How fast do human fingernails grow?


No particular context as to why this question came to my mind. Nevertheless, here’s the answer.

The rate of growth of human fingernails varies, depending on the person, the nail in question, and the time of year. As a general rule, human fingernails grow between half an inch (one centimeter) and four inches (10 centimeters) per year, and a number of things can influence this growth rate. Incidentally, fingernails grow approximately five times as fast as toenails, for those who are curious.

Among the many factors which influence the rate of growth is age. Younger people tend to grow their fingernails more quickly, especially if they eat healthy, varied diets.

Longer fingers appear to grow nail material more quickly, as do the fingers on the dominant hand. On most people, the middle finger of the dominant hand grows a nail most quickly, while the thumb or pinky of the other hand has the slowest rate of nail growth.

Human fingernails appear to grow more quickly during the daylight, which means that they also grow more during the summer, when daylight hours are increased.

Contrary to popular belief, human fingernails do not continue to grow after death. The illusion of growing fingernails is created by the dehydration which the human body experiences after death. As the body dehydrates, soft tissue starts to shrink and pull away, which can make it look as though the hair and fingernails have grown. The shrinking tissue can also expose the teeth, which explains why the dead appear to be grinning.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
