Humidity and Warm Conditions
The fungus causing the athlete’s foot grows optimally in the presence of humidity. For this reason, the damp shoes and socks are much favorable for the growth and spread of the fungus, causing athlete’s foot. Lack of personal hygiene practices can also increase the chances of attaining an athlete’s foot because, in this particular situation, the fungus finds it easy to propagate and cause invasion on the skin. Mostly the fungus spreads in the feet precisely because when you wear shoes for a more extended period, there is an accumulation of sweat and warmth.
