Top 15 Mysteries of The Human Body

Share This Post

The human body is a fascinating organ machine that is a complex system in itself. It is full of different unresolved mysteries and complexities. Our human body is the basic support system that we can rely on but it can come as a great shock to many that what they think about the human body is not absolute.

Mentioned below are the top 15 fascinating mysteries of the human body.

1. Fingerprints

We are all well versed in unlocking our phones and protecting passwords with our fingerprints. With the increasing population, the human race is presented with a huge diversity. One another mystery of the human body revolves around the fact that no two people including identical twins possess the same fingerprints. This can be termed as the direct reason for swirly patterns which are still treated as a mystery to humankind.

2. Appendix

Appendix for many years was regarded as a body part with absolutely no use. Initially, it was believed to have been the leftover of the process of evolution. It was centered around the belief that this vestigial structure would cease to exist with the slow process of evolution. This was a subject of serious discussions among scientists as appendix baffled scientists with their unknown reason for existence and continue to do so.

3. Dominant Hand

Hands form an integral part of our lives. They are involved in various processes of life. The concept of the dominant hand is still a mystery to many. As children, most of us enjoyed comparing our dominant hands with our peers’ dominant hands, categorizing ourselves as “right-handed” or “left-handed.” No lucid explanation as such is available to support this claim as to why one hand has better functionality than another in most people.

4. Yawn

We all yawn and this yawning has been related to several theories time and again. One of the ancient theories states that it can increase blood circulation to the brain. Some researchers claim yawning is a result of fatigue. One set of theorists believes that yawning helps in regulating the air pressure in the middle ear. Research is still being carried on to find out something related to yawning but the true reason for yawning remains a mystery even today despite a humongous array of theories available for the same.

5. Blood Types

There are different blood types such as Type O, Ab, A, and B. These blood types are regarded as a part of evolution. A theory insists on the fact that these different blood types and their emergence is nothing but merely protection against a particular set of infections. However, there has been no definitive explanation as to the reason for the existence of various blood types.

6. Dreams

Freud, a famous psychologist worked largely on dreams and their interpretation. He believed that every thing is it our thought or action started deep in our brain and dreams were directly related to the brain. He proposed several interpretations of dreams. Humans spend nearly 1/3rd of their lives asleep yet the reason for why we dream when asleep remains still shrouded in mystery.

7. Contagious Laughter

Laughter is contagious is a phrase that most of us have encountered often. It is quite literally true to some context but no one really understands why it is contagious. Several theories have proposed their explanations of this phrase but the most accepted one is that humans are empathetic beings therefore our brains release endorphins when we laugh, making us happy.

8. Déjà vu

Science has yet to provide a satisfactory answer to the question of why we experience déjà vu. Mostly, it is linked with memory. It is also termed “a glitch in your brain”. Neurologists propose a myriad of theories and one of the states is that déjà vu occurs due to the misfiring of neural pathways linked to memories.

9. Crying

Tears help in keeping the eyes healthy. On a physiological level, tears are useful for clearing away irritants in the eyes and they also protect eyes from external irritants. Our tears automatically roll down when we are sad making it quite clear that they are tied to our emotions. It is somewhat strange that only human beings as a species have their tears tied to their emotions and no one else.

10. Microbes


Not many are aware that microbes live in and on the human body and while they often aid us in our daily tasks such as digestion, the use of more than half of the microbes found in our body is unknown, as is the reason why we share a symbiotic relationship with them.

11. Self-Consciousness

Many scientists and researchers for decades have been hustling around the complexities of humans. Self-consciousness is the greatest of all. The human mind is quite perplexing and one of the greatest mysteries about the human body is the sense of self-created by the human mind. Its origins and what it stands for are still a matter of debate.

12. Chimpanzee Strength!

Humans differ in strength greatly when compared with animals especially with primates such as chimpanzees as they are much alike in musculature yet it is still unknown to many researchers and scientists why chimpanzees are more than three times stronger than humans.

13. Stuttering

Doctors cite several reasons Emotional, genetic, and physical factors induce stuttering yet the root cause of stuttering is unidentified till date.

14. Memories

While it is obvious that humans store memories in their mind, no body knows the exact location for storage of memories.

15. Personality

There is a divide among scientists as to whether personality comes from the brain or the environment one was raised in.

It is fascinating and ironic to contemplate how little we know about our own selves even as we go on to dive deeper into the oceans and further into the space. Forever curious to learn more, perhaps we should take some time to understand our own selves before trying to understand the world outside.
