6 You're In Love Explained By Science

Previously, here at Canaltech, we even highlighted what science says about love, that is, how your body reacts to this feeling. However, it’s also worth keeping an eye out for certain signs, which may suggest that you’re in love with someone.

According to an article published in the journal Journal of Personality and Social Psychologypeople in love focus on events and objects that awaken the person’s memories, and carry out quick and frequent daydreams about shared moments and memories.

A study published in 2013 in the journal Motivation and Emotion suggests that being in love prevents people from focusing on other information. The idea is that this focused attention results from elevated levels of central dopamine, as well as a spike in central norepinephrine, a chemical associated with increased memory in the presence of new stimuli.

Meanwhile, an article published in the journal Philosophy, Psychiatry and Psychology suggests that when people in love see pictures of that special someone, it activates the same brain regions that are activated when using a drug. This means that being in love is a form of addiction and when that is taken away, there can be relapses.

intrusive thoughts

People in love spend, on average, more than 85% of their day thinking about their loved one, which could be a result of decreased levels of central serotonin in the brain, a condition that has been linked to obsessive behavior in the past.

People in love often arouse a sense of empathy towards their loved one, feeling the other’s pain as if it were their own. Scientists found significant patterns in the brain activity of people who were in love: their mirror neurons, which are linked to feelings of empathy, were more active, particularly in a long-term love relationship.

interests aligned

Also, being in love can result in changes in daily priorities to align with those of the loved one. According to a study presented at the conference Being Human, people with testosterone-dominant personalities (competitive and emotionally restrained) are often attracted to partners with personalities linked to high levels of estrogen and oxytocin (people who tend to be empathetic, caring, and sociable).


Another sign that you are in love with someone is the feeling of possessiveness. According to Indian Journal of Endocrinology and Metabolism, oxytocin is released during sexual activity. This hormone creates social bonds and develops trust, in addition to being responsible for desire and making the suitor reject other people. This behavior evolved as a biological necessity, allowing people in romantic relationships to focus mating energy on a particular individual.
