What's the Best Temperature for Sleep? New Survey Says 67°F
Some of us pile on the blankets at night, while others would happily sleep with the window open in the middle of winter. But, when it comes to the best temperature for sleep, Americans have landed surprisingly close to the same number.
A new nationwide survey found that the average preferred sleep temperature in the U.S. is 67°F. Even better, that number falls right within the range sleep experts often recommend for a comfortable night's rest.
Americans Prefer Their Bedrooms at 67°F
Bear Mattress surveyed 2,119 adults in all 50 states in February 2026 to learn more about Americans' sleeping habits. When asked about their preferred bedroom temperature, the national average came in at a pleasantly chilly 67°F.
Of course, not everyone agrees. Massachusetts residents like things the coolest, reporting an average preferred temperature of 63.2°F.
Conversely, Hawaii landed at the opposite end of the thermostat, with residents preferring an average of 69.5°F.
Sleep Experts Like a Cool Bedroom, Too
As it turns out, Americans may be onto something. Cleveland Clinic sleep specialist Dr. Brian Chen says a bedroom temperature between 60°F and 67°F is best for sleep.
Our core body temperature naturally drops as part of our circadian rhythm when we sleep, and an overly warm room can interfere with that process. Meanwhile, the Sleep Foundation made a similar recommendation, putting the ideal sleep temperature at about 65°F to 68°F for most adults.
So, while 67°F isn't a magic number, it lands right inside the sweet spot.
Your Perfect Temperature May Be Different
Before you march over to the thermostat and dial it to 67°F, there's a little room for personal preference.
For example, age can make a difference. One study involving adults 65 and older found that sleep quality was best when nighttime bedroom temperatures ranged from 68°F to 77°F, with considerable variation from one person to another.
That means the perfect bedroom temperature is ultimately the one that helps you fall asleep, stay asleep, and wake up feeling rested.
You Can Cool Things Down Without Cranking the AC
Not everyone wants to run the air conditioner all night just to reach the best temperature for sleep. A fan and lightweight, breathable bedding can keep things comfortable when the room feels a little warm.
Cleveland Clinic also recommends adjusting the thermostat before you go to bed, rather than waiting until you're already tossing and turning.
Closing your curtains or blinds on hot days can also help prevent the heat from building up in the bedroom before bedtime.
Tonight, 67°F Might Be Worth a Try
There isn’t one ideal sleep temperature that works for every person, every season, and every bedroom. Still, it's interesting that Americans’ preferred 67°F lines up well with expert recommendations.
So if you've been flipping your pillow to the cool side all night or kicking the covers onto the floor, try lowering the thermostat a couple of degrees tonight.
You might discover that a slightly cooler bedroom is one of the simplest ways to sleep better.
