Humans have long been desperate to know how long we will live. Imagine, if signs related to this are visible on the surface of your body. Of course this is possible. Recent research shows that the rate at which your nails grow can indicate your internal health and longevity.

Your body often indicates your health externally. Skin, hair, eyes and yes, nails. Can tell you a lot about your organs and overall health. Experts believe that the speed at which nails grow can reflect the health of your vital organs and even indicate your biological age.

Harvard’s well-known geneticist Dr. David Sinclair, who is doing research on aging, says that after the age of 30, if the nails grow rapidly and they need to be trimmed frequently, then it means that your organs like heart, liver, kidney, lungs and skin are functioning properly. On the other hand, slow growth of nails can be a sign of internal aging.

This is not a guess. Studies conducted on hundreds of people since 1979 found that after the age of 30, nail growth slows down by about 0.5% every week. Nails grow rapidly until age 30, then naturally slow down with age. Rapid growth after this age can be a good health signal.

How does Dr. Sinclair track it? Dr. Sinclair pays special attention to his nails while estimating longevity. He watches how often he cuts his nails and keeps an eye on the gap between cutting the nails twice. A smaller gap indicates good organ health and slower internal aging.

Factors affecting nail growth: As we age, blood circulation slows down, which reduces the access of nutrients to the nails. Nutrition, hormones and lifestyle habits also affect growth. Rapid growth during adolescence or pregnancy reflects the body’s higher nutrient needs.

Nails don’t just tell age; They may also indicate possible deficiencies or diseases. Dark marks or spots in young people may indicate a deficiency of zinc, iron, calcium or vitamin A. Experts insist on looking at nails to understand health, but for medical problems always consult a professional.
