Hello, itching is related to basic feelings such as touch, pressure, pain, temperature and cold.

You shouldn't feel itchy at first. Itching only occurs after running for a certain period of time. Because the body surface temperature began to rise after exercise or because of other reasons, the originally dry skin began to appear small cracks. At other times, it should be painful, but because the degree of pain is very low, there will be a feeling of itchy brain.

Suggestion:

1. Wear long pants when running in winter to prevent obvious changes in body surface temperature in a short time and also prevent water loss;

2, the application of skin insulation products, keep the skin moist.

Best wishes.
