Sleeping in a Room With This Temperature Could Boost Your Metabolism
Believe it or not, the room temperature while you sleep could affect your metabolism and ability to fall asleep easier.
In the winter months, we look forward to going to bed, slipping under the warm covers, and falling into a deep slumber. While a warm and cozy room is inviting, some science suggests that keeping bedrooms on the cooler side could help improve health, from burning more calories to getting a better night’s sleep.

So, how cold should you go? Around 66 degrees Fahrenheit may be the ideal temperature. A 2014 study published in the journalย Diabetes foundย men who slept in rooms cooled to 66 degrees for a month increased their levels of calorie-burning brown fat by 42 percent and their ability to metabolize fat by 10 percent. (The men slept with just bed sheets.) These men also showed improvement in their insulin sensitivity, potentially lessening their risks of developing type 2 diabetes. While the study’s sample size was smallโfive healthy men with an average age of 21โit suggests some potential in terms of type 2 diabetes prevention.
Researchers believe that in a cool space, our bodies have to work harder to raise ourย core temperature to 98.6 degreesโthe “normal” body temperature, although this varies from person to person.ย More work meansย more calories torched.ย โLowering the room temperature before sleep turns on your bodyโs thermoregulatory functions to keepย you warm,โ explains Bridgette Agee, RN, a registered nurse and the Bariatric Program manager at the Marina Weight Loss Center at Cedars-Sinai Marina Del Rey Hospital in Marina Del Rey, California. โThe action also activates brown fat cells that require energy from the white fat stores, and this borrowing of sorts helps to decrease the amount of white fat or โbody fatโย in the body.โ She adds that rest is essential during this process to rejuvenate or reset your metabolism.

You may also be able toย fall asleep easier in a cooler room, according to the National Sleep Foundation.ย A study published in theย Journal of Physiological Anthropologyย found snoozing in warmer temperatures can increase wakefulness and decrease both slow-wave and REM sleep. In addition, humid heat increases the thermal load during sleep, impacting sleep stages and thermoregulation.
A good night of sleepย can also lead to a host of other health benefits, such asย protecting your brain from Alzheimerโs disease, improving immune-system function, boosting your productivity, and fighting aging. The Centers for Disease Control and Prevention notes that sleep can also can help to prevent or control a number of chronic illnesses, including type 2 diabetes, cardiovascular disease, obesity, and depression. And, of course, it can also improve your mood and make you feel better.
The bottom line: A cool(er) room may be optimal not just for a good night’s sleep, but your overall health.
