In summer, if the environment is hot and the skin is sweaty, it is advisable to take a shower every day to avoid itching and serious fungal or bacterial infections due to sweat impregnation. When the skin is impregnated with sweat the skin barrier function is damaged and sometimes infected with viruses such as common warts, infectious molluscum contagiosum, etc. So if you sweat a lot, it is advisable to take a shower every day in summer to remove the sweat stains, and you need to change your clothes. If you are working in a cool environment, you don’t need to take a shower every day. Generally, normal people can take a shower twice a week.
