3 major reasons, it hurts when you exercise
Reason 1: No exercise habits
Exercise requires a lot of blood to be transported to the whole body muscles, which is why it makes you itch. Lin Xinkai, director of the rehabilitation department and sports medicine department of Fuxin Hospital, pointed out that microvessels will expand during exercise, allowing blood to enter the muscles. When it expands, it will stimulate the peripheral nerves and have itchy feeling.
Most people who have such a phenomenon do not have exercise habits at ordinary times, and exercise exceeds physical load.

Huang Genghui, a dermatologist at Chang Gung Hospital, pointed out that some people have atopic dermatitis, which is itchy by the increase in body temperature and sweat. In addition, some people are born with “choline type urticaria”. Huang Yihui has such symptoms. Every time he chases the school bus, he runs and grabs it. He almost missed several times.

Generally, there is no need to seek medical treatment or medication. However, if the itch is uncomfortable, it is recommended that before or after exercise. Eat antihistamines to reduce itching, or see if it is caused by other causes of itching. Lin Yikai also reminded that some antihistamines can cause drowsiness. If you don’t want to have such a situation, you can remind the doctor.
Reason 3: Clothing friction
The friction of clothing and the stimulation of sweat during exercise will also be itchy. As for which materials are easy to itch, Lin Yikai points out that each body is different, so it is difficult to sum up which materials are particularly susceptible to allergies.
The University of Pittsburgh Medical Center recommends that you apply lotion before exercise to prevent it. Try different materials to test if you are allergic. You can also choose moisture wicking clothes to reduce the amount of time your sweat stays on your skin.
In addition, itching during exercise is also related to food.
