What exactly happens to the brain when we are in love?
When we’re falling in love with someone, the first thing we notice is how good it feels. It’s because the brain releases feel-good neurotransmitters that boost our mood. When we find love, it is like biolog ical fireworks. Our heart rate is elevated, our levels of the so-called love hormone oxytocin are rising, which makes us feel connected. Our levels of the hormone and neurotransmitter norepinephrine are spiking, which makes us lose track of time; our levels of adrenaline rise, which expands the capillaries in our cheeks and makes us flush.
