When we fall in love so many “strange” things occur within us, we ask ourselves so many questions, we even generate such cataclysms (abandonment of family, of friendships, trips to the end of the world to be with the beloved person …) that Science has not I could do something other than investigate. We present 7 scientific facts about love, tested and certified by this “infallible” method called Scientific Method …
Numerous researchers around the world take blood tests, measure the pulse and compare the behavior of people, in order to explain what love is from the scientific point of view. We have collected some recently tested hypotheses about the mechanism of this eternal sense.
01 Love is like cocaine
The onset of falling in love has almost the same effect on the human body as a dose of cocaine. The brain tomography of a lover reveals that the area that responds to motivation is saturated with dopamine, a substance that appears in the blood to feel pleasant sensations such as having sex, eating chocolate or that appears when taking drugs.
Such is the similarity that many musicians have played with the ambiguity in the lyrics of their songs without us being really clear if they are talking about drugs or a passionate love.
02 Love is a method to survive
In his book ‘Viaje al amor’, Eduardo Punset, the leading science disseminator in Spain, affirms that even though love is considered an act of generosity, in reality it is a consideration of services in order to survive. According to the expert, love is an “evolutionary instinct of fusion with another organism”, which appeared in the living world before sexual differentiation. “Without love there is no life,” he says.
03 Love appears in an instant
Scientists say that to fall in love, one takes only one fifth of a second. At this time, twelve areas of the brain release substances together – such as noradrenaline, dopamine, oxytocin, vasopressin – that generate this pleasant state. These hormones make us lose our heads, and besides, as everything happens in an instant, they leave us without time to think about what we do or what we feel.
04 Love is blind (but hear well)
Noradrenaline and dopamine work in those areas of the cerebral cortex associated with the analysis of information received from outside, in particular, visual and auditory information. While the latter intensifies the ear of lovers, the former distorts visual perception. The experiments were also proved in the figurative sense of this saying: the British A. Bartels and S. Zeki showed that the areas associated with negative emotions tend to be reduced in lovers, and pleasure centers are activated (see number 01), making forget all the negative.
05 Love lasts 4 years
According to established theories, an approximate term of four years has its biological reason: in the remote times, in this way the father could protect the mother and the child in the period of greatest vulnerability: that of pregnancy and lactation (see number 2). ). The Canadian anthropologist Helen Fisher, who studied various cultures and tribes, found the tendencies of having children every four years and separated after four years of marriage, which shows that love relationships are determined with a basic reproductive cycle.
06 Fidelity depends on the genes
Researchers at Binghamton University, USA UU., Revealed that a mutation in a certain gene is associated with promiscuity, infidelity and the adventures of a night. This gene is linked to a dopamine receptor, the pleasure hormone. However, scientists warn that not everyone who has this genotype is inclined to infidelity, and the study can in no way exonerate sinners.
07 Men, more addicted to having sex than women
This fact has surely surprised you, right? The famous American psychiatrist Louann Brizendine states in her book ‘The male brain’ that men think more about physical contact than women. According to the expert, the male brain area dedicated to sexual search is 2.5 times larger than theirs. So, they have more sexual fantasies and in general they think about this issue three times more than the females.
And now that Science has spoken, I ask you that if at this moment you are not sure that you have ever been. What do you think of all this?
Is Love the same as survival instinct? Are the hormones that make us feel happy or be next to the person we love that makes us secrete those hormones? Where does all this leave the love between people of the same gender who evidently can not reproduce?
These are the problems faced by the scientific method that by definition can only work on measurable facts to elaborate its hypotheses and reach conclusions.
Do you believe that in Love not everything can be measured and therefore can not be explained scientifically?
