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.”

Benefits Of Cold Sleeping

There are many reasons that sleeping in a cooler environment can benefit your health. Here are to cool down tonight.

1. Fall Asleep More Quickly

It’s simple math, really. Provide an environment for your body to fall asleep more comfortably, and it will, in a faster manner. If it’s too hot or too cold, your body will waste energy trying to regulate, and leave you tossing and turning all night.

2. Get A Better Night’s Sleep

When your body isn’t trying to regulate itself, you’ll fall into a deeper, more restorative sleep. in Australia has also proven that sleeping in cooler environments can help decrease certain types of insomnia.

3. Look More Youthful

It’s been shown that sleeping in temperatures between 60-68 degrees will allow your body to release more melatonin, one of our best anti-aging hormones.

4. Decrease Your Risk For Certain Metabolic Diseases

it was determined that sleeping in a 66-degree room not only burned more calories while awake, but the amount of “brown fat” (or good fat) in the body increased. Brown fat allows your body to burn calories, not store them.

Together, this could help lower the risk for metabolic diseases like diabetes over time.
