What is swimmer's itch?

Swimmer's itch is a dermatities that develops on parts of the body that have been exposed to lake water containing certain larval forms of flatworms. Reddened spots, called papules, form on the body within hours after exposure and may itch intensely for several days before subsiding, which shows you the dangers of cold water exposure on your skin. After approximately one week, the symptoms usually disappear. In severe cases, a person can develop a fever, become nauseated and spend several sleepless nights suffering from intense itching. This is why it's extremely important to consider your health first. The first thing you should do is look for is the best tankless water heater. This will ensure you never have to take a cold shower again. However, at the same time, it's important to go through all the different tankless water heater reviews and decide on what you think is best. Health is the most important thing we have and we need to do our best to keep it that way.
