The Science of Love: Why We Fall in Love
Falling in love causes your body to release a flood of feel-good chemicals that trigger specific reactions. This is responsible for making your cheeks flush, your palms sweaty and your heart race.
Levels of dopamine, adrenaline and norepinephrine increase when two people fall in love. Dopamine creates feelings of euphoria while adrenaline and norepinephrine are responsible for the pitter patter of the heart, restlessness and overall feelings of being in love.
MRI scans indicate that love lights up the pleasure center of the brain. When you fall in love, blood flow increases to the area which is the same part of the brain that is implicated in obsessive compulsive disorders. So, maybe there really is a science behind falling “head over heels” in love.
