Nails revealing biological age

A study of more than 271 people shows that the speed of nail growth decreases by about 0.5% per year, starting from the age of 30. Experts say this may be a simple factor to guess biological age – age cells, tissues and organs. Biological age may be lower or higher than human age.

Nails grow faster than people of the same age is a sign that the biological age of people is younger than their real age. In contrast, the nails grow slowly, crunchy and yellow to prove bad biological signs. However, in some cases, changes in nails may be a sign of hidden health problems.

For example, white or pale nails signal anemia, hepatitis, heart failure or malnutrition. Yellow nails show fungal infections, diabetes or thyroid disease. The vertical lines are signs of common aging, but may also be due to nutritional deficiencies or autoimmune diseases such as rheumatoid arthritis. Curved and thick nails may be a sign of lung disease, bowel disease, cardiovascular disease or liver problems.

The speed of nails shows aging, but weak and brittle nails may be due to other causes. Dr. Mary Stevenson, a dermatologist at Nyu Langone, said many factors can lead to brittle, brittle nails. One of them is not adequate protein in the diet, resulting in less keratin, protein that creates nails. Lack of vitamins B and iron can also be harmful.

“We need the epidermis. Pushing the epidermis of the nails back or removing them will break the protective layer of the nail. People can still do nails. However, too much acetone or abrasion nail abrasion It is not necessary to thin the nails, which makes the nails weaker, “Dr. Stevenson said.

She recommended additional biotin and iron to make nails stronger and longer, but note that it takes months to see the difference.
