Sleep disorders

10 to 15 percent of adults complain of insomnia-recurring problems in falling or staying asleep.
People who suffer narcolepsy experience uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, at inopportune times.
Another sleep disorder-sleep apnea- leaves millions of people by temporary cessations of breathing during sleep and repeated momentary awakenings.
Unlike sleep apnea, night terrors target mostly children, by high arousal and being terrified; unlike nightmares, night terrors occur during Stage 4 sleep, withing two or three hours of falling asleep, and seldom remembered.
