Can I complain about the hot and cold water in the hotel?

You can complain that the bath water in the hotel is hot and cold. This is because the service is not in place and has not been debugged in advance.

The temperature of hot water bath is between 38℃ and 40℃, which can cause vasodilation, promote blood circulation, relieve muscle spasm and have sedative effect. Insomniacs take a hot bath before going to bed, which is helpful to sleep and can also reduce skin itching. Hot water bath can remove dirt from skin, make pores and sweat glands unobstructed, and improve skin metabolism and disease resistance.
