Newsweek asks: what exactly happens, biologically, if you habitually binge Netflix instead of getting enough sleep or doing something else, like reading a book or going outside?

Binge-watching can have harmful effects on your body and sleep cycle. And, interestingly, a recent study indicated that binge-watching a single show has a more profoundly negative effect on your sleep quality than watching the same number of episodes of different shows. That means there’s something particularly harmful about the Netflix model, which encourages you to “turn your brain off” and speed-watch a series in a single evening.
