Did you know:
864 million people use Facebook on a daily basis? Or that the time spent on Facebook per user per day is more than twenty minutes?
What’s very interesting is that much of the success of Facebook can be attributed to brain chemistry. The way Facebook is set up triggers the release of dopamine, a brain chemical that is linked to pleasurable feelings of reward, and also oxytocin, the “love hormone” that helps us feel close to people we care about.
One of the things about Facebook that releases the feel-good chemical dopamine in our brains is simply looking at pictures of attractive people. And because these people are usually folks that we know and care about, it can also increase the release of oxytocin.
