Sleep talking, or somniloquy, is a type of parasomnia — an abnormal behaviour that occurs during sleep. While the exact causes of sleep talking are unknown, it is believed to be triggered by factors such as jet lag, sleep deprivation, sleep apnea, and family history. Sleep talking is more common in children, with half of young children experiencing it compared to 5% of adults. It can occur during any stage of sleep and usually does not require medical attention as it is often harmless. However, it can cause disruption to bed partners or roommates, affecting their sleep quality.
| Characteristics | Values |
|---|---|
| Commonness | Sleep talking is very common, with 50% of young children experiencing it at least once a year. 5-25% of adults talk in their sleep. |
| Heritability | Sleep-talking parents are more likely to have children who sleep-talk. |
| Age | Sleep talking is most common during adolescence. |
| Occurrence | Sleep talking can occur many times during a sleep cycle and during both NREM and REM sleep stages. |
| Risk | Sleep talking is generally harmless but can indicate a more serious sleep disorder or health condition in some cases. |
| Memory | Sleep talkers usually don't remember anything that's said during sleep. |
| Treatment | Sleep talking usually doesn't require treatment. However, managing stress, maintaining a regular sleep routine, and avoiding stimulants and electronics before bed may help reduce its occurrence. |
| Related Disorders | Sleep talking is associated with REM sleep behavior disorder (RBD), sleep apnea, sleep deprivation, anxiety, stress, alcohol or substance misuse, and depression. |

What You'll Learn
Sleep talking is a parasomnia
Sleep talking, or somniloquy, is a parasomnia. Parasomnias are abnormal behaviours during sleep. Sleep talking is a sleep disorder defined as talking during sleep without being aware of it. Sleep talking can come and go and can occur during any stage of sleep. It can range from simple mumbling sounds to loud shouts or long, frequently inarticulate, speeches. It can occur many times during a sleep cycle and during both NREM and REM sleep stages. However, it most commonly occurs during NREM sleep or temporary arousals therefrom.
Sleep talking is considered distinct from other vocalizations that can occur during sleep, such as catathrenia, a breathing disorder that causes audible groaning. Unlike sleep talking, which can come and go, catathrenia often occurs nightly. Although it doesn't affect general health, it can affect sleep quality. Sleep talking can also be a side effect or symptom of other parasomnias. For example, people with REM sleep behaviour disorder (RBD) tend to unknowingly act out their dreams. Sleep talking is usually harmless, but in some cases, it might indicate a more serious sleep disorder or health condition.
The exact cause of sleep talking is unclear, but it may be triggered by disrupted sleep patterns, stress, mental health conditions, sleep deprivation, sleep apnea, anxiety, alcohol or substance misuse, and daytime drowsiness. Sleep talking is very common and is reported in 50% of young children at least once a year. A large percentage of people progressively sleep-talk less often after the age of 25. Sleep talking may also be hereditary, as children of sleep-talking parents are more likely to sleep-talk.
Sleep talking usually does not require treatment, but it can be reduced by improving sleep hygiene, such as avoiding stimulants and electronics before bed and managing stress. In some cases, behavioural treatments, such as using an automated auditory signal to produce an aversive sound when the person starts talking in their sleep, have been successful in eliminating sleep talking.

It occurs in both REM and non-REM sleep
Sleep talking, or somniloquy, is a sleep disorder that involves speaking aloud while asleep. It can range from simple mumbling to loud shouts or long, frequently inarticulate, speeches. Sleep talking usually occurs without the person's knowledge and they rarely remember anything said. While sleep talking is often harmless, it can sometimes indicate a more serious sleep disorder or health condition.
Sleep talking can occur during any stage of the sleep cycle, including both REM and non-REM sleep. REM sleep is the deep sleep phase when most dreams occur, and it is characterised by rapid eye movement. Non-REM sleep, on the other hand, is when the body relaxes and prepares for deeper sleep. During this stage, the body temperature drops, heart rate slows, and brain waves become slower and larger.
Sleep talking is more common during non-REM sleep, particularly during delta-wave NREM sleep or temporary arousals from this stage. When sleep talking occurs during REM sleep, it is considered a "motor breakthrough", where words spoken in a dream are spoken out loud. This is often associated with REM sleep behaviour disorder (RBD), where individuals act out their dreams.
The exact cause of sleep talking is not fully understood, but it is believed to be triggered by various factors. These factors include stress, mental health conditions, sleep deprivation, sleep apnea, anxiety, alcohol consumption, and substance misuse. Sleep talking can also be hereditary, with a higher likelihood of occurrence if one's parents are sleep talkers.
While sleep talking is generally harmless, it can be disruptive to bed partners and cause embarrassment if one's sleep banter is overheard. In rare cases, sleep talking in adults may be linked to psychiatric disorders or nocturnal seizures. Therefore, it is recommended to focus on improving sleep quality and consult a healthcare provider if concerns persist.

It's more common in children than adults
Sleep talking, or somniloquy, is a sleep disorder that occurs when a person speaks while asleep without being aware of it. It is a type of parasomnia, an abnormal behaviour during sleep. Sleep talking can occur during any stage of sleep and is usually harmless. However, in some cases, it may indicate a more serious sleep disorder or health condition, such as REM sleep behaviour disorder (RBD) or sleep apnea.
Sleep talking is more prevalent in children than adults, with half of young children experiencing it compared to only 5% of adults. Dr. Pavlova, a neurologist, offers several possible explanations for this discrepancy:
- Brain Maturity: The brain of a child is not yet fully mature, resulting in a less smooth transition between wakefulness and sleep compared to an adult's brain. As children grow older, their sleep talking tends to decrease.
- Longer Sleep Needs: Children require more sleep than adults, and their growth and development depend on uninterrupted sleep.
Additionally, other factors can contribute to sleep talking in both children and adults. These include stress, mental health conditions, sleep deprivation, jet lag, and certain medications. Maintaining a consistent sleep schedule, limiting screen time before bed, and creating a relaxing sleep environment can help reduce the occurrence of sleep talking.
While sleep talking is generally benign, it can be disruptive to bed partners or family members. Partners can use earplugs or white noise machines to minimise disruptions. If sleep talking persists and is a concern, it is advisable to consult a doctor or sleep specialist for further evaluation and potential treatment options.

Sleep deprivation can trigger it
Sleep talking, or somniloquy, is a sleep disorder that involves talking during sleep without being aware of it. It can range from simple mumbling to loud shouts or long, frequently inarticulate, speeches. Sleep talking usually occurs by itself and is often harmless. However, in some cases, it could indicate a more serious sleep disorder or health condition.
Sleep deprivation can trigger sleep talking. Sleep talking can occur during any stage of sleep, and a lack of sleep can create a biological tension between wanting to stay awake during the day and falling asleep at night. Sleep talking can also be a side effect of other parasomnias, such as REM sleep behaviour disorder, where people unknowingly act out their dreams.
Sleep talking can be disruptive, especially to bed partners. It can wake others and cause them concern, especially when misinterpreted as conscious speech. Sleep talking may also be a symptom of other sleep disorders such as sleep apnea, where people wake up gasping for air due to a lack of oxygen.
If improving your sleep doesn't reduce sleep talking, it may be a good idea to get an overnight sleep study. This can provide valuable information about brain and body activity during sleep and help rule out other sleep disorders. Treatment for sleep talking is rarely required as it generally doesn't disturb sleep or cause other issues. However, in some cases, behavioural treatments or focusing on sleep hygiene can help limit the frequency of episodes.

It can run in families
Sleep talking, or somniloquy, is a sleep disorder that can occur during any stage of the sleep cycle, including both rapid eye movement (REM) and non-rapid eye movement (non-REM) sleep. While sleep talking is generally harmless, it can sometimes be a sign of a more serious sleep disorder or health condition.
Sleep talking is believed to be hereditary and often runs in families. Research from 1966 suggests that sleep-talking parents are more likely to have children who sleep-talk. Sleep-talking can still occur when neither parent has a history of it, but this is much less common. Additionally, a large proportion of people who begin to sleep-talk later in life have no prior history of sleep-talking during childhood or adolescence.
The exact cause of sleep talking is unclear, but it may be triggered by various factors, including stress, mental health conditions, sleep deprivation, daytime drowsiness, alcohol consumption, fever, and certain medications. Sleep talking is also associated with other sleep disorders such as confusional arousals, sleep apnea, and REM sleep behaviour disorder.
If you are concerned about your sleep talking or your bed partner's sleep talking, it may be helpful to consult a healthcare professional. They may recommend an overnight sleep study to monitor your brain waves, heart rate, breathing, and body movements during sleep. Treatment for sleep talking is typically not required, but in some cases, behavioural treatments or sleep hygiene improvements may be suggested.
