What is the cause of Chun Xue?

It snows in spring because of the influence of cold air. Cold air and warm and humid air meet in spring, and low temperature in spring will lead to snow in spring. Snow in spring is actually a manifestation of the cold in spring, which has a great influence on crops and fruits. Generally speaking, it seldom snows in spring, and even if it snows, it won't rain heavily.

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.
