Moaning in your sleep can be a symptom of catathrenia, a rare sleep disorder that causes you to moan, groan, hum, or make other strange noises while exhaling during sleep. The cause of catathrenia is not well understood, but it is believed to be related to individual factors such as dysfunctional neurons in the brain, small upper airways, small jaws, and limited airflow upon exhale. Catathrenia can be a source of embarrassment and social discomfort for those who experience it, and it can also disrupt the sleep of bed partners or roommates due to the loud noises produced. Treatment options are available, including CPAP therapy, oral appliances, and surgery, to help reduce symptoms and improve sleep quality for both the affected individual and their bed partner.

What You'll Learn
Catathrenia, a sleep disorder
Catathrenia, a rare sleep disorder, is characterised by moaning or groaning during sleep. The disorder is believed to be benign and non-life-threatening. The exact cause of catathrenia is unknown, but it is classified as a sleep-related breathing disorder. It occurs when a person exhales and stops when they inhale. The moaning or groaning sounds can last from a few seconds to a minute, often repeating in clusters for 2 minutes to 1 hour, and may recur many times per night. It can happen during REM and non-REM sleep.
The primary symptom of catathrenia is an almost nightly moaning or groaning sound during sleep that the sleeper does not realise they are making. The sound is often monotone and may be perceived as sullen, gloomy, or sexual in nature. The disorder usually affects the bed partner, roommate, or family member who hears the noises, rather than the person with catathrenia.
The exact cause of catathrenia is unknown, but research suggests it could be due to malfunctioning neurons (nerve cells) in the brain at the respiratory centre (medulla oblongata). These neurons cause prolonged exhaling, and when the person exhales, their vocal cords vibrate to create a moaning or groaning sound. Catathrenia has also been found to co-occur with Parkinson's disease.
Treatment options are available to reduce catathrenia symptoms and help both the affected person and their sleeping partner sleep better. These include CPAP therapy, oral appliances, and tonsillectomy surgeries. Sleeping in a more upright position and performing regular aerobic exercise that involves steady breathing (e.g., running, cycling) may also help lessen catathrenia symptoms.

Social embarrassment
Moaning in your sleep can be a symptom of catathrenia, 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 related to individual factors such as dysfunctional neurons in the part of the brain that controls breathing, small upper airways, small jaws, or inspiratory flow limitation.
Many people feel socially embarrassed by their sleep moaning, especially when it disturbs others. This can lead to feelings of self-consciousness and social anxiety. Some people try to hide or interrupt their moans, feeling a sense of relief when they sleep alone or in private spaces. The social embarrassment associated with sleep moaning can be a source of significant distress and impact one's willingness to share sleeping spaces with others.
To manage social embarrassment related to sleep moaning, it is essential to recognize that it is a common and harmless condition. Catathrenia is often first brought to attention by bed partners or roommates, and it is more of a social nuisance than a medical concern. While it can be an awkward topic to address, open communication with those you share a sleeping space with can help alleviate embarrassment and lead to understanding and collaboration in finding solutions.
Treatment options are available to reduce the symptoms of catathrenia and improve the quality of sleep for both the affected individual and their bed partner. These include CPAP therapy, oral appliances, and, in some cases, surgery. Seeking professional help from a healthcare provider or a mental health professional can be beneficial in managing both the physical and psychological impacts of sleep moaning.
Additionally, some simple solutions can help minimize social embarrassment. For example, affected individuals can sleep in separate rooms or warn their bed partners about their condition. Earplugs can also be an effective way for bed partners to block out unwanted noise and improve their sleep quality.

Diagnosis and treatment
Moaning in sleep, also known as catathrenia, is a rare sleep-related breathing disorder. It is characterised by moaning, groaning, or other strange noises during exhalation while asleep. The exact cause of catathrenia is unknown, but it is believed to be related to malfunctioning neurons in the brain's respiratory centre.
If you are experiencing persistent moaning or groaning during sleep, it is recommended that you seek medical advice. A doctor will likely conduct a thorough evaluation, including a review of your medical history and possibly a physical examination. They may also recommend a sleep study to confirm the diagnosis of catathrenia. Treatment options are available and can be tailored to individual needs. These may include:
- Lifestyle modifications: Addressing underlying medical conditions, managing stress and anxiety, and practising stress-reducing techniques such as mindfulness, meditation, or yoga can help alleviate anxiety that may contribute to moaning during sleep. Cognitive Behavioural Therapy for Insomnia (CBT-I) is a structured program that can help identify and replace thoughts and behaviours that cause or worsen sleep problems.
- Therapeutic interventions: Treatment options such as Continuous Positive Airway Pressure (CPAP) therapy, oral appliances, and tonsillectomy surgeries have been used to improve sleep quality and reduce daytime sleepiness associated with catathrenia. Mandibular Advancement Devices (MADs) and Tongue Retaining Devices (TRDs) are also options to increase upper airway space and reduce nighttime groaning.
- Medication: Pharmacologic treatments such as clonazepam, trazodone, paroxetine, dosulepin (a tricyclic antidepressant), gabapentin, pramipexole, and carbamazepine have been anecdotally tried, although their effectiveness in controlling catathrenia is not yet fully understood.
- Communication and simple solutions: Catathrenia can significantly disrupt the sleep of bed partners or roommates. Open communication about the issue is essential, and simple solutions such as wearing earplugs can help minimise disruptions for those affected by the nocturnal groaning episodes.

Sleep apnea vs catathrenia
Moaning in your sleep could be a symptom of catathrenia, a rare sleep disorder that causes people to groan loudly in their sleep. The groaning sounds usually last between two and 49 seconds and occur during REM sleep, but they can also happen during non-REM sleep. Catathrenia is believed to be a sleep-related breathing disorder, although its exact cause is unknown. Treatments for catathrenia include CPAP therapy, oral appliances, and, in some cases, surgery.
Now, comparing catathrenia with sleep apnea:
Sleep Apnea
Sleep apnea is a common sleep disorder characterized by pauses in breathing during sleep, which can disrupt normal oxygen levels. It is often treated with continuous positive airway pressure (CPAP) therapy, which involves delivering pressurized air through a mask to keep the airway open during sleep. Sleep apnea is not believed to be directly associated with moaning or groaning during sleep, although it can cause snoring.
Catathrenia
Catathrenia, on the other hand, is a rare sleep disorder characterized by loud moaning or groaning during sleep. It is classified as a sleep-related breathing disorder, although its exact cause is unknown. People with catathrenia typically take a deep breath, hold it, and then slowly exhale with a high-pitched squeak or groaning sound. The disorder is often treated with CPAP therapy, oral appliances, and, in some cases, surgery.
In summary, both sleep apnea and catathrenia are sleep disorders that can impact breathing during sleep, and they may share some similar symptoms, such as disrupted breathing. However, the key distinction is that sleep apnea is primarily characterized by pauses in breathing, while catathrenia is defined by loud moaning or groaning during sleep. Treatments for both conditions may overlap, with CPAP therapy being a common intervention for both disorders.

Self-acceptance
Moaning in your sleep is nothing to be embarrassed about. In fact, it's a lot more common than you might think. The first step to self-acceptance is understanding the reason behind your sleep moaning. This will help you address any underlying issues and improve your sleep quality.
The medical term for moaning in your sleep is catathrenia, a rare sleep disorder characterised by strange noises during exhalation while asleep. It is believed to be caused by malfunctioning neurons in the brain's respiratory centre, which cause prolonged exhaling. When you exhale, your vocal cords vibrate, creating a moaning sound. Catathrenia can be differentiated from snoring as it comes from the larynx rather than the throat. It can also be mistaken for central sleep apnea, but the two conditions can be distinguished by the fact that catathrenia involves vocalisations, indicating ongoing breathing.
Catathrenia is not associated with any major complications and is considered a benign condition. However, it can disrupt your sleep and that of your bed partner. Treatment options are available, including CPAP therapy, oral appliances, and tonsillectomy surgeries. Lifestyle modifications, therapeutic interventions, and medication can also help alleviate the symptoms.
To improve your sleep quality, you can make changes to your sleep environment, such as maintaining a cool, dark, and quiet bedroom. Investing in a comfortable mattress, pillows, or a weighted blanket can also enhance your sleep posture and reduce anxiety. Establishing a consistent sleep schedule can help regulate your body's internal clock. Additionally, managing stress and anxiety through mindfulness, meditation, or yoga can prevent anxiety from contributing to moaning during sleep.
While moaning in your sleep may be a source of embarrassment, it's important to embrace it and laugh it off. Self-acceptance involves understanding that it's not your fault and that it's a common condition. By taking steps to improve your sleep quality and addressing any underlying issues, you can accept and embrace your sleep moaning.
