This article features some mysteries of human behaviour that science can’t explain. The ten things we don’t understand about humans. Scientists have split the atom, put men on the moon and discovered the DNA of which we are made, but there are some mysteries of human behaviour which they have failed to fully explain. Why do we dream, kiss, blush or shy? These are the basics of human behaviour, scientists still don’t have a clue.

Top 10 Mysteries of Human Behaviour scientists still can’t explain

10. Shyness

10 Mysteries of Human Behaviour
The feeling of apprehension, lack of comfort, or awkwardness experienced. when a person is in proximity to, approaching, or being approached by other people, especially in new situations or with unfamiliar people. Shyness may come from genetic traits, the environment in which a person is raised and personal experiences.

9. Art

10 Mysteries of Human Behaviour
Painting, dance, sculpture and music could all be the human equivalent of a peacock’s tail in showing what a good potential mate someone is. However, it could also be a tool for spreading knowledge or sharing experience.
For instance, a study by Geoffrey Miller at the University of New Mexico shows that women prefer creativity over wealth when their fertility is at its peak. Others believe the drive to seek out aesthetic experiences evolved to encourage us to learn about different aspects of the world – those that our brain’s have not equipped us to deal with at birth.

8. Adolescence

Adolescence is a transitional stage of physical and psychological human development generally occurring during the period from puberty to legal adulthood. The period of adolescence is most closely associated with the teenage years. No other animal undergoes the stroppy, unpredictable teenage years. Some suggest it helps our large brain reorganize itself before adulthood or that it allows experimentation in behavior before the responsibility of later years.

7. Picking Your Nose

One in four teenagers engage in the habit, at an average of four times a day, a study found. The unappealing but common habit of ingesting ‘nasal detritus’ offers almost no nutritional benefit. So why do a quarter of teenagers do it. on average four times a day? Some think it boosts the immune system.

6. Superstition

Superstition
Superstition is a pejorative term for belief in supernatural causality. That one event leads to the cause of another without any physical process linking the two events. such as astrology, omens, witchcraft, etc. that contradicts natural science.The unusual but reassuring habits make no evolutionary sense. however, ancient humans would have benefited from not dismissing a lion’s rustle in the grass as a gust of wind. Religion seems to tap into this impulse.

5. Altruism or selflessness

Altruism
Doing good deeds is part of human nature. They just can’t decide why we do them. Altruism or selflessness is the principle or practice of concern for the welfare of others. It is a traditional virtue in many cultures and a core aspect of various religious traditions. though the concept of “others” toward whom concern should be directed can vary among cultures and religions.
After all, what is the point of helping others, if they are not guaranteed to return the favor  Robert Trivers of Rutgers University in New Jersey argues that natural selection favored our altruistic ancestors because they could expect to benefit. However these tendencies became misguided as we developed a globalized world.

4. Kissing

The act of pressing one’s lips against another person or an object. Cultural connotations of kissing vary widely. Depending on the culture and context, a kiss can express sentiments of love, passion, affection, respect, greeting, friendship, peace and good luck, among many others.
There are theories that it is associated with memories of breastfeeding and that ancient humans weaned their children by feeding them from their mouths, which reinforced the link between sharing saliva and pleasure. Another idea is our foraging ancestors were attracted to red ripe fruit and so developed red lips to tempt sexual partners.
Kissing has been shown to reduce levels of the stress hormone cortisol and increase the bonding hormone oxytocin, so is good for our health and happiness.

3. Laughter

Laughter
An involuntary reaction to certain external or internal stimuli. Laughter can arise from such activities as being tickled, or from humorous stories or thoughts. It is considered a visual expression of a number of positive emotional states, such as joy, mirth, happiness, relief, etc. On some occasions, it may be caused by contrary emotional states such as embarrassment, apology, confusion or courtesy laugh.
Laughter boosts levels of feel-good endorphins, helping us bond with others. ‘Laughing at’ can be used to push people away.

2. Blushing

Blushing
A uniquely human trait. Blushing, the involuntary reddening of a person’s face due to embarrassment or emotional stress. It has been known to come from being lovestruck, or from some kind of romantic stimulation. It is thought that blushing is the result of an overactive sympathetic nervous system.
Charles Darwin struggled to explain why evolution made us turn red when we lie, which alerts others. He called it the most peculiar and the most human of all expressions. However, some think it originally used it to diffuse aggressive approaches by more dominant individuals. Over time it became associated with higher emotions such as guilt and embarrassment.

1. Dreaming

Dream, the experience of envisioned images, sounds, or other sensations during sleep. Dreams help us process and consolidate emotions without the rush of stress hormones that would accompany the real experience. They also help with memory and problem-solving. People are better at recalling lists of related words and links between them after a night’s sleep than after the same time spent awake in the day. It was recently discovered that we can dream even outside of REM sleep. REM dreams were found to involve long stories with more emotion, while non REM dreams often involved friendly interactions.
Sigmund Freud’s theory of dreams expressing our subconscious desires have been generally discredited and it is recognised that they help us process emotions, but the reason why we see such strange visions has not been properly explained.
