However, if the bath time is too long, it may have side effects, leading to hypoxia in the body, or it is not conducive to the blood circulation of the body, especially in a closed environment, which is prone to syncope symptoms due to hypoxia. Also be careful not to take a bath just after exercise, because at this time, due to the increase of exercise, the muscles are in a state of tension and contraction, and the heart rate will also accelerate.
If you take a bath at this time, the blood vessels of the skin and muscles will expand, and the output of the heart to the surrounding tissues will increase, while the blood supply to the heart and brain will decrease, which will easily aggravate the symptoms of cardio-cerebral ischemia and hypoxia.
