What is the most likely result of prolonged exposure to moisture in nails?

Prolonged exposure to moisture can significantly affect the health of nails, and one of the most likely outcomes is the development of onychomycosis, which is a fungal infection of the nails. Fungi thrive in moist environments, and when the nails are consistently exposed to dampness, such as from frequent washing without proper drying or from wearing closed-toe shoes that don’t allow for airflow, it creates an ideal environment for fungal growth. This can lead to changes in nail texture, color, and overall health.

Other conditions like yellowing, brittleness, or leukonychia may occur due to various factors such as chemical exposure, nutritional deficiencies, or trauma, but they are not specifically linked to moisture exposure in the same direct manner as onychomycosis. The crucial element here is the association of moisture with fungal growth, making the risk of onychomycosis a prominent concern in situations of prolonged moisture exposure.
