Sleepwalking: Understanding Somnambulism in Adults

Sleepwalking isn't just a childhood phenomenon—it affects adults too. Walking, talking, or performing complex activities while asleep can be confusing and sometimes dangerous. Learn about the causes, risks, and effective management strategies for adult sleepwalking.
What Is Sleepwalking?
Sleepwalking, or somnambulism, is a parasomnia that occurs during deep non-REM sleep. The person may sit up, walk around, or perform complex behaviors while remaining asleep and having no memory of the event upon waking.
While commonly associated with children, approximately 1-4% of adults experience sleepwalking episodes. Unlike children who typically outgrow it, adult-onset sleepwalking often has underlying causes that need to be addressed.
Key Facts About Sleepwalking:
- •Usually occurs during the first third of the night during deep sleep
- •Episodes can last from a few seconds to 30 minutes or longer
- •The sleepwalker typically has no memory of the event
- •Eyes are usually open but with a glassy, unfocused appearance
- •Attempting to wake a sleepwalker can cause confusion and disorientation
Common Sleepwalking Behaviors
Sleepwalking behaviors range from simple to complex activities, and understanding these can help identify episodes.
Simple Behaviors
Sitting up in bed, looking around, walking around the room, or going to the bathroom without full awareness.
Complex Behaviors
Getting dressed, cooking, eating, driving, or even leaving the house while still asleep.
Sleep-Related Eating
Eating or preparing food during sleep episodes, sometimes consuming unusual or inedible items.
Violent Behaviors
In rare cases, aggressive or violent actions may occur if the sleepwalker feels threatened or is forcibly awakened.
Causes and Triggers
Several factors can cause or trigger sleepwalking episodes in adults.
Sleep Deprivation
Insufficient sleep is one of the most common triggers, as it increases time spent in deep sleep.
Stress and Anxiety
Emotional stress, anxiety disorders, and PTSD can significantly increase sleepwalking episodes.
Medications
Certain sedatives, hypnotics, psychiatric medications, and antihistamines can trigger sleepwalking.
Alcohol and Substances
Alcohol consumption and certain recreational substances can disrupt sleep architecture and trigger episodes.
Sleep Disorders
Conditions like sleep apnea, restless leg syndrome, and other sleep disorders can contribute to sleepwalking.
Medical Conditions
Fever, gastroesophageal reflux, migraines, and certain neurological conditions can trigger episodes.
Risk Factors
Certain factors increase the likelihood of experiencing sleepwalking episodes.
- •Family history of sleepwalking (genetic predisposition)
- •History of sleepwalking during childhood
- •Irregular sleep schedules or shift work
- •High levels of ongoing stress
- •Use of certain medications
- •Sleeping in unfamiliar environments

Driving
In extreme cases, people have driven vehicles while sleepwalking, posing serious risks to themselves and others.
Relationship Issues
