Summer is a great time for a refreshing swim, but some swimmers may experience unpleasant surprises: swimmer’s itch or sea rash. Although these skin problems can cause discomfort and worry to the untrained eye, they are usually not dangerous. Dr. Sobell sees more of them at the hospital, this time of year. Read on to understand and recognize the diseases that result from this, and learn how to treat and prevent them.
Swimmer’s Itch
Because: Bather’s itch is caused by invisible parasites called ringworm. These parasites live in lakes and freshwater ponds, and often infect birds and mammals. However, when people go into contaminated water, the bacteria can get into the skin the wrong way, causing it to break down.
Signs: Includes red, itchy, raised bumps that appear within minutes or days after swimming. These rashes usually affect areas not covered by swimwear.
Support: Our dermatologists recommend anti-itch lotions or corticosteroid creams to help reduce itching. They also provide antihistamines that reduce itching.
Doctor’s order: It is important not to scratch the skin because this can lead to secondary infections.
Seabather explosion
Because: Seabather eruptions are caused by jellyfish larvae or sea anemones. These maggots get caught in swimwear, which causes them to become irritated when they release toxins.
Signs: A red rash starts a few hours after exposure and lasts for a few days. Some people may also feel a burning or stinging sensation where the worms are trapped. Unlike swimmer’s itch, swimmer’s rash appears on the skin covered by the swimsuit and occurs after swimming in the ocean.
Support: We recommend washing with fresh water as soon as possible after swimming and carefully removing swimwear to prevent the spread of worms. It may also be helpful to apply vinegar or rubbing alcohol to reduce toxins. As with swimmer’s itch, using anti-itch creams and oral antihistamines can help reduce symptoms.
Tips for Preventing Swimmer’s Itch and Seabather’s Eruption
