If you’re struggling with sleep issues, consider keeping your socks on, says Daniel Amen, M.D., a brain disorder specialist and coauthor of The Brain Warrior’s Way.
A thin pair of gloves may help, too. “Researchers have found that warm hands and feet were the best predictor of rapid sleep onset,” he says. According to the National Sleep Foundation, warming up your feet or hands causes a beneficial dilation of your blood vessels, which is a signal to your brain that it’s bedtime. Once the blood vessels are open in your hands and feet, heat redistributes to the rest of your body to get it prepped for sleeping. If you get too warm in the middle of the night and have to ditch your socks, just be sure to fling them off without glancing at the clock, Dr. Amen advises. “Checking the time can make you feel anxious,” he says, and that can keep you from falling back asleep easily.
