Don't take a bath immediately: if you take a cold bath after strenuous exercise, your skin will be suddenly stimulated, which will make blood vessels contract immediately, increase the resistance of blood circulation, and reduce your body's resistance, which is easy to get sick. 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.
Some people take a hot bath after exercise, and then often feel dizzy and weak, which is the reason mentioned above. Especially the elderly or obese, you can't take a hot bath immediately after exercise.
Don't drink too much water to quench your thirst: drinking too much water will increase the burden on the gastrointestinal tract and dilute the gastric juice, which will not only reduce the bactericidal effect of gastric juice, but also affect the digestion of food. Drinking water too fast will suddenly increase the burden on the heart, causing temporary disorder of electrolytes such as sodium and magnesium in the body, and may even lead to heart failure, chest tightness and abdominal distension.
Don't smoke: after exercise, the metabolism of the human body is accelerated. If smoking can make a lot of smoke enter the body, the body needs a lot of oxygen after exercise, so it is more susceptible to carbon monoxide and nicotine. Poor oxygen inhalation will also affect the physical recovery after exercise, making people feel more tired.
