If you experience moments of fear or extreme excitement with someone, it is likely that both of you will fall in love with each other as the simultaneous release of adrenaline in both partners may give a feeling of falling in love.
Dopamine is a brain chemical that gets released in your brain while you are in love giving you the feeling of intense pleasure. This is the same chemical that gets released when you take opioid drugs like cocaine and this goes a long way in explaining how love can be addictive!
When you are in love, the frontal cortex of your brain responsible for judgement shuts down according to MRI scans. This explains why people are often accused of losing their mind and not thinking practically when they are in love.
It has well been documented that love doesn’t just make you happy, but sad too. What happens is that the rise in dopamine during love makes the serotonin levels in your body drop. This chemical is responsible for regulating your mood and appetite and a significant drop can make you feel anxious and jittery. Scientists have found that this drop in serotonin levels during love can be as intense as that seen in people with obsessive compulsive disorder.
While poets and writers may have their own explanations of what happens in love, scientists have actually used scanning technology to reveal what happens to your brain when you are in love. And the results are interesting, to say the least.
