There’s nothing like tucking yourself into bed and watching Game of Thrones on your iPad before you hit the hay. But now your head is reeling with thoughts of Cersei, Daenerys and Jon Snow. (Spoiler alert: Actually falling asleep is probably a long ways off.)
Here’s why: According to a new study in the Journal of Clinical Sleep Medicine, binge-watching before bed can have a major impact on sleep quality and cause insomnia to worsen, which leads to fatigue the next day.
But it’s not just because you’re staying up past your bedtime. The number of episodes you watch and the type of content you’re viewing are both factors in the quality of the shut-eye you log. Think about it: If you’re emotionally invested in a show (say, Game of Thrones), you’re going to be extra alert when the final credits roll, as opposed to when you watch something that’s much more chill that you can check in and out of (like The Great British Bake Off).
Bottom line: Your bedtime routine should be sacred. If you’re going to binge, try to spread those GOT episodes out. (Hey, isn’t it more fun that way?)
