Love is a chemical reaction

Scientifically, love is a chemical reaction in the body. Moreover, the statement that Cupid's arrow is aimed directly at the heart is completely untrue, because the state of love and the heart have nothing in common.

Love's habitat is a less romantic place called the brain. When Cupid hits a person, the brain begins to produce various chemicals that trigger a cascade of complex chemical reactions and leave the body in a state of bewilderment. Like a drug.

Therefore, love is chemistry, addiction, and since it is addiction, it is also a disease. Interestingly, some psychiatrists have fallen in love with the strict definition that love is a narrowing of the field of consciousness, emotional instability and deterioration of mental strength, which interfere with the normal process of forecasting.


The choice of a partner is determined by many factors. Our early experiences have a big impact, but rather the extent to which our "compartment" of emotional memory is replete with positive experiences. This "clipboard" is located between the cerebral cortex and the hippocampus and is filled from the moment of birth. The more pleasant and good emotions there are, the more likely it is that new stimuli will be associated with old experiences.

It is believed that, connecting with the positive emotions of the past, at some point in life we ​​meet love, and no one knows why in the form of this person. Scientifically speaking, this feeling is caused by the one who has the appropriate "correct" pheromones, and it is they who cause the so-called piercing storm of blood. In the face of pheromones, people are defenseless, and the claim that love is a chemical reaction becomes a reality.

Smell 2

It can be said that people subconsciously sniff, which also undermines the theory of love at first sight. Rather, we should talk about love from the first smell. The first signs of falling in love start with the nose! This organ is so sensitive to a certain type of pheromones that it senses even their minimal concentrations.

More precisely, this organ recognizes not so much the smell of pheromones - since they are odorless substances - but their chemical structure. These connections have extraordinary power and cause reactions that determine this or that choice of partner.


It takes about 4 seconds to fall in love, and after a few hours the body can determine whether this person is suitable or not. Once positive signals are recognized, a chain of chemical reactions begins, the consequences of which are similar to those experienced by drug addicts after taking drugs.

A person finds himself at the so-called "high level of love". Phenylethylamine, a chemical, is responsible for shining eyes, rapid breathing, feelings of bliss, lightness, energy, unjustified joy, happiness and euphoria.

Also, thanks to this substance, a person forgets about fatigue and hunger, becomes uncritical in relation to a loved one. The response to elevated levels of phenylethylamine in the brain is an increased secretion of norepinephrine, a hormone called love substance.

Norepinephrine induces feelings of arousal, reduces appetite, improves blood circulation and makes you sensitive to touch. In addition, it raises blood pressure, speeds up the heart rate and is responsible for the delicious blush of embarrassment at the sight of a loved one.

The hormone of happiness4

In turn, high levels of norepinephrine in the brain stimulate the release of dopamine, which is called the "happiness hormone" because it is responsible for feelings of euphoria and joy. Dopamine is directly linked to the reward system responsible for the development of addiction. It is he who determines the dependence not only on drugs, but also on television, sex, food or the person we love.

It is dopamine that pushes us to look for situations and places that create a sense of satisfaction. An increase in the amount of dopamine during falling in love is closely related to a deficiency of serotonin. In turn, the lack of this neurotransmitter leads to the fact that the person feels a complete mess in his head. He is confused, he commits chaotic actions, he has trouble sleeping, he is in a mood.

The main role in these chemical processes is played by individual pheromones attributed to each specific person, which lead to the fact that it is not romantic ideals, not meaning, not taste and aesthetics that determine the fact that someone is attractive, but only the strength of his pheromones.

Probably because of this, Casanova enjoyed such great success among the fair sex. Perhaps, being a very gifted person, he knew even then that love is a chemical reaction.

Entrainment duration 5

Some neurochemical studies have shown that in people in love, the brain centers responsible for emotions resemble sparkling spots. The test was repeated after 2 years. It turned out that the love fever had subsided, because the activity of these centers had clearly decreased. Why then?

Love resembles a kind of addiction, and with each addiction there is a process of tolerance. During prolonged drug use over time, in order to achieve the same effect (that is, a feeling of euphoria and pleasure), it is necessary to supply the body with more and more of this drug so that the concentration of dopamine in the brain remains at a high level. So it is with love.

At the beginning of falling in love, phenylethylamine and dopamine induce in the body a feeling of immense pleasure, euphoria and general happiness. However, the amount of these neurotransmitters does not remain constant, tolerance develops, and over time, the level of phenylethylamine produced by the body begins to slowly but effectively decrease (its decay lasts about 2 years).

This leads to a decrease in interest in this person. All of its flaws are suddenly visible. Unlike drug addiction, we cannot increase the concentration of the brain substances responsible for falling in love (there is no equivalent - a drug), so the feeling disappears and the love goes out. And when the level of phenylethylamine drops sharply, a person unconsciously leaves to look for another object that will cause him to increase the concentration of phenylethylamine.


It is encouraging that while the person does not belong to the staunch monogamous group, even if the phenylethylamine level drops, most couples do not break up. Why? When the level of phenylethylamine in the body drops to very low levels, our body produces endorphin, a substance that is released only in the presence of a partner. It gives a sense of security and closeness.

The stability of the relationship is also provided by other substances - vasopressin and oxytocin. Oxytocin affects the longevity of relationships, makes a woman protect her children and show affection for her partner. In turn, under the influence of vasopressin, a strong bond is established between the partners, the man becomes caring towards future offspring and aggressive towards other males.

However, it should always be borne in mind that the longevity of a relationship is not only about chemistry, and it is not entirely true that love is a chemical reaction. A person, among other things, is a social being, he also needs acceptance, a sense of security and understanding, which no chemicals can provide.
