Visiting a swimming pool, gym, sauna, or public shower has a positive impact on health, physical fitness, and overall well-being. However, these places are also among the most common sources of fungal infections affecting the feet and toenails. Constant moisture, high temperatures, and large numbers of visitors create ideal conditions for pathogenic fungi to thrive. These microorganisms can survive for extended periods on floors, rubber mats, benches, and other surfaces.

Fungal foot infection (tinea pedis or athlete's foot) is one of the most common dermatological conditions worldwide. Without timely prevention and treatment, it can spread to the toenails, cause skin cracks, persistent itching, unpleasant odor, and even lead to secondary bacterial infections.

In this article, we explain how fungal infections are transmitted, who is at increased risk, and which preventive measures can help protect your feet after visiting swimming pools, gyms, saunas, and public shower facilities.

Why Public Places Pose a Risk

The most common causes of fungal infections are dermatophytes. Less frequently, infections are caused by yeast-like fungi of the Candida genus and other fungal species.

Fungal spores can remain viable for long periods on:

  • tiled floors;

  • rubber mats;

  • wooden platforms;

  • shower stalls;

  • changing room benches;

  • towels;

  • sports equipment;

  • shared footwear.

Fungi multiply especially rapidly in warm and humid environments, making swimming pools, bathhouses, and saunas particularly high-risk locations.

How Infection Occurs

An open wound is not required for a fungal infection to develop. Even tiny skin cracks or softened skin after prolonged exposure to water can become an entry point for fungal pathogens.

Infection most commonly occurs through:

  • walking barefoot;

  • contact with contaminated surfaces;

  • using someone else's towels;

  • sharing footwear;

  • using sports equipment that has not been adequately disinfected.

For this reason, even people who carefully maintain good personal hygiene are not completely protected from infection.

Who Is at Increased Risk?

The likelihood of developing athlete's foot is significantly higher among people who:

  • regularly visit swimming pools;

  • attend fitness centers;

  • participate in professional sports;

  • experience excessive sweating;

  • wear tight or closed shoes;

  • have diabetes mellitus;

  • suffer from poor blood circulation;

  • have a weakened immune system;

  • have previously had fungal infections.

The risk also increases with age due to the natural decline in the skin's protective functions.

Early Symptoms That Should Not Be Ignored

The first signs of infection may not appear immediately after exposure.

The most common symptoms include:

  • itching between the toes;

  • dry skin;

  • flaking or peeling;

  • redness;

  • a burning sensation;

  • small skin cracks;

  • unpleasant foot odor;

  • whitish deposits on the skin;

  • thickened skin.

If the infection spreads to the toenails, they may change color, become thicker, and develop structural abnormalities.

Basic Prevention Rules

Most fungal infections can be prevented by following a few simple hygiene rules.

Do Not Walk Barefoot

Always wear your own rubber flip-flops or shower sandals in public showers, saunas, swimming pools, and changing rooms.

Even taking just a few steps barefoot may be enough to become infected.

Use Only Personal Items

It is not recommended to share:

  • towels;

  • socks;

  • slippers;

  • footwear;

  • foot care products.

Using only personal belongings significantly reduces the risk of transmitting fungal infections.

Dry Your Feet Thoroughly

After taking a shower, you should:

  • dry your feet thoroughly;

  • pay special attention to drying the spaces between your toes;

  • use disposable paper towels if necessary.

Moist skin creates favorable conditions for fungal growth.

Choose the Right Footwear

After exercising or swimming, it is advisable to change into dry, well-ventilated shoes as soon as possible.

It is recommended to choose footwear with:

  • natural materials;

  • good ventilation;

  • the correct fit;

  • regular drying after use.

Change Your Socks Every Day

People with excessive sweating may benefit from changing their socks even twice a day.

The best choices are socks made from:

  • cotton;

  • bamboo fiber;

  • modern moisture-wicking materials.

Control Excessive Sweating

Excess moisture is one of the main factors contributing to the development of fungal infections.

For prevention, you can use:

  • special foot powders;

  • antiperspirants designed for feet;

  • drying products;

  • moisture-absorbing insoles.

Disinfect Your Footwear Regularly

Even after successful treatment, fungal spores may remain inside your shoes.

For prevention, it is recommended to:

  • use specialized disinfectant sprays;

  • dry footwear completely after use;

  • replace insoles regularly;

  • air out athletic shoes periodically.

Maintain Healthy Skin

Any damage to the skin of your feet should be treated as soon as possible.

Pay particular attention to:

  • calluses;

  • chafing;

  • skin cracks;

  • cuts;

  • excessively dry skin.

Fungi penetrate the skin most easily when the skin barrier is damaged.

Do Preventive Antifungal Products Help?

After visiting places with a high risk of fungal exposure, a healthcare provider may recommend preventive use of topical antifungal products, especially for individuals who belong to high-risk groups.

However, medications should not be used without consulting a healthcare professional. A dermatologist can recommend the most appropriate preventive regimen based on your individual health condition and risk factors.

How to Care for Your Feet After Visiting a Pool or Gym

After exercising or swimming, it is advisable to follow this simple routine:

  1. Wash your feet with clean water.

  2. Dry your feet thoroughly.

  3. Pay special attention to the areas between your toes.

  4. Put on clean, dry socks.

  5. Change into dry footwear.

  6. If necessary, apply preventive products recommended by your doctor.

These simple steps take only a few minutes but can significantly reduce the risk of fungal infection.

When to See a Doctor

Do not postpone a visit to a dermatologist if, after visiting a swimming pool, sauna, or gym, you notice:

  • itching;

  • skin peeling;

  • cracks;

  • redness;

  • burning;

  • blisters;

  • changes in nail color;

  • thickened nails;

  • an unpleasant odor that persists even after washing.

Early diagnosis makes it possible to quickly confirm or rule out a fungal infection and begin treatment before complications develop.

Common Mistakes to Avoid

Many people unknowingly increase their risk of infection.

The most common mistakes include:

  • walking barefoot in public places;

  • wearing damp shoes;

  • using someone else's slippers;

  • not drying the feet thoroughly;

  • ignoring the first symptoms;

  • self-treating without a confirmed diagnosis;

  • stopping treatment as soon as symptoms temporarily improve.

Avoiding these mistakes significantly reduces the likelihood of developing athlete's foot.


Swimming pools, gyms, saunas, and public showers remain places with a high risk of exposure to fungal infections affecting the feet. However, following simple hygiene practices, wearing personal footwear, drying your feet thoroughly, maintaining proper skin care, and seeking prompt medical attention when the first symptoms appear can effectively prevent the development of fungal infections.

Remember that preventing fungal infections is always easier, less expensive, and more effective than undergoing prolonged treatment. Taking proper care of your feet after every visit to public facilities helps prevent unpleasant complications, maintain walking comfort, and preserve a high quality of life.
