Older adults with irregular sleep habits may face a higher risk for hardened arteries than their peers with regular bedtimes and hours of sleep, new research suggests.
The study, published Wednesday in the Journal of the American Heart Association, found adults 45 and older who fell asleep at different times each night and slept an inconsistent number of hours were more likely to develop atherosclerosis, a buildup of plaque in artery walls that can lead to a heart attack or stroke.
