Nails can serve as indicators of underlying health issues, with changes in colour, texture, and growth often signalling potential concerns. Specific nail changes like pale or blue-tinged nails may suggest circulation problems, while yellowing could indicate fungal infections, and brittle nails might point to nutrient deficiencies or dehydration. Experts advise that while most nail alterations are not serious, sudden, widespread, or persistent changes that do not improve over several weeks should prompt a consultation with a doctor. Diet, hydration, and stress significantly impact nail health, with biotin (vitamin B7) and adequate water intake being crucial for nail strength and preventing brittleness. Maintaining healthy nails involves daily habits such as using cuticle oil, gentle strengtheners, protecting hands with gloves, and moisturising regularly with nourishing hand cream.
