Sleep in a Cold Room for Comfort and Health

Low Temperatures/High Quality Sleep


Sleeping comfortably can be a tricky thing. What works for one person may not work for another.


For example, a room that feels too cold for one person might feel too hot for another. Or you might be one of those people who gets in bed and feels too hot with a blanket on but then too cold when you take it off.  There’s really no universal magic formula that works for everybody when it comes to getting a good night’s sleep. But whatever your ideal temperature setting is when it comes to bedtime, sleeping in a cold room is known to have its health benefits.


The human body’s internal temperature is usually at its highest in the early afternoon and lowest in the early morning hours. Body temperatures fluctuate throughout the day. But keeping your body temperature cool is known to help you sleep better. When we sleep, our bodies cool off naturally. And if you’ve seen enough sci-fi movies, you know that characters are often “kept on ice” in cryogenic states when they need to be dormant but alive for long periods of time. So it makes sense that in real life the colder your body temperature, the better you sleep.



Super Heat & Air is an air conditioning company, so you know we’re all about keeping things cold! With that in mind, here are some benefits to sleeping in a cold room:


Sleep Faster

We’re no doctors or scientists here but we do know this: sleep is good for you.  And unless sleeping in a furnace is your thing, if your room feels too hot you will probably sweat in bed and not be able to get comfortable. The same could be said about falling asleep in a room that’s freezing: you probably won’t be able to get comfortable. But in a room that’s just cold enough? Ahhhhhh, now that feels good, doesn’t it? In a cold room, your body won’t waste energy trying to regulate its temperature by trying to adjust, which means you can fall asleep fast! So it makes sense that the faster you fall asleep, the more sleep you get, right? (BRILLIANT!)


Sleep Better

Hey, remember that thing you just read about falling asleep fast because your body isn’t trying to regulate its own temperature? Alright! That also means you will not only fall asleep faster, but you’ll also sleep better too! A cold room temperature will help you fall into a deeper, uninterrupted sleep, which means no tossing and turning all night. And consistently sleeping well will also save you money if you rely on prescription drugs or over-the-counter sleeping aids. (You’ll probably save money on coffee and energy drinks too!)


Age Better

Insomniacs are often told to take melatonin to sleep better. That’s because melatonin is a known anti-aging hormone. According to mercola.com, sleeping in temperatures between 60-68 degrees will allow your body to release more melatonin. So it not only helps you sleep better, but helps you age better too. And let’s keep it real here: you know that people who don’t consistently sleep well tend to age horribly. Dark circles and bags under eyes from lack of sleep alone can make a 30-year-old look 50!


Other Benefits

Some studies have shown that sleeping in a cold room can also improve your metabolism and even help prevent diabetes. But again, we’re not doctors or scientists here so we won’t touch on the specifics of that research. (If you really want to know, click here or here).


We are Trane Comfort Specialists, however, which means we’re experts in comfort! So we’ll stick to what we know best … keeping you cool! Here are some ways to keep cool at night:


Get Naked!

No clothes, no heat! The less clothes you sleep in, the less insulation there is on your body. Pretty simple, huh? So if you go to sleep with zero clothes on your body… you get the point!


Fan Up

Become a fan of your fan. Fans are designed to help cool rooms, not people. So use a ceiling or floor fan to circulate air around your room. You’ll love your fan in no time once it helps you fall asleep!


Cuddle Up with a Cold Pillow

Pillow talk. Do you have an extra pillow that you don’t need for your head? Leave one pillow out from under the covers and let it get nice and cold. And when it’s sleepy time, grab that cold pillow and snuggle up with it to help cool your body down. Temperatures at around 65-68 degrees will help cool your room and all of your pillows, including the ones that will go behind your head to help cool it down.


Cuddle Up with a Partner

Snuggle up, buttercup! A cold pillow is nice, but a warm partner is even better! We’ve already established that a cold room is good for you. But keeping comfortable  can be a challenge, especially if you share a room with somebody whose idea of “cold” can vastly differ from yours. Having the body heat of another person in the bed can keep you nice and warm and cozy in a room that feels too cold for you or your partner. And cuddling is also known to relieve stress. So the less stressed you are, the better you sleep! Awww.


Get a Bigger Bed

“We’re going to need a bigger bed!” Not a cuddler but your partner is? This is where the opposite of cuddling comes into play. If you’re one of those people who can’t fall asleep or stay asleep while snuggling with a partner, a bigger bed is a great way to break away from cuddling when you really want to get some Z’s. And a bigger bed is especially helpful when you have a partner who does fall asleep while cuddling but you can’t.

A happy medium can be had when you have a partner who wants to cuddle all night and you don’t. That’s because when you have a bigger bed with more personal space, you can slowly break away once your partner zonks out and sleep on YOUR side of the bed without disrupting each other. And if your definition of cold is different from your partners, keep two separate bed covers of varying thickness to use for your own personal space. 


Let the Right One In

“You put your right foot in, you put your left foot out.” Leaving certain body parts exposed during sleep can help keep you cool. So if you like to stay wrapped up in your blanket all night but it makes you too warm, try sticking one foot outside of the covers to help you stay cool.


Adjust the Thermostat

Take your temperature. When it comes to comfort, the perfect thermostat setting for sleep is subjective. You do want to consider saving money on energy bills by not setting it too low all night. But if you share a home with central air conditioning, not everyone may agree on what the thermostat should be set at. If 65 degrees is too cold for you, try keeping it in the lower 70s for a comfortable cool. And if you find yourself constantly battling with your housemates over what the thermostat setting should be at night, consider a ductless mini-split air conditioning system, which allows for different thermostats in each room.
