According to a 2016 study, more than a third of American adults don’t get the recommended minimum seven hours of sleep per night. If you’re included in that group, you’ve likely heard (and tried) many tricks to get a better sleep: Follow a set sleep schedule. Drink sleep-inducing tea. Turn on a white noise machine.

Case in point: These seven common mistakes can stand between you and the sleep your body needs. Take note of each for a restful night’s sleep.
