I've noticed that my fingernails grow faster than my toenails.For toenails, the number would be about 6 to 8 weeks, but I trim my fingernails every two weeks or so.
The terminal phalanges of mammals are related to the length of the nails.In humans, fingernails and toenails grow up to four times faster than the index finger.[13]
Humans grow their nails at an average rate of 3mm a month.toenails need 12 to 18 months to grow back, and fingers need three to six months.The growth rate is dependent on a number of factors.In the summer, nails grow faster than any other season.There are no comments at this time.
Why should the growth rate of nails be dependent on the length of the terminal phalanges?Why do babies grow faster?I was not satisfied with the answer, so I looked for another article.There were two possible candidates.
Because hands are closer to the heart than feet, fingers get better blood circulation and have better access to oxygen and nutrition.
The trauma Fingernails experience through tapping, typing, bumping, and other seemingly insignificant actions is almost constant.These traumas cause fingernail growth.The toes are not exposed to as much trauma as they are bundled up in socks and shoes.The fingernails on a person's right hand grow faster than those on their left hand.
They don't give actual results.Which is the real cause of the difference in the growth rate of fingernails and toenails?
P.S.It would be great if the answer explained the season dependence and lefthand-righthand asymmetry.
