They’re quite the dream team, and their sock-wearing sleep routine is one that many others share in order to get their restful Zzz’s. But why?
Temperature regulation is one of many factors that contribute to a full night's rest. Your circadian rhythm, also known as the sleep-wake cycle, affects your core body temperature by rising during the day to keep you alert and dropping in the evening to make you sleepy.
Typically, the body drops 1-2 degrees when you’re about to fall asleep. But warming up your feet with socks causes vasodilation–dilation of the blood vessels–which increases blood flow to the feet and heat loss through the skin. Therefore, this lowering in core body temperature signals to the brain that it’s time to hit the hay.
The ideal bedroom temperature for a good snooze? Between 18-21 degrees Celsius. This will help send the right signals to your brain that it's time to drop your body temperature so you can sleep.
Not one for wearing socks in bed? Try layering blankets at the foot of the bed or use a hot water bottle. A warm bath before bed can also drop your body temperature.
Beyond helping people sink into deep slumber, wearing socks to bed offers other benefits:
Reduced symptoms of Raynaud’s disease:
Raynaud’s is a condition, typically affecting the skin around the toes and fingers, where individuals lose circulation and experience throbbing and/or swelling.
Prevents hot flashes:
Hot flashes–caused by hormonal fluctuations–affect the body’s core temperature, and wearing socks can alleviate this.
