Other risk factors include perspiring heavily, being in a humid or moist environment, psoriasis, wearing socks and shoes that hinder ventilation and do not absorb perspiration, going barefoot in damp public places such as swimming pools, gyms and shower rooms, having athlete's foot (tinea pedis), minor skin or nail injury, damaged nail, or other infection, and having diabetes, circulation problems, which may also lead to lower peripheral temperatures on hands and feet, or a weakened immune system.
Caprylic acid, one of the medium-chain fatty acids in coconut oil, has the ability to penetrate the durable cell wall of candida and other fungi. Without its protective coating the cells of the fungus dissolve, effectively destroying the infection. Apply a thin layer of coconut oil to infected areas and let it soak in for at least fifteen minutes. Coconut oil is great for skin health, so there is no limit to how often you can use this treatment. Just make sure you aren’t allergic to coconuts before applying this product to sensitive tissue.
Select shoes that fit right – Choosing the correct footwear is a must if you want to avoid toenail fungus. Shoes should not touch your toenails at all. Don’t jam your feet into shoes that are too big either – this will cause you to jam your toenail into the front of the shoe causing damage. According to the American Academy of Physicians, the best shoes have a wide toe box.
Use soap and water to wash your feet, and dry well, including between toes. Trim your toenails -- straight across -- to keep them shorter than the end of your toe. Make sure the tools you use are clean, too. Wash clippers and files with soap and water, then wipe with rubbing alcohol. You might be tempted to cover up discolored nails with polish, but don't. Your nail bed can't "breathe," which keeps fungus from going away.
