Why Is It Called Athlete's Foot?

Athlete's foot gets its name because athletes often get it. Why? The fungus that causes it can be found where athletes often are. The fungus grows on the warm, damp surfaces around pools, public showers, and locker rooms. People walk barefoot on these surfaces and fungus ends up on their feet. Or they might use a damp towel that has the athlete's foot fungus on it.
But just having the fungus on your feet isn't enough to cause the infection. The infection happens if conditions are right for the fungus to grow. The fungus likes it wet, so:
Dry your feet properly after swimming, showering, or bathing.
Do not wear tight shoes when your feet are sweaty.
Do not wear the same pair of shoes or socks day after day.
