Catathrenia, or nocturnal groaning, is a rare sleep disorder characterised by strange noises during exhalation
Catathrenia, or nocturnal groaning, is a rare sleep disorder characterized by unusual vocalizations during exhalation while asleep. These vocalizations can include moaning, sighing, or groaning sounds, and they can occur repeatedly throughout the sleep cycle. This condition is distinct from other sleep disorders such as sleep talking or sleep apnea and requires specialized attention to diagnose and manage. The exact cause of catathrenia is not fully understood, but it is believed to involve a combination of physiological and neurological factors. Those with this condition are often unaware of their vocalizations and may only become aware if a bed partner or family member brings it to their attention.
The characteristic sounds of catathrenia result from a prolonged exhalation phase, during which airflow from the lungs causes the vocal cords to vibrate, producing a sustained and sometimes loud moaning or groaning noise. This abnormal breathing pattern is thought to be associated with changes in brain activity during sleep, particularly in the transition between non-rapid eye movement (NREM) sleep stages. While the exact mechanisms are still a subject of research, it is believed that a disruption in the normal respiratory control during sleep leads to the unique breathing and vocal patterns observed in catathrenia.
Individuals with catathrenia may exhibit a range of symptoms, although the primary indicator is the presence of unusual noises during sleep. These sounds can vary in volume and tone, from soft sighs to louder moans or even cries. In some cases, the vocalizations may be so loud that they disturb the sleep of others in the same household. Additionally, those with catathrenia might experience shortness of breath or a feeling of breathlessness during the groaning episodes. Unlike other parasomnias, catathrenia is not associated with sudden bodily movements or behaviors; instead, the sleeper typically remains still while producing these vocalizations.
The diagnosis of catathrenia typically involves a comprehensive evaluation by a sleep specialist. This may include polysomnography, which is an overnight sleep study that monitors various physiological parameters, including brain activity, breathing patterns, heart rate, and body movements. By analyzing the data collected during sleep, a sleep specialist can identify the characteristic features of catathrenia and rule out other potential sleep disorders. Keeping a sleep diary and recording the nocturnal vocalizations can also aid in the diagnostic process and provide valuable information about the frequency and intensity of the groaning episodes.
Management of catathrenia aims to reduce the frequency and impact of the nocturnal groaning episodes. While there is no cure for this sleep disorder, certain treatments can help improve symptoms and promote more restful sleep. Cognitive-behavioral therapy for insomnia (CBT-I) is often recommended to help individuals manage their sleep habits and address any underlying anxiety or stress that may be contributing to the disorder. Relaxation techniques, such as deep breathing or meditation, can also assist in reducing muscle tension and promoting a calm state before sleep, which may lessen the intensity of catathrenia episodes.
In some cases, medication may be prescribed to help regulate sleep and reduce the occurrence of groaning. These typically involve the use of muscle relaxants or sedatives to alleviate any underlying sleep disruptions that could be triggering the abnormal breathing patterns. However, medication is generally not the first line of treatment, and lifestyle modifications and behavioral therapies are usually the initial approach. Additionally, addressing any underlying sleep disorders or respiratory conditions can help improve catathrenia symptoms. Overall, raising awareness of this rare sleep disorder is crucial to ensuring that those affected receive an accurate diagnosis and effective management strategies.

The cause of catathrenia is not well understood, but research suggests it may be associated with an underlying sleep-associated breathing problem
Moaning in your sleep may be a symptom of a rare sleep disorder called catathrenia, or nocturnal groaning. Catathrenia is characterised by moaning, groaning, humming, or making cracking sounds while asleep. The cause of catathrenia is not well understood, but research suggests it may be associated with an underlying sleep-associated breathing problem.
Catathrenia is a sleep-related breathing disorder that causes moaning or groaning during sleep, typically during exhalation. The noise is described as loud and can last for a few seconds or up to about 50 seconds. It can occur during REM and non-REM sleep, and can happen nightly. The condition is often first noticed by a bed partner or family member, as the person sleeping may not be aware of their moaning.
While the exact cause of catathrenia is unknown, research suggests it could be due to malfunctioning or dysfunctional neurons in the part of the brain that controls breathing (the respiratory centre or medulla oblongata). These neurons cause prolonged exhalation, and the resulting vibration of the vocal cords creates the moaning or groaning sound. Other possible causes include small upper airways, small jaws, or inspiratory flow limitation, where airflow remains constant despite increased breathing effort.
Catathrenia is typically not harmful to the sleeper and is different from other breathing problems and sleep disorders. However, it can cause social embarrassment and impact self-esteem. Treatment options are available, including CPAP therapy, oral appliances, and surgery. A sleep study, or polysomnography, can help confirm the diagnosis and rule out other conditions.

Moaning in your sleep may be a symptom of a rare sleep disorder called catathrenia, or nocturnal groaning. Catathrenia involves moaning, groaning, or making other strange noises during sleep, typically during exhalation. The exact cause of catathrenia is not well understood, but researchers suspect that it may be caused by a variety of factors, including neurological dysfunction in the part of the brain that controls breathing.
Catathrenia is characterized by loud moaning or groaning sounds that occur during sleep, usually during exhalation. These sounds can last from a couple of seconds to up to 40 or even 50 seconds. The condition can be disturbing to bed partners or roommates due to the loud nature of the noises. While catathrenia is not considered harmful to the sleeper, it can cause social embarrassment and self-esteem issues.
One proposed cause of catathrenia is dysfunctional neurons or nerve cells in the part of the brain that controls breathing, known as the respiratory center or medulla oblongata. These malfunctioning neurons cause prolonged exhalation, resulting in the vocal cords vibrating and creating the characteristic moaning or groaning sounds associated with catathrenia. This neurological dysfunction may be one of the key factors contributing to the disorder.
In addition to neurological factors, physical attributes may also play a role in catathrenia. Some individuals with catathrenia may have small upper airways or small jaws, which can contribute to breathing abnormalities during sleep. Additionally, inspiratory flow limitation, where airflow remains constant despite efforts to breathe more deeply, has been observed in people with catathrenia. These physical attributes may further exacerbate the breathing disturbances experienced during catathrenia episodes.
Treatment options are available for catathrenia, including CPAP therapy, oral appliances, and surgical interventions. CPAP therapy involves using a machine and mask to deliver pressurized air into the airway, keeping it open and reducing the occurrence of groaning. Oral appliances, such as mandibular advancement devices (MADs), are custom-made dental appliances that reposition the lower jaw forward, increasing upper airway space and reducing nighttime groaning. Surgical options, such as tonsillectomy or adenotonsillectomy, can also be considered, especially when combined with CPAP therapy or oral appliances.

Treatments for catathrenia include CPAP therapy, mandibular advancement devices, tongue-retaining devices, and surgery
Moaning in your sleep, or catathrenia, is a rare sleep-related breathing disorder characterised by groaning sounds during exhalation. It usually occurs during the REM stage of sleep. Treatments for catathrenia include:
CPAP Therapy
CPAP (continuous positive airway pressure) therapy uses a machine and mask to deliver pressurised air into a person's airway, keeping it open at night and reducing the chance of snoring and groaning. CPAP therapy can improve sleep quality, reduce daytime sleepiness, and minimise the occurrence of long moaning episodes during non-REM sleep.
Mandibular Advancement Devices (MADs)
MADs are custom-made dental appliances designed to reposition the lower jaw forward, increasing upper airway space and reducing nighttime groaning caused by obstructive sleep apnea. They work by pulling the base of the tongue forward, creating more space in the back of the throat.
Tongue-Retaining Devices (TRDs)
TRDs hold the tongue in place using suction, preventing it from falling back into the throat during deep breathing exercises or REM sleep cycles. This can help alleviate catathrenia symptoms associated with upper airway obstruction.
Surgery
Tonsillectomy and adenotonsillectomy are surgical options that involve removing the tonsils or both the tonsils and adenoids. These surgeries are especially effective when combined with CPAP therapy or an oral appliance.

Moaning in your sleep may be a symptom of a rare sleep disorder called catathrenia, or nocturnal groaning. Catathrenia 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-associated breathing problem. It is characterised by loud moans and noises produced during sleep, which can last for a couple of seconds or up to 40 to 50 seconds. The disorder usually occurs during the REM stage of sleep and is often first noticed by bed partners or family members rather than the person with catathrenia themselves.
Catathrenia can cause social problems, as the loud noises can disturb others and disrupt their sleep. It can be embarrassing for the person with catathrenia, leading to self-consciousness and social anxiety. It is recommended that those experiencing catathrenia speak openly about the issue with their bed partners or roommates. This can help address any concerns or embarrassment and allow both parties to find suitable solutions. For example, earplugs can be an effective way for bed partners to block out the noise and improve their sleep quality.
If catathrenia is causing significant disruption to the sleep of others, it is important to seek advice from a healthcare provider. Treatment options are available, such as CPAP therapy, oral appliances, and surgical interventions, which can help reduce the symptoms and improve sleep quality for both the person with catathrenia and those they share a bed with.
Additionally, speaking with a mental health professional can be beneficial if the symptoms of catathrenia are affecting an individual's self-esteem and social interactions. It is important to remember that catathrenia is not considered dangerous or harmful to the sleeper and that treatment options are available to manage the symptoms effectively.
While catathrenia is a rare disorder, it is important to seek help if it is causing social problems or disrupting the sleep of those around you. Open communication and seeking appropriate treatment can help minimise the impact of catathrenia on your social life and relationships.
