Sleepwalking, or somnambulism, is a sleep disturbance where a person performs actions in their sleep as if they were awake. Sleepwalking episodes can include various activities, from sitting up in bed to performing complex tasks such as driving a car. Sleepwalking usually occurs within the first few hours of falling asleep, during the deepest part of the sleep cycle, and can last anywhere from a few seconds to half an hour. While sleepwalking is more common in children, affecting 29% of children aged 2 to 13, it can persist into adulthood, with approximately 4% of adults experiencing it. If sleepwalking is causing safety concerns, disrupting sleep, or affecting daily functioning, it is recommended to consult a doctor for advice and potential treatment options.

Sleepwalking causes
Sleepwalking, or somnambulism, is a behaviour disorder that occurs during deep sleep, resulting in walking or performing other complex behaviours while mostly asleep. Sleepwalking usually happens during the first part of the night and can last anywhere from a few seconds to half an hour. It is more common in children, with 5% of children and 1.5% of adults experiencing an episode in the last year. Most children outgrow sleepwalking by their teenage years.
There are several factors that can increase the likelihood of sleepwalking episodes:
- Genetics and family history: Studies have shown that certain people are genetically predisposed to sleepwalking. Sleepwalking is more likely to occur if other family members also sleepwalk.
- Sleep deprivation: Lack of sleep or repeated nighttime awakenings can contribute to sleepwalking episodes.
- Stress: Physical or emotional stress can affect sleep quality, leading to more disrupted sleep and an increased propensity for sleepwalking.
- Fever: In children, fever has been associated with an increased likelihood of sleepwalking, possibly due to illness-driven arousals during sleep.
- Obstructive sleep apnea (OSA): OSA is a sleep disorder characterised by breathing interruptions due to airway blockage. These breathing pauses can cause sleep interruptions that may trigger sleepwalking.
- Restless Leg Syndrome (RLS): RLS is a sleep disorder that creates a compelling urge to move the limbs, particularly the legs, when trying to sleep. The nighttime arousals caused by RLS can lead to sleepwalking episodes.
While sleepwalking typically does not require treatment, it is important to address any underlying conditions or medications that may be contributing factors. If sleepwalking is frequent, severe, or puts an individual at risk of accidents, a healthcare provider may refer them to a sleep clinic for further evaluation and treatment.

Sleepwalking dangers
Sleepwalking, or somnambulism, is a sleeping disturbance that occurs during the deepest part of non-rapid eye movement (NREM) sleep. During sleepwalking episodes, the brain is partially awake and can perform complex behaviours, but it is still mostly asleep and has no conscious awareness of its actions. While most episodes of sleepwalking are harmless, sleepwalking can be dangerous and can result in serious health consequences.
Sleepwalking can cause injury to the sleepwalker or others, as they may trip and fall, collide with objects, or mishandle sharp objects. In a study of 100 patients with a history of repeated sleepwalking, 57.9% had been injured or had injured someone else during an episode. Sleepwalking can also involve attempting to drive a car or performing other tasks without being fully conscious, which can be life-threatening. Sleepwalking can also have consequences for bed partners, roommates, or housemates, as it can cause disruptions to their sleep and negatively affect them.
Additionally, sleepwalking has been associated with increased daytime sleepiness, fatigue, insomnia, depressive and anxiety symptoms, and a decreased quality of life. Sleepwalking may be triggered or made worse by stressful events, strong emotions, sleep deprivation, drug or alcohol intake, and intense evening physical activity. It is also believed that sleepwalking may be influenced by genetics and family history, with certain people being genetically predisposed to sleepwalking.
If sleepwalking is frequent and causing distress or dysfunction during the day, it may be considered a disorder. Treatment for sleepwalking is usually not necessary, as most children outgrow it by their teenage years. However, if sleepwalking persists into adulthood or is severe, a doctor may recommend treatment or refer to a sleep clinic to rule out underlying conditions or medications that may be causing it. Keeping a sleep diary can help identify triggers for sleepwalking and determine if any patterns or underlying conditions are contributing to the behaviour.

Sleepwalking symptoms
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around or engage in activities that should only be performed while awake. It is characterised by partial waking, where the person becomes active but does not fully awaken. Sleepwalking usually occurs within the first two to three hours of falling asleep, during the deep sleep stage of the sleep cycle.
The most obvious symptom of sleepwalking is getting out of bed and walking around while still asleep. Sleepwalkers' eyes are typically open, but their vision is different from when they are awake. They may believe they are in a different room or location altogether. Sleepwalkers may also sit up in bed and repeat actions like rubbing their eyes or fidgeting with their pyjamas.
Sleepwalking can involve simple or complex actions, such as routine activities like walking around the house or getting dressed, or more intricate tasks like eating, sexual behaviour, or leaving the house. Episodes can last anywhere from a few seconds to half an hour, and the sleepwalker may either wake up confused or return to bed on their own. Sleepwalkers rarely remember the episode when they wake up.
While sleepwalking itself is not harmful, it can be hazardous as sleepwalkers may not be aware of their surroundings or actions, increasing the risk of accidents and injuries. Sleepwalking children, for example, may walk down stairs or open windows without realising the potential dangers. In rare cases, sleepwalking can lead to violent behaviour, causing harm to the sleepwalker or others.
Sleepwalking is more common in children, with an estimated 5% to 15% of children experiencing it, compared to 1% to 1.5% of adults. It often runs in families, and most people outgrow it by adulthood. However, for those who continue sleepwalking into adulthood, the episodes typically become less frequent over time.

Sleepwalking treatments
Sleepwalking, also known as somnambulism, is a sleep disorder that involves complex behaviors that occur during sleep. It usually happens during the deep stages of sleep and can range from simple, repetitive actions to complex and potentially dangerous activities. If you find yourself sleepwalking, there are several treatments and strategies that can help manage this condition and ensure your safety.
- Improve Sleep Hygiene: Establishing good sleep habits is crucial for treating sleepwalking. Maintain a consistent sleep schedule by going to bed and waking up at the same time each day. Create a relaxing bedtime routine to help your body wind down and prepare for sleep. This could include activities such as reading, listening to soothing music, or practicing relaxation techniques like deep breathing or meditation. Ensure your bedroom is cool, dark, and quiet, and minimize distractions like loud noises or bright lights.
- Reduce Stress and Anxiety: Stress and anxiety can trigger and worsen sleepwalking episodes. Incorporate stress management techniques into your daily routine, such as yoga, mindfulness meditation, or journaling. Practice deep breathing exercises before bed to promote relaxation and calm your mind. Identify and address the sources of stress in your life, and consider seeking support from a therapist or counselor if needed.
- Create a Safe Environment: Ensure your sleeping area is free from hazards that could cause injury during a sleepwalking episode. Keep the path between your bed and the bedroom door clear of obstacles. Lock windows and doors, and consider installing alarms on them to prevent accidental exits. If you live in a multi-level home, use gates at the top and bottom of staircases. Sleep on the ground floor if possible, and if you share a room, consider moving temporarily to a private room to avoid disturbing others.
- Medication: In severe or persistent cases of sleepwalking, medication may be prescribed. Medications such as clonazepam or benzodiazepines can help relax the central nervous system and reduce the occurrence of sleepwalking episodes. Always consult a healthcare professional before taking any medication, as they can guide you through the benefits, risks, and potential side effects.
- Cognitive-Behavioral Therapy (CBT): CBT is a type of talk therapy that can help you identify and change negative thought patterns and behaviors that may be contributing to your sleepwalking. A therapist can work with you to develop strategies for improving sleep hygiene, stress management, and relaxation techniques. CBT can also help address any underlying psychological issues that may be triggering sleepwalking episodes.
- Maintain a Sleep Diary: Keep a record of your sleep patterns and any sleepwalking incidents. Note the time you go to bed, the time you wake up, and any sleepwalking episodes, including what happened and how you felt afterward. A sleep diary can help you identify patterns, triggers, and the effectiveness of your treatment strategies. It can also provide valuable information for your healthcare provider in assessing your condition.
Remember, sleepwalking is a treatable condition, and with the right combination of strategies, you can manage it effectively. It is important to be patient and consistent in implementing these treatments, as it may take time to see improvements. If you have concerns or if sleepwalking is significantly impacting your life, consult a sleep specialist or healthcare provider for personalized advice and support.

Sleepwalking in children
Sleepwalking, or somnambulism, is a common occurrence in children, with 5% experiencing an episode in the last year. It is generally harmless and most children outgrow it by their teenage years. Sleepwalking typically occurs within one to two hours of falling asleep and episodes can last from a few seconds to 30 minutes. During an episode, a child may walk around, sit up in bed, or go through repeated motions such as rubbing their eyes. They may also engage in more complex behaviours such as trying to drive a car. While sleepwalking itself is not harmful, it can be hazardous if the child walks down stairs, opens windows, or handles sharp objects.
If your child is a sleepwalker, there are several precautions you can take to ensure their safety. It is recommended to lock windows and doors in their bedroom and throughout your home, especially if your child is old enough to drive. You may also consider installing extra locks or child safety locks out of their reach. Keep keys, sharp objects, and other dangerous items out of reach, and remove any obstacles or clutter from their room and the house to prevent trips and falls. Lowering the temperature in their bedroom to below 75°F (24°C) may also help.
To help prevent sleepwalking, it is important to establish good sleep habits and a relaxing bedtime routine. This includes going to bed at the same time every night, taking a warm bath, or listening to soothing music. Limit liquids, caffeine, and sugar before bedtime, and ensure your child empties their bladder before sleeping. If your child's sleepwalking continues or is causing disruptions, consider keeping a sleep diary to identify any triggers and consult your doctor for further advice or a potential referral to a sleep clinic.
In some cases, sleepwalking can be linked to underlying conditions such as sleep apnea or night terrors. If you suspect your child's sleepwalking is related to another medical issue, consult your doctor for a proper diagnosis and treatment. They may recommend a sleep study or other tests to rule out any potential causes and provide appropriate care.
