Adult Sleepwalking: Is It Dangerous and How Do You Stop It?

Sleepwalking (also called somnambulism) is often thought of as a childhood problem. But adults can experience sleepwalking too—and when they do, it tends to raise more concern. If you or someone you love is sleepwalking, you may be wondering: Is this dangerous? Why is it happening? And how can it be stopped?

Here's what you need to know, based on established medical research and sleep medicine guidelines.

What Is Sleepwalking?

Sleepwalking is a type of sleep disorder called a parasomnia. It happens during deep non-REM sleep, usually in the first third of the night. During an episode, a person may:

• Sit up in bed
• Walk around the house
• Talk or mumble
• Perform routine behaviors (like dressing or moving objects)
• Have a blank stare
• Be difficult to wake
• Have no memory of the episode the next morning

Sleepwalking is not the same as acting out dreams (which usually occurs during REM sleep). Instead, it happens when the brain is partly asleep and partly awake.

How Common Is Sleepwalking in Adults?

Sleepwalking is more common in children, especially between ages 4 and 12. Many children outgrow it.

In adults, it's less common—affecting roughly 1–4% of the population. However, adult sleepwalking deserves more attention because it is more likely to:

• Be linked to other medical or mental health conditions
• Be triggered by medications
• Result in injury

---

Is Adult Sleepwalking Dangerous?

Sleepwalking itself is not usually life-threatening. However, it can become dangerous, especially if episodes are frequent or intense.

Potential Risks Include:

• Falling down stairs
• Leaving the house
• Driving a car while asleep (rare but documented)
• Using sharp objects
• Accidental self-injury
• Injury to others (unintentionally)

Most people who sleepwalk are not violent. But because they are not fully aware, their coordination and judgment are impaired.

If sleepwalking leads to injuries, risky behaviors, or episodes outside the home, it becomes a serious safety issue that should be addressed promptly.

What Causes Sleepwalking in Adults?

Sleepwalking happens when the brain has difficulty transitioning smoothly between sleep stages. Several factors can increase the risk.

Common Triggers and Causes

1. Sleep Deprivation
Lack of sleep is one of the biggest triggers. When you're overtired, your brain may enter deeper sleep more abruptly, increasing the risk of partial awakenings.

2. Stress and Anxiety
Emotional stress can disrupt normal sleep cycles and increase parasomnias like sleepwalking.

3. Alcohol Use
Alcohol interferes with sleep structure and can increase episodes.

4. Medications
Some medications are associated with sleepwalking, including:

• Sedatives
• Sleep medications
• Certain antidepressants
• Some antipsychotics

5. Other Sleep Disorders
Conditions such as:

• Obstructive sleep apnea
• Restless legs syndrome
• Periodic limb movement disorder

These may trigger repeated partial awakenings.

6. Genetics
Sleepwalking often runs in families. If a parent sleepwalked, the risk is higher.

7. Medical or Neurological Conditions
Rarely, adult-onset sleepwalking may be linked to:

• Seizure disorders
• Brain injury
• Migraines
• Fever
• Thyroid disorders

If sleepwalking starts suddenly in adulthood without a childhood history, it's especially important to evaluate for underlying causes.

When Should You Be Concerned?

Occasional mild sleepwalking without injury is usually not an emergency. However, you should speak to a doctor promptly if:

• Episodes are frequent
• There has been an injury
• The person leaves the home
• There are violent movements
• Sleepwalking begins suddenly in adulthood
• There are signs of seizures (jerking, confusion after waking)
• There are breathing pauses during sleep (possible sleep apnea)

Some conditions that mimic sleepwalking—such as nighttime seizures—can be serious. A medical evaluation helps rule out dangerous causes.

How Is Sleepwalking Diagnosed?

Doctors usually diagnose sleepwalking based on:

• A detailed medical history
• Description of episodes (often from a bed partner)
• Review of medications
• Evaluation for sleep deprivation or stress

In some cases, a doctor may recommend:

• A sleep study (polysomnography)
• An EEG to rule out seizures
• Screening for sleep apnea

Diagnosis is especially important when episodes are new, severe, or unusual.

---

How Do You Stop Sleepwalking?

Treatment depends on the cause. Many adults can significantly reduce or stop sleepwalking by addressing triggers.

1. Improve Sleep Hygiene

This is often the first and most effective step.

• Go to bed and wake up at the same time daily
• Aim for 7–9 hours of sleep
• Avoid screens before bed
• Keep the bedroom dark and quiet
• Avoid caffeine late in the day

Consistent, high-quality sleep reduces deep sleep instability.

---

2. Reduce Stress

Stress management can significantly decrease episodes.

Helpful strategies include:

• Regular exercise (not right before bed)
• Deep breathing exercises
• Meditation
• Cognitive behavioral therapy (CBT)
• Journaling before bedtime

---

3. Limit Alcohol

Alcohol disrupts sleep cycles and increases parasomnias. Reducing or eliminating alcohol often improves symptoms.

---

4. Review Medications

If sleepwalking began after starting a medication, speak to your doctor. Do not stop medication on your own. Your doctor may adjust the dose or switch medications safely.

---

5. Treat Underlying Sleep Disorders

If sleep apnea or restless legs syndrome is present, treating those conditions often improves sleepwalking.

For example:

• CPAP therapy for sleep apnea
• Iron supplementation (if iron deficiency is present)
• Targeted medications for movement disorders

---

6. Safety Precautions at Home

While working on treatment, make the environment safer:

• Lock doors and windows
• Install door alarms if needed
• Remove sharp or dangerous objects from the bedroom
• Use gates at the top of stairs
• Avoid bunk beds

These steps are practical and protective—not alarmist.

---

7. Scheduled Awakenings (In Some Cases)

For frequent episodes occurring at predictable times, a doctor may recommend gently waking the person about 15–30 minutes before the usual episode time. This can disrupt the cycle.

---

8. Medication (If Severe)

Medication is not usually the first treatment. However, in cases involving:

• Repeated injuries
• Severe disruption
• High-risk behaviors

Doctors may prescribe medications such as benzodiazepines or certain antidepressants to stabilize sleep stages.

This decision should always be guided by a physician.

---

Can Sleepwalking Be Cured?

In many adults, sleepwalking improves significantly once triggers are managed.

For some, it may not disappear entirely—but episodes can often be reduced to rare, mild events.

The key is identifying and treating underlying causes rather than ignoring the problem.

---

The Bottom Line

Sleepwalking in adults is not automatically dangerous—but it should not be ignored.

Most cases are manageable. However, adult-onset sleepwalking can sometimes signal:

• Sleep deprivation
• Stress overload
• Medication side effects
• Sleep apnea
• Rare neurological conditions

If sleepwalking leads to injury, risky behavior, or begins suddenly, it's important to speak to a doctor. A proper evaluation ensures that serious conditions are ruled out and that you receive appropriate treatment.

If you're unsure about your symptoms, you may consider completing a free, online "symptom check for Sleepwalking" to better understand what might be going on before your appointment.

Above all, if there is any concern about behaviors that could be life-threatening—such as leaving the house, driving, or possible seizure activity—seek medical care promptly.

Sleepwalking can feel unsettling, but with the right evaluation and simple changes, most adults can regain safe, stable sleep.
