Updated February 28, 2020 Most people don’t know they talk in their sleep. It’s not until they get an elbow or a snicker from their bedmate that they get clued in on this nighttime behavior. Sleep talking usually doesn’t make sense. The thoughts do not emerge from a person’s rational mind and are not a reflection of what a person thinks or believes. Sleep talking might be a little embarrassing, but it usually isn’t anything to worry about. But why do people talk in their sleep? Let’s review some common causes of sleep talking and what can be done to address it. What Is Sleep Talking? Sleep talking is called somniloquy. Sleep disturbances are more common in children than in adults. Only about 4% of adults live with sleep disturbances. Talking in your sleep doesn’t put you in danger of telling your deepest darkest secrets. Most sleep talking takes the form of short phrases, moans, or mumbling. These jumbled statements are usually snippets of memories from the past or even thoughts about the future or people we know. A sleep talker might jumble three or four concepts into one short mumble. It usually doesn’t make sense to the person who hears it — or even to the person who says it. In some rare cases, sleep talkers may have entire conversations with themselves. Sleep vocalizations are sometimes accompanied by quick movements of the body. A sleep talker might quickly sit upright, then lie back down as if nothing happened. Symptoms of Sleep Talking It’s unlikely that a person who sleep talks has noticed any symptoms. Only a person in the room with the sleep talker is able to hear what is happening while the person sleeps. When Does Sleep Talking Happen? It’s possible to dream at any point while you are sleeping, but the majority of people dream most vividly during rapid eye movement or REM sleep. During this stage, the brain purposely paralyzes the body. Sleep scientists believe this happens so we can’t act out our dreams. It’s during this time that a small part of the brain might be left lingering awake. This is when disturbances like sleepwalking and talking take place. Is Sleep Talking a Mental Health Disorder? No connection between sleep talking and mental health disorders has been identified. However, some psychiatric disorders like schizophrenia cause episodes of nonsensical talking, gibberish, or mumbling. It’s unlikely a person will have their first mental health episode in the middle of the night. Yet, a mental health episode can happen at any time, and it could look similar to sleep talking. If you have a personal or family history of mental illness, keep track of sleep episodes. Is Sleep Talking a Sleep Disorder? Somniloquy can be normal and benign, but sometimes it can be a sign of a type of sleep disorder called arousal disorder. These disorders include sleepwalking, night terrors, and nocturnal sleep-related eating disorder. Sleep talking isn’t considered an arousal disorder because the talking episodes are brief. If the episodes are long and involve moving the body or opening the eyes, they could be caused by a sleep disorder. In these cases, it is time to have a sleep specialist evaluate you for a more serious disorder. Who’s at Risk for Sleep Talking? People under the age of 25 are most at risk for sleep talking. Usually, sleep talking is benign. Sometimes, it may be a side effect of a medical condition. Sleep Talking and Rapid Eye Movement Sleep Behavior Disorder Another sleep disorder that may be confused for sleep talking is called rapid eye movement sleep behavior disorder (RBD). When a person acts out their dreams, this is an indication of RBD. This disorder is often linked to Parkinson’s disease and other neurodegenerative diseases. Signs of RBD include flailing limbs and talking or shouting while sleeping. A person with RBD will have vivid recall of the dream even after waking from it. RBD is more common in men over the age of 50 than in any other group. Because RBD is a sign of a serious health condition, if you move while you sleep talk, you should be evaluated by a sleep specialist. Sleep Talking and Catathrenia If a sleep talker groans loudly when exhaling while asleep, it can be a sign of a sleep-related breathing disorder called catathrenia. Catathrenia can be treated with continuous positive airway pressure (CPAP) used at night. Is Sleep Talking a Neurological Disorder? It’s not impossible for a person to experience a seizure while sleeping. A seizure during sleep is called a nocturnal seizure. It’s important to note if you have any risk factors, signs, or symptoms of a seizure disorder. If so, your sleep talking should be investigated by a healthcare professional. Why Do People Talk in Their Sleep? There are many cases where sleep talking is not a sign of a sleep disorder: Day-time drowsiness, usually caused by poor sleep the previous night, is linked with sleep talking. Sleep deprivation in general is also linked to sleep talking. Depression and anxiety are both linked with poor sleep, which can lead to sleep talking. Illness with a high fever can even cause a person to talk in their sleep. Sleep talking is believed to be genetic and passed down through families. Does Sleep Talking Require Treatment? In most cases, sleep talking is not accompanied by a sleep disorder. When this is the case, it will usually wane as a child becomes an adult and disappear over time. Sleep hygiene often solves sleep problems attributed to sleep talking. If you are overtired from sleep deprivation, the following night’s sleep might not be as restful as it could be, which can lead to sleep talking. Identifying triggers can be a useful tool for promoting sleep hygiene. Keeping a sleep diary including incidents of sleep talking can help you do this. Creating a safe space for sleep includes leaving emotional stress outside the bedroom. For most people, this means making the room as comfortable as possible. This might look like a bed with soft sheets and pillows. Setting a sleep schedule can help you wake at the same time and sleep at the same time. This routine gets your body clock on a schedule and is beneficial for sleep problems. Preventing Sleep Talking Sleep specialists have yet to find a way to cease sleep talking completely. Sleep science is growing every day, and we may know more about the roots of sleep talking in the not too distant future. For now, improving sleep quality and avoiding unnecessary stress is the best tool for a better, more restful night. Frequent sleep talking is not very common in people over 25 years old. If you are over 25 and sleep talk persistently, or if your sleep talking continues or worsens over time, a sleep study may give you answers. Consult a sleep specialist for a potential sleep study to rule out any other causes of the sleep talking. Bring a partner with you who can adequately describe your sleep talking episodes. In the meantime, focusing on sleep hygiene and reducing stress can help you get a better night’s rest and reduce the likelihood of sleep talking.
