Have you heard of “athlete's foot” mycosis? Also known as tinea pedis, this is a very common (fungal) infection (among athletes in particular but not only) caused by a fungus called “dermatophyte mycosis” which feeds on the keratin of the skin and nails. Athlete's foot can be painful if not treated quickly.

The causes of cutaneous mycosis of the foot

Foot mycosisis caused by a group of fungi called dermatophytes. These develop in hot and humid areas: feet locked in shoes and socks, excessive perspiration, walking barefoot in public places such as swimming pools and changing rooms, wearing closed shoes, poor foot hygiene are all factors conducive to the development of mycosis of the skin and toes.

Infection treatments: how to avoid foot mycosis?

Good news! A few simple hygiene tips help in the treatment of athlete's foot fungus!

1. Keep your feet clean and dry: wash your feet regularly with water and cleansing gel, if possible use a dedicated and gentle formula tested on skin prone to mycosis, then dry them well, especially between the toes.

2. Cut your nails regularly and treat your calluses.

3. Wear appropriate footwear: Avoid plastic shoes and tight shoes that promote perspiration and humidity. Opt for shoes made of leather, canvas or other breathable materials.

4. Change socks regularly: Wear clean socks and change them daily or more often if you perspire a lot.

5. Avoid walking barefoot in public places: Showers, changing rooms, swimming pools and gyms are places where fungi can spread easily.

6. Take regular foot baths with sodium bicarbonate and warm water to relieve the symptoms of foot mycosis.
