Swimmer's itch is a disorder of the skin that manifests in the formation of a rash over the parts of the skin that are exposed to water while swimming. It is caused when the skin comes into contact with a parasite called cercaria, released into fresh or marine water by aquatic snails. The parasite embeds itself into the skin, causing it to react and form a rash. It is not a life threatening disorder, but can cause a lot of unnecessary irritation. Common symptoms of swimmer's itch include a tingling, burning or itching sensation over the affected area once you have emerged from the water.
The best recommended method of dealing with swimmer's itch is to dry yourself off immediately with a soft cotton towel. The skin is sensitive at this time and making use of a coarse, synthetic towel could cause further damage. Washing the affected area with baking soda should cause the itching to stop within minutes. Soaking the affected areas in a warm oatmeal bath is also known to reduce itchiness and sensitivity of the skin. Instances of severe itching and burning can be overcome by the application of calendula lotion and calamine lotion, which soothe the skin. It is also recommended that soft soaps and cleansers be used while bathing because sensitive skin could be further damaged by soaps that contain harsh chemicals. Bees wax soaps are extremely gentle and helpful in cleaning sensitive skin.
A pack made of Fuller's earth and water is known to relieve symptoms of a rash and is therefore recommended. The pack should be left on for a few minutes and washed off with fresh water. Similarly, a mixture of one part of tea tree oil to ten parts of castor oil will help in clearing out the parasites that cause swimmer's itch. Another paste that can be used to cool and ease the rash is made by mixing sandalwood powder and rose water. The best way to avoid swimmer's itch is to swim in deeper water where the parasite is less likely to be present. In case you are subject to repeated occurrence of the swimmer's itch, it is advisable that you avoid going into the water at that particular place. Not all people are sensitive to swimmer's itch, but with increased exposure to the cercaria parasite, sensitivity increases, putting you at risk of breaking into a rash. In the event that the symptoms do not subside within a week, it is advisable to seek medical assistance.
