Factors that can increase your risk of developing nail fungus include:

  • Being older, owing to reduced blood flow, more years of exposure to fungi and slower growing nails
  • Perspiring heavily
  • Being male, especially if you have a family history of nail fungal infections
  • Working in a humid or moist environment or in a job where your hands are often wet, such as bartending or housekeeping
  • Wearing socks and shoes that hinder ventilation and don't absorb perspiration
  • Living with someone who has nail fungus
  • Walking barefoot in damp communal areas, such as swimming pools, gyms and shower rooms
  • Having athlete's foot
  • Having a minor skin or nail injury or a skin condition, such as psoriasis
  • Having diabetes, circulation problems, a weakened immune system or, in children, Down syndrome
