Sitting in a Wet Bathing Suit
A common way to get a yeast infection is for the skin to come into contact with moisture from an external source. Wearing clothes that leave the area between a woman’s legs damp for extended periods can lead to this moisture accumulation, prompting yeast growth. Wet bathing suits and underwear, especially for several days in a row, can create this situation.
When you wear a bathing suit for extended periods without changing out of it and drying off, you wear a warm, moist environment all day. That creates the prime conditions for yeast to grow. The warmth from your body and the water from a pool create an environment perfect for yeast to flourish. When you don’t change out of your bathing suit soon after swimming, you’re allowing that moisture to stay against your skin for hours at a time—allowing the yeast to feast on it quickly. Your bathing suit might be dry on the outside, but a thin layer of moisture can create perfect conditions for a yeast infection.
