This Body Part Can Reveal Clues About Your Lifespan And Inner Health
Nail growth is typically rapid until age 30, after which it naturally declines. However, continued rapid nail growth requiring frequent trimming after this age may indicate slower biological ageing of essential organs like the heart, kidneys, liver, skin, and lungs

Many people consult astrologers about their lifespan or undergo regular checkups to assess their internal organ health. While both are valuable in their own right, now you don’t have to make frequent visits. Dr David Sinclair from Harvard Medical School has suggested a simple method to estimate potential lifespan and internal organ health.
Nail Growth After Age 30

Dr Sinclair suggests that healthy nails reflect internal health. Good nail growth indicates that internal organs are ageing slowly and cells are in good condition. This slow ageing process implies less internal damage, which is positive.
Nail growth is typically rapid until age 30, after which it naturally declines. However, continued rapid nail growth requiring frequent trimming after this age may indicate slower biological ageing of essential organs like the heart, kidneys, liver, skin, and lungs.
Fast-Growing Nails May Indicate Longevity
Dr Sinclair explains that consistent nail growth after the age of 30 suggests longevity. Nail growth typically decreases by about 0.5% each week after this age. If nails still grow quickly, necessitating weekly or more frequent trimming, it suggests healthy, well-functioning vital organs, potentially extending lifespan.
Ageing slows blood circulation, affecting nutrient delivery to extremities, including nails. Reduced blood flow means less nourishment, potentially hindering nail growth and overall organ health. Conversely, healthy nail growth signifies proper circulation and vitality.
Dr Sinclair notes that changes in nail appearance can also reveal health conditions. Discolouration, ridges, and poor nail health may be early indicators of underlying deficiencies or diseases.
