Hot tubs can harbor microorganisms which can cause rashes on the skin. Some people may also develop a rash after using the hot tub in the form of chemical dermatitis following exposure to chlorine. These can be prevented by making sure that hot tubs are cleaned regularly and that the chlorine levels of the water are kept at tolerable levels.
