How does old person have a fever blush to return a responsibility?

First: I don't know if you've ever had such an experience. When you enter the room from the outside in winter, your face will turn red. When you are exposed to the sun in summer, your face will turn red, just like you are shy when you meet someone you like.

Second: peripheral blood circulation is better, some people belong to the facial peripheral blood circulation is better, people as long as a little activity will cause blushing phenomenon. When the face is heated, it causes the continuous expansion of capillaries and the acceleration of peripheral blood circulation, which can be seen on the face. For this kind of people, we should strengthen physical exercise, enhance the resistance of the skin, and relieve the condition that the skin is often red.

Third: the temperature difference is too large. According to the principle of heat expansion and cold contraction in physics, heat will expand the blood vessels of human skin, and cold will contract the blood vessels of human skin. During outdoor activities in winter, blood vessels contract rapidly when encountering cold air. Once the indoor temperature rises, blood vessels begin to expand slowly, which will form the blushing phenomenon we see. But frequent shuttling back and forth in extremely cold and hot places will make the capillaries in the skin lose their original elasticity in repeated contraction and expansion. Generally, in the early stage, facial flushing can recover immediately; Once the capillary is repeatedly expanded for a long time, it will make the capillary lose its elasticity, and even can not recover after the capillary, resulting in the face has been red, and the phenomenon of flaky red appears.

matters needing attention

In winter, we should keep our face warm to prevent skin from losing elasticity due to sharp temperature changes. Do a good job in the dry room face water work, try to wash your face with warm water, avoid cold water on the face caused by stimulation. In the summer should do a good job in the face of sunscreen work, to avoid the face skin and direct radiation by the sun, so that ultraviolet damage to the skin, leading to face redness.
