The first, lust, is driven by the levels of testosterone (men) and oestrogen (women) in our bodies. There are 3 distinct phases of falling in love. The initial happy feelings of being in love is stimulated by 3 chemicals in the brain: noradrenaline that stimulates adrenaline production causing that racing heart and sweaty palms dopamine, the feel-good chemical and phenylethylamine that is released when we’re near our crush, giving us butterflies in our tummies.īut is there a biological reason behind these feelings? And why do you fall in love with that one person you do? As time passes, this initial bust of feeling often fades into a comfortable closeness.


We talk about the moment of falling in love as if we have been hit by Cupid’s arrow – it is intense, overwhelming, sometimes fast and can feel like fate.
