On February 18, Dr. David Sinclair, a longevity expert, said that nails are an important sign that indicates how long you will live, which is why you should monitor the growth of your nails, unless you are someone who neglects nail care. Your nails can help you know how much life is left in you.
Dr. David Sinclair is a legend in the world of genetics and is renowned for his research on why we age and how we can slow down the effects of the passage of time. He has been teaching biology of aging and translational medicine at Harvard Medical School since 1999, so he definitely knows a lot about aging. This 55-year-old Australian academic revealed that you can get insights into the amount of fuel left in your body just by keeping an eye on your nails.
“The rate of nail growth is a good indicator of whether you’re getting older or not,” Dr. Sinclair recently said during his Lifespan podcast. “Every time I have to cut my nails, I think, ‘How long has it been since I last cut them?'”
He explained that the health of your nails can tell you a lot about the rate at which your body is producing new, healthy cells, and the faster this process, the better Dr. Sinclair said that rapid cell turnover means you have a younger biological age, as this process slows down as you fully mature.
“All of this comes from a study in 1979 where they taped these little measurements to people’s nails and measured them over many years,” the expert said. The research found that the weekly nail growth rate decreases by about 0.5% each year after the participants turned 30.
“And really, when you look at thousands of people, we now know for sure that the rate of nail growth declines [by] about half a percent per year,” Dr. Sinclair continued. “If you measure that, it’s a pretty good indicator of how old you are biologically.” Dr. Sinclair admitted that while he doesn’t currently measure the size of his nails, he “pays attention to whether my nails are growing more slowly.” His co-host Matthew Laplante also admitted that he doesn’t track the length of his nails, saying, “I bite my nails, which I know is a really bad habit.” Essentially, science suggests that if your nails continue to grow quickly compared to others your age, you may be aging more slowly than them.
So, give yourself a pat on the back if you have some nice, long nails.
As you get older, your body will produce less keratin, causing your nails to become more brittle, according to Dr. Michelle Henry, founder of Skin and Aesthetic Surgery of Manhattan.
She previously told Huff Post that “as we age, our bodies start producing less of the natural proteins found in our nails, which can make nails become brittle, dry, and more prone to cracking.” “These keratin proteins are also found in our pores, which is why we may see changes in our hair texture as we get older.”
