25 Amazing Facts About The Human Body

How familiar are you with your body? The human body is a marvel of evolution that amazes scientists on a consistent basis. And why wouldn’t it? Though in many ways we are similar to other lifeforms on our planet, the human is a unique animal with traits and capabilities unrivaled in the animal kingdom. Our bodies’ unique and sometimes bizarre physiology is a testament to this. From being the only animal with the ability to cry emotionally to possessing superhuman strength (enough to even lift cars), these are 25 Amazing Facts About The Human Body You May Not Be Aware Of.

1- According to most scientists, humans are the only animals on earth who produce emotional tears.

2- Inside your belly button “live” thousands of bacteria that could literally form an ecosystem the size of an entire rain forest.

3- Contrary to popular belief sweat doesn’t smell bad. Body odor is caused when the skin’s bacteria feed on sweat. So, bacteria’s waste products cause this horrible odor.

4- In case you ever wondered what the strongest muscle in the body is, it is the tongue, while the hardest bone in the body is the jawbone.

5- Your skeleton keeps renewing itself every ten years, which means that every decade you get a new skeleton.

6- It takes seventeen muscles to smile and forty-three to frown.

7- When you blush, the lining of your stomach blushes too.

8- An average adult human is made up of about seven octillion atoms. Just to make a comparison, there are about 300 billion stars in our galaxy.

9- Despite not being the fastest or strongest animals, humans are by far the best long-distance runners on the planet. Actually, what most people ignore is that our progenitors thousands of years ago used to run after their prey until the latter died of exhaustion.

10- Within half an hour the human body is capable of producing enough heat to boil a gallon of water.

11- The focusing muscles in your eyes move around 100,000 times a day. To give your leg muscles the same workout, you’d need to walk about fifty miles.

12- Even though the brain processes pain signals, the brain itself does not actually feel any pain.

13- The smarter a person is the more dreams he or she will have when they sleep. A high IQ can also fight mental illness. Some people even believe they are smarter in their dreams than when they are awake.

14- The neurons in your brain are built differently from one another, and information travels along them at different speeds. This is why we can recall certain information instantly, while other information takes a little longer to retrieve.

15- Adrenaline gives you super human strength and that’s why in certain situations some people can lift heavy objects (such as cars) that under normal circumstances they can’t.

16- Your nose can remember up to fifty thousand scents. Furthermore, women smell and identify scents better than men.

17- We might consider it gross and clean it out every chance we get but earwax is necessary and serves as a shield for our ears.

18- While facial hair serves some purposes, the hair found on the rest of our body is practically useless and can be removed with few to no side effects.

19- A recent study shows that memory can be affected by body position. Apparently, where you are and how you are positioned in your environment can drastically trigger memory.

20- The brain operates on the same amount of power as a ten-watt lightbulb, even while you are sleeping. In fact, the brain is much more active at night than during the day.

21- Your eyes are always the same size from birth, but your nose and ears never stop growing.

22- Teeth are the only part of the human body that can’t repair themselves.

23- It is estimated that the human body has about sixty thousand miles of blood vessels.

24- When we are babies our head is one-quarter of the total length of our body, but by the age of twenty-five will only be one-eighth of its total length. This is because people’s heads grow at a much slower rate than the rest of their bodies.

25- The largest cell in the human body is the female egg and ironically the smallest is the sperm cell. A woman’s egg is actually the only cell in the body that is visible to the naked eye.
