Do you slip into bed still wearing your socks? You’re not alone — millions do it every night, especially when the temperature drops. But is this cozy habit actually helping your sleep… or quietly harming your health? Here’s what science says.

Surprising Benefits of Sleeping in Socks
Research backed by the American Heart Association shows that keeping your feet warm at night helps your body regulate core temperature faster, allowing you to fall asleep sooner. A 2023 study published in Sleep Medicine found that people who wore socks to bed fell into deep sleep up to 20% faster than those who went barefoot.

Warm feet also dilate blood vessels, improving circulation and reducing night-time leg cramps. For people who suffer from cold feet or Raynaud’s syndrome, socks can be a simple, drug-free way to get better rest.
