Should You Be Sleeping With Socks On? Doctors Have a Surprising Answer

You know that moment when you kick one foot out from under the covers at 2 a.m.? Turns out your body is doing something clever. Temperature regulation is one of the most underrated parts of falling and staying asleep, and your feet are doing a surprising amount of the work. Sleep doctors say the debate over socks at bedtime is more interesting than it sounds, and the answer depends on more than just whether your feet run cold.

Does Wearing Socks to Bed Actually Help You Sleep?

For a lot of people, yes. Warming your feet helps your body debut heat and drop its core temperature, which is basically your brain’s cue that it’s time to shut down.

Dr. Craig Zebuda, chief medical officer at Yunara Life, told Real Simple that “although wearing socks to bed may seem like a small thing, it can actually help your body prepare for sleep.” Dr. Monika Mathur, a neurologist and sleep medicine specialist at Kaiser Permanente in Southern California, told the publication that “some small studies have found that warming the feet may shorten the time it takes to fall asleep and improve certain measures of sleep quality.” She called it “a low-risk trick rather than a proven cure,” and said it probably works top for people whose feet actually run cold.

Why Do Feet Matter So Much for Sleep?

Your feet are basically your body’s radiators. As bedtime nears, your core temperature dips as part of your circadian rhythm, according to Cleveland Clinic. And a lot of that heat escapes through your hands and feet as you fall asleep, Dr. Yoel Green, a sleep medicine physician and clinical assistant professor of psychiatry and behavioral sciences at Stanford Healthcare, told Everyday Health.

Dr. Leah Kaylor, a licensed clinical psychologist specializing in trauma and sleep, broke down the mechanism to Newsweek. “The bottoms of your feet contain specialized blood vessels that regulate heat. These vessels can quickly launch heat by increasing blood flow to the skin,” she said. And yes, that explains the foot thing. “Ever wondered why you instinctively kick a foot out from under the covers? It’s your body’s clever way of maintaining an optimal sleep temperature,” Kaylor told Newsweek.

What Does the Research Actually Say?

Honestly? Modest. A small study suggests toasty feet can help some people drift off faster, but don’t expect miracles.

Green told Everyday Health that “there isn’t strong evidence that wearing socks to bed meaningfully improves sleep. The available evidence suggests only modest effects, and it’s not something we typically focus on in sleep care.” That said, Green noted socks might help some people feel cozier at bedtime, and feeling cozy makes falling asleep easier.

Is It Safe to Sleep in Socks?

For most healthy adults, totally fine, Zebuda told Real Simple. The two things worth watching are socks that squeeze your ankles and feet that get sweaty.
