Fungus only thrives in dark, moist environments and cannot survive in direct light. In fact, UV rays have a natural anti-fungal effect. One simple and cost-effective way to help treat your fungal toenail is to expose it to bright and drying sunlight.*
It could take three to six months of daily direct sunlight exposure to rid your nail of fungus. Expose your feet to as much natural light as possible. Wearing sandals is one way to help your feet get more sunlight exposure.
