People often report itching after using a hot tub. There are two ways that this could happen: (1) bacteria; and (2) chemical irritation.
Hot tub folliculitis is an infection of the hair follicles caused by the bacteria Pseudomonas aeruginosa. These bacteria can live in the warm wet environment provided by a spa or hot tub. In order to prevent hot tub folliculitis, hot tub owners treat the water with chemicals, like chlorine or bromine, which are good at killing bacteria.
The problem with using these chemicals is that they can also irritate your skin. The chlorine or bromine reacts with your hair and skin. If you do not wash these chemicals off properly, they will irritate your skin, causing dryness and itchiness. Chlorine or bromine react with your skin cells, leaving a layer of chlorine or bromine on the surface of your skin. You may notice that you smell like chemicals? That’s because you are still covered in chemicals.
Without question, people are better off sanitizing hot tubs and dealing with the side-effects of chlorine or bromine. It is remarkably easy to get the chlorine or bromine off of your skin after swimming. To do this, just use SwimSpray after swimming.
