11 Important Signs Your Fingernails Can Tell About Your Health

Fingernails are the hard, flat, and protective coverings that grow on the tips of our fingers. They are made of a tough protein called keratin, which is the same material that makes up our hair and the outer layer of our skin. Fingernails serve several important functions:

  • Protection: Fingernails act as a protective shield for the sensitive fingertips and the tissues underneath.
  • Manual Dexterity: Fingernails enhance our ability to grasp and manipulate objects with our hands.
  • Scratching: Fingernails are useful for scratching and providing relief from itchiness or irritations on the skin.
  • Sensory Function: Fingernails have nerve endings that contribute to our sense of touch and sensitivity.
  • Personal Grooming: Fingernails play a role in personal grooming and are often trimmed and maintained for hygiene and aesthetic purposes.[AdSense-A] 

Fingernails grow from the base of the nail bed, located just below the cuticle. The growth rate of fingernails varies from person to person, but on average, they grow about 1/8 inch (3 mm) per month. Factors such as age, diet, overall health, and genetics can influence the rate of nail growth.

The appearance of fingernails can also provide insights into our health, as various health conditions or deficiencies may manifest as changes in nail color, texture, or shape. Regularly examining our nails can help us notice potential health issues and seek appropriate medical attention if needed.

Maintaining healthy fingernails involves keeping them clean, avoiding excessive biting or trauma, using moisturizers to prevent dryness, and maintaining a balanced diet with essential vitamins and minerals. If you have concerns about the health of your fingernails or notice significant changes in their appearance, it’s advisable to consult a healthcare professional for evaluation and guidance.
