Over the next week, participants wore motion sensors to bed and kept diaries detailing their sleep patterns and daily diets. The study found that 86 percent of those in the sleep-consultation group ended up spending more time in bed, and half of them slept longer: between 52 and 90 minutes longer, to be exact. That extra sleep may have been less restful, which researchers chalk up to it being a new habit. Among the control group, researchers saw no change.

According to the researchers, more than a third of U.K. adults don’t get enough sleep. In the United States, that number looks much the same: The Centers for Disease Control and Prevention (CDC) reports that one in three adults is not getting the suggested seven-hour nightly minimum. Previous research supports the theory that people who sleep for shorter stretches tend to consume more calories than long sleepers, and not getting enough sleep has also been linked to diabetes, high blood pressure, and heart disease.
