Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around and engage in unusual activities while asleep. Sleepwalking is more common in children, with an estimated 5% of children experiencing it annually, and most people grow out of it by adulthood. However, for those who continue sleepwalking into adulthood, it can pose risks of injury and accidents, such as falling down stairs or mishandling sharp objects. Sleepwalking usually occurs within the first few hours of falling asleep and can last from a few seconds to half an hour. While the exact causes are unknown, it is believed to be influenced by genetics, sleep deprivation, and repeated night-time awakenings. Although sleepwalking typically doesn't require treatment, it can impact an individual's quality of life and may warrant medical attention if it frequently disrupts sleep or increases the risk of accidents.

What You'll Learn

Sleepwalking is a sleep disorder
Sleepwalking is more common in children, with 5% of children experiencing an episode in a given year, compared to 1-1.5% of adults. Most people grow out of sleepwalking by the time they reach adulthood, although some continue to experience it less frequently as they age. Sleepwalking is often genetic and tends to run in families. It can also be triggered by stress, strong emotions, sleep deprivation, drug or alcohol use, and intense evening physical activity.
During sleepwalking episodes, individuals may perform a range of actions, from simple behaviours like sitting up in bed or walking to more complex activities such as eating, driving, or even violent behaviour. Sleepwalkers are often unaware of their surroundings and may be at risk of injury due to their lack of coordination and limited problem-solving skills. They typically do not remember the events that occurred during sleepwalking upon waking up.
Sleepwalking usually occurs during the first two to three hours of sleep, in the slow-wave stage of deep sleep. While it usually does not require treatment, it can impact the quality of life and lead to daytime drowsiness. In cases where sleepwalking poses a risk of accidents or severely disrupts sleep, individuals may be referred to a sleep clinic for further evaluation and treatment.
Although sleepwalking is a common disorder, it can have serious consequences, including the risk of injury and legal implications in rare cases of violent behaviour. Understanding sleepwalking and taking preventive measures can help reduce the risks associated with this disorder.

Sleepwalking usually occurs in children
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around and engage in unusual activities while asleep. Sleepwalking usually occurs within the first two or three hours of falling asleep and can last anywhere from a few seconds to 30 minutes. It is widespread in children, with some adults experiencing it too. About 5% to 15% of children sleepwalk, most often between the ages of 4 and 8, and they usually grow out of it by the time they reach puberty.
Sleepwalking is often hereditary, and while it usually isn't a sign of emotional or psychological issues, it can sometimes be linked to underlying conditions such as sleep apnea or night terrors. In most cases, sleepwalking does not require treatment, but it is important to ensure the safety of the sleepwalker, especially children, as they may be at risk of injuries from falling or encountering dangerous objects. Establishing a consistent sleep schedule, a relaxing bedtime routine, and a comfortable sleep environment can help prevent sleepwalking episodes.
Children who sleepwalk may sit up in bed, get out of bed and walk around, or engage in routine activities such as getting dressed. They may also exhibit repeated motions, such as rubbing their eyes or adjusting their pyjamas. Their eyes may be open, but their vision and awareness of their surroundings are limited. Sleepwalking behaviours can include more complex activities such as eating, which may involve consuming inedible items or high-carbohydrate foods.
To ensure the safety of sleepwalking children, parents can take precautions such as gently guiding them back to bed, locking windows and doors, installing alarms, and removing clutter, sharp objects, and potential hazards from their surroundings. While sleepwalking itself is not harmful, it can pose risks if left unaddressed. In rare cases, sleepwalking children may engage in hazardous behaviours such as walking down stairs or opening windows. Establishing good sleep habits and relaxation techniques can help prevent sleepwalking episodes and create a safer environment for children.

Sleepwalking can be dangerous
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around and perform activities while still asleep. While sleepwalking episodes are usually harmless and require no treatment, they can sometimes pose serious risks to the sleepwalker and those around them. Sleepwalking can be dangerous for several reasons:
Risk of Injury
Sleepwalkers are at risk of sustaining injuries due to a lack of coordination and limited awareness of their surroundings. They may engage in complex behaviours, such as walking downstairs, jumping out of windows, or even sleep driving, which can lead to accidents and serious physical harm. In a study, 58% of sleepwalkers presented with a history of violent sleep-related behaviours, with 17% experiencing episodes resulting in injuries requiring medical care. Reported injuries included bruises, nose bleeds, fractures, and even serious head trauma.
Disruption of Sleep and Daytime Fatigue
Sleepwalking episodes can disrupt sleep of the affected individual and those around them. Sleepwalkers may find themselves waking up feeling confused and disoriented. Additionally, sleepwalking is associated with increased daytime sleepiness, fatigue, and insomnia, impacting overall quality of life.
Violent Behaviour
Although rare, there have been instances of sleepwalkers exhibiting violent behaviour during their episodes. This can pose a danger to others in close proximity and may require medical intervention to manage.
Dangerous Activities
In some cases, sleepwalkers may engage in dangerous activities such as cooking or eating inedible items while asleep. These activities can lead to accidents, injuries, or health complications if left unattended.
It is important to note that sleepwalking episodes can be influenced by factors such as stress, sleep deprivation, drug or alcohol intake, and intense evening physical activity. Taking steps to address these triggers can help reduce the frequency and intensity of sleepwalking episodes and mitigate potential dangers.

Sleepwalking can be treated
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around or engage in activities while still asleep. It is quite common among children, with about 5% to 15% of children experiencing it, and often runs in families. Most people grow out of it by the time they reach adulthood, with only about 1% to 1.5% of adults sleepwalking. While sleepwalking usually does not require treatment, there are cases when it can be treated and steps that can be taken to reduce the risk of accidents and repeat episodes.
If sleepwalking is linked to another condition or the use of certain medications, treating the underlying condition or changing the medication may help. In some cases, a doctor may prescribe medication to control sleepwalking if the person is at high risk of injury or if it is causing significant disruptions. However, it is important to note that there are no FDA-approved medications specifically for treating sleepwalking. Some medications that may be prescribed include Gabapentin, Benzodiazepines, and antidepressants. These medications are typically short-term solutions, as they can often be discontinued after a few weeks without a recurrence of sleepwalking.
Additionally, relaxation techniques, mental imagery, and anticipatory awakenings are preferred for the long-term treatment of sleepwalking. Anticipatory awakenings involve waking the person up about 15 to 20 minutes before their usual sleepwalking episode and keeping them awake through it. Creating a safe sleeping environment is also crucial for sleepwalkers. This includes removing any harmful objects, locking doors and windows, covering windows with drapes, and placing an alarm on the bedroom door.
Sleepwalking can also be managed by establishing good sleep hygiene, which includes maintaining a consistent sleep schedule and routine. Other measures to reduce the risk of sleepwalking include getting adequate sleep, limiting stress, meditating or practicing relaxation exercises, and avoiding stimulation before bedtime. While these steps do not guarantee the prevention of sleepwalking, they can help minimize the risk and ensure safety.

Sleepwalking can be triggered by stress
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around or engage in activities while still asleep. It is more common in children, with some adults experiencing it too. Sleepwalking usually occurs within the first few hours of falling asleep and can include unusual activities such as eating, sexual behaviour, or leaving the house. While sleepwalking is often not serious and does not require treatment, it can increase the risk of injury and accidents.
Sleepwalking can be triggered by various factors, and one of them is stress. High stress levels and anxiety are known to trigger sleepwalking episodes. Relaxation techniques and stress management approaches can help reduce the chances of sleepwalking. Cognitive-behavioral therapy (CBT) is a form of psychotherapy that can aid in managing anxiety and stress, thereby reducing the likelihood of sleepwalking. Additionally, scheduled waking, which involves waking up 15 to 30 minutes before the predicted sleepwalking episode, can also help prevent sleepwalking from occurring.
Stress management techniques may include deep breathing exercises, meditation, yoga, or other activities that promote relaxation. These practices can help lower stress levels and improve sleep quality, reducing the frequency of sleepwalking episodes. It is important to note that everyone's experience with stress and sleepwalking is unique, so finding the right combination of stress management techniques may require experimentation and professional guidance.
Addressing underlying mental health conditions that may contribute to stress can also be beneficial in reducing sleepwalking episodes. Conditions such as obsessive-compulsive disorder, major depressive disorder, or schizophrenia have been linked to an increased likelihood of sleepwalking. By seeking professional help and treating these conditions effectively, individuals may find relief from sleepwalking as well. Working with a therapist or mental health provider can help identify stress triggers and develop personalized strategies to manage stress and reduce sleepwalking episodes.
Overall, while stress is not the only factor contributing to sleepwalking, it is a significant one. By incorporating stress management techniques, relaxation practices, and seeking professional help when needed, individuals can effectively reduce the impact of stress on their sleepwalking episodes and improve their overall well-being.
