Do You Want To Understand Your Body More? Read Some Of The Most Interesting Facts About It

Our body is probably one of the most intriguing secrets that are yet to be discovered and researched. However, science has done a pretty good job demystifying the ways our body function. Getting to know these secrets will shed some light on how to keep your body healthy.

I did not write about all the interesting facts. Thus I have chosen those facts that are both educational and informative for every person who wishes to know more about the human body.

 

1. The age of atoms in our body

Given that hydrogen was produced 13.7bn years ago, and carbon and oxygen between 7bn and 12bn years ago, our body is ancient. The fact that every atom in our body is billions of years old makes you wonder about it.

 

2. The sensitivity of our eyes

Our eyes are able to detect just a few photons of light. When we are looking at Andromeda constellation, which is the nearest galaxy, we are looking in time through 2.5m years.

 

3. The scents we can remember

Our nose is a pretty much remarkable sense, we can remember 50,000 different scents. We all have a unique smell, but women smell better than men, and are able to identify smells more precisely and accurately.

 

4. The unique tongue print

Many believe that fingerprints are the only way to confirm and discover one’s identity. However, most people are wrong because every person in the world has a unique tongue print, and this print can also be used to discover or hide someone’s identity.

 

5. The growth of our fingernails

If you have ever wondered why you need to dedicate so much time to clipping your fingernails, it is because fingernails grow fastest.

The nails that are exposed and used frequently, especially on the hand you write with, and on the longest fingers, are growing very fast. Every month nails grow about one-tenth of an inch, on average.

 

6. The truth about snoring

Although very irritating, the sound of the snore is only around 60 decibels, as opposed to normal speech, which can reach more than 80 decibels (loud as the sound of a pneumatic drill breaking up concrete).

When normal speech reaches 85 decibels, it is considered hazardous to the human ear. As for the snoring habits, by 60 years of age, 60 percent of men and 40 percent of women will snore.

 

7. The skin shedding

We complain about our pets shedding problem all the time, but the truth is that humans shed about 600,000 particles of skin every hour. By the age of 70, the average person will lose around 105 pounds of skin.

 

8. The truth about the new stomach lining

Every three to four days we get a new stomach lining. The acids in the stomach that are used to digest food also digest the stomach.

 

9. The details about the world we see

The world we “see” is artificial – our brain produces an image the way a video camera produce it. The image of the world is constructed from the information provided by modules that measure light and shade, curvature, edges and more. The brain also gives a false picture of a steady vision because it compensates for the rapid jerky movements of our eyes.

 

10. The story behind goose pimples

Goose pimples occur when tiny muscles around the base of each hair tense and pull the hair more erect. Goose pimples are a remnant of our evolutionary predecessors.

 

11. The number of bacteria on the human body

Different bacteria cause serious medical illnesses and problems in our bodies, but the truth is, and a very scary one, that every inch of skin on the human body has about 32 million bacteria on it. We are lucky that the majority of these bacteria are harmless.

 

12. The speed of a sneeze

Although a habit, sneezing can be harmful if we do not cover our nose. The truth is that the air from a human sneeze can travel 100 miles or more per hour. With this speed, it can easily seed viruses and bacteria if we do not cover the nose.

 

13. The fascinating facts about the brain

The brain does not feel pain even though it processes the pain signals. It is made of 80 % of water, and that is why you need to remain properly hydrated. Our brain requires 20 % of the oxygen.

The brain is more active when we sleep, and it stores everything one feels, sees, hears, and reads, etc., although we cannot recall everything. The memory is affected by the body position as well, and a place and the position in the environment triggers memory also.

When we sleep, we dream more if we have a higher I.Q. The information in our brain travels at different speeds. During puberty, the brain changes shape.

 

14. The sense of hearing

When you overeat your sense of hearing decreases. You need to have healthy eating habits because when you eat too much, your ability to hear reduces. We also use sound to sense objects in the area using echolocation. The blind can very effectively develop this ability.

 

15. The growth of teeth

The teeth are growing before birth, six months before you are born. Although we need to pay special attention to its proper growing from a very early age, we also need to consider their health even before we are born, in fact, the mothers should enjoy a healthy and happy pregnancy.

 

16. The sweat from the feet

There are 500,000 sweat glands in our feet (250,000 each) and we produce more than a pint of sweat a day.

 

17. The height of the body

In the morning we are all taller. Throughout the day, because the cartilage between our bones is compressed, we are in fact about 1 cm shorter by the end of the day.

 

18. Our body in space

If our body were pushed from the spaceship without a suit nothing will happen to it, there will be no explosions or anything similar as presented in the movies. We will feel a certain discomfort because the air inside the body will expand.

The blood is what will keep us just fine because it is kept under pressure by the circulatory system. We would not feel cold very quickly also, although space is very cold. Lack of air is what would kill a person in space.
