20 Natural Sleep-Inducing Habits That Help You Gently Drift Into Dreamland
16. Keep Your Feet Warm

It may sound odd, but cold feet can keep you awake. When your feet are warm, blood vessels dilate, which helps lower your core body temperature—a signal to your brain that it’s time to sleep. Wearing socks to bed or using a hot water bottle at your feet can help trigger this process. Studies show that warm feet are linked to faster sleep onset. Choose breathable, loose-fitting socks made from natural fibers for comfort. It’s a small adjustment with surprisingly big results, especially for those who tend to toss and turn.
