What should I do if I itch in summer?

With the coming of summer, everyone's skin becomes sensitive because of the hot weather. Sometimes, especially in the afternoon or at night, I suddenly feel itchy and want to scratch. What is the reason?

1, hot weather

High temperature weather in summer and direct sunlight make the skin lack a lot of water after sunburn, and skin allergy leads to redness and itching. Or when the weather is hot, you get prickly heat and your skin itches, so you want to scratch it. In addition, hot weather is easy to get angry. The body is short of water after getting angry. At this time, it is necessary to replenish water in time, otherwise it will also lead to itchy skin.

2. Sweat a lot

In summer, the weather is hot and the skin sweats a lot. If it is not cleaned in time, the sweat stays on the surface of the skin and the skin is easy to itch. After sweating, sweat evaporates slowly and often stays on the skin for a long time. At this time, protein, inorganic salts and other components in sweat are decomposed by bacteria to produce metabolites, which have a certain stimulating effect on the skin. In addition, wearing chemical fiber clothes, using too alkaline soap, or touching some irritating chemicals may cause itchy skin.

3, skin allergies

In summer, the skin is exposed to a large area, which is easily stimulated by the outside world and exposed to allergens, leading to skin allergies. For example, sleeping on a mat is prone to mite dermatitis symptoms, and eating certain foods can also cause dermatitis symptoms. Sunshine in summer can also make people suffer from photosensitive dermatitis.
