Love neurobiology

Humans can experience confusion due to the neurobiology of love that always seems to try to put us to the test, between what we want and what we know is the most convenient for us.

Love and desire

Can you feel a strong attachment towards a person for a long time, while feeling an intense romantic love for another that makes you sigh and takes your sleep away, but you can also experience sexual desire towards other people ... Well we are able to feel interest and attraction for more than one person at the same time, due to our brain biology. Therefore, to maintain a long-term relationship it is a good resource to make the daily decision of focus our attention and energy on that special person, instead of looking for other attractive options in several ways for us, which can lead us to separation, and to divorce, which are emotionally difficult events.

How love develops in our brain

So, if you've been through any infidelity or you are spawning it deep within your brain ... It is important that you know that it is responsible, in large part, for the neurobiology of love, this will help you remove some unnecessary faults and focus on working with the aspects that are in your hands, so that your relationship is more satisfying, healthy and happy, understanding our biology can help you a little.

1. The sex drive

It is the wish that look for gratification and satisfy yourself to itself, it mainly produces: dopamine, endorphins, norepinephrine and adrenaline, those who make our judgment literally clouded; Therefore, some potential dangers are often ignored. At this point, norepinephrine gives us the energy to be with the couple doing many activities, orients our behavior towards a goal, is when it takes our sleep, attention is fixed on that special person and that impulse seeks to eliminate obstacles to satisfy their desires .

2. Romantic love

It's the desire and the motivation that arise from being with that special person, not only in the sexual aspect. Dopamine is also associated here, among other neurotransmitters; because during sex and with orgasm the oxytocin and vasopressin, producing the feeling of bond and connection with the other person. As for casual sex, it can result in a crush, even if you have not had that idea in mind, weakening the bond of our stable relationship if there is one. According Helen Fisher, romantic love is an impulse that makes us crave, and may even be more powerful than sexual desire, reached this conclusion, taking data from the research he has done in these years, based on neurosciences and anthropology, mainly.

During a state of sexual arousal and orgasm, the frontal lobe areas are inhibited, so we reflect less What we do, can lead us to decrease our critical capacity, due to prefrontal hypoactivity. This can lead us to make inconvenient decisions for us, we can even fall into irresponsible behavior with negative effects for ourselves and for our relationship.

3. Attachment to a long-term partner

It consists in the search for the sensation of calm and security that you can feel with a lasting partner. Some experts like Helen Fisher, say that romantic love evolved to allow us to focus our mating energy on a single person and thus conserve time and energy for other activities suitable for our evolution and that of our species; in turn, he affirms that attachment evolved to allow us to tolerate that human being called a couple, at least long enough to raise a child together.

At this stage, it is very important to take care of our relationship, strengthening the bond through our actions, generally at this stage we know what pleases and not our partner, so that we can build an environment of greater mutual understanding and show greater empathy; the have interests and hobbies in common how children, projects, goals, desires, and dreams foster union.

Love which implies accompaniment, is what many couples see as the natural progression of a successful relationship, but it can be an unnecessary commitment. "Couples must fight for love with all the ornaments," and couples who have been together for a long time and want to regain their romantic advantage should know that it is an attainable goal that, like most good things in life, requires energy and devotion", according to Acevedo research.

There comes a time when testosterone levels in men go down and those in women go up a bit, which allows them to live more easily.

Try to always keep in mind why you chose that person and what he did and he has made it unique and special for you all this time ... "You are in love when you realize that another person is unique" (Borges). Why do we fall in love with one person instead of another? For several reasons, such as context, proximity, mystery, coupled with a list of qualities that we put to our platonic love, usually during childhood. In this way looking for people with complementary brain systems to ours. We can learn to love better and use our differences to complement each other better.

"Love can evoke very strong emotions in the human being, infidelity can lead to generate negative emotions with consequences of moderate to severe, but when love endures and there is a will, it can heal that relationship through forgiveness."
