In contrast to wash face and feet, bathing is a full measure for cleaning body and keeping healthy. Bathing effect is due to water temperature, but "hot water is better than cold water" is not always true. The water temperature is subject to the purpose, season and individual's condition.

Normally, we bath for cleaning body, speaking from physiological and environmental condition, surface of body skin is very dirty, full of sweat, sebum and dust, all of these blocks the surface layer of skin, further more, it destroys the beauty in appearance. So we turn to bath for cleaning. Hot water should be best because sweat and sebum could be dissolved easily with hot water, the best temperature is between 38?40?(when dipping into water, hand feels a little hot)

We sometimes release fatigue, keep clean and comfortable by bathing; but hot water is not fitted for all, such as those men of bad conditions in heart, lung, and skin-disease. In these cases, warm water in 34?will be better, because this temperature is a little higher than skin and lower than body. Also, for the medical bath to cure skin disease warm water is good.
