Hot tub rash is a skin infection caused by the germ Pseudomonas aeruginosa. The germ is
microscopic, so you can't see it with the naked eye. It comes from swimming or bathing in contaminated
water, such as you might find in a poorly maintained hot tub or pool. You can also get it from lake water.
However, it is more prevalent in hot tubs and spas because the water is
warmer, which means chlorine and other disinfectants break down more
quickly.
Symptoms of Hot Tub Rash
- The skin becomes itchy
-
A bumpy red rash may develop.
-
It can progress to pus-filled blisters around the hair folicles.
-
It tends to be worse under a person's
swimming suit, since the contaminated water is held close to the skin longer.
Is Hot Tub Rash Serious?
Usually, the rash will go away on its own within a few days. However, if
it persists, you should visit your doctor for medical treatment.
How to Protect Yourself from Hot Tub Rash
The easiest way to protect yourself is not to swim in suspect waters.
Often, you can tell if the water chemistry in a public hot tub is off because it
will smell a bit like bacteria and things are growing in there, as opposed to
the familiar scent of chlorine or bromine. Also, if the water is murky,
this is a sign that the chemicals aren't balance or that the water needs to be
changed. Stick to well-maintained pools and hot tubs, and you're not
likely to develop hot tub rash.
