What effect does social media have on people? There’s plenty of research concluding Facebook makes us unhappy — and the longer that we spend on it, the unhappier, more depressed, anxious, angry, jealous we get. Conversely, if we take a break, our happiness soon rebounds. We can probably surmise that most social media, Twitter, Snap, whatever, has a similar effect. It reduces people’s social and emotional well-being pretty sharply and immediately.
