If you work out, you’re naturally more at risk for athlete’s foot. Why? Because this common fungus multiplies in public areas such as communal showers, locker rooms, and gyms. While the infection typically starts between your toes, it can quickly spread to your toenails and other parts of your feet.
Fortunately, most cases are easily treatable with over-the-counter creams, such as Lotrimin and Lamisil. More severe cases of athlete’s foot may require prescription medication. Call your doctor if home remedies aren’t helping after a week.
Remember that it’s also very important to wash and dry your feet twice a day.
