What is the primary cause of fungal infections in nails?

1. Excessive nail polish use

2. Moisture and warmth

3. Soaking nails in cold water

4. Using non-sterilized tools

The correct answer is: Moisture and warmth

The primary cause of fungal infections in nails is moisture and warmth. Fungi thrive in environments that are damp and warm, which is why they are commonly found in places like swimming pools, locker rooms, and in shoes that do not allow for proper ventilation. When nails are regularly exposed to such conditions, it creates an ideal breeding ground for the growth of fungi, leading to infections. Other factors like excessive nail polish use, soaking nails in cold water, and using non-sterilized tools can contribute to nail health issues but do not directly cause fungal infections. For instance, excessive nail polish may lead to poor nail health due to lack of moisture but does not necessarily promote fungus growth. Similarly, soaking nails in cold water does not create the warm, moist environment that fungi require for growth. Using non-sterilized tools may increase the risk of bacterial infections or other pathogens, but not specifically fungal infections. Thus, understanding the optimal conditions for fungal growth clarifies why moisture and warmth are the primary contributors to these types of infections.
