How much should the hot water temperature in the guest room bathroom be controlled?

There should be no one in the guest room. With the electric water heater, a person can take a bath at 40 degrees in summer and 55 degrees in winter, which is generally enough. Experts remind: the temperature of hot water bath should not be too high, generally warm water of 35 ~ 40℃ is appropriate. The number of times of washing should not be too much, because too many times will wash off all the oil normally secreted on the skin surface and the protective flora normally parasitic on the skin surface, which will easily cause skin itching and other diseases, and the skin's resistance will be weakened, but it will easily get sick.
