Sleep is a much-needed sanctuary from stress. In fact, researchers from the Stanford Sleep Epidemiology Research Center found that people with sleep disorders such as sleep apnea are five times more likely to experience depression than those who sleep soundly. "Individuals with sleep apnea generally have a sleep efficiency between 65 and 85 percent," says Maurice M. Ohayon, M.D., Ph.D., the center's director and the study's lead researcher.
