You probably know what a challenge it can be to stay asleep during hot nights. You’re sweating, your skin feels sticky, and eventually, you wake up groggy.
The thing is, according to science,your body has been designed to sleep in a cooler environment, and tweaking your thermostat has plenty of benefits for your sleep. Five, to be precise.
Here are 5 health benefits of sleeping in a cool room.
1 - Deeper Sleep
Sleeping in a colder room can improve your sleep quality and even help you combat insomnia episodes. Scientists link this to the fact that our body temperature naturally drops at night. Hence, the metabolism rate slows down, and we spend less energy during sleep.
The most pronounced drop in body temperature happens when you enter REM sleep. It’s the stage of deep sleep during which you typically see dreams. Cellular repair and memory consolidation occur during REM sleep too, so it’s a very important stage and sleeping at cooler temperatures may promote the transition to it.
Now, a word about people with insomnia.
Experts assure that both late-evening insomnia and early morning awakenings are linked to disruptions in the body temperature rhythm. So, adjusting your thermostat somewhere between 60 and 68F (or 15-19°C) may help your body lower its temperature faster and hence, shorten your sleep onset and increase the percentage of deep sleep throughout the night.
2 - Hormonal Readjustment

3 - Weight Loss
Those who are trying to slim down, cheers ! Sleeping in a cold room can help you lose weight !
A 2014 study published in the Diabetes Journal reported that a group of men who slept in a cooler environment (18°C compared to 23°C in the control group) had increased amounts of brown fat.
Brown fat is considered "good" fat. Your body can use it as an energy source, unlike white fat, which is stored in fat tissue and can lead to diabetes.
Although the study was conducted on healthy individuals, scientists believe that the results can be used in creating a treatment for prediabetes and helping obese people reduce weight.
4 - Anti-Aging Properties
