How does the back skin itch in winter return a responsibility?

Some people often feel itchy every winter, from the inner thigh, front and back of the calf, shoulder and back to unbearable itching all over the body. This is medically called "winter dermatitis". The main cause of winter dermatitis is dry skin. Due to the cold weather in winter, the metabolism in the human body is slow and sweating is relatively small, which cannot nourish the skin. Coupled with the dry and windy weather, the skin is dry and rough, which is easy to cause itching. Nowadays, many people are used to taking a bath every day to wash off the already thin oil, which is more likely to cause itchy skin. Chinese medicine also believes that winter dermatitis mostly belongs to blood deficiency and blood dryness. Blood deficiency leads to wind, then the skin itches; When the blood dries up, the skin is chapped, red and painful. To prevent this disease, it is necessary to keep the indoor temperature and humidity appropriate. Eat fat properly in the diet, eat less or no hot and sour food, and try not to eat easy-to-eat food. Control the number of baths. Don't burn your skin with overheated water when taking a bath. After taking a shower, apply lotion to places that are particularly prone to dryness and itching. Underwear should not be too tight. Soft and warm cotton products are most suitable. People with blood deficiency can take some drugs to nourish blood, dispel wind and relieve itching. Never scratch when you itch, otherwise the more you scratch, the more itchy you are, and once you scratch your skin, it is easy to cause infection.
