Sleepwalking, or somnambulism, is a sleep disorder that involves walking or performing other complex behaviours while asleep. It is often portrayed in the arts, such as Shakespeare's Macbeth and Bellini's opera La Sonnambula, perhaps due to its exploration of boundaries and psychological elements. Sleepwalking is believed to occur when two areas of the brain—the limbic region and the cortex—remain awake, while the frontal cortex and hippocampus are asleep. While sleepwalking is usually harmless and doesn't require medical attention, it can sometimes pose dangers to the sleepwalker or others, in which case treatment options are available.

What You'll Learn
Sleepwalking is a sleep disorder
The exact cause of sleepwalking is unknown, but it appears to have a genetic component, as it tends to run in families. Various factors, such as sleep deprivation, medications, stress, and other sleep disorders, can trigger or contribute to sleepwalking episodes. Obstructive sleep apnea and restless leg syndrome, for example, are known to cause frequent awakenings during the night, which can trigger sleepwalking.
During a sleepwalking episode, individuals may exhibit a range of behaviours, from simple actions like getting out of bed and walking around to more complex activities like playing an instrument or even driving a car. Sleepwalkers typically have a blank expression on their faces and may appear awake but act clumsy. They usually have no recollection of their actions upon waking, often learning about their sleepwalking behaviour from family members or housemates.
While sleepwalking itself is not harmful, it can pose safety risks and lead to injuries. Sleepwalkers may trip and fall, collide with objects, or engage in potentially dangerous activities without being fully conscious of their actions. It is important to ensure the safety of sleepwalkers by removing hazards, locking doors and windows, and seeking medical advice if sleepwalking persists or poses a risk of self-harm or harm to others.
Although there is no specific treatment for sleepwalking, certain measures can be taken to manage the condition. Establishing a regular and relaxing bedtime routine, limiting caffeine intake, and ensuring adequate sleep hygiene are recommended. In some cases, cognitive behavioural therapy (CBT) or hypnotherapy may be helpful. For frequent or severe sleepwalking, medications such as benzodiazepines or antidepressants may be prescribed to aid sleep and reduce the frequency of episodes.

It occurs when two areas of the brain remain awake
Sleepwalking is a sleep disorder that involves walking or performing other complex behaviours while not fully awake. It usually occurs during a period of deep sleep, typically in the first few hours after falling asleep. Sleepwalking episodes can last anywhere from a few seconds to half an hour, and the person may either wake up confused or return to bed on their own. While the exact cause of sleepwalking is unknown, it appears to have a genetic component and is more common in children, with an estimated 1 in 5 children sleepwalking at least once.
Now, onto the core question: how does sleepwalking work, and specifically, how is it linked to certain areas of the brain remaining awake? Sleepwalking occurs when two areas of the brain remain awake while the rest is asleep. The two areas are the hippocampus and the parietal lobe. The hippocampus is responsible for memory and spatial navigation, which is why sleepwalkers are able to walk around and even perform complex tasks. The parietal lobe, which is usually responsible for integrating sensory information, remains active and controls the sleepwalker's movements.
During sleepwalking episodes, the sleepwalker's eyes may appear glassy, and they may have a blank expression on their face. They might look awake but act clumsy, and their actions can range from simply getting up and walking around to more complex activities such as driving a car or playing an instrument. While sleepwalking itself is not harmful, it can become hazardous if the sleepwalker trips and falls, collides with objects, or mishandles sharp tools. It is important to ensure the safety of sleepwalkers by removing potential hazards and locking doors and windows.
If sleepwalking occurs frequently, causes concern for the safety of the sleepwalker or others, or persists into adulthood, it is recommended to seek medical advice. Treatments such as scheduled awakening, medications, cognitive behavioural therapy (CBT) or hypnotherapy may be suggested. Establishing a regular sleep routine, limiting drinks and caffeine before bedtime, and ensuring a comfortable sleeping environment can also help reduce the occurrence of sleepwalking episodes.

Sleepwalking can be dangerous
Sleepwalking, or somnambulism, is a sleep disorder that can affect both children and adults. Sleepwalkers may walk or perform other complex behaviours while not fully awake. While sleepwalking is often portrayed in a humorous or harmless light, it can pose serious risks and be incredibly dangerous for both the sleepwalker and those around them.
Sleepwalking can result in injuries to the sleepwalker or others, with reported injuries including bruises, nosebleeds, fractures, and even serious head trauma. Sleepwalkers may trip and fall, collide with objects, or mishandle sharp objects. They may also engage in violent behaviour or attempt complex activities such as driving a car, which can have life-threatening consequences.
Additionally, sleepwalking can impact the quality of life for both the sleepwalker and those around them. Sleepwalkers may experience daytime sleepiness, fatigue, insomnia, and altered moods, including depressive and anxiety symptoms. The condition can also cause embarrassment or shame due to behaviours exhibited during sleepwalking episodes, such as sexually explicit behaviour or urinating in inappropriate places.
The dangers of sleepwalking are particularly prominent in adults, as episodes can be more frequent and severe, with a higher risk of violent behaviour and injuries. If sleepwalking occurs frequently, there is a concern for potential self-harm or harm to others, or if it persists into adulthood, it is recommended to seek medical advice. Treatment options may include medication, cognitive behavioural therapy, or hypnotherapy.
To minimise the risks associated with sleepwalking, it is important to ensure the safety of the sleepwalker and their environment. This may include gently guiding the sleepwalker away from potential hazards, keeping the home free of breakable or harmful objects, and ensuring windows and doors are locked.

It can be treated with medicine or therapy
Sleepwalking is a sleep disorder that usually occurs during a period of deep sleep, within the first few hours of falling asleep. While sleepwalking is not harmful in itself, it can be hazardous and lead to injury or embarrassment. If sleepwalking persists into adulthood or poses a risk of harm to oneself or others, it can be treated with medicine or therapy.
Medicine is not usually the first port of call for treating sleepwalking. However, in cases where sleepwalking occurs frequently and poses a risk of serious injury, medications such as benzodiazepines or antidepressants may be prescribed to aid sleep and reduce the frequency of sleepwalking episodes.
Therapies such as cognitive behavioural therapy (CBT) or hypnotherapy may also be recommended to help treat sleepwalking. These therapies can provide individuals with the tools and strategies to manage their sleepwalking and reduce its impact on their lives.
In addition to medical and therapeutic interventions, establishing a regular and relaxing bedtime routine is crucial for individuals who sleepwalk. This includes limiting caffeine intake, ensuring a quiet and comfortable sleep environment, and addressing any underlying sleep disorders or triggers that may be contributing to the sleepwalking behaviour.
If you or someone you know is experiencing frequent sleepwalking that is causing concern, it is important to seek advice from a healthcare professional. They can provide personalised guidance and support to ensure the safety and well-being of the individual.

It is more common in children
Sleepwalking is a sleep disorder that involves walking or performing other complex behaviours while not fully awake. Sleepwalking usually occurs during a period of deep sleep, typically in the first few hours after falling asleep. While sleepwalking can affect both children and adults, it is more common during childhood. In fact, it is thought that 1 in 5 children will sleepwalk at least once, with sleepwalking being more common in boys than in girls. Most children tend to outgrow sleepwalking by the time they reach puberty, although it can sometimes persist into adulthood.
There are several factors that may trigger sleepwalking episodes in children. Genetics is one factor, with sleepwalking tending to run in families. If other members of a child's close family have a history of sleepwalking or night terrors, the child is more likely to sleepwalk. Sleep deprivation is another potential trigger, with children who do not get enough sleep being more prone to sleepwalking. Additionally, certain medications and stress can also contribute to sleepwalking episodes.
The exact cause of sleepwalking is not fully understood, and it is important to recognise that sleepwalking itself is not harmful. However, sleepwalking can create hazardous situations for children. During a sleepwalking episode, a child may not be fully aware of their surroundings or actions, which can lead to accidental injuries. For example, a sleepwalking child might walk down stairs, open windows, or even attempt to drive a car. Therefore, it is crucial for parents to take precautions to ensure their sleepwalking child's safety. This includes keeping the home safe by removing potential hazards, locking windows and doors, and ensuring their child's bedroom is comfortable and cosy.
If a child frequently sleepwalks, parents can try gently waking them about 15 to 30 minutes before their usual sleepwalking time. This method, known as "scheduled awakening," can help alter the child's normal sleep cycle and potentially stop the sleepwalking behaviour. Establishing a regular sleep schedule and bedtime routine can also be beneficial. This includes making sure the child gets enough sleep, limiting drinks and caffeine before bedtime, and ensuring they go to the toilet before sleeping. If parents have concerns about their child's sleepwalking, it is recommended to consult a doctor or GP, especially if the child is at risk of injuring themselves or others.

Frequently asked questions
Sleepwalking, or somnambulism, is a sleep disorder where a person walks or carries out activities while not fully awake. Sleepwalking occurs during a period of deep sleep, usually in the first few hours after falling asleep.
Experts are unsure of the exact causes of sleepwalking. Genetics may play a role, as children of sleepwalkers have a higher chance of sleepwalking themselves. Other sleep disorders, such as obstructive sleep apnoea and restless leg syndrome, can also trigger sleepwalking episodes.
Sleepwalking usually doesn't require direct treatment. If it is causing issues, it is best to consult a doctor, who can refer you to a specialist sleep centre if needed. Loved ones who witness sleepwalking can provide details or videos that can aid in a sleepwalking diagnosis.
Sleepwalkers typically have little to no memory of the incident and may feel confused upon waking up. Sleepwalking does not indicate dementia or other physical disorders, and it is distinct from alcohol or drug-induced blackouts.
