Many people like to keep fit, not only because exercise is good for health, but also because young people like to sweat after exercise. Often at this time, people always want to speed up their recovery and feel relaxed after taking a shower. So is it a hot bath or a cold bath? After reading Bian Xiao's article, all fitness enthusiasts will understand.

If you take a cold bath after strenuous exercise, your skin will suddenly be stimulated, causing blood vessels to contract immediately, increasing the resistance of blood circulation, and reducing the body's resistance, making people prone to illness. Taking a hot bath will continuously increase the blood flow to the skin, leading to insufficient blood supply to the heart and brain, dizziness in light cases, collapse and shock in severe cases, and easily induce other chronic diseases. Usually, many people like to take a hot bath after exercise, thinking that it can decontaminate and restore fatigue. In fact, the body has not returned to normal after exercise, so it is not appropriate to take a bath immediately, especially a hot bath. According to the research of sports medicine experts, when people exercise, the blood flowing to muscles increases and the heart rate accelerates. When exercise stops, blood flow and heart rate will be relieved, but it will last for a long time. If you take a bath immediately, it will increase the blood flow to your skin and muscles. In this way, the remaining blood is not enough to supply other important organs, such as the heart and brain, which leads to heart disease.
