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.
Love has 3 stages, as described by Helen Fisher of Rutgers University in the States: 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 oestrogen – 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.
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.
