Those who like to drop their thermostat to cool at night have the right idea, according to research.
Dr. Christopher Winter, director of Charlottesville Neurology & Sleep Medicine in Charlottesville, Virginia, and author of “The Sleep Solution: Why Your Sleep Is Broken and How to Fix It,” says the ideal temperature for sleep is cool between 60 F and 67 F. Anything above 75 F or below 54 F can disrupt sleep, reports the website Simplemost.
The reason is simple: Your body cools when it’s time for bed. As it cools, it brings feelings of tiredness. Being in a cool room will bring about those changes more quickly. And if your body isn’t trying to regulate itself in a too hot or too cold room, you will sleep better.
Sleeping in a cool room has other benefits, as well. Science shows it can decrease insomnia, release more melatonin (which also acts as an anti-aging hormone) and burn more calories, lowering the risk of metabolic diseases like diabetes, reports Simplemost.
