What Your Fingernails Reveal About Your Health You Never Knew

2.Split or Cracked Nails

Daily exposure to chemicals and environmental factors can make nails fragile and susceptible to splitting. Fungal infections and hypothyroidism, a condition that diminishes hormone production, can also cause nails to split. If you experience other symptoms such as weight gain, depression, or fatigue, hypothyroidism may be a contributing factor. Split nails may also indicate deficiencies in biotin, protein, or iron. Frequent hand washing, cleaning agents, and cold, dry climates can weaken nails. Protecting your hands with gloves, moisturizing consistently, and consuming a nutrient-rich diet can help prevent these issues. Using nail strengtheners and maintaining nails at a moderate length can further reduce the risk of splitting and cracking.
