1, solar radiation

When the weather is hot, the sun contains a lot of ultraviolet rays, so people should avoid exposure to the sun. If the skin is exposed to too much sunlight, the ultraviolet rays contained in it will kill a large number of skin cells, which will lead to skin allergy, killing and other symptoms, especially the facial skin is not easy to cover, and it is easy to choose itching symptoms. Therefore, when the weather is hot and the sun is toxic, we must avoid direct sunlight, do a good job of sun protection and try not to be active in the sun.

2. Salt stimulation

The human body will sweat a lot in a hot environment, and sweat will take away a lot of salt when it consumes human water. If the sweat dries after sweating a lot, it is easy to leave white powder where there was sweat before. These are crystalline salts, which will have a great impact on the skin, absorb the moisture of skin cells, destroy the horny structure of the skin, make the skin rough, and stimulate the skin nerves to itch. If it is itchy caused by sweating, be sure to wash the sweat off in time to avoid causing great harm to the skin.

3. Bacterial infection

In high temperature environment, the immunity of human skin is reduced. If the skin is not clean enough, it is easy to be infected by bacteria, so there will be many diseases such as inflammation and skin diseases, so it is easy to have symptoms of itchy skin. In this case, when the weather is hot, we must pay attention to the cleanliness of the skin and try not to touch contaminated things to avoid being infected. Once an infection occurs, you need to go to the hospital as soon as possible to avoid the deterioration of your condition.
