The Science of Love: Our brains ‘fall in love’ in less than a second

How long does it take for a person to fall in love?

An interesting study published by the Journal of Sexual Medicine has revealed that our brains fall in love in about one-fifth of a second.

Carried out by researchers from Geneva University Psychiatric Center, West Virginia University, and Syracuse University, the study used functional magnetic resonance imaging to see the immediate effects of love on our brains.


Their findings revealed that twelve areas of the brain work together when love strikes you. Euphoria-inducing chemicals such as oxytocin, adrenaline, dopamine, and vasopressin spread through your brain during the process.

While months of dating will make you love someone more, the study suggests that it’s at the very start that we truly realize we have fallen in love with someone. We now have scientific evidence to back up the concept of “love at first sight.”

Moreover, it was also observed that people who had just fallen in love had extremely higher levels of nerve growth factor, which plays a big role in the survival of sympathetic and sensory neurons.
