The science behind mutual attraction

Usually, when we fall in love with someone, it seems to happen quietly, just like the mistletoe that quietly grew on Harry and Cho Chang's heads before they kissed in the Room of Requirement.

I believe that many people have beautiful fantasies about love. When talking about the concept of choosing a partner, there will be a lot of subjective descriptions. But when you really start dating, you will find that the person is not the one you imagined before.

Why are they attracted to each other and develop feelings for each other when they are obviously not each other's favorite type? There is a special term for this, and everyone calls it fate.

Fate is something that is hard to explain, so it is covered with a beautiful and mysterious veil. My purpose today is to uncover this veil and show you the science behind the attraction between two people.

Well, to put it bluntly, it’s actually the brain that does it! The goodwill or attraction between you and anyone is a series of complex calculations made by the brain at certain moments .

In addition, our five senses are also involved. These five brothers are not simply participating in the experience, they have the right to score your candidates. Even, each of them has a veto power.

Eyes are one of the first senses to exercise power. Just like the song goes, "Just because I saw you more in the crowd", just one glance, love may come.

Everyone has different aesthetics, but there are some features that are always popular, such as smooth hair, delicate and smooth skin, etc. These are what the eyes like to see.

When seeing these things, the pupils will dilate and the brain will instruct the body to move closer instinctively, because it is the genes that tell the body that these characteristics are helpful for reproduction .

After the eyes meet, the nose will start its performance. Don't think that the nose can only smell perfume and shower gel during the relationship. It also has a very important job, which is to identify "pheromones", a natural chemical signal .

Pheromones are a type of pheromone, also known as external hormones. They have a communication function, can transmit the sender's physiological or genetic information, and can also stimulate some psychological and behavioral reactions in the receiver .

Here are two interesting experiments.

The first one was a male experiment: first, a group of women in different menstrual cycles were asked to wear the same clothes for three consecutive days. Then these clothes were collected together with new clothes that had not been worn and randomly given to the male subjects to smell.

According to the saliva sample data, when men smell the clothes worn by women in their ovulation period, there is a significant increase in testosterone . This means that the brain will tell you to pay attention to this woman.

The second experiment was conducted on women. Women's noses are particularly sensitive to a chemical called MHC (Major Histocompatibility Complex). This type of substance is a collective name for a group of genes that encode the major histocompatibility antigens of animals . It is closely related to the body's immune response.

The experiment also collected clothes with different male scents and asked female subjects to smell and finally choose one of them. The data showed that the vast majority of women were more inclined to choose clothes with different scents from their own MHC molecules .

In fact, it is not difficult to explain that choosing someone with different immune genes from your own will improve the immunity of your offspring. This is a very good condition for reproduction.

In terms of hearing, most men like to listen to high-pitched, breathy, and long-resonant voices, while women like the opposite. So when the ear hears a satisfactory sound, it usually tells the brain to pay attention to the speaker.

If one of your potential love partners passes the assessment of the first three brothers, then you will face the most crucial stage of taste and touch: the first kiss !

Don't underestimate the first kiss, it is a place for the exchange of tactile sensations and various chemical information. A failed first kiss will reduce the attraction a lot. It may even make all the previous levels fail.

A successful first kiss is one that the body likes very much.

When you kiss, your blood and adrenaline boil; your brain activates the body's "fighting system"; your heart beats faster to provide more oxygen; your pupils dilate; and your body releases more glucose for energy.

To help you focus, adrenaline creates a kind of tunnel vision that prevents your attention from wandering, and it may even distort your sense of time and activate memory areas . This may explain why people remember their first kiss so well.

After these rounds of testing, your brain will analyze which one has the highest attractiveness score. It is not so much that you choose your love partner, but rather that your body's senses converge or reject those budding attractions.

The person you like the most is most likely because most of your body's senses are satisfied with him/her. But even if your body has chosen for you, you may not necessarily have a partner. You still have to ask whether the other person's brain is satisfied with you.
