Clinically, some people will experience flushing after exercise, especially those who do a lot of exercise, sweat more, and have fairer skin are more likely to appear. The main reason for this is that, clinically, the first aspect is that after strenuous exercise, the body’s heat production increases, which leads to increased heat dissipation, peripheral vasodilation, and then hair follicle expansion, which leads to sweating. On the other hand, when exercising, the body will increase the contraction of the heart and sympathetic excitation in order to compensate for the nutrients needed for exercise. Sympathetic excitement also leads to expansion of the peripheral blood vessels, resulting in increased sweating. This is why you will find many people blushing after exercise, which is normal. Note that after exercise, do not drink some particularly cold water, to drink some room temperature water. And do not immediately stop the exercise after rest, to carry out a slow descending process, for example, the patient after running to walk, slowly let the body’s mechanism to regulate. Generally speaking, it takes about 20-30 minutes to recover and the problem is not serious.
