What Is Sleepwalking?

Sleepwalking, or somnambulism, is a type of sleep disorder where a person walks or performs complex behaviors while not fully awake. It typically occurs during deep sleep, most commonly in children but can affect adults too. While often harmless, sleepwalking can pose safety risks and be linked to underlying conditions.

Who Is Affected by Sleepwalking?

Sleepwalking can affect people of all ages, though it’s most prevalent in children aged 4 to 8. It often runs in families and may occur occasionally or regularly. While many outgrow it, adult sleepwalking may indicate stress, sleep disorders, or other health issues that deserve attention.

Possible Causes

What Might Trigger Sleepwalking

Several internal and external factors can increase the likelihood of sleepwalking episodes. Recognizing these triggers can help you or your loved ones reduce occurrences and stay safe.

Sleep Deprivation

Lack of adequate rest disrupts normal sleep cycles and may trigger episodes.

Stress and Anxiety

Emotional distress can interfere with deep sleep and lead to nighttime walking.

Alcohol or Medication

Certain substances affect brain activity during sleep and contribute to sleepwalking.

Fever or Illness

High temperatures or infections can disrupt sleep in children, increasing the risk.

Irregular Sleep

Inconsistent bedtime routines confuse the body’s natural rhythms.

Genetics

A family history of sleepwalking makes it more likely in both children and adults.

"Generally sleepwalking is pretty harmless, but it can occasionally result in injury to the sleepwalker or possibly those close to them, and for some people, it can be a big problem.”

Clinical Psychologist & Sleep Researcher

"20% of children and 2-3% of adults have some form of abnormal night-time behaviour although many people do not go to their GP about this. Often simple advice and time is all that is needed."
