Nail fungus is a widespread condition characterized by discolored, brittle, or thickened nails. The fungus, also called onychomycosis, is more prevalent in toenails than in fingernails. The condition is caused by a fungal infection that can affect several nails at once. Several causes can bring on the infection—here are the most common.

Potential Causes of Nail Fungus

1. Reduced Blood Circulation

Aging, diabetes, or other circulation problems can reduce blood flow and lead to the development of fungus. In these cases, the feet may not get sufficient blood, which is essential to healing.

2. Increased Perspiration

Fungus thrives in moist environments, which is why excessive sweating is a key cause. Athletes should seek sweat-wicking socks and shoes that promote ventilation to stop moisture from getting trapped in their footwear.

3. Tight Footwear

Extremely tight footwear can also inhibit ventilation, thereby increasing the risk of fungus. Always wear shoes with plenty of space in the toe box, and avoid styles that squeeze toes together too tightly, such as pointed-toe heels or flats.

4. Damp Locker Rooms

Although personal health and lifestyle factors are often to blame, fungal infections can also spread via common areas where people walk with bare feet. This is especially true of damp environments, such as locker rooms and pool areas. Wear sandals in public spaces to avoid coming into direct contact with the floor.

5. Genetics

If you don’t seem to have any of the risk factors above but still experience this condition, your parents could be to blame. Unfortunately, fungal nail infections appear to share a genetic risk factor. Therefore, if your family members experience fungus in their nails, you may be more likely to contract it, too.
