What it is
Athlete’s foot is a skin disease caused by a fungus, usually occurring between the toes. The fungus most commonly attacks the feet because shoes create a warm, dark, and humid environment which encourages fungal growth. The warmth and dampness of areas around swimming pools, showers, and locker rooms are also breeding grounds for fungi. Because the infection was common among athletes who used these facilities frequently, the term “athlete’s foot” became popular. Not all fungal conditions are athlete’s foot. Other conditions, such as disturbances of the sweat mechanism, reaction to dyes or adhesives in shoes, eczema, and psoriasis, also may mimic athlete’s foot.
The signs of athlete’s foot, singly or combined, are drying skin, itching, scaling, inflammation, and blisters. Blisters often lead to cracking of the skin. When blisters break, small raw areas of tissue are exposed, causing pain and swelling. Itching and burning may increase as the infection spreads. Athlete’s foot may spread to the soles of the feet and to the toenails. It can be spread to other parts of the body, notably the groin and underarms, by those who scratch the infection and then touch themselves elsewhere. The organisms causing athlete’s foot may persist for long periods. Consequently, the infection may be spread by contaminated bed sheets or clothing to other parts of the body.
It isn’t easy to prevent athlete’s foot because it is usually contracted in dressing rooms, showers, and swimming pool locker rooms where bare feet come in contact with the fungus. However, you can do much to prevent infection by practicing good foot hygiene. Daily washing of the feet with soap and water; drying carefully, especially between the toes; and changing shoes and socks regularly to decrease moisture, help prevent the fungus from infecting the feet. Also helpful is daily use of a quality foot powder.
1. Avoid walking barefoot; use shower shoes.
2. Reduce perspiration by using talcum powder.
3. Wear light and breathable shoes.
4. Wear socks that keep your feet dry, and change them frequently if you perspire heavily.
Fungicidal and fungistatic chemicals used for athlete’s foot treatment frequently fail to contact the fungi in the outer layers of the skin. Topical or oral antifungal drugs are prescribed with growing frequency. In mild cases of the infection it is important to keep the feet dry by dusting foot powder in shoes and socks. The feet should be bathed frequently and all areas around the toes dried thoroughly.
