What’s the Best Temperature for Sleeping?
Recommending a specific range is difficult, Downey and Heller say, because what is comfortable for one person isn’t for another (explaining how Roy’s wife slept blissfully in the chilly 60-degree room). While a typical recommendation is to keep the room between 65 and 72 degrees Fahrenheit, Heller advises setting the temperature at a comfortable level, whatever that means to the sleeper.
Roy plans to keep a close eye on the thermostat, even if the heat bills are a bit higher.
There are other strategies for creating ideal sleeping conditions, too. Experts from the American Academy of Sleep Medicine, for instance, advise thinking of a bedroom as a cave: It should cool, quiet, and dark. (Bats follow this logic and are champion sleepers, getting in 16 hours a day.) Be wary of memory foam pillows, which feel good because they conform closely to your body shape -- but may make you too hot. And put socks on your feet, as cold feet, in particular, can be very disruptive to sleep.
