Turns out your brain might be fooling you into thinking that browsing Facebook is you doing something incredibly creative and productive that will improve your life.
According to scientists in Milan and M.I.T., they examined the physiological states of 30 people using Facebook compared to them relaxing looking at natural panoramas or taking a math test and measured both the physical and psychological responses.
They included breathing rate, brain activation, pupil dilation and found the when people looked at Facebook, the study subjects were transported into a "core flow state", which is what you might experience when you are practicing for something, or doing something important.
Mihaly Csikszentmihalyi describes it wonderfully in this TED talk.
We already know Facebook is harder to resist than cigarettes and alcohol. So it's not all that surprising that Facebook is enjoyable. Cocaine is enjoyable! But like an addictive drug, the results suggest the social network might have a sinister effect: Facebook makes you think you're being productive when really you're probably just telling everyone how delicious your lunch was and discovering that your best friend's cousin's baby just ate squash.
So if its like a drug, then you might want to consider this: Harvard's Daniel Gulati said: over time, Facebook is making us miserable. And its probably true if you don't get out often enough to get some real life interaction done.
