Science Says Sleeping In A Cold Room Is Better For Your Health

Have you given much thought to the temperature at which you fall asleep or you need treatment as coricidin high? I haven’t. Turning on a fan or opening/closing windows is always a game-time decision for me, right when I’m about to hit the hay.

My feet and hands are always chilly, so I prefer to hop in bed when the sheets aren’t ice cold. But if it’s too warm (especially with my furry baby animal heaters,) I’ll wake up in the middle of the night hot and uncomfortable.

So, where’s the middle ground? Is there an optimal sleeping temperature? Science says yes.

medical director at Charlottesville Neurology and Sleep Medicine, says your bedroom should be between 60 to 67 degrees Fahrenheit for optimal sleep. Temperatures above 75 degrees and below 54 degrees can disrupt sleep.


Over a 24-hour period, our body temperatures naturally peak and decline. Our internal temperature is usually at its highest in the early afternoon and lowest around 5 a.m. When we fall asleep, our bodies naturally cool off. Helping your body get to that lower temperature faster can encourage deeper sleep.

Cameron Van den Heuvel, of the UniSA’s Centre for Sleep Research, 

“About one to one and a half hours before falling asleep, the body starts to lose heat from its central core and that brings on increased feelings of tiredness in normal healthy adults. These physiological changes happen well before going to bed and maybe occurring before people realize them.”
