What causes itchy skin when running?

Running to lose weight is the first choice for many people's fitness. Energy replenishment before running, whether you like morning running, night running or long-distance running, many people are in a hungry state before running. It is also very common to have itchy skin while running, so we should pay attention to the corresponding problems before, during and after running, and we should pay attention to prevention. So what are the causes?

You may not have exercised for a long time and just started running. Your leg muscles need to provide you with the power to run, and the muscles will produce heat. But when the muscles are tense and irritate the skin, it may feel itchy, like ants crawling on it.

Insufficient warm-up. When exercising, such as running, blood circulation speeds up and the body sweats. The subcutaneous capillaries in some parts of the body are narrow and the skin pores are tightened. The capillaries cannot withstand the pressure caused by the sudden acceleration of blood, and the pores cannot eliminate sweat, which causes an itchy feeling.

Because it has a certain incubation period, symptoms often appear several days after the first contact.

Diet causes skin allergies. In the hot summer, people often eat fish, shrimp, and crabs. Seafood is a type of food that causes skin allergies, so improper diet often causes people to experience symptoms of itchy skin in the summer.

Sweat irritation. Because sweat contains metabolites such as urea, lactic acid, fatty acids, etc., which are acidic substances, they are highly irritating to the skin, causing a chemical inflammatory reaction in the skin, causing the capillaries in the skin to dilate and the inflammatory cells to aggregate, leading to redness of the skin, small red papules, and itchy skin.
