Sleepwalking, also known as somnambulism, is a phenomenon that occurs during a part of the sleep cycle called slow wave sleep, which is a deep sleep phase. Triggers for sleepwalking can vary greatly from person to person but commonly include lack of sleep, stress, fever, sleep schedule disruptions, certain medications, and substances like alcohol. Genetic factors also play a significant role, as sleepwalking can run in families.
Understanding Sleepwalking
Sleepwalking is classified as a parasomnia — an abnormal behavior that occurs during sleep. It is more common in children than adults and usually occurs during the first third of the night when slow wave sleep is most profound. Individuals who sleepwalk may perform simple to complex tasks, ranging from walking around to cooking or even driving, without any recollection of the episode afterward.
Stages of Sleep and Sleepwalking
During sleep, we cycle through several stages, including rapid eye movement (REM) sleep and non-REM sleep. Sleepwalking typically occurs during the deepest part of non-REM sleep. This part of the cycle is crucial for restorative processes, and disruptions in it can lead to episodes of sleepwalking.
Common Triggers of Sleepwalking
Genetic Predisposition
Studies indicate that sleepwalking may have a hereditary component. If an immediate family member has a history of sleepwalking, chances are higher that other family members may also experience it. This genetic tendency is one reason why sleepwalking is more prevalent in some families.
Sleep Deprivation
Lack of sleep can increase the likelihood of sleepwalking. When the body is deprived of sleep, the pressure to enter deep sleep is stronger, and this intensification of deep sleep may trigger sleepwalking in individuals who are predisposed to it.
Stress and Anxiety
Mental stress and anxiety can significantly affect the quality of sleep and may contribute to episodes of sleepwalking. When an individual is under stress, the chances of disturbances during the sleep cycle increase, potentially triggering an episode.
Fever and Illness
Fever can disrupt the normal sleep pattern, especially in children, and may lead to sleepwalking. Certain illnesses, particularly those that affect the central nervous system, have also been linked to an increased risk of somnambulism.
Medications and Substances
certain medications, including sedatives, antihistamines, stimulants, and some types of antidepressants, can contribute to sleepwalking occurrences. Substance misuse, particularly the consumption of alcohol, can also be a trigger for sleepwalking episodes by altering the normal course of the sleep cycle.
Sleep Schedule Disruptions
Iregulations in one’s sleep schedule, such as jet lag or changes in work shifts, may disrupt the body’s internal clock, leading to an increased possibility of sleepwalking.
Other Sleep Disorders
Conditions like obstructive sleep apnea, restless legs syndrome, and certain forms of insomnia can also be associated with an increased risk of sleepwalking because they can disturb the structure of sleep.
The Sleepwalking Episode
During a sleepwalking episode, a person is in a state of partial arousal. They may be able to perform routine activities but are not fully conscious. Their eyes are typically open with a glassy, staring appearance as they navigate around. There’s generally no recognition of others, and they often have a limited ability to communicate. Most sleepwalkers do not remember the episode, as it occurs during a state of deep, non-REM sleep.
Duration and Frequency of Sleepwalking
Sleepwalking episodes are typically brief, lasting from a few seconds to half an hour. They may occur occasionally or multiple times a night for some. The frequency and pattern of sleepwalking episodes are highly individual.
Managing and Preventing Sleepwalking
While there’s no cure for sleepwalking, there are strategies that one can employ to manage and potentially reduce the occurrences of sleepwalking episodes.
Improving Sleep Hygiene
Maintaining a regular sleep schedule, creating a comfortable sleep environment, and avoiding stimulants before bedtime can improve sleep quality and might reduce the risk of sleepwalking. Consistent bedtime routines are beneficial, especially for children.
Managing Stress
Because stress can be a trigger, it can be helpful to explore stress-reduction techniques such as meditation, yoga, deep breathing, or counseling.

If medications are contributing to sleepwalking, adjustment of dosages or changes in medication under the guidance of a healthcare provider may be necessary. Also, treating underlying sleep disorders or other medical conditions might alleviate the issue.
Safety Precautions
Since sleepwalking can sometimes result in injuries, taking safety precautions is crucial. This includes removing potential obstacles from the bedroom, securing doors and windows, and placing alarms or bells on doors.
Professional Help
Consulting a sleep specialist may be advised for frequent or dangerous sleepwalking episodes. They can help diagnose and treat any underlying conditions and provide tailored advice for managing the problem.
Finishing Thoughts
Sleepwalking is a complex sleep phenomenon that can be triggered by numerous factors. These triggers range from genetic predispositions and stress to disrupted sleep patterns and certain medications. Understanding these triggers is the first step in managing sleepwalking and ensuring the safety and wellbeing of those affected. By maintaining good sleep hygiene, managing stress, addressing potential medical issues, and taking appropriate precautions, individuals can significantly reduce the incidence of sleepwalking and improve their overall quality of sleep.
