the same protein, called keratin.
2.The nail plates are dead cells and contrary to the popular belief,
they don't breathe. So they don't require oxygen. However, the nail
beds and the cuticles are live cells and they do need oxygen, vitamins
and minerals.
3.Nails don't sweat. The nail bed does not have sweat glands, so it
can't perspire. It is the skin around the nails that gets sweaty.
4.Nails grow at the rate of 0.1 mm daily (or 1 cm in every 100 days).
So, for a finger nail to regrow completely, it takes between 4 and 6
months. For toe nails, the period of complete regrow is 12 to 18
months.
5.Men's nails grow faster than women's nails.
6.Finger nails for both genders grow faster than toe nails.
7.Toe nails are about twice thicker than finger nails.
8.The fastest growing nail is on the middle finger. The slowest – on
the thumbnail.
9.When nails are freshly cut, they grow faster than nails that are not
cut often. That is why it takes so much time to grow nails longer than
an inch (breaking nails is excluded).
10.Seasons and weather also affect nail growth. Nails grow faster in
warm climates and during daytime, than in cold climates and at night.
11.Nails grow faster on young people than on old people. Also nails
grow much faster during pregnancy.
12.Nails grow at different speeds on both hands. If you are
right-handed, the nails on your right hand will grow faster than the
nails on your left hand and vice versa.
13.Light trauma, like typing on a computer stimulates nail growth.
Well, this kind of trauma looks more like a massage actually.
14.Cutting your nails after dark is bad luck. Although this is pure
superstition, there is enough logic in it – if you cut your nails when
there is not enough light, you can injure yourself.
15.Nails reflect your health status.
16.Some mammals, for example elephants, have 5 nails on each of the
their front legs and most often only 4 nails per hind leg.
17.It is a myth that hair and nails will continue to grow for several
days after death. This is an optical illusion and is due to the fact
that the skin shrinks, thus making it look as if the hair and nails
are growing.
