Sleepwalking, also known as somnambulism, is a sleep disorder that involves walking or performing other activities while still mostly asleep. It occurs during the slow-wave stage of sleep, when people are in a state of low consciousness. Sleepwalking can range from simple behaviours such as talking or sitting up in bed, to more complex actions like driving a car or cooking, which can be dangerous. Sleepwalkers are often not aware of their actions and may feel confused or scared if woken up during an episode. While sleepwalking is more common in children, it can persist into adulthood and be influenced by factors such as genetics, sleep deprivation, stress, or certain medications.

What You'll Learn
Sleepwalking is a sleep disorder
Sleepwalking, or somnambulism, is a sleep disorder characterised by a combination of sleep and wakefulness. Sleepwalking usually occurs within the first few hours of falling asleep, during the slow-wave stage of non-rapid eye movement (NREM) sleep. During this stage, the sleepwalker is in a state of low consciousness, with limited awareness of their physical surroundings. While sleepwalking, individuals may engage in a range of activities, from simple behaviours like sitting up in bed or walking to more complex actions such as driving or cooking. These actions can pose a risk of injury to the sleepwalker and others.
Sleepwalking is most common in children, with an estimated 1% of childhood sleepwalkers continuing the behaviour into adulthood. While it is generally not a cause for concern, it can be a hazard, especially if the sleepwalker engages in dangerous activities. Sleepwalking itself is not harmful, but it can increase the risk of accidents, such as falling down stairs or encountering dangers outside the home. Therefore, it is essential to take precautions to ensure the safety of sleepwalkers, such as locking windows and doors and removing sharp objects from their environment.
The sleepwalker's eyes are typically open during an episode, but their vision and perception are altered. They may have a glassy-eyed stare or blank expression, and their pupils are dilated. While they can navigate their surroundings to some extent, their movements are often clumsy and uncoordinated. Sleepwalkers usually have little to no memory of their nocturnal activities, as their altered state of consciousness makes recalling memories difficult.
While sleepwalking is generally not a cause for medical intervention, it is recommended to establish good sleep hygiene practices to reduce the frequency of episodes. This includes maintaining a consistent sleep schedule, avoiding caffeine before bed, and ensuring the sleepwalker goes to the bathroom before sleeping to prevent a full bladder from triggering an episode. In rare cases where sleepwalking persists into adulthood or causes significant problems, medical treatment may be considered, such as scheduled awakening or medication.
Sleepwalking is a fascinating sleep disorder that has intrigued and puzzled people for centuries. While it usually poses little harm, it can have dangerous consequences in certain situations. By understanding the nature of sleepwalking and taking appropriate precautions, we can help ensure the safety of those who wander in their sleep.

It occurs during deep sleep
Sleepwalking, or somnambulism, is a sleep disorder characterised by a combination of sleep and wakefulness. Sleepwalking occurs during the slow-wave sleep (N3) stage of non-rapid eye movement sleep (NREM) cycles, also known as deep sleep. During this stage, the sleepwalker experiences a state of low consciousness, with limited awareness of their physical surroundings. While sleepwalking, individuals may engage in activities that are typically performed while fully awake, such as talking, sitting up in bed, walking, consuming food, or even more complex tasks. However, they remain in a state of altered consciousness, with limited memory of their actions.
Sleepwalking usually occurs within the first two to three hours of falling asleep, during the first third of the night when slow-wave sleep is most prominent. It is more common in children, with an estimated 1% of childhood sleepwalkers continuing the behaviour into adulthood. While sleepwalking itself is not harmful, it can pose hazards due to the reduced sensory perception and coordination of the sleepwalker. Sleepwalkers may engage in potentially dangerous activities such as falling down stairs, wandering outside, or even sleep driving, requiring precautions to ensure their safety.
The sleepwalker's eyes are typically open, but their vision and perception are altered. They may have a glassy-eyed stare or blank expression, and their pupils are dilated. While they can navigate their surroundings to some extent through simple stumbling and habit, their understanding of their environment may be distorted. They may believe they are in a different room or place altogether, leading to confusion and potential risks.
The causes of sleepwalking are not fully understood, and episodes can occur unpredictably. However, certain factors may trigger sleepwalking episodes. For example, sleepwalking may run in families, indicating a potential genetic influence. Additionally, maintaining good sleep hygiene, including a consistent sleep schedule and avoiding caffeine close to bedtime, can help reduce the likelihood of sleepwalking episodes.
While sleepwalking usually does not require medical treatment, it is essential to take precautions to ensure the safety of the sleepwalker and those around them. This may include guiding them gently back to bed, locking windows and doors, and removing potential hazards from their environment. In cases where sleepwalking persists into adulthood or causes significant problems, consulting a doctor is recommended.

Sleepwalking can cause injuries
Sleepwalking, or somnambulism, is a sleep disorder that occurs during slow-wave sleep, typically in the first third of the night. Sleepwalkers may engage in a range of activities, from benign behaviours such as talking or walking to the bathroom, to more hazardous activities like cooking, driving, or even violent gestures. While sleepwalking may seem benign, it can pose serious risks of injuries to the sleepwalker.
Sleepwalkers have an increased risk of injuries due to their lack of coordination and limited awareness of their surroundings. They may suffer injuries from falling down stairs, jumping out of windows, or other accidents that can occur when navigating their environment while asleep. In some cases, sleepwalkers have reported sustaining severe fractures or breaking bones during their sleepwalking episodes.
The risk of injury is further exacerbated by the fact that sleepwalkers often do not feel pain during their episodes. A study found that among sleepwalkers who suffered injuries, 79% did not wake up immediately due to pain. Instead, they remained asleep, only feeling the pain later or even after waking up in the morning. This lack of pain perception can result in sleepwalkers continuing their activities despite sustaining injuries, potentially leading to more severe or compounded injuries.
The dissociative state of arousal during sleepwalking episodes may be responsible for the altered pain perception. Sleepwalkers may not recall their actions upon awakening, exhibiting complete amnesia of the episode. However, they may notice signs of their nocturnal activities, such as overturned furniture or personal injuries like scratches and wounds.
To prevent injuries, it is important for individuals who sleepwalk or live with someone who sleepwalks to take precautions. This may include setting a consistent sleep schedule and routine, creating a safe environment by removing hazards, and seeking medical advice to reduce the frequency of sleepwalking episodes. By taking these steps, the potential dangers associated with sleepwalking can be mitigated.

Sleep deprivation is a trigger
Sleepwalking, or somnambulism, is a sleep disorder where a person walks or performs other activities while still asleep. It usually occurs within the first few hours of falling asleep, during the slow-wave stage of non-rapid eye movement (NREM) sleep. While sleepwalking is generally not serious, it can lead to injuries and accidents. Sleepwalkers often have limited awareness of their surroundings and may engage in hazardous activities such as cooking or driving.
Sleepwalking is more common in children, but some adults also experience it. It can run in families, with a higher likelihood of sleepwalking if one or both parents have a history of sleepwalking. Sleepwalking typically decreases with age, and only about 1% of people who sleepwalked as children continue to do so as adults.
Sleep deprivation is a significant trigger for sleepwalking. A lack of sleep increases the risk of sleepwalking episodes, and maintaining good sleep hygiene is crucial to reducing this risk. This includes establishing a consistent sleep schedule, avoiding caffeine and alcohol close to bedtime, and managing stress. Sleepwalking can also be influenced by other factors such as genetics, medications, stress, and underlying sleep disorders.
Sleepwalking usually occurs during a state of partial awakening, where an individual becomes active but does not fully wake up. Sleepwalkers may have a glassy-eyed stare, dilated pupils, and limited coordination. They often have little to no memory of their actions during sleepwalking episodes. While sleepwalking can include simple, repeated behaviors, there are rare reports of people performing complex tasks while asleep.
To prevent injuries and promote safety during sleepwalking episodes, it is recommended to lock doors and windows and remove breakable objects from the sleepwalker's environment. Establishing a consistent sleep schedule and routine can also help reduce the risk of repeat sleepwalking episodes. While sleepwalking itself may not require active treatment, seeking medical advice is essential to address any underlying sleep disorders or conditions that may be contributing factors.

Sleepwalkers may feel confused when woken
Sleepwalking, also known as somnambulism or noctambulism, is a sleep disorder characterised by a combination of sleep and wakefulness. Sleepwalkers may engage in various activities, from benign behaviours like talking or sitting up in bed to more hazardous activities such as cooking or driving. While sleepwalking is typically associated with walking around during sleep, it can encompass a range of actions performed while in a state of low consciousness.
When it comes to waking a sleepwalker, it is generally recommended to do so gently. Sleepwalkers may experience confusion and disorientation if they are abruptly awakened. They may not immediately comprehend their surroundings or the situation, leading to feelings of bewilderment and uncertainty. This confusion arises from the sleepwalker's altered state of consciousness during the sleepwalking episode. Their memory of the events that occurred while sleepwalking may also be limited or absent, contributing to their confusion upon waking.
It is important to approach a sleepwalker with calmness and gentleness. Attempting to wake them gradually can help reduce the potential for confusion and distress. However, it is worth noting that even with gentle awakening, some sleepwalkers may still exhibit signs of confusion or disorientation momentarily. They may struggle to fully comprehend their actions or the environment they find themselves in. This disorientation is a result of the altered state of consciousness associated with sleepwalking.
Additionally, it is worth mentioning that sleepwalking usually occurs during the first two to three hours of sleep, within the slow-wave stage of non-rapid eye movement (NREM) sleep. This stage is characterised by low consciousness, which may contribute to the confusion experienced by sleepwalkers upon waking. Their limited awareness during the episode can result in a lack of memory regarding their actions, further contributing to their confusion.
While sleepwalking itself is not typically harmful, the potential for injury exists due to the sleepwalker's reduced awareness and coordination. Therefore, it is essential to prioritise safety by guiding the sleepwalker back to bed gently and ensuring their environment is secure to prevent accidental harm. Taking precautions, such as establishing a safe sleep environment and maintaining a consistent sleep schedule, can help reduce the frequency of sleepwalking episodes and minimise the risk of injury.
