The Science Behind Romance

Chemistry Sep 01, 2020

Have you ever stopped for a second to think that the feeling of “love” is actually a biochemical chain of events”?

Love is one of the most wonderful feelings in life. A recent discovery by Italian scientists revealed that a significant number of chemical reactions are involved in investing lust, attraction, attachment and love between couples. Scientists discovered two major hormones in the body that play an important role in both cultivating and retaining the feeling of love with their respective partner. Let’s take a look at them!

The first one is oxytocin, also known as “the cuddle hormone”. It is one of the most powerful hormones released equally by men and women. Oxytocin formulates the depth of love and forges the attachment with the partner. It also improves the interaction between couples by improving social connection.

The second one is Vasopressin, also known as an antidiuretic. It performs its operation along with the kidney and therefore controls thirst. This hormone is released in major quantity. Although the brains of women and men are structurally different, they both secrete vasopressin from the pituitary gland. Vasopressin is termed as an important hormone to promote long lasting relationships.

An article in Psychopharmacology (2012) concluded when compared to behavioral addiction, social attachment is similar— individuals become addicted to other because of the returned reward. There is a chemical chain of reaction triggered in our bodies ultimately instigating the feeling of love to strike our minds. Actually, falling in love is getting into a beautiful trap set up by nature, a natural occurrence we cannot fight. First attraction, first “sparks” in the air followed by falling in love is caused by a combination of three neurochemicals: phenyl-ethylamine, norepinephrine and dopamine. Later stages of long relationships are guided by another two: oxytocin and serotonin.

Scientists have elaborated that initial symptoms of attraction towards someone due to Adrenaline involves stress response, increase in adrenalin and cortisol and attitude reaction. Due to this, whenever you bump into your special someone, your senses decline, your heart beats like a drum, and your mouth is so dry your tongue feels like sandpaper!


Dopamine produces the effects in both male and female equally high as if they had taken cocaine or a somewhat similar drug! Dopamine is a natural stimulant providing you with ecstasy.


Last but not the least, Serotonin has been found as one of the important chemicals involved in exciting the feeling of love. Serotonin basically diverts your mind and bounds you to think about your lover and nothing else and becomes a path for the mind.
