Nail fungus is commonly caused by moisture and lack of ventilation. Fungi thrive in warm, damp environments, making the area beneath and around the nail a prime location for growth when it is consistently exposed to moisture. This can happen in situations where hands are frequently submerged in water, particularly if they are not subsequently dried properly, or when feet are kept in non-breathable footwear.

In contrast, excessive filing may affect the nail structure or the surrounding skin but is not a direct cause of fungal infections. Overuse of nail polish might lead to weak nails or other cosmetic concerns, but it does not create the right conditions for fungal growth. Frequent hand washing can be beneficial for overall hand hygiene, though if hands are not dried effectively, it could potentially contribute to moisture retention, it is not a significant risk factor for nail fungus compared to stagnant moisture in enclosed or non-ventilated areas. Thus, the failure to provide adequate airflow and allowing moisture to accumulate is what primarily leads to conditions suitable for nail fungus to flourish.
