Why do people kiss?

She closes her eyes slowly. You put your arm around her waist and pull it close to you. You tilt your head and tighten your lips to your lips. A pervasive feeling numb all over. You wonder: "Why did I do this?".

Explain the reason why people kiss

Of course the simplest answer is that people kiss because it feels great. But for many people the answer is not satisfactory.

Until now, scientists have not been able to explain clearly where the human kiss originated, but they have come up with some new theories and explain our biological system to be affected like that. by the lip lock.

The question arises: Is kissing a learned or instinctive behavior? Some say it is learning behavior, dating back to our ancient ancestors. At that time, mothers chewed food and fed their children when they had no teeth. Later when babies grow teeth, mothers also press their lips against their cheeks to ease the pain.

And also, not all humans kiss. Some tribes in the world do not kiss. While 90% of the world's population kisses, 10% don't know what they missed.

Others believe that kissing is an instinctive act and taking the animal's cuddly behavior as evidence. While some animals rub their noses together to show affection, others also lock their lips like humans. Baboons, for example, find many reasons to kiss. They kiss to do good after fighting, to comfort others, to increase friendship, and sometimes for no reason at all.

Today, the most widely accepted hypothesis about kissing is that people kiss because it helps us "sniff" the ideal partner . When two faces are close together, "pheromones" speak , exchanging information about whether two people can jointly create healthy children. For example, women will unconsciously like the scent of the protein-rich guys in their other immune systems. This combination will create children with a stronger immune system and a better chance of survival.

However, most people are satisfied with the explanation that people kiss because it's interesting. Our lips and tongue contain a lot of nerve endings, which enhances the feeling of ecstasy in love when the lips are pressed together. Normally, that feeling doesn't make us wonder why we kiss each other but also make us do more.
