"Never Shower Barefoot at the Gym"—This Bacterium Can Cause Severe Symptoms If Infected [Health Talk]

[Financial News] There has been a warning that the habit of using communal showers at gyms barefoot can lead to serious bacterial infections. A recently released experiment video by a microbiologist has heightened awareness, as it revealed significant bacterial growth on shower floors.
On the 15th (local time), the Daily Mail reported that Nick Iker, a microbiologist with 500,000 followers, posted an experiment video on his TikTok account. In the video, Iker personally demonstrated the risks of bacterial proliferation on gym communal shower floors. The video garnered about 20,000 views and drew considerable attention.
In the footage, Iker swabbed the shower floor and cultured the sample in a special incubator. After a certain period, a thick layer of bacteria was observed in the container. He emphasized, "This is exactly why you should always wear slippers in communal showers."
Experts have long pointed out the risk of bacterial infection in gyms. Primrose Freestone, a professor of clinical microbiology at the University of Leicester, explained in a column that warm and humid environments such as saunas, showers, and swimming pools are prime breeding grounds for bacteria. She added, "Sweat contains various components such as vitamins, minerals, lactic acid, amino acids, and lipids, making it an excellent nutrient source for bacterial growth."
Staphylococcus is one of the most common pathogenic bacteria found in gyms. In particular, Methicillin-resistant Staphylococcus aureus (MRSA) can cause severe symptoms such as pain, fever, and swelling if infected. The National Health Service (NHS) has warned that MRSA, which may reside on the skin's surface, can lead to serious infections if it enters the body.
Additionally, some studies have reported cases where Salmonella was detected on gym equipment. This bacterium can cause abdominal pain, diarrhea, and vomiting, and in severe cases, may lead to dehydration or sepsis.
Jonathan Fletcher, a professor at the University of Bradford, noted that viral and fungal infections are even more common than bacterial ones, particularly warning about the risk of foot infections such as warts and athlete’s foot.
Experts therefore strongly recommend wearing slippers in communal showers, swimming pools, and locker rooms, and thoroughly drying your feet after showering as part of basic hygiene practices.
