Swimwear and hygiene
Germs, bacteria, and mold can grow very quickly on wet bathing suits. Medical professionals warn that wearing damp swimwear for long periods of time can cause a number of infections and rashes in children and adults, and warn against sharing bathing suits with others. They suggest that changing out of a wet bathing suit right away can help prevent vaginal infections, itching and/or jock itch.
