Preventing toenail infection

Here are tips for preventing toenail fungus,from the Mayo Clinic's website:

• Short, dry and clean nails that have been cut straight across are less likely to become chipped, stubbed or to irritate surrounding skin, creating openings for fungus.
• 
  After bathing, the area between toes can trap moisture and encourage fungal growth unless you thoroughly dry your feet before stepping back into shoes.
• 
  Socks made with synthetic materials that wick away moisure can keep feet dryer than cotton or wool socks. But even such "high-tech" fibers will become saturated when your feet sweat excessively. Changing socks during the day is a smart tactic.
• 
  Anti-fungal sprays or powders can be sprayed or sprinkled on your feet and the inside of your shoes.
• 
  Trimming or picking at the skin around your nails can give germs an opening.
• 
  Fungi thrive in the warm, moist environs of pools, showers and locker rooms, but if you wear shoes or sandals you're less likely to step into a little colony.
• 
  Nail polish and artifiical nails can trap moisture and worsen an infection.
