Yup, sleeping in is bad for you. A new study published in EurekAlert! says going to bed and waking up later on the weekends than during the week -- which they call “social jet lag” -- is associated with poorer health, worse mood and increased sleepiness and fatigue.
American Academy of Sleep Medicine researchers report each hour of “social jet lag” increases the likelihood of heart disease by 11 percent.
The study’s scientists recommend adults get 7 or more hours of sleep every single day, including the weekend.
