Sleepwalking causes and common triggers explained

Sleepwalking, or somnambulism, is a condition where individuals perform actions such as walking, talking, or completing daily tasks while in a state of deep sleep. While it often does not require medical treatment, it can lead to fatigue, disrupt the sleep of others, or result in dangerous activities.

Several factors can trigger sleepwalking episodes. These include stress, sleep deprivation, irregular sleep schedules, and extreme fatigue. Certain substances, such as alcohol and specific medications—including benzodiazepines, antidepressants, lithium, and some antipsychotics—can also increase risk depending on dosage and individual reaction.

Other potential triggers include migraines, particularly those with aura, and elevated body temperatures, which is especially common in children. Fever can shorten REM sleep duration and contribute to unusual dreams or nightmares. Medical consultation is recommended if episodes recur or are accompanied by other symptoms.
