What if your nails could give you clues about your health and even your life expectancy? According to Dr. David Sinclair, a genetics expert at Harvard, observing the growth and appearance of your nails could be a key indicator of biological aging and certain serious health problems. So, what are the signs you shouldn't ignore?
Nail growth: an indicator of aging
Dr. Sinclair points out that the rate of nail growth is a good way to measure cell regeneration . A 1979 study found that nail growth slows by about 0.5% per year after age 30. The slower your nails grow, the more likely this is to be the case.
