35 Incredible Facts About The Human Body
That Might Surprise You
It is amazing what the human body is capable
of. Its potential is greater than you might imagine. Some of the facts you are
about to read may seem unbelievable but they are actually true and most of them
are processes that are happening in your body right now.
o
The speed of the nerve impulses that travel
from and to the brain reaches up to 250 miles per hour.
o
Our bodies completely replace our old skin
with a new one every month. In his lifetime, a person sheds 40 pounds of their
skin.
o
The atoms that our bodies are made of are
13.7 billion years old as they are the same ones that were formed during the
Big Bang.
o
Some people, and in particular WOMEN, have
the ability to see a wider range of colors than an average person can. Most of
us have 3 types of color receptors, but some WOMEN have 4 or 5 of these.
o
Humans have the best endurance when it comes
to long-distance running. In the past, thousands of years ago, we used to run
after the prey until they no longer had energy to go on.
·
With every new pound of FAT or muscle
you gain, your body produces seven miles of new blood vessels.
·
Our fingers are sensitive to such extent that
if they were the size of our planet, we would be able to tell the difference
between a car and a house.
·
The strength of our bones can be compared to
the strength of granite. A matchbox sized block of human bone could support 9
tons.
·
When we are in love, our bodies release the
same variety of neurotransmitters and hormones that are released when under the
influence of amphetamines. The common symptoms are loss of sleep and appetite,
feelings of excitement and increased heart rate.
·
The muscles in our eyes that are responsible
for focusing, move 100 000 times every day. If you want to do the same
workout but with your legs, you would have to walk 50 miles.
·
Our bodies give off so much heat for 30
minutes that would be enough to boil a gallon of water.
·
50% of a human’s DNA is the same as a
banana’s.
·
Our eyes are impressively sensitive organs,
too. They are so sensitive that if the Earth was flat, you could see a candle
burning at night from 30 miles away.
·
When a pregnant woman experiences some kind
of an organ damage (a heart attack, for example), the fetus can help with the
recovery process as it sends stem cells to the damaged area. What is more,
women who have been pregnant can show neurological protection against the
disease.
·
Ever wondered what the inside of your
bellybutton looks like? Well, it contains thousands of bacteria forming an
ecosystem that can be compared to the size of a rainforest.
·
A head of human hair can support up to 12
tons.
·
You might think that the only senses a person
has are sound, touch, taste, sight and smell. Well, there are 15 more (balance,
pain, temperature, thirst etc.).
·
The amount of hair we have all over our
bodies is equivalent to a chimpanzee’s. Only ours may seem more invisible as it
is lighter and finer on parts of our bodies.
·
If our brains were computers, they could
perform 38 thousand-trillion operations for a second. In comparison, the most
powerful supercomputer in the world can do only 0.002% of that.
·
The human body has around 60 000 miles of
blood vessels in average. The Earth can be circumnavigated two and a half times
with that length.
·
One sperm has 37.5mb of male DNA in it that
is needed to create a child. An average ejaculation is equivalent to 1.500
terabytes of information.
·
The human muscles are actually much more
powerful than you might have thought. When in a dangerous situation, our bodies
release adrenaline which provides us with the energy rush we need to preserve
ourselves. There are people who have managed to lift boulders or cars off
themselves. In normal conditions, our strength is limited in order our tendons
and muscles to be prevented from harming.
·
Synesthesia is a condition that causes senses
to overlap which means that some people can feel the taste of words and hear
the sound of colors.
·
90% of the cells in our bodies aren’t human
cells. They are mostly bacteria.
·
A person can read up to 1000 words for a
minute.
·
There are around 0.2 mg of gold in our
bodies. It is contained mostly in the blood. But if you wanted to make a single
8g coin out of gold of the human body, you would need the blood of around 40
000 people.
·
An adult person is actually made up of
7,000,000,000,000,000,000,000,000,000 atoms. To get a clearer picture in your
head, just remind yourself that there are 300,000,000,000 stars in the galaxy
we are in.
·
It is proven that when a person is lonely, he
feels physical pain. And just you have an instinct to keep away from physical
pain, you have the same drive with avoiding loneliness.
·
Every 13 seconds your body produces more
cells than there are people in the USA. Each second it produces 25 million new
cells.
·
We glow in the dark! The problem is that the
light we emit is 1000 times weaker than our eyes can see.

The lining of your stomach starts blushing,
if you do.

body (4 times the distance from coast to coast across the US).

Our brain’s microstructure is similar to the
structure of the universe. The connection between the neurons in the brain is
analogous to the way the world is structured.

Crying decreases the feelings of anger or
