Sleep groaning, also known as catathrenia, is a rare, typically harmless sleep disorder that causes people to moan, groan, hum, or make cracking sounds while asleep. The groaning sound is usually quite loud and occurs during exhalation. While the exact cause of catathrenia is unknown, it is believed to be related to individual factors such as dysfunctional neurons in the brain, small upper airways, small jaws, limited airflow upon exhale, and low-diversity salivary microbiota. Diagnosis of catathrenia is usually made via a sleep study called a polysomnogram, and treatment options include CPAP therapy, oral appliances, and surgery.

Sleep groaning is likely catathrenia, a rare, harmless sleep disorder
Sleep groaning is likely catathrenia, a rare disorder that causes people to moan, groan, hum, or make cracking sounds while asleep. The groaning sounds are usually quite loud and very different from other sleep sounds, like snoring or talking. They are also distinct from the sounds of sleep apnea, which occur during inhalation rather than exhalation.
Catathrenia is typically harmless and not considered dangerous or life-threatening. It is not believed to be caused by psychological or psychiatric stress, and it is not associated with decreased oxygen levels during sleep. However, it can negatively affect the sleep quality of those with the condition and their bed partners. People with catathrenia may wake up feeling unrefreshed and experience extreme tiredness, insomnia, nocturia, and other parasomnias such as sleep talking, sleepwalking, and teeth grinding.
The exact cause of catathrenia is unknown, but it is classified as a sleep-related breathing disorder. It is often associated with abnormal breathing patterns, such as slow breathing or breath-holding, and there may be links to dysfunctional neurons in the part of the brain that controls breathing, small upper airways, small jaws, or inspiratory flow limitation. Some scientists also believe there may be a genetic component, as some people with catathrenia have a close relative with the condition.
A polysomnogram, or overnight sleep study, can be used to diagnose catathrenia. This test will show changes in breathing patterns and can record the groaning sounds. Treatment options for catathrenia include CPAP therapy, oral appliances, and surgery, although the condition is so rare that optimal treatments are still unknown.

Catathrenia is associated with breathing problems and abnormal brain activity
Catathrenia, or nocturnal groaning, is a rare sleep disorder that causes a person to moan, groan, hum, or make cracking sounds while asleep. The groaning sounds are usually made during exhalation and are often described as very loud and distinct from other sleep sounds like snoring or talking.
The exact cause of catathrenia is unknown, but it is believed to be related to individual factors, including dysfunctional neurons in the brain, small upper airways, small jaws, limited airflow upon exhale, and low-diversity salivary microbiota. Specifically, it is thought that the disorder is related to the neurons in the respiratory center of the brain, or the medulla oblongata. If these neurons are dysfunctional, they can trigger prolonged exhalation, which creates a moaning or groaning sound as the vocal cords vibrate.
Catathrenia is often diagnosed when it is so loud that it disturbs others. Diagnosis typically involves a sleep test called polysomnography, which can indicate abnormal breathing disturbances and limited airflow. A physical examination of the head, neck, jaw, and tonsils may also be conducted to identify possible markers associated with the condition.
Treatment options are available and include CPAP therapy, oral appliances, and surgery. These treatments aim to address the breathing problems and abnormal brain activity associated with catathrenia, helping to reduce symptoms and improve sleep quality for both the affected individual and their sleeping partner.

Groaning can be caused by craniofacial abnormalities, disrupting airflow
Sleep groaning, or catathrenia, is a rare sleep disorder that causes people to groan, moan, hum, or make cracking sounds while asleep. The cause of catathrenia is not well understood, but it is believed to be associated with an underlying sleep-related breathing problem. One theory suggests that the groaning may be caused by craniofacial abnormalities, which disrupt airflow during sleep.
Craniofacial abnormalities refer to structural differences in the face and skull that can affect the airway. In the context of sleep groaning, these abnormalities can obstruct airflow during exhalation, resulting in the characteristic groaning noise. This can include having a small jaw or small upper airways, which can restrict the airflow and cause the groaning sound.
The structure of the face and skull can vary significantly between individuals, and these variations can influence the shape and size of the airway. In some cases, these structural differences can lead to a narrowing of the airway, making it more difficult for air to flow freely during sleep. This restricted airflow can then result in the vocal cord vibrations that produce the groaning sound associated with catathrenia.
While the exact cause of sleep groaning is still unknown, research suggests that it may be related to a combination of factors, including dysfunctional neurons in the brain's respiratory center, small upper airways, and craniofacial abnormalities. These factors can work together to disrupt the normal breathing pattern during sleep, leading to the distinctive groaning sounds of catathrenia.
It is important to note that sleep groaning is typically harmless and is not usually a symptom of any serious underlying health condition. However, it can cause social embarrassment and negatively affect relationships and sleep quality. If sleep groaning is causing disturbances or concerns, it is recommended to consult a healthcare professional for advice and potential treatment options.

Treatments include CPAP therapy, oral appliances, and surgery
Sleep groaning, or catathrenia, is a rare sleep disorder that causes people to moan, groan, hum, or make cracking sounds while asleep. The cause of catathrenia is not well understood, but it is believed to be associated with an underlying sleep-related breathing problem. Groaning typically occurs during exhalation and can last anywhere from 30 seconds to a minute. While catathrenia is usually harmless, it can lead to non-refreshing or frequently interrupted sleep, which has been linked to serious health issues.
If sleep groaning is causing sleep disruption or fatigue, it is recommended that you contact your doctor. Diagnosis of catathrenia is typically done through a sleep study called a polysomnogram or polysomnography, which can show changes in breathing patterns and record groaning sounds. A physical exam of the head, neck, jaw, nose, mouth, and throat may also be conducted to identify possible obstructions to breathing.
Treatments for catathrenia include CPAP therapy, oral appliances, and surgery. CPAP, or continuous positive airway pressure, therapy involves the use of a machine that delivers pressurized air through a mask worn during sleep. This therapy ensures the windpipe stays open and prevents the airway from collapsing. While CPAP is considered the best treatment for improving airflow, it can be challenging for some people to use consistently due to factors such as comfort and compliance. Oral appliances are an alternative treatment option for those who cannot use CPAP machines. These devices work by pulling the jaw or tongue forward to open the airway and improve breathing. Oral appliances include mandibular advancement devices and tongue-stabilizing devices, and they can be used in conjunction with CPAP therapy to reduce the amount of pressurized air delivered. While surgery is considered a last resort, it may be an option for those who do not respond to other treatments. Surgical procedures can include jaw surgery to adjust the position of the jaw and nasal surgery to straighten the soft tissue in the nose, improving airflow.

Catathrenia can cause insomnia, nocturia, and other parasomnias
Catathrenia, or nocturnal groaning, is a rare sleep disorder that causes people to groan or moan loudly while sleeping. It occurs during REM sleep, the period of sleep in which memories and dreams are consolidated. While the exact cause of catathrenia is unknown, it is believed to be related to individual factors such as dysfunctional neurons in the brain that control breathing, small upper airways, small jaws, limited airflow upon exhale, and low-diversity salivary microbiota.
People with catathrenia may experience insomnia, which is characterised by difficulty falling or staying asleep, resulting in poor sleep quality. Nocturia, or the frequent urge to urinate at night, was also reported by more than half of the people in a study on catathrenia. Additionally, about 57% of people in the same study reported other parasomnias, which are unusual or undesirable behaviours that occur while falling asleep, during sleep, or upon waking up. These parasomnias included sleep talking, sleepwalking, and teeth grinding.
The treatment options for catathrenia include CPAP therapy, oral appliances, and surgery. These treatments aim to reduce symptoms and help improve sleep quality for both the affected individual and their sleeping partner. While catathrenia itself is typically harmless, the associated symptoms, such as insomnia and nocturia, can cause significant disruptions to one's sleep and daily functioning. Therefore, it is essential to seek medical advice and explore suitable treatment options to manage catathrenia and its related symptoms effectively.
Furthermore, catathrenia often comes to medical attention when the groaning noises disturb others. The loud groaning can be disruptive in shared sleeping environments, such as dorms or when sharing a bed with someone for the first time. A sleep study, called a polysomnogram, can be conducted to diagnose catathrenia and rule out other potential sleep disorders or breathing issues. This test will record the groaning sounds and measure changes in breathing patterns.
In summary, catathrenia, or nocturnal groaning, is a rare sleep disorder that can lead to insomnia, nocturia, and other parasomnias. The disorder is characterised by loud groaning during sleep, typically during exhalation. Treatment options are available to manage the symptoms and improve sleep quality for both the affected individual and their sleeping partner.
