According to Dr David Sinclair, your fingernails can say a lot about the state of your health. In reality, he claims that there is a sign that appears on your fingernails that can reveal about your life expectancy. However, what is this sign and what should you do if you see it? Let’s find out more about the connection between this sign and life expectancy below.

Your Life Expectancy According to Your Fingernails

Dr. Sinclair states that he closely examines his fingernails regularly to determine how rapidly he is aging. Now, for most people, this is typically the last part of the body they would think of looking at to gauge their health. Most of us tend to pay more attention to our diet, lungs, heart, and overall health than our nails when it comes to determining how healthy we are. Still, according to Dr. Sinclair, the state of your nails reveals the rate at which new healthy cells are produced in your body. The quicker the rate that in which new cells are produced, the greater the protection your body has against health decline related to aging.

Signs of Biological Aging

Your actual age can very often differ from your biological age. Your biological age is determined by observing how well the tissues and cells in your body appear to function. This can be clearly observed in the rate at which your nails grow. The doctor claimed that he specifically pays attention to whether his nail growth has slowed down or not and notes how long ago he previously cut them. He made reference to a specific study conducted in 1979 in which scientists observed the growth rate of hundreds of people’s fingernails. What they found was that the participant’s fingernail growth rate slowed down by 0.5% annually from the age of 30 onwards. This suggested that if your nails grow faster than this anticipated rate, then you are aging at a slower rate than average.
