Why does it itch all over when it is hot? What should I do if the whole body itches in hot weather?

When the weather is hot, our bodies are prone to problems, especially the skin, which is prone to uncomfortable symptoms such as acne, rash, redness and itching. Why does it itch all over on a hot day? This is mainly related to human metabolism. Let's take a closer look at the details and solutions of itching all over the body in hot weather.

1, sunshine reason

When the weather is hot, the sun is very poisonous and the ultraviolet radiation inside is also very strong. If the morning is long in this case, it is easy to have health problems. Due to the influence of ultraviolet rays from the sun, skin cells will be damaged, and then the skin will have adverse reactions such as redness, fever, edema and pain. If the symptoms are mild, the human body will have itching symptoms when repairing damaged skin. In this case, you must do a good job of sun protection when you are active in direct sunlight to avoid harm to your body.

2, allergic reaction

When the ambient temperature is high, the human body is prone to a lot of sweating symptoms. When sweat is secreted, it will bring out a lot of mineral components and metabolic toxins in the human body. When sweat evaporates, these salts will irritate the skin and absorb the moisture in skin cells, which will easily lead to allergic reactions of the skin, thus causing skin pruritus. In this case, it is necessary to stay in a cool environment as much as possible, reduce sweat secretion, and wash it in time when sweating heavily to avoid adverse effects on health. Eat more fruits and vegetables in the diet, and eat less foods rich in artificial additives to reduce toxin metabolism, which is also good for skin health.

3, skin lesions

When the weather is hot, the pores on the surface of human skin are in an expanding state, and the immunity is relatively low. The human body secretes a lot of sweat, which will attach to harmful substances such as dust and bacteria in the air. After a large amount of accumulation on the skin surface, the skin will be affected by bacteria and become diseased, so there will be symptoms of itchy skin. In this case, it should be cleaned in time after sweating, and stains such as sweat should not be attached to the skin for a long time.
