12 Interesting Facts About Nail Fungal Infections

A person's feet. Recent statistics shows that least 5% of people suffer from nail fungus infection and it's common with age.

A nail fungal infection, or onychomycosis, is a fungal imbalance that affects the fingernails and toenails. [1] The most common symptom is a thickening and discoloration of the nail to yellow, green, and even black. As the concern progresses, the nail bed can become uncomfortable, brittle, and even begin breaking off. [2]

How Common is Nail Fungus?

Nail fungus is surprisingly common and occurs more frequently with age. According to recent statistics, at least 5% of people suffer from nail fungus infection. [3] Although less visible, toenail fungal infections are more prevalent than fingernail.

Toenail fungus isn't an isolated concern, it can reveal a lot about a person's health. A nail infection may suggest that the nails are receiving poor circulation or that the immune system is affected. [4]

Solutions and Tips

The standard solutions include oral and topical agents, removing the infected nail, and laser therapy. Naturopathic therapies, however, are less toxic, less harsh, and more readily available. Sunlight therapy, essential oils such as tea tree or oregano oil, and hydrogen peroxide are all common, natural remedies for fungal infections. Other simple tips for fighting nail fungus include:

  • Keep your feet as clean and dry as possible.
  • Wear waterproof sandals at swimming pools and other public wet areas.
  • Wear clean, fresh socks daily.
  • Trim your nails regularly.
  • Avoid tight hosiery; they can promote moisture retention.
