Do hair and nails keep growing after
death ?
Hair and nails actually keep growing
after death or they do not?
Maybe we just imagine that they keep growing because when we
die, our body system stops working. So hair and nail are impossible to keep growing.
However, there are
some people who still believe that hair and nail still lengthen even if we are
dead. Maybe it’s possible? So if it’s possible how they can grow and how long
can hair and nails grow?
Have you ever wondered about this?
I’d collected the data from lot of sources.
Then I found data which can answer my doubt as follows:
è Appearance
of increased length created by shrunken soft tissues
o
What actually happens is the skin loses moisture. When we die, our body dehydrates. As our body is
made out of 70% of water so this cause skin shrinks and “this give appearance of increased length
because of the optical illusion created by contrasting the shrunken soft
tissues with the nails or hair'' refer to British Medical Journal article
titled Medical Myths.
è Why hair and nails don't shrink
?
o
The only part of hair which is alive is
the follicle (a small spherical group of cells) and when that dies, you will be
bald as your hair falls out. But hairs and nails don't shrink during funeral
time because they used some moisturizing cream on their body and hair, this
stops it from shrinking. And if they didn’t use moisturizing cream, your hair would
have fallen out and you would go bald.
è Hair and nail need
oxygen and glucose to grow.
o
In order for nail to grow, new cells need to be produced. Keratin cells
that form the nail plates on the ends of the toes and fingers are produced by a
layer of tissue beneath the base of the nail called the matrix. As it produces
new keratin cells, the older cells are pushed forward. This makes the nail
appear to lengthen from the tip.
o
The growth of hair has a similar process like nails. The matrix will
only produce new keratin cells while it receives adequate nutrients. It does not happen after death because
when we die oxygen supply to the brain is cut off and glucose is not
synthesized.
è Hair and nails can grow a tiny bit after death (a liitle truth)
o
There is a little truth about the growth
of hair and nails after death because death isn’t an instantaneous process.
When our heart stops beating our brain cells which need adequated oxygen die
very quickly. But cells that use less oxygen can live a little longer. So
potentially hair and nails could grow a tiny bit after dead.
Most data from above shows and supports that hair and nails can’t keep growing after death.
Although the last data tells that hair and nails can grow a tiny bit after
death, they just grow a tiny bit in short time. Most people may not observe
the growth of hair and nails.
In my opinion, I
believe and have confidence that hair
and nails can’t actually keep growing after death and what about you? Do you
believe my myth?
