What is the cause of Chun Xue?
Keep warm when it snows in spring.
Some people think that it's cold in snowy weather, so we should wear more and thicker clothes, and the more we wear, the warmer we will be. In fact, according to the introduction of health experts, this understanding is wrong, because the warmth of clothes is related to the thickness of the air layer inside clothes. When you put on a piece of clothing, the thickness of the air layer increases and the warmth is enhanced. However, when the total thickness of the air layer exceeds 15 mm, the air convection in the clothes increases obviously, but the warmth retention decreases.
Physiologically speaking, if people wear too many thick clothes, skin blood vessels will expand due to high fever, which will increase heat dissipation and reduce the body's adaptability to external temperature changes, so don't wear too thick clothes on snowy days. In addition, keeping warm in snowy days should start from the feet, all diseases should start from the feet, and all cold should start from the legs. Once the feet are cold, it will have a certain impact on the whole body.
