What happens with the body during physical activity in nature?
When we are actively moving, we emit a large amount of local heat. The body reacts to this by active perspiration, especially intense in certain areas on our body. It can occur even in cold weather. In this case, if sweat and excess heat are not transferred from the skin, clothes become wet, and after the cessation of active movements, the body will begin to freeze.

Fabrics
Natural fabrics do not fit. It is better to give preference to synthetics. Body temperature should be maintained in the optimal zone. It is necessary that the T-shirt is made of a material that quickly absorbs moisture and brings it outside without holding it in fabric for a long time. The tight T-shirt is especially crucial for speed training, so it is better to give preference to models that fit snugly to the body.
