Why does the skin sometimes itch when running in cold weather?

I believe that the season that many friends who like sports dislike most is winter, not only because of the cold, but also because of the strong wind. Many people who run in cold weather will find that when they sweat, their skin will itch. This makes many people who like running feel very uncomfortable, but they can't say why.

This is because pores are closed in cold weather. Once you start running, your whole body's blood circulation will accelerate, your body will sweat, and your skin will be stimulated by alternating cold and hot, so it will itch. In winter, the weather is very dry, and many people are not used to applying moisturizer after bathing, which makes their skin very sensitive and fragile. We usually wear too much, and our skin basically can't breathe normally. Suddenly running and sweating, the pores will inevitably open. At this time, the skin is dehydrated and drier, so it will itch.

In winter, because of the cold weather, people seldom rely on sweating to detoxify. But once you run, the toxins in your body will still be eliminated from your pores with sweat. At this time, the sweat is very difficult to dry, and it stays on the skin and clothes, so the skin is naturally itchy. You can't wear too thick clothes when you run, otherwise your clothes will be soaked and cling to your body when you sweat, and your body's heat will not be emitted, and your skin will naturally feel uncomfortable, which will definitely itch. Also, because of the lack of water, people don't drink much water in winter, and they are short of water both inside and outside. Suddenly running and sweating, the body is more dehydrated, and the skin is dry and itchy. In addition, if you run indoors in winter, you can avoid this problem. Because you don't have to wear thick clothes indoors, and your skin will not be stimulated by cold air. Skin, which is already short of water, will definitely feel uncomfortable when it is hot and cold outdoors. In addition, if you can apply some moisturizing cream or moisturizing oil in time in winter, you can also avoid itchy skin during exercise. We must drink more water and eat more fruits and vegetables in winter to keep the water in and out of the body balanced, so that we can stay away from itching.
