The most important effect of regular physical activity on the skin is to increase the blood circulation of the skin. For people who don't engage in sports activities, the blood volume of skin and limbs is much less than that of abdominal cavity. Physical activity can make blood flow to the extremities, make the skin get more nutrition and increase the ability of oxygen absorption. This is very beneficial to skin care.

Sports activities can not only promote the opening of tens of thousands of tiny blood vessels that penetrate the skin, but also gradually increase the quality and quantity of red blood cells that transport oxygen in the long run, which is very beneficial to skin cells and the whole body. Another advantage of it is that it can raise the temperature of the skin. When we engage in sports activities, our bodies will generate a lot of heat, and at the same time, our bodies must emit excess heat. At this time, the blood plays the role of a circulating cooler, bringing excess heat in the body to the body surface to dissipate heat. The more heat is generated, the greater the blood flow to the skin. Due to strenuous exercise, the skin temperature will rise from 86 degrees Fahrenheit or 90 degrees Fahrenheit to 94 degrees Fahrenheit.

People who often participate in physical exercise have fewer facial wrinkles than those who don't exercise, and those with thick skin have fewer wrinkles than those with thin skin. Because sports activities increase the nutrition of the skin and make the skin thicker. The speed of collagen synthesis may be affected by temperature and activity, so physical activity fills the skin in some way.
