Scientists are studying how Facebook cause the human nervous system to release a “cuddly” chemical that is linked with all kinds of feel-good emotions.

Engaging in all that Facebook has to offer involving psychological support seems to spike our brains with the cuddle hormone called oxytocin,which explains why so many of us are addicted to the social networking site. The effect that the hormone has on a person is like falling in love. The feeling reportedly produces a calming effect that envelops and leaves us feeling cuddled and interpersonally connected to what we’re doing on the social network.

Oxytocin receptors are located in the brain’s amygdala. The hormone is heightened in a variety of behaviors that involve people connecting with one another.
