Many of you are already aware of the “one leg out” sleeping position, in which one leg is hooked over the covers, while the other leg remains nestled under them. This clever approach to cooling the body down during sleep actually has a scientific basis.
The body prepares for sleep by dropping its core temperature, and in the deepest stages of sleep, body temperature actually dips a couple of degrees below normal. This is part of the natural physiology of slumber. Even some of the pre-bedtime rituals which some people adopt, such as taking a warm bath or drinking a cup of hot herbal tea, cause the body temperature to cool rapidly, priming it for sleep.
When we uncover our feet but keep the rest of our bodies snug under the bedclothes, or we swing one leg over the covers, we enable the blood vessels of the feet to dissipate body heat and keep us cool, which further supports restful sleep. Besides, who enjoys sweating while trying to sleep?
Some scientists even recommend keeping feet uncovered while sleeping at night, especially if you are sleeping next to a partner or pets (those of you who have pets know that they often sleep ON you). Another tip is to keep your bedroom temperature between 60 and 68 degrees, so if you are in the habit of cranking up the heat to keep your home warm and cozy, you might want to drop the thermostat setting at night while you sleep.
