1. Nail Growth as a Marker of Biological Age

Dr. David Sinclair, a genetics expert at Harvard Medical School, suggests that the rate of nail growth is a reliable indicator of biological aging. A study found that nail growth decreases by approximately 0.5% per year starting around age 30. Men experience faster nail growth than women until around age 60, after which women have faster growth. Regularly observing and measuring nail growth can offer insights into biological aging.

2. Changes in Nail Color and Texture

• Yellow Nails: Yellowing nails can indicate fungal infections, diabetes, or thyroid disorders. In rare cases, it may be associated with yellow nail syndrome, which can be linked to chronic lung issues or even tumors.

• Pale or White Nails: Nails that are pale or white may suggest anemia, liver disease, or malnutrition. It's essential to consult a healthcare provider if this change occurs.

• Bluish Nails: A bluish tint can indicate a lack of oxygen in the blood, possibly due to respiratory or cardiovascular issues.

• Vertical Ridges: While common with aging, pronounced vertical ridges can also be a sign of nutritional deficiencies or autoimmune diseases like rheumatoid arthritis.

• Clubbing: When nails become rounded and bulging, it may point to lung disease, inflammatory bowel disease, cardiovascular disease, or liver issues.

3. Nail Texture Changes and Their Implications

• Brittle Nails: Brittle nails can result from protein deficiencies, harsh cleaning agents, or nail trauma. Nutritional deficiencies in vitamin B and iron can also contribute to this condition.

• Thickened Nails: Thickening of nails may be associated with fungal infections or psoriasis. It's advisable to seek medical attention if this occurs.
