Introduction
Long-term use of non-breathable shoes and socks, sharing shoes, socks, foot basins, and other personal hygiene items with others, and neglecting local cleanliness are bad hygiene habits that make it easier for fungi to grow around the nails, leading to onychomycosis. One should wear breathable shoes and socks to keep the feet dry. Avoid sharing personal hygiene items with others. Regularly clean the feet, especially the areas between the toes and under the toenails.

Generally, gray nails are usually caused by onychomycosis (fungal nail infection). Onychomycosis may be caused by factors such as low immune function, poor hygiene habits, hand and foot ringworm (tinea manuum/pedis), peripheral neuritis, diabetes, and others. Measures such as general treatment and drug therapy can be taken to improve the condition. It is important to seek medical attention promptly and follow medical advice for treatment. The details are as follows:

　　

　　1. Low immune function: When the immune system is weakened, the body's resistance to pathogens such as dermatophytes and yeasts decreases, making it easier for these pathogens to multiply in the nail area and cause onychomycosis. To improve immunity, maintain a healthy lifestyle, including balanced nutrition, moderate exercise, and sufficient sleep.

　　2. Poor hygiene habits: Long-term wearing of non-breathable shoes and socks, sharing shoes, socks, foot basins, or other personal hygiene items with others, and neglecting local cleanliness can promote fungal growth in the nail area, leading to onychomycosis. One should wear breathable shoes and socks, keep the feet dry, avoid sharing personal hygiene items, and regularly clean the feet, especially between the toes.

　　3. Hand and foot ringworm (tinea manuum/pedis): Hand and foot ringworm is a fungal skin infection caused by the same pathogens responsible for onychomycosis. If left untreated, the fungus may spread to the nails, causing onychomycosis, often accompanied by itching of the skin on the hands and feet. Follow medical advice to use antifungal medications such as compound ketoconazole cream, compound miconazole nitrate cream, or terbinafine cream.

　　4. Peripheral neuritis: Peripheral neuritis may be caused by poisoning, metabolic and nutritional disorders, infections, or allergic reactions. It is characterized by symmetrical sensory and autonomic nerve dysfunction in the distal limbs, which can damage nerve endings in the nail area, leading to poor local blood circulation and insufficient nutrient supply, making the nails susceptible to fungal infection. It may also be accompanied by numbness in the hands and feet. Follow medical advice for drug treatment, such as vitamin B1 tablets, mecobalamin tablets, or ibuprofen sustained-release capsules, to nourish nerves and relieve pain.

　　5. Diabetes: Patients with diabetes have elevated blood sugar levels, which weaken the body's resistance to fungi, making them more prone to onychomycosis. Additionally, diabetic patients often have impaired skin healing, which slows recovery after infection and increases the risk of onychomycosis, often accompanied by frequent urination. Under a doctor's guidance, medications such as acarbose capsules, glimepiride tablets, or gliquidone tablets can be used for blood sugar control.

　　Maintaining cleanliness and dryness in the nail area in daily life can help prevent onychomycosis.
