This Sleep Disorder Is a Legit Medical Diagnosis for Being an Extreme Night Owl

Delayed sleep-wake phase disorder pushes your bedtime by two or more hours, no matter how early you go to bed, reports Shape.

“DSWPD occurs when sleep onset and final awakening are delayed with respect to the desired clock time,” explains Eve Van Cauter, Ph.D., chair of Sleep Number‘s scientific advisory board, and professor in the department of medicine at the University of Chicago. “Typically, the affected individual falls asleep and awakens two or more hours beyond the socially acceptable or conventional bedtime,” she says.
