Human body’s hidden mysteries!

0

You must have thought some questions popping up in your mind, why we sleep? What are dreams and memories? How does the brain work? These questions have puzzled one and all. However, these are still mysteries of the human body waiting to be unraveled.

I am sure you did not know that human body can survive without food for a month but sleep deprivation of a few days can ruin your personality; your behavior and body functions will undergo a drastic change.

Human body is that mystery which has been keeping scientists involved in solving its secrets from ages.

Though there have been noteworthy and remarkable discoveries of human physiology and psychology in medical science, there are some phenomena that have baffled scientists for decades and still seem like a closed book. Here, we have tried to list certain facts and functions of the human body whose cause or reason still baffles experts, scientists, researchers, and philosophers alike.

The cracking sound

The cracking sound made by knuckles, necks, backs, and other joints when they’re cracked is the sound of bubbles popping in the joints’ fluid. Is it harmful? Not terribly. But cracking a joint too often can hurt the cords, called ligaments, that surround the joint.

Sweat is not smelly 

Sweat doesn’t smell bad. A stinky “body odour” is caused when the skin bacteria feed on sweat. Their waste products are what smell bad!

Presence of Microbes

For every cell in your body, there are 10 microbes that reside inside you. Some microbes and bacteria like E. coli, Bacteroides fragilis and Clostridia are present in the nose, mouth, the gastrointestinal tract, and on the skin. They help in the metabolic processes that take place inside the human body. These microbes also protect you against disease-causing pathogens and increase the production of vitamins, thus keeping you fit and healthy.

Eye colour Heterochromia

Eye colour Heterochromia is a condition in which people have different coloured eyes. It’s rare in humans (actor Kiefer Sutherland has heterochromia) but common in dogs.

Yawning

Though there are a number of reasons behind a yawn, scientists are yet to pin down a definite answer to the cause of yawning. Though it helps increase the intake of oxygen, some scientists think it is a way to prevent the brain from warming up, to make us more alert and active.

Commonly associated with fatigue, boredom, and drowsiness, some researchers think that yawning is inherited from our ancestors who yawned to show off their teeth to scare or restrain others. It may also be a way of communicating with others.

Brain is a very wrinkly organ

Working of the brain and the nervous system is probably the biggest riddle that scientists are yet to solve. How does the brain work so fast? Does the brain work alone, or rely on other organs for its smooth-functioning? What happens in various neurological disorders or injury? These questions have puzzled scientists for a long time and are still unanswered.

The Brain is a very wrinkly organ! If you spread it out, your brain would be about the size of a pillowcase. By the time you are six years old, your brain is already 90 percent of the size it will be when you are an adult.

Sleep and Dreams

Science has not been able to explain why we need to sleep in the first place. A theory suggests that sleep is essential for the development of the brain and is a restorative function which gives the body a chance to rest and rebuild for the next day. However, if that is the case, then why are our brains active during sleep.

Interesting thing is even we are sleeping but our brain is constantly alert and active. It is a mystery as to why this happens. What deepens the mystery is, why do we dream when we are asleep.

There are many theories regarding the occurrence of dreams, some scientists say that dreams are a way of analyzing things, they reflect your feelings, fantasies, or desires and may help in forming memories. Whether it is for psychological significance or interpretation of signals, the exact cause still remains unclear.

Kissing

Do you remember your first kiss? Of course, you do! It is a memory etched in your mind forever. But why do we kiss, and what is the purpose behind this act, is still a mystery.

Some scientists say it is a form of social bonding and to express your love. Some think that the act unleashes hormones to initiate mating and create intimacy. Whether it is for pleasure, attachment or a combination of psychological and biological factors, we don’t know, however a lip-lock feels good and makes you blush.

Memories

How is it that you remember the taste of the pie your grandma made, and the method/formula to solve an equation in algebra even after so many years?

Science does not have an answer to this question as well. How does your brain recall exactly what you want and when you really need some information? How do you form these memories? Where are these memories stored? These are questions that scientists have no definite answer as of now.

Blushing

That brings me to the mystery of blushing. When faced with a difficult situation, why do you get butterflies in your stomach, or turn red and feel the heat rise in your cheeks when someone compliments or praises you?

These are the questions that are yet to be answered by scientists. Do remember that it is an involuntary action, and try as you might, you have no control over.

Dead skin cells

Like dead skin cells, your hair and nails are made of keratin. Keratin forms tough body parts in other animals, too. It’s found in wool, fur, feathers, claws, beaks, hooves, horns, porcupine quills, and turtle shells.

 

Allah Almighty has created human body so amazing yet complicated which hasn’t revealed itself as whole before any science.

These processes and occurrences were, are, and will always remain an inevitable part of life. They are essential for our survival. We just hope that some day science will provide us with the answers and keys to unravel these mysteries of the human body that have puzzled not only scientists but every individual since time immemorial.
