Sleepwalking is a common phenomenon that occurs during the deepest stage of non-REM sleep. Sleepwalkers are able to perform basic tasks and can sometimes engage in more complex activities like cooking or driving. The exact causes of sleepwalking are not fully understood, but factors such as stress, sleep disorders, and sedatives can increase the likelihood. Treatment options include promoting healthy sleep habits, implementing safety measures, and considering medication if necessary. If encountering a sleepwalker, it is best to gently guide them back to bed and ensure their safety until the episode resolves.
