If you are wondering how long you will live, the answer may be right on your fingertips.
According to Dr. David Sinclair, a professor of genetics at Harvard Medical School, your nails are actually a clear sign of your biological era.
And unfortunately, getting the most frequent manicures will not provide any improvement.
“The rate of growth of your nails is a really good indicator of how you are getting old or not aging,” said Dr. Sinclair recently in his longevity in Podcast.
“Whenever I need to cut the nails, I’m thinking,” How long have I cut down the nails? “,” He added.
Sinclair mentioned a 1979 study in which researchers attached small measuring tapes to 271 individuals and monitored their nail growth over several years.
They found that the rate of nail growth decreases by approximately 0.5% per year starting at the age of 30.
This suggests that the degree of nail growth can serve as a simple, non -attractive indicator of biological aging – defined as “old” the body is based on the efficiency of your cells and tissues, compared to your chronological era, which It shows how many years you have been alive.
If you find yourself that you need to cut your nails more often than your peers, this may be a sign that you are going well in the biological era department.
Natural naturally for nails to grow more slowly and become more fragile or yellowish as you grow old. However, in some cases, changes in your nails can be a sign of a fundamental health issue.
For example, white or pale nails can signal anemia, liver disease, heart failure or malnutrition. Yellow nails can indicate fungal infections, diabetes or thyroid disease.
While vertical ridges are a common sign of aging, deceived nails can also be caused by nutritional deficiencies or autoimmune diseases such as rheumatoid arthritis.
And the club – a condition in which nails become curved and thick – can indicate lung disease, inflammatory intestinal disease, cardiovascular disease or liver issues.
The rate of nail growth may indicate aging, but if your nails are weak and break down more often, there may be other causes in the game.
Dr. Mary Stevenson, a dermatological surgeon in Nyu Langone, said many factors can lead to fragile nails, easy to chip. One is not getting enough protein in your diet, which will lead to less keratin, the protein that makes up our nails. Nutrition deficiencies in vitamin B and iron can also damage.
Washing hands, using corrosive cleaning materials such as plate soap and cleansing and trauma to the nail bed can also weaken the nails.
She also warned against cutting the cuticles during a manicure.
“We need our cuticles. Pushing these back and removing them separately the seal they make with our nail to keep things such as bacteria and fungi, ”she said.
“Leaving your nails ‘breathing’ or having free time from manicures is not essential for healthy nails, though too much acetone or abrasive manicure that can be removed with nail thinning and acetone soaking, or improper manicures may to weaken our nail. ”
She recommended biotin and iron to strengthen and extend the nails, but noted that it takes supplementary months to see a change.
