What is Hot Tub Folliculitis?

Hot tub folliculitis, also known as pseudomonas folliculitis, is a skin condition where bacteria that is commonly found in warm wet areas causes an infection in the lower area of the hair follicle. While this may seem like an ailment that could only affect those from the neck up, unfortunately this is not the case.

Your body is actually covered with hair follicles. In fact, with the exception of a few areas, (palms of your hands, soles of your feet, eyelids and lips) hot tub folliculitis could strike almost anywhere on your body.

The bacteria that causes hot tub folliculitis, Pseudomonas aeruginosa, thrives in moist and wet areas. It can also survive in chlorinated water. While it can be found in any type of warm water, it seems to thrive in wooden tubs.

Along with an itchy or painful bumpy rash, many people with this type of folliculitis may also experience other symptoms. Many sufferers report feeling generally unwell and many experience a sore throat, headache or nausea.
