The champignons proliferate more easily in humid and hot environments. We must therefore take care to counteract these factors.

• Wear shoes that provide good ventilation and stockings that absorb perspiration well. Prioritize cotton or wool socks, which absorb moisture well.
• Spray the feet and the inside of the shoes with a powder or antifungal aerosol.
• Change socks when they are wet.
• All right dry feet out of the shower.
• Wear some sandals in public showers in swimming pools and sports centers and on any damp or wet surface.
• Keep toenails brief.
• Disinfect the instruments used to clean the nails in a alcohol solution.
• Clean your hands after touching the infected nail. Do not share the bath towel. The infection can spread.
• Do not put nail polish on a nail with onychomycosis. This can encourage the persistence of the infection.
