Sleepwalking, or somnambulism, is a partial arousal from deep sleep, usually occurring during the Non-Rapid Eye Movement (NREM) stage of sleep. While sleepwalking is not harmful to health, it can cause problems due to safety concerns. There is a lot of debate about whether one should wake a sleepwalker or not. While it is not dangerous to wake a sleepwalker, it is generally advised against as it can lead to disorientation, confusion, and even agitation. Experts suggest that the best course of action is to gently guide the sleepwalker back to bed without waking them.

What You'll Learn
Sleepwalking is harmless but can be dangerous
Sleepwalking, or somnambulism, is a behaviour disorder that occurs during deep sleep, resulting in walking or performing other complex tasks while not fully awake. It is believed to be caused by the brain's difficulty in properly regulating sleep and wake cycles. While sleepwalking is generally harmless, it can sometimes lead to dangerous situations.
Sleepwalking episodes can range from simple actions, such as sitting up in bed and looking around, to more complex behaviours like getting dressed, eating, or even driving. During these episodes, sleepwalkers may appear confused, agitated, or exhibit blank facial expressions. The episodes typically last a few minutes to half an hour, and the sleepwalker usually has no memory of their actions upon waking.
The occurrence of sleepwalking is more common in children, with an estimated 29% of children aged 2 to 13 experiencing it, and it often goes away as they mature. However, about 4% of adults also experience sleepwalking, and it can persist into adulthood or begin later in life due to underlying causes. Sleepwalking can be triggered or worsened by various factors, including sleep deprivation, family history, stress, and other sleep disorders.
While sleepwalking is usually harmless, it can become dangerous if the sleepwalker is at risk of injuring themselves or others. In such cases, it may be necessary to wake the sleepwalker or guide them back to bed. However, waking a sleepwalker should be done gently, as they may feel disoriented, confused, or scared upon waking. It is recommended to use a quiet, soothing voice and avoid physical contact or shaking, as they may lash out due to feeling threatened.
In summary, sleepwalking is a common occurrence, especially in children, and is usually harmless. However, it can occasionally lead to dangerous situations, and it is important to ensure the safety of the sleepwalker and those around them. If frequent or concerning sleepwalking episodes occur, it may be advisable to consult a doctor or sleep specialist for further evaluation and potential treatment options.

Sleepwalkers are at risk of injury
Sleepwalking, or somnambulism, occurs when a person gets up from bed and walks around while still asleep. It can also involve other complex actions, such as performing routine daily activities or behaviours that are strange or out of place. Sleepwalking is generally harmless and often requires no active treatment, particularly in children, where it is more common. Episodes tend to lessen with age and pose little risk to the sleepwalker or those around them.
However, sleepwalkers are at risk of injuring themselves. Sleepwalking can be triggered by various factors, including genetics, sleep deprivation, certain medications, and stress. These factors can increase the likelihood of sleepwalking episodes, which can result in accidents and injuries. For example, a sleepwalker might climb out of a window or move furniture around, potentially leading to harm. Therefore, it is essential to eliminate safety risks by taking preventative measures such as locking doors and keeping sharp objects out of reach.
If you encounter someone who is sleepwalking, it is generally safe to wake them, contrary to the common misconception that doing so will cause them harm. However, it is important to do so carefully, as they may feel startled or under threat and exhibit a stress response, such as lashing out. Instead of touching or shaking them, it is recommended to make loud, sharp noises from a safe distance. Once they are awake, they may be confused and scared, so providing reassurance and guiding them gently back to bed can be helpful.
If sleepwalking episodes are frequent or intense, seeking medical advice is advisable. A sleep doctor may recommend completing a sleep diary and questionnaire to gather information about the patient's sleep patterns and medical history. This information helps determine any underlying causes or contributing factors, such as sleep apnea or certain medications, and develop an appropriate treatment plan.

Sleepwalking is difficult to remember
Sleepwalking, or somnambulism, is a sleep disorder that causes people to walk or carry out activities while not fully awake. It usually occurs during the first few hours of deep sleep, and the person sleepwalking is in a state of partial wakefulness, with limited awareness of their surroundings. This lack of full consciousness results in sleepwalkers typically having no memory or only a vague recollection of their sleepwalking episode.
The memory of sleepwalking is often patchy or non-existent, and this is due to the nature of the sleep state. During sleepwalking, the person is in a state of non-rapid eye movement (NREM) sleep, where their muscles are not paralysed as they are in REM sleep. This allows them to physically act out their dreams or perform activities such as walking, but the memory of these actions is not stored or easily retrievable.
The brain's limited ability to form and retain memories during NREM sleep contributes to the forgetfulness associated with sleepwalking. While the sleepwalker's eyes may be open, they are not fully conscious or aware of their surroundings. Their brain is still largely in a sleep state, and the formation of new memories is impaired. This results in a lack of recall or only fragmented memories of the event.
Additionally, the stress and confusion that often accompany the sleepwalking episode can further impact memory retention. When woken from sleepwalking, individuals may feel disoriented and confused, which can affect their ability to form clear memories of the event. The stress response triggered by the sudden awakening can also interfere with memory formation and retrieval processes, leading to a lack of recollection.
It is important to note that while sleepwalking itself is generally harmless and does not affect sleep quality, it can pose risks of injury to the sleepwalker or others. Therefore, preventive measures and safe interventions are crucial. If a sleepwalker cannot be gently guided back to bed, they should be awakened safely from a distance without touching or shaking them, as this can trigger a stress response and cause them to lash out. Once awake, sleepwalkers will gradually become oriented and may experience a return of some memory of their sleepwalking episode.

Sleepwalking is often genetic
Sleepwalking, or somnambulism, is a common sleep disorder that affects up to 4% of adults and 29% of children aged 2 to 13. While sleepwalking episodes are generally harmless, sleepwalkers are at risk of injuring themselves or others. It is a myth that waking a sleepwalker will harm them; in fact, if they are in danger or likely to cause harm, it is advisable to wake them. However, it is difficult to wake a sleepwalker, and they may be confused, disoriented, and exhibit a stress response if awakened aggressively. Therefore, it is recommended to guide them gently back to bed without touching or shaking them.
Sleepwalking is often associated with bedwetting and is usually outgrown by adulthood. However, when it persists into adulthood or begins later in life, there may be underlying causes. Research supports a strong genetic basis for sleepwalking, with some studies identifying specific genes and inheritance patterns. Sleepwalking has been shown to run in families, with a recent study finding a high prevalence of sleepwalking in an extended family that supported previous reports of a genetic link.
Genetic studies have identified a haplotype consisting of seven single nucleotide polymorphism markers on chromosome 20q12-q13.12 that is common to all individuals with a history of sleepwalking in a particular family. This chromosome region contains approximately 28 known or predicted genes, and the inheritance pattern of sleepwalking in this family was determined to be autosomal dominant with reduced penetrance. This means that sleepwalking may be transmitted as a genetic trait, even if all family members do not exhibit the disorder.
While the exact genes and inheritance patterns responsible for sleepwalking are still being studied, the identification of these genetic markers is a crucial step in improving the understanding, diagnosis, and treatment of this disorder. Optimizing treatment for sleepwalking is essential due to its potential to cause injury and disrupt sleep quality for both the affected individual and their loved ones. Further research and understanding of the genetics of sleepwalking will enable the development of more effective strategies to manage and prevent this disorder.

Sleepwalking can be treated by a specialist
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around or engage in activities they would normally do while awake. While sleepwalking is generally harmless, sleepwalkers are at risk of injuring themselves or others. Sleepwalking is more common in children, with 29% of children aged 2 to 13 experiencing it, and it often goes away on its own before adulthood. However, when it persists into adulthood or starts later in life, underlying medical or genetic causes may be to blame.
If sleepwalking is causing harm to oneself or others, it is recommended to consult a sleep specialist. Sleep specialists can prescribe medication to manipulate a sleepwalker's sleep cycle and prevent abnormal movements. They may also recommend a full sleep study (polysomnography) to confirm sleepwalking and rule out other conditions. While there are no FDA-approved drugs specifically for sleepwalking, medication can be helpful in the short term.
In addition to medication, sleep specialists may recommend non-medication approaches such as relaxation and stress management techniques. These techniques can include mental imagery, anticipatory awakenings, and meditation. Anticipatory awakenings involve waking a person 15-20 minutes before a sleepwalking episode usually occurs and keeping them awake during the time the episodes typically happen. Relaxation and mental imagery techniques are most effective when done with the guidance of an experienced behavioural therapist or hypnotist.
Psychotherapy is another treatment option that can help address anxiety, stress, and other factors contributing to sleepwalking episodes. Sleepwalking can also be influenced by lifestyle factors such as lack of sleep, stress, and a noisy sleeping environment, so making changes in these areas can be beneficial. Overall, while sleepwalking can be challenging to manage, treatment by a specialist can help to reduce the frequency and impact of sleepwalking episodes.

Frequently asked questions
No, sleepwalking itself does not cause any health problems. However, sleepwalkers are at risk of injuring themselves. Waking a sleepwalker will not cause them to have a heart attack or any other serious trauma.
If you can, gently guide them back to bed without waking them. If you must wake them, do it gently and avoid making loud noises or touching or shaking them as they may feel attacked and lash out in self-defence.
They will likely be confused and disoriented, so explain what happened and provide reassurance as you encourage them to return to bed.
There is no consensus on the best approach. Waking a sleepwalker may be unsuccessful and lead to disorientation, but it might be necessary to prevent them from injuring themselves.
