Is it warm to sleep with clothes on or without clothes?

The purpose of wearing clothes is to keep the heat in the clothes, and it will be cold if you feel the outside air in the uncovered parts. Sleeping without clothes, just like a quilt is clothes, the whole body is wrapped. Without the influence of tiny folds of clothes on the body, the body is easy to relax, thus ensuring smoother blood and more active metabolism. This can not only help people fall asleep quickly, but also effectively improve the cold hands and feet of some people and improve the circulation of nerve endings. Naked sleep takes away the pain. In addition to the cold in the early stage, a large amount of heat emitted by the body will form a closed and warm space, and there will be no temperature difference in different parts, so it is also the reason why naked sleep feels cold, and there is no constraint.
