Oh, the Passion! A sensation that few know how to describe, but easy to see.
This happens because when we are passionate a series of chemical reactions are triggered in our body, making us happier and less stressed.
A study coordinated by American biological anthropologist Helen Fischer at RutgersUniversityidentified that different hormones are linked to three moments of the novel: Desire, attraction/conquest and bonding.
In the first moment, desire is characterized by sexuality. Based on evolution, it is understood as the necessity (instinct) of the human being to reproduce.
Therefore, in this phase are released the sex hormones: testosterone and estrogen.
In attraction/conquest, there is already the sensation of ?reward?, with the release of dopamine, which is related to well-being. Spending more time with Crush, in most cases, generates this satisfaction.
Ailton Amelio da Silva, professor at the Institute of Psychology at the University of São Paulo, says that passion is a ?state of mind?, but not all people feel.
?The passion is wonderful. The person you feel is hallucinated, like you?re numbing. It changes the mood, the person gets up, the days become more beautiful, she hears music with more feelings. There is what we call intrusive thoughts in her can think of the other all day. He also loses his appetite, sometimes he loses his sleep. ?
The lack of appetite and insomnia are directly related to the production of another hormone, the neuroepinephrine, which makes us more euphoric and willing.
?This phase can last for months, but it is very much based on the idealization of the other. As you contact [with the person], it tends to break down. It can become love or it can become nothing, ?he adds.
The third phase, which relates to the connection, the more prolonged involvement and the relationship itself has the release of oxytocin and vasopressin more present.
Oxytocin, also called love hormone, is released with hugs, kisses and sexual intercourse.
When you are close to your partner or partner, the body produces more oxytocin, decreasing cortisol levels, which causes stress.
Namely, the mere fact of having the crush around on this Valentine?s Day can reduce the level of stress.
In addition, oxytocin is responsible for generating a sense of safety and the feeling of attachment that makes couples feel closer after sex.
Vasopressin is another hormone that stands out in the organisms of couples who love each other. However, this substance is more linked to behavior that produces long-term monogamous relationships.
According to experts from the Institute of Neuroscience at Harvard University, the difference between oxytocin and vasopressin is associated with the fact that the passion tends to decrease as the attachment grows.
Another study coordinated by Helen Fischer, conducted in 2005, analyzed MRI images of the brain of 17 people who identified themselves as passionate.
The researchers identified that the participants who looked at the photo of the person they were passionate about activated two areas of the brain associated with dopamine: the salamander nucleus and the ventral tegmental area .
Despite this, excess of oxytocin and dopamine can lead to harmful behaviors to the relationship, such as jealousy, adulterians, irrational behaviors and drug abuse.
Psychiatrists Richard Schartz and jacquelina Olds, Harvard Medical School professors, evaluate in an article that there are inevitable changes in love over time.
Passionate love gives space to a deeper love, but not as euphoric as the one experienced during the early stages of the novel.
In 2011, Helen Fischer attended a study at Stony Brook University in new York City, who discovered that it is possible to be madly in love with someone even after decades of marriage.
Magnetic resonance imaging was performed in couples who were together about 21 years ago, on average.
The result was surprising. Areas in the brain were found to be rich in dopamine at the same intensity as in couples who had been together for a short time.
The conclusion was that the emotion of the novel may remain while the apprehension of the relationship is left aside.
Reascender the ?Fire of passion? in longer relationships is nothing more than to increase the levels of oxytocin through sexual activity, evaluate the researchers.
