Keeping cool during exercise in the heat depends on our sweat glands secreting a thin film of water on our skin, and then having our body's heat evaporate that water. Wearing clothing affects this process in different ways: 1) sweat can soak the clothing, changing how it insulates and protects the body; 2) sweat can be trapped between the skin and clothing, increasing discomfort and slowing sweating rates; and 3) sweat moving to the outer surface of clothing means that some of the heat for evaporation comes from the air rather than the body, making sweating less effective.

在炎热的天气下运动时保持凉爽取决于我们的汗腺在皮肤上分泌一层薄薄的水膜，然后让身体的热量蒸发这些水份。穿着衣服会以不同的方式影响这一过程：1）汗水会浸湿衣服，改变它绝缘和保护身体的方式； 2）汗水可能滞留在皮肤和衣服之间，增加不适感并减慢出汗率； 3）汗水移动到衣服的外表面意味着蒸发的部分热量来自空气而不是身体，从而降低了出汗的效果。
