Do you sleep better when it's cold outside?
Thursday, 5 November · 2 min read

On cold, dark winter evenings, you may be tempted to climb into bed earlier than usual and snuggle up under a blanket or duvet. But do you actually sleep better when it’s cold outside?

Experts say the answer is yes, but there are a few reasons why.

Room temperature
Bedroom temperature plays a key role in how well you sleep. According to the Sleep Foundation, the ideal temperature for sleeping is 18.3C, or at least somewhere in the range of 15.6C to 19.4C.

While it may be difficult — or expensive — to cool your bedroom to this temperature range during hot summer nights, it may be easier to warm your home during the colder months.

But this also means being careful with the thermostat and not making things too cosy, as having the heating on too high can actually disrupt sleep.

If temperatures get very cold where you live and you need to keep the heating on at night, sleep expert Dr. Neil Stanley recommends setting the thermostat for around 16C.

Body temperature
Your core temperature needs to fall slightly for you to fall and stay asleep. If your home is cooler, which is more likely during colder months, this can help your body cool down and set you up for sleep.

Dr. Stanley says that to get good sleep you need to lose about 1 degree of body temperature.

“Cooler temperatures during the winter can aid sleep," says Dr. Stanley. "But just don’t get too cold.”
