Sleep is supposed to be a peaceful, restorative part of our day. For most of us, it’s a time when the mind and body recover from the stress and demands of daily life. But for some, sleep is not always restful. Sleepwalking, medically known as somnambulism, is a fascinating yet potentially concerning sleep disorder that affects millions of people worldwide. Though it might sound harmless or even amusing in movies, sleepwalking can sometimes be dangerous, both for the sleepwalker and others around them. In this article, we’ll explore what sleepwalking is, its causes, symptoms, risks, and strategies for management and prevention.
What is Sleepwalking?
Sleepwalking is a type of parasomnia, which refers to abnormal behaviors during sleep. People who sleepwalk typically rise from bed and walk around while still in a deep sleep. Unlike when we are awake, the sleepwalker usually has no memory of these activities when they wake up. Sleepwalking can involve simple actions, such as sitting up in bed, or more complex behaviors, like walking around the house, opening doors, or even leaving the house.
Sleepwalking episodes can last anywhere from a few seconds to more than half an hour, and the person may appear awake but remain in a sleep-like state. The behavior is more common in children than in adults, but adults can experience sleepwalking as well, sometimes linked to other health or lifestyle factors.
How Common is Sleepwalking?
Sleepwalking is relatively common, particularly in children. Studies suggest that up to 17% of children may experience at least one sleepwalking episode before the age of 12. In adults, the prevalence drops significantly, with around 4% of adults experiencing occasional sleepwalking. The condition tends to run in families, suggesting a genetic component.
Interestingly, most children who sleepwalk eventually outgrow it. Adult sleepwalking, however, may persist longer and sometimes indicate an underlying sleep disorder, medical condition, or lifestyle factor that needs attention.
Symptoms of Sleepwalking
The primary symptom of sleepwalking is, of course, walking or performing activities while asleep. However, other signs may accompany the condition, including:
- Sitting up in bed and looking around without fully waking up
- Talking incoherently during sleep
- Performing routine or unusual tasks while asleep, such as opening drawers, eating, or even driving
- Difficulty waking the person during an episode
- Confusion or disorientation upon waking
- Sleep disruption for both the sleepwalker and others in the household
It’s important to note that sleepwalkers are not usually aware of their surroundings and may appear disconnected from reality. This detachment can make certain activities dangerous if the sleepwalker leaves the safety of their home or engages in risky behaviors.
Causes of Sleepwalking
Sleepwalking occurs during the deepest stages of sleep, known as slow-wave sleep (SWS). During this stage, the body is physically relaxed, but the brain is still active. For reasons that researchers are still exploring, some people experience partial awakenings during SWS, leading to sleepwalking episodes. Multiple factors can contribute to this phenomenon:
1. Genetics
Sleepwalking often runs in families. If one or both parents sleepwalked as children, their offspring are more likely to experience the condition. Genetic studies suggest a link between specific gene variants and parasomnias, indicating that some people are naturally predisposed to sleepwalking.
2. Sleep Deprivation
Lack of sleep can trigger sleepwalking episodes, especially in adults. When the body is overly tired, the sleep cycle may be disrupted, increasing the likelihood of parasomnias like sleepwalking.
3. Stress and Anxiety
Stressful life events or chronic anxiety can interfere with the natural sleep cycle. Emotional distress can lead to more frequent awakenings during deep sleep, sometimes resulting in sleepwalking.
4. Alcohol and Medication
Alcohol, sedatives, and certain medications that affect the central nervous system may increase the risk of sleepwalking. Alcohol, for example, can disrupt the balance between deep sleep and lighter sleep stages, making partial arousal more likely.
5. Medical Conditions
Several medical conditions are associated with sleepwalking, including:
- Sleep apnea, a condition where breathing temporarily stops during sleep
- Restless leg syndrome, which can disrupt sleep and lead to arousal
- Gastroesophageal reflux disease (GERD), which can disturb deep sleep
- Fever, especially in children
6. Environmental Triggers
Sometimes, factors like noise, temperature changes, or an uncomfortable sleeping environment can provoke sleepwalking episodes, particularly in children or sensitive adults.
Risks and Dangers of Sleepwalking
While many people think of sleepwalking as harmless, it can be risky. Because sleepwalkers are not fully conscious, they may engage in behaviors that put themselves or others in danger. Some of the risks include:
- Injury: Walking into walls, tripping on objects, or falling down stairs can lead to bruises, fractures, or head injuries.
- Accidents: Sleepwalkers may attempt risky activities, such as cooking or driving, which could result in severe accidents.
- Sleep disruption: Frequent episodes can disturb the sleep of family members or roommates.
- Emotional distress: Waking up in unusual places or finding evidence of nighttime activity can cause confusion or anxiety.
- Legal or safety concerns: In rare cases, sleepwalking may lead to unintended actions with legal consequences, such as leaving the home without supervision.
How is Sleepwalking Diagnosed?
Diagnosis usually involves a combination of medical history, sleep history, and sometimes overnight sleep studies. A doctor or sleep specialist may ask questions about:
- Frequency and duration of sleepwalking episodes
- Behaviors observed during episodes
- Family history of sleep disorders
- Use of medications, alcohol, or substances
- Any underlying medical or psychiatric conditions
In some cases, a polysomnography, or sleep study, may be recommended to monitor brain waves, oxygen levels, heart rate, and movements during sleep. This can help determine whether sleepwalking is linked to other sleep disorders like sleep apnea.
Treatments for Sleepwalking
Most children who sleepwalk do not require treatment, as the condition often resolves naturally. However, adults and children with frequent or dangerous episodes may need interventions to reduce risks and improve sleep quality.
1. Lifestyle and Behavioral Approaches
- Establish a consistent sleep schedule: Going to bed and waking up at the same time each day can regulate the sleep cycle.
- Ensure adequate sleep: Sleep deprivation is a major trigger, so prioritizing rest is crucial.
- Reduce stress and anxiety: Practices like meditation, deep breathing, or yoga can lower stress levels.
- Avoid alcohol and sedatives: Limiting substances that disrupt sleep may decrease the frequency of episodes.
- Create a safe sleep environment: Remove sharp objects, lock doors and windows, and use safety gates if needed.
2. Scheduled Awakenings
For children with predictable sleepwalking patterns, parents may gently wake them 15–30 minutes before the usual time of an episode. This can disrupt the cycle enough to prevent the behavior while minimizing sleep disruption.
3. Medication
In severe or dangerous cases, doctors may prescribe medications to reduce sleepwalking episodes. These can include:
- Benzodiazepines, which promote deep sleep and reduce partial awakenings
- Antidepressants, if underlying psychiatric conditions like anxiety or depression are contributing factors
Medication is usually considered a last resort and is often combined with behavioral strategies.
4. Therapy
Cognitive-behavioral therapy (CBT) and stress management techniques can help address underlying triggers like anxiety or stress. For some adults, addressing mental health concerns can significantly reduce sleepwalking frequency.
Managing Sleepwalking in Children
Sleepwalking is most common in children aged 4 to 8. While most children outgrow the condition, parents can take steps to manage it safely:
- Keep the bedroom environment safe by removing sharp objects, covering stairs, and locking windows
- Avoid waking the child abruptly during an episode; instead, gently guide them back to bed
- Encourage a calming bedtime routine to reduce stress and anxiety
- Monitor for underlying conditions like fever, sleep apnea, or restless leg syndrome
- Document episodes to discuss with a pediatrician if they are frequent or dangerous
Tips for Adults Experiencing Sleepwalking
Adults with sleepwalking concerns should focus on both safety and overall sleep health:
- Sleep in a safe environment, ideally with doors locked and potential hazards removed
- Avoid alcohol or heavy meals before bedtime
- Establish a relaxing pre-sleep routine, such as reading or taking a warm bath
- Address sleep disorders like sleep apnea or restless leg syndrome
- Consider seeking professional evaluation if episodes are frequent, involve leaving the home, or result in injury
When to See a Doctor
Most cases of sleepwalking are benign, but it’s important to seek medical advice if:
- Sleepwalking occurs frequently and disrupts sleep
- Episodes involve dangerous activities, such as leaving the house or driving
- The sleepwalker experiences other sleep disturbances like snoring, pauses in breathing, or insomnia
- There is a sudden onset of sleepwalking in adulthood without a history in childhood
A doctor can help identify underlying causes, recommend treatment strategies, and provide guidance for safety.
Myths and Misconceptions About Sleepwalking
Sleepwalking has long been surrounded by myths. Understanding the facts can reduce fear and stigma:
- Myth: Sleepwalkers are fully awake – Sleepwalkers are not conscious and have limited awareness of their surroundings.
- Myth: You should shake a sleepwalker awake – Abruptly waking someone can cause confusion or agitation; it’s safer to gently guide them back to bed.
- Myth: Sleepwalking is rare in adults – While less common than in children, sleepwalking can persist into adulthood or even begin for the first time.
- Myth: Sleepwalkers act out their dreams – Sleepwalking occurs during deep sleep, not REM sleep when dreams are most vivid.
Coping with a Sleepwalking Family Member
Living with someone who sleepwalks can be challenging. Family members can take steps to manage episodes safely:
- Install locks or alarms on doors to prevent wandering
- Remove obstacles and hazards from common areas
- Maintain a calm approach during episodes to avoid startling the sleepwalker
- Encourage the sleepwalker to adopt healthy sleep habits and stress management techniques
- Consider consulting a sleep specialist if episodes are frequent or dangerous
Conclusion
Sleepwalking may appear amusing or mysterious, but it is a genuine sleep disorder with potential risks. Understanding its causes, symptoms, and management strategies is crucial for ensuring safety and promoting restorative sleep. Whether it occurs in children or adults, addressing lifestyle factors, stress, and sleep hygiene can often reduce the frequency of episodes. In more severe cases, professional evaluation and targeted treatment may be necessary.
Sleepwalking reminds us that sleep is a complex and delicate process. By prioritizing healthy sleep habits, managing stress, and creating a safe environment, both sleepwalkers and their families can rest easier, knowing they are taking steps to navigate this unusual but manageable sleep phenomenon.

Is sleepwalking a mental issue?
Sleepwalking is generally considered a sleep disorder rather than a mental health condition. However, it can be linked to stress, anxiety, or certain psychiatric conditions, which may trigger or worsen episodes.
What happens in the brain when sleepwalking?
During sleepwalking, parts of the brain responsible for motor control are active while areas related to awareness and consciousness remain in deep sleep. This partial awakening causes the person to move and perform actions without being fully aware.
What age does sleepwalking usually start?
Sleepwalking most commonly begins in childhood, typically between ages 4 and 8. It is more frequent in children than adults and often decreases with age.
What do sleepwalkers see?
Sleepwalkers usually have limited awareness of their surroundings. They may see vague shapes or familiar objects but cannot process them fully, which is why their movements can appear uncoordinated or confused.
Is sleepwalking linked to ADHD?
Research suggests a connection between sleep disorders, including sleepwalking, and ADHD. Children with ADHD may have disrupted sleep cycles, which can increase the likelihood of sleepwalking.
What happens if you wake a sleepwalker?
Waking a sleepwalker abruptly can cause confusion, agitation, or temporary disorientation. It’s generally safer to gently guide them back to bed rather than forcibly waking them.
Can sleepwalkers open doors?
Yes, sleepwalkers can perform complex actions like opening doors, drawers, or windows, even though they are not fully conscious of what they are doing.
Can sleepwalkers talk to you?
Sleepwalkers can sometimes talk or mumble, but their speech is often incoherent. They are usually not fully aware of conversations and may not respond logically.
Are sleepwalkers aware of their actions?
No, sleepwalkers are generally unaware of their actions during an episode and typically have little or no memory of the event upon waking.
At what age does sleepwalking stop?
Many children outgrow sleepwalking by adolescence, around ages 12 to 14. Adult sleepwalking may persist longer and sometimes requires medical attention.
What is the sleep test for sleepwalking?
A sleep study, or polysomnography, can monitor brain activity, oxygen levels, heart rate, and movements during sleep. This helps doctors identify triggers or related sleep disorders.
What medications cause sleepwalking?
Certain medications, including sedatives, hypnotics, sleep aids, and some psychiatric medications, can increase the risk of sleepwalking by affecting the brain’s sleep-wake cycle.
Why did I suddenly start sleepwalking?
