With the arrival of the heat, the Fungal infections of the skin become much more frequentespecially during the summer months. Increased temperature, humidity, and perspiration create the perfect environment for fungal skin infections to take hold and persist, particularly when combined with the intensive use of swimming pools, changing rooms, and shared showers.
In European countries with temperate climates, such as Spain, a clear increase in superficial fungal infections During the summer months, these infections are common in both adults and children. Dermatology experts emphasize that, beyond the cosmetic concern, these infections can become chronic if not treated properly, which is especially relevant for people with weakened immune systems or chronic illnesses.
Why do fungal skin infections increase during the summer?
The main reason for the increase in cases at this time is the combination of intense sweating, heat and humidityWhen the skin remains damp for a long time, especially in folds and poorly ventilated areas, it facilitates the growth of fungi that are already present in the environment or on the skin itself.
During the holidays it is common spend more time at beaches, pools and spasas well as using public showers and changing rooms. These environments, if not thoroughly sanitized or used without foot protection, become common points of infection. Simply walking barefoot on wet floors significantly increases the risk.
Furthermore, the use of tight-fitting clothes or clothes made of synthetic fabrics In summer, combined with high temperatures, sweat accumulates and doesn't evaporate properly. This frequently occurs in the groin, armpits, and between the toes, areas that are already prone to skin maceration.
In the European context, where many cities have community swimming pools, gyms and sports complexes In very crowded places in summer, specialists remind us that exposure to contact with unknown people increases the likelihood of coming into contact with fungi, even if the other person does not have a confirmed diagnosis.
Areas of the body most affected by fungi in summer
Dermatologists agree that body areas that remain more humid and with less ventilation These are the areas that cause the most problems in summer. Among the most frequent are the feet, especially the soles and the spaces between the toes.
The well-known “athlete's footIt appears easily when wearing closed shoes for many hours, wearing socks that don't breathe well, or walking on wet floors without protection. This infection is characterized by scaling, itching, and sometimes small, painful cracks in the skin.
Another problem area is the inguinal regionIn areas where humidity, friction, and high temperatures favor fungal infections that appear as reddened patches with well-defined borders and persistent itching. This type of infection is more common in people who play sports, wear tight underwear, or sweat excessively.
The armpits and other skin folds They are also susceptible to fungal growth, especially in overweight individuals or those living in hot and humid climates. In these environments, the skin can become irritated, reddened, and develop a rash. stronger smell than usual.
Finally, the Toenails are often affected When they spend a lot of time in a humid environment, such as closed sneakers or poorly ventilated shoes, the nail may change color, thicken, and become more brittle over time.
Typical symptoms of a fungal skin infection
Recognizing the initial signs is key to Act in time and prevent the fungus from spreadingThe first symptoms often include mild peeling of the skin, accompanied by moderate itching that intensifies with heat or sweat.
It is also common to observe redness and small irritated areaswhich in some cases take the form of circular or oval plaques. Unlike many allergic reactions, which tend to be more diffuse, fungal infections tend to show more active, slightly raised borders, with a somewhat clearer center.
When the fungus affects the nails, it produces visible changes in their appearanceThey turn yellowish or whitish, thicken, and may become more opaque. Over time, the nail becomes brittle and may even become deformed.
In some cases, if the infection is left untreated, the The discomfort can progress from a simple itch to painThis is especially true when cracks appear in the skin or when footwear puts pressure on the affected areas. This not only makes walking or playing sports difficult, but it can also lead to further bacterial infections.
Who is most vulnerable to fungal infections in summer?
Although anyone can develop a fungal infection, there are groups that present a higher riskespecially during the summer. This includes people with chronic illnesses, such as diabetes, or those with weakened immune systems due to medical treatments or underlying conditions, and in some cases, measures to strengthen the immune system are recommended, such as... echinacea.
In babies and young children, specialists point out that The family environment is usually the main route of infectionIf an adult in the household has fungal infections on their feet or nails and does not receive treatment, they can easily transmit them to children through shared surfaces, towels, or direct contact.
People who practice intense exerciseEspecially in enclosed facilities like gyms or indoor swimming pools, people spend more time in damp clothing or athletic shoes, increasing their exposure. In summer, combining exercise with the ambient heat multiplies the risk.
Those who are also more susceptible They frequently use public changing rooms, spas, or bathing facilities.These are very common in many European cities. Although these spaces usually have hygiene standards, the high volume of people allows fungi to thrive on floors and damp surfaces.
How to prevent fungal skin infections in hot weather
The good news is that, with simple and consistent hygiene habitsThe likelihood of developing fungal infections in summer can be significantly reduced. Dermatologists recommend paying special attention to cleansing and drying routines during this time, and in some cases, considering the use of natural products such as [product name missing]. coconut oil.
One of the basic measures is Wearing flip-flops or sandals in public showers, swimming pools and changing roomsAvoiding walking barefoot on wet floors cuts off one of the main routes of contagion, both in outdoor facilities and in indoor spaces.

It's advisable wash swimwear, socks and sportswear Wash clothes after each use and let them dry completely before using them again. In summer, people sometimes reuse damp clothes "because they're still clean," but this damp environment encourages fungal growth.
At home, it's advisable Keep bathroom and shower floors as dry as possibleVentilate the room after each use. Stagnant water and constantly damp surfaces create a perfect environment for mold to thrive and spread from one family member to another.

If, despite preventive measures, they appear reddened spots, persistent itching, or changes in the nails If symptoms do not improve within a few days, it is best to consult a healthcare professional, ideally a dermatologist, for an accurate diagnosis.
One of the most common mistakes is resorting to self-medication with over-the-counter products without medical guidance. Many of these preparations combine antifungals with corticosteroids, and the inappropriate use of corticosteroids can mask the infection: symptoms improve temporarily, but the fungus remains active.
When these types of treatments are interrupted without medical supervision, the The infection may reappear with greater force.This makes it more difficult to eradicate and prolongs the problem for months. That's why a clear diagnosis and following the specialist's instructions are so important.
The doctor will assess the location, extent and characteristics of the injuryIn some cases, additional tests may be ordered to confirm the type of fungus. Based on this, a topical, oral, or combined treatment will be prescribed, always tailored to each patient's individual situation.
In people with pre-existing conditions, compromised immune systems, or in young children, the Professional supervision is especially importantbecause these infections tend to be more persistent and require closer monitoring.
Experts agree that skin fungi multiply in summer due to the heat, humidity, and intensive use of shared spaces, but they insist that with good hygiene, appropriate clothing and footwear choices, care in swimming pools and changing rooms, and avoiding self-medication, it is possible to prevent them.
