Chemistry of Love


Brain doing the analysis :

When do you know if you fancy someone? What does love do to your brain chemicals, and is falling in love just nature's way to keep our species alive?

We call it love. It feels like love. But the most exhilarating of all human emotions is probably nature’s beautiful way of keeping the human species alive and reproducing.

With an irresistible cocktail of chemicals, our brain entices us to fall in love. We believe we’re choosing a partner. But we may merely be the happy victims of nature’s lovely plan.

It’s not what you say...

Psychologists have shown it takes between 90 seconds and 4 minutes to decide if you fancy someone.

Research has shown this has little to do with what is said, rather

  • 55% is through body language

  • 38% is the tone and speed of their voice

  • Only 7% is through what they say


We always talked about LOVE based on EMOTION..but it also explainable in SCIENTIFIC - narrow down to our own body chemical reaction.

Based on FACTS!!

The 3 stages of love

Helen Fisher of Rutgers University in the States has proposed 3 stages of love – lust, attraction and attachment. Each stage might be driven by different hormones and chemicals.

Stage 1: Lust

This is the first stage of love and is driven by the sex hormones testosterone and estrogen – in both men and women.

Stage 2: Attraction

This is the amazing time when you are truly love-struck and can think of little else. Scientists think that three main neurotransmitters are involved in this stage; adrenaline, dopamine and serotonin.


The initial stages of falling for someone activates your stress response, increasing your blood levels of adrenalin and cortisol. This has the charming effect that when you unexpectedly bump into your new love, you start to sweat, your heart races and your mouth goes dry.


Helen Fisher asked newly ‘love struck’ couples to have their brains examined and discovered they have high levels of the neurotransmitter dopamine. This chemical stimulates ‘desire and reward’ by triggering an intense rush of pleasure. It has the same effect on the brain as taking cocaine!

Fisher suggests “couples often show the signs of surging dopamine: increased energy, less need for sleep or food, focused attention and exquisite delight in smallest details of this novel relationship” .


And finally, serotonin. One of love's most important chemicals that may explain why when you’re falling in love, your new lover keeps popping into your thoughts.

Stage 3: Attachment

Attachment is the bond that keeps couples together long enough for them to have and raise children. Scientists think there might be two major hormones involved in this feeling of attachment; oxytocin and vasopressin.

Oxytocin - The cuddle hormone

It promotes the need to be physically held, have close contact with he mate and makes both the sexes more caring. It can be released simply by a lover’s look, smell or even a fantasy.


So much for the chemistry of infatuation. When infatuation subsides, another chemical takes over, which is responsible for intimate relationships. These chemicals are created by endorphins. They make a relationship steadier, intimate, dependable, warm and a great sharing experience. They do not induce a giddy high, but calmness and stability…hence are the reason why people stay married. The longer they are married, the longer two people stay together, because this chemical is addictive. It is endorphins that trigger grief on a spouse’s death or long separation, those yearnings for togetherness.



We can blame our chemicals for everything. We had a list of attributes ready for matching, but we just end up falling in love with the person who possesses none of them…it is , as they say, chemistry. It is the facts! ;D
