Reason:
During exercise, the body's metabolism is vigorous, heat production increases, heart rate increases, sweat evaporates, skin blood vessels dilate, and blood flowing to target muscles increases. After the exercise stops, this situation will continue for some time. In addition, the skin will continue to heat up, blood vessels will dilate, and blood flow will increase obviously, which will make the blood flow in other parts of the body decrease relatively, which is manifested as a drop in blood pressure. If you take a bath immediately, it will stimulate the blood vessels of the skin to further expand and make the blood flow highly concentrated, resulting in insufficient blood supply to important organs of blood circulation, such as the heart or brain, and blood pressure will often be lower.
Especially when the bath water temperature is high, sweating will increase, which will induce water loss in the body and easily cause dizziness, general weakness, falls and other emergencies. Especially for patients with cardiovascular and cerebrovascular diseases, it is not advisable to take a bath immediately after exercise.

Expert advice:
Take a restorative rest after exercise, and the bathing time should be delayed to 1 hour after exercise. When the body returns to the state before fitness, it is necessary to take a bath. The water temperature is 35~37 degrees Celsius, close to body temperature, neither too cold nor too hot.
In addition, it is not advisable to take a cold bath after exercise. Taking a cold bath will immediately close the pores of the body, shrink the capillaries and block the circulation between the body and the outside world. Although the body feels refreshed in a short time, it blocks the emission of body heat, which is not conducive to muscle recovery and is easy to catch a cold or have a headache.
