Sleepwalking, or somnambulism, is a sleep disorder that involves walking or performing other activities while still asleep. Sleepwalking episodes usually last less than 10 minutes, but can be longer, and can include hazardous activities such as cooking or driving. Sleepwalking is more common in children and can be triggered by factors such as genetics, sleep deprivation, and stress. While sleepwalking is rarely a cause for serious concern, it can be dangerous, and those who sleepwalk may require medical attention if they are at risk of injuring themselves or others.

Sleepwalking causes
Sleepwalking, or somnambulism, is a behaviour disorder that occurs during deep sleep, resulting in walking or performing other complex behaviours while still asleep. While sleepwalking is more common in children, it can persist into adulthood. The exact cause of sleepwalking is unknown, but several factors have been linked to the condition.
Genetics and Family History
Sleepwalking is believed to have a strong genetic component, with a higher prevalence among individuals whose family members have a history of sleepwalking or night terrors. Studies have shown that certain people are genetically predisposed to sleepwalking and other NREM parasomnias.
Sleep Deprivation
Sleep deprivation or disruption can increase the likelihood of sleepwalking. This includes conditions such as insomnia, which can cause excessive daytime sleepiness, and sleep disorders like obstructive sleep apnea (OSA) and restless leg syndrome (RLS). OSA is characterised by breathing interruptions during sleep, resulting in frequent sleep interruptions that may trigger sleepwalking. RLS, on the other hand, creates an urge to move the limbs, especially the legs, upon lying down, leading to nighttime arousals that can initiate sleepwalking episodes.
Stress
Stress, whether physical or emotional, can impact sleep quality and increase the propensity for sleepwalking. Stress-induced sleep fragmentation or disruption can create a state of exhaustion, making individuals more susceptible to sleepwalking episodes.
Fever
Fever, particularly in children, has been associated with an increased likelihood of sleepwalking. It is believed that the higher number of illness-driven arousals during sleep may contribute to sleepwalking episodes.
Medications and Health Conditions
Certain medications and health conditions can also trigger sleepwalking. For example, the medication montelukast, used for asthma, has been linked to sleepwalking in some children. Additionally, gastric disorders such as GERD (gastroesophageal reflux disease) can interfere with sleep, causing long-term exhaustion and increasing vulnerability to sleepwalking. In rare cases, Parkinson's disease, a nerve condition affecting movement and sleep, has been associated with sleepwalking due to its impact on sleep paralysis.

Sleepwalking treatments
Sleepwalking, or somnambulism, is a sleep disorder that usually does not indicate anything serious and may disappear with time, especially in children. However, it can still be disruptive and frightening, and it is important to take safety measures to prevent harm to the sleepwalker or others.
If you or someone you live with sleepwalks, it is recommended to keep a safe sleeping environment. This includes removing any harmful or sharp objects, covering glass windows with heavy drapes, and locking doors and windows. Sleep in a ground-floor bedroom, if possible, and consider placing an alarm or bell on the bedroom door to alert you if the sleepwalker gets out of bed.
Additionally, there are several steps that the sleepwalker can take to lessen the impact of sleepwalking:
- Get adequate sleep
- Limit stress
- Meditate or do relaxation exercises
- Avoid stimulation before bedtime
If the sleepwalker is at risk of injury or family disruption, or if other treatment options have not worked, medication may be prescribed. However, there are currently no FDA-approved medications specifically for sleepwalking. Drugs such as gabapentin, benzodiazepines, and antidepressants may be prescribed off-label to control sleepwalking. It is important to note that medication should only be taken under medical supervision and may be discontinued after several successful weeks of treatment without a recurrence of sleepwalking.
For long-term management of sleepwalking, relaxation techniques, mental imagery, and anticipatory awakenings (waking the sleepwalker 15-20 minutes before a usual sleepwalking episode and keeping them awake through that time) are preferred. These techniques should be undertaken with the help of an experienced behavioural therapist or hypnotist.

Sleepwalking dangers
Sleepwalking, or somnambulism, is a sleep disorder that involves performing activities while in a state of low consciousness. While sleepwalking is generally considered harmless, there are several dangers and health risks associated with the condition.
Sleepwalking can result in injuries, with sleepwalkers often incurring minor injuries such as cuts and bruises. In rare cases, sleepwalkers have suffered fractures and even died as a result of falls during sleepwalking episodes. Sleepwalkers may also face embarrassment if they are found naked in public or perform other embarrassing or inappropriate actions while asleep.
Sleepwalking can also be dangerous if the sleepwalker engages in complex activities that require a higher level of consciousness, such as driving a car, cooking, or handling sharp objects. Sleepwalkers may also experience violent episodes, which can pose a risk to themselves and others around them. Additionally, sleepwalkers may wander outside, increasing the risk of accidents or getting lost.
Furthermore, sleepwalking can impact the quality of life of the affected individual, leading to daytime sleepiness, fatigue, insomnia, and depressive and anxiety symptoms. Sleepwalking can also be a symptom of underlying medical conditions, such as Parkinson's disease, or a side effect of certain medications.
To mitigate the dangers of sleepwalking, it is important to ensure the safety of the sleepwalker and their environment. This includes locking doors and windows, removing hazards, and ensuring a quiet and comfortable sleeping space. If sleepwalking occurs frequently or poses a risk of injury, it is recommended to seek medical advice.

Sleepwalking diagnosis
Sleepwalking, or somnambulism, is a sleep disorder characterised by walking or performing other activities while in a deep sleep. It is much more common in children, with an estimated lifetime prevalence of 6.9% in children compared to 1.5% in adults. Sleepwalking is usually benign and self-limited, and often decreases with the onset of puberty. However, it can be dangerous to the sleepwalker and others in the home, and in some cases, it may persist into adulthood or be associated with other sleep disorders, neurotic traits, and psychiatric disorders. Therefore, it is important to consider sleepwalking diagnosis and treatment.
The first step in diagnosing sleepwalking is to carefully note the patient's case history, including the frequency of sleepwalking episodes, any potential triggers or stressors, and the presence of any other sleep disorders or medical conditions. Physical and neurological examinations are typically normal in sleepwalking children, but they can help rule out other conditions. In some cases, polysomnography (PSG) or electroencephalography (EEG) may be used to assess brain activity during sleep and confirm the diagnosis.
Reassurance is an important aspect of sleepwalking management, as it is often a benign condition. General safety precautions, such as removing sharp or dangerous objects from the bedroom, locking windows and external doors, and blocking access to staircases, can help reduce the risk of injuries during sleepwalking episodes. Establishing a positive bedtime routine and improving sleep hygiene can also help reduce the frequency of sleepwalking episodes. Relaxation techniques, mental imagery, and anticipatory awakenings are recommended for long-term management.
In more severe cases, treatment options may include pharmacological interventions such as low-dose benzodiazepines, gamma-aminobutyric acid (GABA) enhancing agents, or other medications. Behavioural management techniques, such as scheduled awakenings and positive bedtime routines, can also be effective in reducing the frequency of sleepwalking episodes. However, it is important to note that there is no medication specifically approved to treat sleepwalking, and the benefits and risks of any treatment should be carefully considered.

Sleepwalking prevention
Sleepwalking is a sleep disorder that occurs during deep sleep, usually during the first half of the night. Sleepwalkers may walk, talk, sit up, or carry out complex activities while remaining in a deep sleep. While sleepwalking is not usually a cause for concern, it can be dangerous if the sleepwalker interacts with sharp objects or hazardous situations. If you see someone sleepwalking, the best thing to do is to ensure they are safe and gently guide them back to bed. Here are some tips for preventing sleepwalking:
Establish a bedtime routine
Creating a bedtime routine can help regulate sleep patterns and reduce the likelihood of sleepwalking. This includes going to bed and waking up at the same time each day, having a ""power-down hour" before bed to unwind, and finding relaxing activities to do before bed, such as reading or deep breathing.
Create a safe environment
It is important to ensure that the sleepwalker's environment is free of hazards that could cause injury. Remove any breakable or potentially harmful objects, secure loose wires or items that could cause tripping, and keep windows and doors locked. If the sleepwalker is a child, ensure they cannot access the kitchen or any dangerous areas of the home.
Address underlying causes
Sleepwalking can be triggered by various factors, such as sleep deprivation, medications, stress, or other sleep disorders. Try to improve sleep hygiene by limiting caffeine intake and ensuring the sleepwalker goes to the toilet before bed. If other sleep disorders, such as obstructive sleep apnoea or restless legs syndrome, are suspected, seek medical advice.
Wake the sleepwalker gently
If necessary, you can try to wake a sleepwalker gently. Do not shout, startle, or physically restrain them unless they are in danger, as they may lash out. Instead, guide them back to bed calmly and reassuringly. If you must wake them, use loud noises rather than physical contact.
Seek medical advice if needed
Occasional sleepwalking episodes usually do not require medical attention. However, if sleepwalking occurs frequently, there are concerns about the safety of the sleepwalker or others, or if it persists or starts in adulthood, consider consulting a healthcare professional. A GP can refer you to a specialist sleep centre for further evaluation and potential treatment options, such as medication or therapy.

Frequently asked questions
Shift work is an employment practice designed to keep a service or production line operational 24 hours a day. It typically involves dividing the day into shifts, or set periods of time during which different groups of workers perform their duties. Shift work can include evening, night, and early morning shifts, as well as fixed or rotating schedules.
Shift work offers several benefits, including:
- Increased productivity and revenue for businesses
- Greater flexibility and convenience for employees, allowing for better work-life balance
- Less traffic and congestion during commutes
- Better wages, as companies often offer higher pay for non-traditional shifts
Shift work also has several disadvantages, including:
- Sleep problems and disorders, such as insomnia and excessive sleepiness, due to disruptions in circadian rhythms
- Scheduling issues and interference with social or family life
- Higher risk of accidents, both at work and while driving, due to drowsiness and tiredness
- Potential health risks, including cardiovascular disease, cognitive impairment, diabetes, and obesity
Shift work is common in various industries, including healthcare, law enforcement, transportation, manufacturing, and service industries. It is often necessary in healthcare and law enforcement due to the need for 24-hour coverage.
Shift workers can try to maintain a consistent sleep schedule, even on days off, to regulate their body clocks. They should also avoid frequently rotating shifts, limit caffeine intake, and prioritize sleep to mitigate the negative impacts of shift work on their sleep cycles.
