SHOCKING: Why Wearing Socks To Bed Makes You Sleep Better The Fascinating Biology Explained Now #socks #sleep #biology #health #shocking

Most people think the secret to better sleep is a cooler room or a better mattress or a white noise machine, but almost nobody thinks about their feet. The research says your feet might be the most powerful lever that you actually have. Here's what I think is happening in your body as you fall asleep. Your core temperature needs to drop by one to two degrees to start initiating sleep. The temperature drop is one of the brain's primary signals that it's time to rest, and that coincides with your body's melatonin release. The colder that your core gets, the faster and more deeply you fall sleep. The way your body cools, it's core, is through a process called distal vasodilation. Blood vessels in your hands and feet widen, heat escapes through your skin, and your internal temperature drops. So the key insight here on all this is warming your feet, actually can help you cool your core, not the other way around. When your feet are cold, your body restricts blood flow to protect your core. So the cooling process stalls, your brain does not receive the sleep signal it's waiting for. Then you lie there awake. A 2018 study published in the Journal of Physiological Anthropology measured exactly what happens when you put socks on before you go to bed. Participants here.
