If you've been recently rescued from sleepwalking, here's a possible reason why you went zombie - lack of sleep.
Sleepwalkers should keep a regular bedtime to avoid unwanted evening strolls, said Antonio Zadra , Universite de Montreal, , who led a team that recently investigated the link between sleep loss and sleepwalking. Somnambulism, which affects up to 4 percent of adults, can cause mental confusion, bouts of amnesia and even physical injuries in those affected as they wander.
Sleepwalking is common in kids, but usually they outgrow it, says Dr. Vishesh Kapur, director of the University of Washington Sleep Disorders Center at Harborview Medical Center.
