Sleep apnea is a common condition that causes people to stop breathing intermittently while asleep. It can be caused by a blockage of the airway or a problem in the brain stem, which fails to send the proper signals to the muscles that control breathing. While sleep apnea itself is extremely unlikely to cause death, it can lead to serious health complications, including heart attacks, strokes, and cardiac arrest. Other causes of suffocation during sleep include choking on food or vomit, carbon monoxide poisoning, and seizures. In rare cases, people may also experience sleep-related choking due to a medical problem or a dream.
| Characteristics | Values |
|---|---|
| Causes of suffocation | Choking on food or a throat lozenge, inhaling vomit after a seizure or alcohol consumption, obstructive sleep apnea, congenital disorders, heart failure, narcotic medication use, brainstem injuries, carbon monoxide poisoning, and more |
| Effects of suffocation | Lack of oxygen, increased carbon dioxide levels, irregular breathing patterns, choking, gasping for air, increased heart rate and blood pressure, cardiac arrhythmia, atrial fibrillation, stroke, heart attack, and potential sudden death |
| Prevention and Treatment | Seek medical evaluation, continuous positive airway pressure (CPAP) machines, oral appliances, and other treatment options |

What You'll Learn
Choking on food or vomit
Certain health conditions can also increase the risk of choking in your sleep, such as obstructive sleep apnea (OSA). OSA can exacerbate other medical conditions that may ultimately be fatal, including strokes, heart attacks, heart failure, and arrhythmias. Additionally, conditions such as acid reflux, GERD, sinusitis, or pregnancy can cause vomiting in one's sleep.
To prevent choking on food or vomit while sleeping, it is recommended to avoid eating a large meal or fatty foods before bedtime. Eating smaller meals, eating slowly, and taking a walk after a meal can aid digestion and reduce the risk of vomiting. Losing weight and exercising moderately can also help reduce the risk of choking for those with GERD or sleep apnea, as excess weight increases abdominal pressure and makes stomach acid backflow more likely.
Adopting healthier sleeping positions can also help reduce the risk of choking. Sleeping on one's back can make it easier for stomach acid to flow back into the esophagus, leading to potential choking. Sleeping on an elevated surface, such as a mattress wedge or tilter, can help keep stomach acid down and reduce the chances of choking on vomit.
While it is uncommon to choke to death while sleeping, it is important to be aware of the risk factors and take preventative measures to ensure a safe and comfortable sleep.

Sleep apnea
There are two main types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is the most common type and occurs when the upper airway becomes blocked many times while the person sleeps. This blockage can reduce or completely stop airflow. OSA can be caused by factors such as obesity, large tonsils, changes in hormone levels, age, sex, body weight, and certain anatomical features of the head and neck area. CSA occurs when the brain fails to send the signals needed to breathe. CSA often occurs as a consequence of another medical problem, such as an infection or injury affecting the brain stem.
The symptoms of sleep apnea include loud snoring, daytime sleepiness, headaches, and gasping for air during sleep. Sleep apnea can lead to issues with concentration, decision-making, memory, and behaviour control. It can also increase the risk of serious health problems such as stroke, heart attack, and heart failure.
If you suspect you may have sleep apnea, it is important to consult a healthcare provider. Diagnosis of sleep apnea can be made through a sleep study or a home sleep test. Treatment options include the use of breathing devices such as continuous positive air pressure (CPAP) machines, lifestyle changes, and in some cases, surgery.
While it is not common to suffocate in your sleep, certain conditions such as sleep apnea can increase the risk of choking during sleep. Additionally, choking can occur if a person vomits during a nighttime seizure or after consuming too much alcohol, or if they fall asleep with food or a throat lozenge in their mouth.

Heart attack
While it is possible to choke or suffocate in your sleep, this is usually due to inhaling food or a throat lozenge, or as a result of a seizure or excessive alcohol consumption. Obstructive sleep apnea (OSA) can also cause fatal asphyxiation, though this is rare.
Now, onto the details of how heart attacks relate to suffocation in sleep.
A massive heart attack can reduce blood flow to the part of the brain that controls breathing, leading to respiratory arrest, and ultimately, death. This can also place excessive strain on the heart, causing it to progressively fail.
Sudden cardiac arrest, or SCA, can occur when the sinoatrial node, the body's natural pacemaker, becomes impaired. This reduces blood flow to the brain and can be deadly within minutes.
In summary, while it is possible to suffocate in your sleep, this is usually due to external factors or underlying conditions. Heart attacks can also occur during sleep, but they usually wake the victim before causing death. However, in some cases, a heart attack can cause respiratory arrest and subsequent heart failure, leading to death.

Carbon monoxide poisoning
It is possible to choke or suffocate in your sleep, and this can be caused by vomiting during a seizure or after consuming too much alcohol, or by inhaling food or a throat lozenge. Obstructive sleep apnea (OSA) can also increase the risk of choking in your sleep.
Carbon monoxide (CO) is an odorless, colourless gas produced when fossil fuels are burnt. It is often produced by common household items, such as gas- and oil-burning furnaces, portable generators, and charcoal grills. It is also found in the fumes from burning fuel in cars, trucks, and other vehicles. CO poisoning can cause sudden illness and death, but it can be prevented.
CO is dangerous because it can build up indoors and poison people and animals who breathe it. The gas is especially harmful during sleep, as the risk of death is higher due to the delayed emergency medical response. People who are sleeping may die from CO poisoning before they experience any symptoms. Infants, the elderly, and those with chronic heart disease, anemia, or breathing problems are at a higher risk of getting sick from CO poisoning.
The initial symptoms of CO poisoning include severe headache, nausea, weakness, confusion, heart arrhythmias, myocardial infarction, coma, or death. CO poisoning affects the basal ganglia and subcortical white matter in the brain, causing damage to the cerebral regions that regulate heart rate variability. Studies have shown that survivors of CO poisoning may develop diverse neuropsychological sequelae and experience a decrease in cognitive performance.
To reduce the risk of CO poisoning, it is recommended to install battery-operated or battery-backed-up CO detectors near every sleeping area. These detectors should be checked regularly, and replaced according to the manufacturer's instructions or every 5 years.

Drug overdose
A drug overdose occurs when an individual takes more of a substance than their body can handle. This can lead to a range of dangerous and even life-threatening consequences. Overdose is always considered a medical emergency and can result in serious health complications or even death.
Sleeping pills, for example, can cause overdose when taken in excess or in combination with other substances. Sleeping pills are classified as "sedative hypnotics," acting upon the central nervous system (CNS) as depressants to slow down the body's functions and aid sleep. Common sleeping pills include barbiturates and benzodiazepines, which can be highly addictive and are among the leading causes of drug overdose deaths. Mixing sleeping pills with opioids or alcohol can increase the risk of overdose and enhance the depressive effects on the body's systems, including respiratory failure and death.
Prescription medications, such as Ambien, Lunesta, and Sonata, are also commonly associated with overdose risks. Taking higher doses than prescribed or combining them with other substances can lead to dangerous outcomes. It is important to carefully follow the dosage instructions provided by a physician, as misuse or abuse of these drugs can have fatal consequences.
Opioids are another class of drugs that can lead to overdose when taken in excess or combined with other substances. Opioids affect the part of the brain that controls breathing, and an overdose can cause a person's breathing to slow down or even stop, resulting in unconsciousness or death. Illegal opioids, such as fentanyl, pose an even greater risk as their strength and composition are often unknown.
It is crucial to seek immediate medical assistance in the event of a suspected overdose. Emergency services should be contacted, and supportive care is typically provided to monitor the patient's vital signs while their body recovers from the overdose. In some cases, specific treatments such as activated charcoal, hemodialysis, or medication like flumazenil may be administered to counter the effects of the overdose.
