What are the causes of allergic skin itching?

Human skin is very fragile, so various skin diseases arise, and pruritus is a very common skin disease. There are many causes of pruritus, and various factors may cause pruritus. So what are the common causes of skin itching?

Climate factors:

The cause of skin itching is closely related to climate. As the climate changes, people's skin will also undergo different changes. Dryness and wrinkling are very common, which are the causes of itching. In addition, changes in temperature are also a cause of skin itching. The skin will also change accordingly with changes in temperature. Especially in summer and winter, the temperature difference between indoors and outdoors is relatively large. If the temperature fluctuates frequently, it will cause skin itching.

Dietary factors:

Eating is something that everyone must do every day. You may think that eating is very simple, but if the diet is unreasonable, it will also cause skin itching. For example, excessive drinking, drinking strong tea, eating shrimps and crabs, spicy food, etc., these diets are common factors that cause skin itching. Once skin itching occurs, it is very difficult to stop, so everyone will scratch it, and some people even need to use instruments to scratch until they feel pain. This can easily lead to more serious damage to the skin, and if the wound is not taken care of, it is likely to cause infection, making you feel even more painful. Therefore, in daily life, we should pay attention to avoid these unfavorable dietary factors as much as possible, and the diet should be light.

Quality of underwear:

Underwear is worn close to the skin so the quality must be good. If the quality of the underwear is very poor, it will also cause skin itching. In addition to rough underwear, there are also some underwear made of fur, which can also cause skin itching. Especially for some elderly people, due to the atrophy of their skin and its accessory organs, such as sebaceous glands and sweat glands, the water content in the skin will decrease significantly, and the subcutaneous fat will also become significantly thinner. In this case, the skin becomes very dry. Therefore, the elderly should try to wear pure cotton underwear in order to prevent itching caused by excessive dryness of the skin. At the same time, pure cotton fabrics can also avoid irritation to the skin.
