Summer Heat, Sweaty Feet: Perfect Conditions for Fungal Infection

Foot Clinic

July 14, 2018 | A. Teav


Summer temperatures are soaring, and our feet are beginning to feel the heat. Hot temperatures can provide a perfect environment for fungal infection to thrive in our feet. Fungal infections are caused by fungi germ cells, which love dark, moist, warm environments such as between our toes and in our shoes. 

How do I know if I have fungal infection?

One of the most common forms of fungal infections in our feet is athlete’s foot (aka. tinea pedis). Some of the signs and symptoms of athlete’s foot include itching, stinging, and/or a burning sensation between the toes and sole of the foot. Fungal infections can also affect individual toenails, beginning as a white spot on our toenails and worsening into a thick, discolored, and deformed nail. As fungus builds up under the nail, it can cause it to separate from the nail bed.  

Who are at risk?


Individuals with sweaty feet, not drying well especially in between the toes after bathing or swimming, a warm/hot/humid climate, and shoes and socks that do not offer proper ventilation. All of these factors can provide the perfect conditions for the growth of fungus. Fungal infection can spread! Simply sharing shoes, socks, and/or towels with an infected person, or walking barefoot in public areas can cause the spread of fungi. Individuals with compromised immune systems are also more prone to developing fungal infections.

Tips and Advice to prevent Fungal Infection

  • Wear sandals or water shoes around public pools, showers, and locker rooms. Never go          barefoot!

  • Try to wear socks with breathable materials like cotton or wool. Likewise, try to wear shoes that allow for breathability. Avoid wearing tight shoes.

  • Dry feet thoroughly after showers, especially between the toes.

  • Do not share socks, towels, or shoes with others.

How to treat fungal infections

Treatment can vary. Typically, over the counter anti-fungal and topical creams may be effective treatments. In more severe cases, prescription medication is necessary. Visit your local Chiropodist for proper assessment and further treatment plans.
