Question: 1 / 400

What is the most common cause of nail fungus?

Exposure to cold air

Fungal infections in warm, moist environments

The most common cause of nail fungus is related to fungal infections that thrive in warm, moist environments. Fungi, particularly dermatophytes, tend to proliferate in settings where there is a lack of ventilation and where moisture is retained, such as enclosed shoes or public showers. These conditions make it easier for fungi to invade the nail bed, leading to infections.

Understanding this context is crucial for prevention. For instance, maintaining good foot hygiene, wearing breathable footwear, and avoiding walking barefoot in communal areas can significantly reduce the risk of developing nail fungus.

While other causes, like improper nail trimming or using non-sterilized tools, can contribute to nail problems, they are not the primary drivers of fungal infections in nails. Cold air exposure does not create the conditions necessary for fungi to grow and thrive, making it an unlikely cause for nail fungus.
