Sleep sex, or sexsomnia, is a rare sleep disorder where a person engages in sexual acts while in non-rapid eye movement (NREM) sleep. The person experiencing sexsomnia may have their eyes open and appear awake, but they are actually unconscious and unaware of their actions. They may also exhibit an abnormally heightened level of sexual aggression and decreased inhibitions. Sexsomnia is often discovered by a partner, roommate, or family member, and it can be treated with medication and better sleep hygiene.

Sleep sex, or sexsomnia, is a sleep disorder
Sexsomnia is a parasomnia, or an abnormal activity that occurs while an individual is asleep. It is a relatively new condition, with the first official case reported in 1986, and according to a 2015 study, only 94 cases of sleep sex have been documented worldwide. Sexsomnia is considered rare, with one study finding that 8% of people at a Canadian sleep disorder clinic showed symptoms of the condition. Men were found to be three times more likely than women to have sexsomnia.
The symptoms of sexsomnia vary depending on the person, but the underlying feature is that a sleeping person exhibits sexual behaviours that they are unaware of and unable to control. These behaviours can include masturbation, thrusting, intercourse, fondling, and spontaneous orgasm. People with sexsomnia often have no recollection of the sexual behaviours they exhibit while asleep, and may only find out about their condition from a partner, roommate, or family member. The person may appear awake during an episode of sexsomnia, with an open-eyed, vacant look, but they are actually experiencing an amnesic episode.
The exact cause of sexsomnia is not known, but it is often associated with a wide range of underlying conditions and risk factors. These include other parasomnias such as sleepwalking and REM sleep behaviour disorder, as well as medical conditions such as sleep apnea, teeth grinding, and the use of certain medications. Environmental and lifestyle factors can also contribute to the onset of sexsomnia, with commonly reported triggers including stress, anxiety, depression, alcohol and substance use, and sleep deprivation.

It is a type of parasomnia, or abnormal activity during sleep
Sleep sex, or sexsomnia, is a type of parasomnia, an abnormal activity, behaviour, or experience that occurs during sleep. Parasomnias are undesirable physical events or experiences with autonomic nervous system activity that occur during any stage of sleep or when transitioning to or from wakefulness. Sexsomnia is characterised by an individual engaging in sexual acts while in non-rapid eye movement (NREM) sleep.
Sexual behaviours that result from sexsomnia are distinct from normal nocturnal sexual behaviours, which do not occur during NREM sleep. Normal nocturnal sexual behaviours are accompanied by extensive research and documentation and include nocturnal emissions, nocturnal erections, and sleep orgasms. Sexsomnia, on the other hand, can include masturbation, thrusting, intercourse, or spontaneous orgasm. It is important to note that sexsomnia is not a conscious act and the individual is often unaware of their actions.
The symptoms of sexsomnia vary from person to person, but the underlying feature is that the sleeping person exhibits sexual behaviours that they are unaware of and unable to control. Sexsomnia can be difficult to diagnose, and a variety of factors are considered to determine the presence of the condition. It is often first noticed by a partner, roommate, or family member who observes the unusual behaviour. The person with sexsomnia may appear awake with their eyes open, but they are actually experiencing an amnesic episode and will have no recollection of their actions.
Sexsomnia is considered rare, and its exact prevalence is not well understood. One study found that 8% of people at a Canadian sleep disorder clinic showed symptoms of sexsomnia, with men being three times more likely to exhibit symptoms than women. However, due to factors such as embarrassment or shame, the condition may be underreported. Sexsomnia often occurs alongside other parasomnias, such as sleepwalking and sleep talking, and can be triggered by various factors, including sleep deprivation, stress, anxiety, fatigue, certain medications, alcohol consumption, and substance use.

Symptoms vary but the underlying feature is a sleeping person exhibiting sexual behaviours they are unaware of
Sleep sex, or sexsomnia, is a distinct form of parasomnia, which is an abnormal activity that occurs while an individual is asleep. The symptoms of sexsomnia vary depending on the person, but the underlying feature is a sleeping person exhibiting sexual behaviours that they are unaware of and unable to control.
Sexual behaviours that result from sexsomnia are not to be mistaken with normal nocturnal sexual behaviours, which do not occur during NREM sleep. Sexual behaviours that are viewed as normal during sleep and are accompanied by extensive research and documentation include nocturnal emissions, nocturnal erections, and sleep orgasms.
People with sexsomnia may engage in masturbation, thrusting, intercourse, or spontaneous orgasm. They may also seek sexual intimacy with others without knowing it. Sexsomnia can be identified by a person's unresponsiveness or minimal responsiveness to conversation, unusual sexual responses or aggression, and an inability or difficulty to be woken during the act. The person experiencing sexsomnia may have their eyes open and appear awake, but they are actually experiencing an amnesic episode and will not remember anything.
Sexsomnia is often diagnosed in males beginning in adolescence, and men are three times more likely than women to exhibit symptoms of sexsomnia. It can be caused by or associated with other parasomnias, such as sleepwalking and REM sleep behaviour disorder, as well as medical conditions, lifestyle habits, jobs, and medications that interfere with sleeping patterns. Triggers for sexsomnia include stress, anxiety, fatigue, irregular sleep patterns, alcohol consumption, substance use, and sleep deprivation.
Treatment for sexsomnia involves identifying the condition and addressing the underlying causes. This may include maintaining a healthy and regular sleep-wake schedule, stopping or reducing the use of certain medications or substances, and making lifestyle adjustments.

It is often diagnosed in males and can be treated with medication and better sleep hygiene
Sleep sex, or sexsomnia, is a sleep disorder characterised by an individual engaging in sexual acts while in non-rapid eye movement (NREM) sleep. It is a distinct form of parasomnia, or an abnormal activity that occurs while an individual is asleep. Sexsomnia is often diagnosed in males, typically beginning in adolescence, and can be challenging to identify as those affected often appear awake and conscious, with their eyes open, despite being completely unaware of their actions.
The underlying feature of sexsomnia is that the affected individual exhibits sexual behaviours that they are unaware of and unable to control. These behaviours can include masturbation, sexual movements, sexual aggression, or initiating sex with another person. It is important to note that sexual behaviours resulting from sexsomnia should not be mistaken with normal nocturnal sexual behaviours, such as nocturnal emissions, nocturnal erections, and sleep orgasms, which do not occur during NREM sleep.
As there is no FDA-approved medication specifically designed for treating sexsomnia, health professionals typically address the disorder through various approaches. Treatment for sexsomnia often involves medication, improving sleep hygiene, and reducing stress or triggers. Benzodiazepines, such as clonazepam, have been prescribed to treat sexsomnia by acting on the GABA-A receptors in the central nervous system. Additionally, treating underlying conditions that cause sleep disruption, such as sleep apnea, may help reduce or resolve cases of sexsomnia.
Improving sleep hygiene is crucial for managing sexsomnia. This includes following a consistent sleep schedule, winding down at the end of the day, and maintaining a regular bedtime routine. Creating a safe environment is also essential, and precautionary measures may include the individual sleeping in a separate bedroom and installing locks and alarms on doors. Lifestyle changes, such as reducing alcohol consumption and recreational drug use, can also help prevent episodes of sexsomnia.

Triggers include sleep deprivation, stress, anxiety, fatigue, alcohol, and substance use
Sexsomnia, or sleep sex, is a sleep disorder that causes people to engage in sexual behaviours while asleep, such as masturbation, intercourse, and sexual motions. The person experiencing sexsomnia is usually unaware of their actions and has no recollection of them after they wake up. It is a type of parasomnia, which is an abnormal activity, behaviour, or experience that occurs during sleep.
Sexsomnia can be triggered by a variety of factors, including sleep deprivation, stress, anxiety, fatigue, alcohol consumption, and substance use. Sleep deprivation, for example, has been shown to negatively impact brain function and behaviour, leading to potential disruptions in sleep cycles and an increased risk of sexsomnia. Similarly, stress, anxiety, and fatigue can also disrupt sleep patterns and trigger episodes of sexsomnia.
Alcohol consumption and substance use are also commonly associated with sexsomnia. Alcohol can affect sleep quality and increase the likelihood of sleep disturbances, making it a potential trigger for sexsomnia. Substance use, including illegal drugs and even some over-the-counter sleep aids, can have similar effects, disrupting sleep and triggering sexsomnia episodes.
These triggers can vary from person to person, and not all cases of sexsomnia can be linked to a specific trigger. However, addressing these factors and improving sleep hygiene can help reduce the risk of sexsomnia and improve overall sleep quality. This may include maintaining a consistent sleep schedule, winding down before bed, and creating a relaxing sleep environment.
