Some people believe wearing socks to bed is vital for a good night’s rest, while others wouldn’t dream of it. New research indicates wearing socks when you slumber can help your sleep and health.

Sleeping with cold feet causes less blood to circulate, which can lead to restless nights. Wearing socks also helps regulate your body temperature.

Nighttime sock-wearing is particularly helpful for women experiencing hormonal changes during menopause. Controlling core body temperature helps combat hormonal fluctuations that lead to hot flashes, which can disrupt sleep.

Sock wearing can also decrease your risk of Raynaud’s [ray-NOSE] disease, which causes some areas of your body, such as fingers and toes, to feel numb or cold. When paired with moisturizer, it can also help soothe dry feet and cracked heels.

When searching for the perfect bedtime sock, look for breathable materials such as merino wool or cashmere. These will help your body regulate its temperature without overheating. Fit is also important. Socks that are too tight can cut off your circulation. Compression socks should never be worn to bed unless prescribed by your doctor. To ensure good hygiene, select a clean pair before bed and change them in the morning.

If wearing socks to bed is not for you, many of the same benefits can be achieved with a warm foot bath before you go to sleep or placing a blanket over the foot of the bed. In addition, experts recommend keeping your bedroom temperature between 60 and 67 degrees. These experts, of course, aren’t paying your power bill.
