Sleeping In A Cold Room Is Better For You, Proved By Science

The temperature in your bedroom can greatly affect how well you sleep. Turning on a fan or opening/closing windows are great ways to keep your bedroom temperature cool on a hot summer day…but if your feet and hands are always chilly, than it’s not so comfortable to slip into ice cold sheets. However, if your bed is too warm, than chances are you’ll be up all night tossing and turning.

So where’s the middle ground?

Is there an optimal sleeping temperature?

Science says yes!

Dr. Christopher Winter, Medical Director at Charlottesville Neurology & 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. Why? 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 5am. When we fall asleep, our bodies naturally cool off. Helping keep your body get to that lower temperature faster can encourage deeper sleep. Dr Cameron Van den Heuvel, of the UniSA’s Centre for Sleep Research says, “About one to one and a half hours before falling sleep, 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 may be occurring before people realize them.”
