A hot tub rash is a common occurrence on the skin of people who use hot tubs on a regular basis. However, this type of skin problem may also affect certain individuals who only use a hot tub once in a while as well.
Many people are often surprised that after using a hot tub they have developed a body rash. Why is the skin rash there? What caused the skin rash to develop? Is this rash dangerous? How do you treat a skin rash as a result of using a hot tub?
Chemicals in the Water
The principle cause of a skin rash from hot tub is due to chemicals, leading to a chemical dermatitis skin condition. Like swimming pools, hot tubs contain chemicals to kill bacteria and sanitize the water. Chlorine is generally used, but sometimes other chemicals may be used or additional products may be present. These chemicals can be harsh on the skin. For some people, the hot tub rash may develop after first exposure, but for many it develops after repeated exposure to the pool chemicals. The skin becomes sensitized to the constant exposure to chemicals and a skin rash develops. The effect is magnified for many people because the water is warm or hot. If you develop a hot tub skin rash, avoid using a hot tub on a regular basis to allow the skin to desensitize to the chemicals. Definitely do not use the hot tub until the rash disappears and the skin recovers. Alternatively, experiment with different concentrations of sanitizing chemicals or different types of sanitizers. You may be able to find a combination that does the required job of sanitization, but does not irritate the skin.
A skin rash from a hot tub may also be caused by dirty water or water with too much bacteria in it. Without proper treatment of hot tub water, bacteria can grow rapidly because of the warm water condition. Individuals may react to the bacteria and a skin rash and possibly other illnesses may develop. A proper balance of sanitizing chemicals is very important in preventing a hot tub skin rash.
Finally, the heat of the water can cause a heat rash in some individuals. Cool off the skin and keep it dry to help soothe the skin and eliminate the rash.
