Do you need to cover your feet when you sleep at night? What is the most scientific and healthy way?

From the perspective of traditional Chinese medicine, because there are many acupoints on the feet, these acupoints are related to the organs in the body, especially the organs in the lower abdomen, and the organs in the body generally work and operate at a temperature slightly higher than the body surface. This is the truth that the soles of the feet go straight to the whole body, so covering the feet is equivalent to helping the organs keep warm and sleep more sweetly. Generally, in summer, if you feel hot, soak in cold water at night or just blow the wind on your feet, you will feel cool all over, but don't blow your feet for a long time, which is easy to catch a cold or cause a cold. In winter, as long as the feet are warm, the body will warm up. This is a fact.
