Summer is the perfect time for a refreshing swim, but some swimmers may encounter an unwelcome surprise: swimmer’s itch or seabed eruption. While these unfortunate skin conditions can cause discomfort and concern to the untrained eye, they are generally not serious. Dr. Sobell sees quite a few of these in the clinic this time of year. Keep reading to understand and recognize these common ailments and learn how to treat and prevent them.
Swimmer’s itch
Cause: Swimmer’s itch is caused by tiny parasites called schistosomes. These parasites live mainly in freshwater lakes and ponds and commonly infect birds and mammals. However, when people enter contaminated water, the parasites can accidentally burrow into the skin, causing an allergic reaction.
Symptoms: They include red, itchy, raised bumps that appear within minutes to days after swimming. The rash usually affects areas not covered by swimwear.
Treatment: Our dermatologists recommend anti-itch lotions or corticosteroid creams to help reduce itching. They also suggest antihistamines that may reduce the allergic response.
Doctor’s order: It is important not to scratch the skin as this can lead to secondary infections.
The Seabather explosion
Cause: Seabather Eruption is caused by jellyfish or sea anemone larvae. These larvae become trapped under swimwear, leading to irritation as they excrete their toxins.
Symptoms: A red, itchy rash usually appears a few hours after exposure and may last for several days. Some people may also feel a burning or stinging sensation where the larvae were trapped. Unlike swimmer’s itch, swimmer’s rash occurs on the skin covered by the swimsuit and appears after swimming in the ocean.
Treatment: We advise you to rinse with fresh water as soon as possible after swimming and carefully remove swimwear to prevent further spread of larvae. It may also be helpful to apply vinegar or rubbing alcohol to neutralize toxins. As with swimmer’s itch, using anti-itch creams and oral antihistamines can provide relief from symptoms.
Tips for Preventing Swimmer’s Itch and Seabather’s Eruption
- #1 Avoid swimming in polluted water – Check local advice for swimmer’s itch outbreaks before swimming.
- #2 Protect your skin – Apply waterproof sunscreen to act as a barrier and wear protective clothing such as rash guards.
- #3 Rinse thoroughly – Rinse immediately after swimming in natural waters to remove any parasites.
- #4 Dry with a towel – Dry your skin vigorously with a towel after swimming to help remove parasites before they can penetrate the skin.
Both swimmer’s itch and sea urchin can be annoying, but with proper care and precautions, you can minimize their impact and continue to enjoy the water. These rashes usually go away in a few days to weeks, but if symptoms persist or worsen, it’s always a good idea to consult a healthcare professional.
