The chemistry of love, why do we fall?

When we fall we are more beautiful, we are happier and the world seems nicer. And that great feeling, love, is one of the most wonderful feeling in the world. Who has not ever been in love? Your symptoms are unmistakable: knot in the stomach, happiness, insomnia, poor appetite, rapid pulse at the sight of the lover ... But do we have so clear why we fall in love? It is simply a matter chemistry.

Those who clung to the idea of ​​Cupid's arrows and the romantic vision of love, know that this is not anything other than biochemistry. A single burst of hormones! Falling in love causes a chain of chemical reactions are activated and appear like behavior of love. This is how thousands of neurons send electrical shocks to the brain that trigger the expulsion of hormones, which buoyed the passion, fidelity or infatuation.

One of the first hormone we secrete when we fall in love is the feniltelitamina, (family of amphetamines) that is responsible for the passion, the euphoria and blindness - when we think that other person is perfect - love itself. Norepinephrine and serotonin are what make us the heart to speed up when the beloved.

Dopamine is the hormone of pleasure and reward. It is present at the beginning of relationships and is what causes the sex drive. Is secreted through orgasm and gives us feelings of happiness.

But the months after the body ceases to secrete dopamine, since it can not assume it in large quantities and when it appears oxytocin, also called the love hormone. It is responsible for monogamy and essential part of the design (is secreted during orgasm, pregnancy and childbirth) and close ties between the couple or between mothers and their newborns. Those animals that secrete more oxytocin are monogamous, while those less polygamous.

Fortunately or unfortunately, these chemical reactions are addictive, so when we leave and stop segregate, we have withdrawal symptoms, as with drugs - hence the intense pain and sadness after a breakup.

Still, education, social environment or its own staff time each, are important when it comes to love. Search for love? If so, rent apartments in Venice and spent a few days in the city of lovers.
