Many people have a habit of sleeping with one leg sticking out from under the blanket. It may seem like a random position, but experts say there is actually a simple reason behind it.
During sleep, the body works to regulate its temperature. If you become too warm under heavy blankets, your brain looks for ways to cool down.
Sticking one leg out helps release heat quickly. Because the feet and legs contain many blood vessels close to the skin, they are effective at helping the body adjust its temperature.
Sleep researchers say this small change can make it easier for the body to relax and fall into deeper sleep. Cooling the body slightly signals the brain that it is time to rest.
Some people do this without even realizing it. The body naturally shifts positions throughout the night to maintain comfort and proper temperature.
The habit is especially common during warmer months or when thick blankets trap too much heat.
So if you often wake up with one leg outside the blanket, it is simply your body’s way of staying comfortable while you sleep.
