I regularly see patients who complain of red, itchy rashes after swimming in a hot tub or pool. Many people initially think it's heat rash or allergies, but in fact it's often a case of pseudomonas folliculitis – also known as hot tub fever or spa folliculitis.
The condition is caused by the bacteria Pseudomonas aeruginosa , which thrives in moist environments such as hot tubs, spas, and sometimes even poorly cleaned swimming pools. When the skin is exposed to this bacteria, the hair follicles can become inflamed, leading to small red bumps or blisters that itch or sting. The rash most often appears on areas that have been covered by swimwear, especially on the back, buttocks, and thighs.
Pseudomonas folliculitis is usually harmless and usually resolves on its own within one to two weeks. To relieve itching and speed healing, you can use mild antibacterial washes and avoid squeezing the rash. A moisturizing lotion containing propylene glycol may also be helpful, as it makes the skin environment less favorable for bacteria and reduces irritation.
To prevent recurrence, it is important to keep hot tubs and pools thoroughly cleaned and to always shower after swimming. These simple self-care tips often go a long way and rarely require medical attention.
Since this type of folliculitis often affects the back, it can be difficult to access the skin to lubricate it yourself. This is where the Evolvience Reach Back Lotion Applicator can be a great help. It makes it easy to apply creams without spillage, is hygienic and easy to clean under running water, made of skin-friendly, hypoallergenic material of the highest quality - for smooth and effective self-care at home.
