You might be humming in your sleep due to Catathrenia (sleep-related groaning), a rare breathing disorder causing loud expiratory moans, or from intense dreams during REM sleep, where incomplete muscle relaxation allows vocalizations like humming, groaning, or talking to occur, often influenced by stress or emotions. While often harmless, it's best to see a doctor if it disturbs your sleep or others, as a sleep study can diagnose it, and treatments like CPAP or oral appliances can help.
Catathrenia is a sleep-related breathing disorder that causes moaning or groaning during sleep. The noise happens as you exhale. It's loud and lasts for a couple of seconds or up to 40 seconds. It can happen nightly, during REM and non-REM sleep.
Symptoms: People with the disorder inhale, stop breathing, then moan loudly as they exhale. Causes: Experts aren't sure if catathrenia is caused by small craniofacial structures, abnormal receptors in the brain, or something else.
Catathrenia is an exhalation sound similar to a whimper that occurs exclusively during sleep, especially REM sleep, and almost every night. The sound is loud and may disturb roommates. It is a little-known and relatively rare sleep disorder that is probably underdiagnosed.
Lamentations in the night: A systematic review on catathrenia. Catathrenia is a loud expiratory moan during sleep that is a social embarrassment and is sometimes confused with central apnea on polysomnography. It affects about 4% of adults, but cases are rarely referred to sleep centers.
Catathrenia is primarily identified by the distinctive groaning or moaning sounds made during sleep. These sounds typically occur during the REM (Rapid Eye Movement) stage of sleep and can last from a few seconds to over a minute. The groaning is often rhythmic and can occur multiple times throughout the night.
However, there are still some common signs that should prompt you to get checked and seek treatment for sleep apnea:
While babies often cry during sleep, many adults also experience this, especially during periods of emotional stress, vivid dreams, or underlying anxiety. Whether it's a one-time event or something that's been happening more often, crying in your sleep can be your body's way of processing deeper emotions.
Highlights. Sleep hypopnea is defined as a drop of ≥30% in breathing amplitude and in oxygen saturation >3% (AASMedicine), or >4% (CMMS). This study reveals a systematic bias, with the 3% criterion consistently yielding higher apnea/hypopnea index values.
Sinusitis. Because sinusitis causes inflammation throughout the human sinus cavity, this condition can mimic sleep apnea. Both conditions can cause snoring, gasping for air at night, breathing interruptions, and poor sleep quality.
How to Treat Catathrenia?
Although there is no association with risk of physical harm, catathrenia does present a significant cause for concern and anxiety among patients and their bed partners.
A groan is a sound of pain or disapproval that doesn't consist of words, usually heard after homework is assigned or bad jokes are told. People groan for lots of reasons: headaches, stomachaches, traffic jams, and bad news are just a few groan-worthy things that can provoke that moaning, "uuugghhhhh" sound.
These common behaviors and signs of sexsomnia include:
Constant humming can be associated with psychological conditions. It may signal anxiety or stress, where individuals hum as a means to self-soothe. Additionally, persistent humming might reflect underlying emotional states needing attention.
Signs of poor core sleep (deep, restorative sleep) include waking up foggy, daytime fatigue/energy crashes, poor concentration, irritability, frequent illness, memory issues, and mood swings, indicating your brain and body aren't fully repairing and consolidating memories. You might also experience increased sugar cravings, slow muscle recovery, and a weakened immune system.
The "3-2-1 Bedroom Method" (or a variation like the 10-3-2-1 rule) is a sleep hygiene strategy to improve rest by staggering when you stop certain activities before bed: stop heavy food/alcohol 3 hours before, stop work/mental stress 2 hours before, and turn off screens (phones, TVs, computers) 1 hour before sleep, creating a better wind-down for your body.
Talking in your sleep is a kind of parasomnia, or a disruptive sleep-related disorder that happens while you're sleeping. Unlike other parasomnias like sleepwalking or sleep-related eating disorder that can carry significant risks to your health and well-being, sleep talking usually has little to no risk.
Parasomnias are a type of sleep disorder that causes abnormal experiences or behaviors during sleep. These can happen as you're falling asleep, during sleep or right before you wake up. If you have a parasomnia, you might: Talk in your sleep. Sleepwalk.
Sleep apnea can occur at any age, but is most common between ages 2 and 8 during the period of peak tonsil growth. Children with sleep apnea typically aren't overweight and are developmentally appropriate, explains Dr. Reddy. However, obesity is a risk factor for sleep apnea in children.
You may have upper airway resistance syndrome (UARS). Upper airway resistance syndrome can be confused with sleep apnea, but they're not the same thing. Keep reading to discover why, if it's not sleep apnea, it could be upper airway resistance syndrome.
You have any of the main symptoms of sleep apnoea, such as: your breathing stops and starts while you sleep. you make gasping, snorting or choking noises while you sleep. you always feel very tired during the day.
