb and dry sweat.

Best Mattress for Cold Sleepers

If you are a cold sleeper, consider a traditional memory foam mattress that gently hugs you for an extra cozy and snuggly sensation. A mattress that holds you and conforms to your curves will help you to comfortably retain heat. Keep in mind that gel-infused foams will not chill the mattress, but rather respond only to excessive heat buildup.

Why to Choose The Bed Boss

All of the mattresses in The Bed Boss collection incorporate materials designed to help you maintain a comfortable core body temperature. For example, our hybrid and memory foam mattresses have a gel-infused top layer that pulls excess heat away from your body.
