Athletes foot occurs when the tinea fungus grows on the feet. You can catch the fungus through direct contact with an infected person, or by touching surfaces contaminated with the fungus. The fungus thrives in warm, moist environments. Its commonly found in showers, on locker room floors, and around swimming pools.
Athletes foot can spread if you scratch the itch and then touch other parts of your body, including your groin (jock itch) and the skin under your arms. It can also spread to other parts of your body via contaminated sheets or clothing.
Like hydrogen peroxide, rubbing alcohol can help kill off the fungus thats on the surface level of the skin. You can apply it directly to the affected area or soak your feet in a footbath of 70 percent rubbing alcohol and 30 percent water for 30 minutes.
The various kinds of fungi that cause athletes foot grow best in warm places such as bathroom floors and rugs, shower stalls, near heated pools and hot tubs, plus in socks, shoes and other clothing. Skin contact with the fungi, however, is usually not enough to cause athletes foot.
