Reason:

The temperature in the human body is 40℃, so it is ideal to take a bath with warm water at 40℃ to eliminate fatigue. Too high water temperature will consume more calories, but it will make people feel worse. When the water temperature is too low, the blood vessels contract, making it difficult to eliminate fatigue. In dog days, the water temperature can be lowered appropriately, not lower than 35℃.

Expert advice:

The temperature of the bath water should be suitable according to the season. Warm water bath (above 33℃, below normal body temperature) can be selected in summer, and hot water bath (close to or slightly higher than normal body temperature) can be selected in winter. The temperature of bath water is preferably equivalent to body temperature, not exceeding 40℃.

The best time for each bath is 15 minutes. Because it takes a long time to wash, you will feel weak all over. Fatigue is related to the concentration of lactic acid in blood. Studies have shown that after strenuous exercise, the blood lactic acid concentration hardly changes after 5 minutes of bathing, but it will drop by 7-8 mg after washing 10 minutes, and basically return to the level before fatigue after washing for 30-60 minutes.

Therefore, for ordinary office workers or light manual workers, taking a bath for 15 minutes can restore the lactic acid concentration in the body to a normal level, otherwise long-term physical exertion will make fatigue come back.
