After exercise, you usually sweat all over. Everyone wants to take a bath as soon as possible to refresh themselves. How long is it appropriate to take a bath after exercise? Because our muscles are constantly contracting during exercise, in order to meet the needs of exercise, the heart rate will also be accelerated, the blood circulation will be accelerated, and the blood flowing to the muscles and the heart will increase. After exercise, the blood flow is slow and the heart rate slows down, but it will take some time to return to the state before exercise. If you take a bath at this time, the blood vessels of muscles and skin will expand, blood will continue to flow to muscles and skin, and the blood supply to the heart and brain will be insufficient, resulting in dizziness and weakness. Therefore, it is recommended to take a proper rest for about 30 minutes after exercise, and you can start taking a bath when your body returns to the state before fitness. However, you should pay attention to taking a warm bath, which is usually completed within 5- 10 minutes. If you exercise in summer, you should pay special attention not to take a cold bath immediately.
