Why banning smartphones is good for mental health

A campus that banned smartphones made its students happier. Why? Because the phones are like any other addictive substance, says Anna Lembke, author of “Dopamine Nation”: “Over time, our brains will adapt” and put us “in a dopamine deficit state…akin to a clinical depression or to an anxiety disorder. Now, we’re using this substance not to feel good or get high but just to bring ourselves back up to baseline.”
