The Scary Health Condition Sleeping Too Long Can Signal

There’s nothing better than sleeping in, right? But sleeping for too long might be signaling something serious about your brain health, researchers from Boston University School of Medicine suggest.

In the study, people who slept for more than 9 hours a night were twice as likely to develop dementia of any kind over a 10-year follow up than those who snoozed between 6 to 9 hours nightly. They were also 71 percent more likely to develop Alzheimer’s disease.
