There are many reasons why a 22-year-old might die in their sleep. One of the most common causes of nocturnal death is sudden cardiac arrest, which accounts for roughly 22% of such deaths, according to a 2021 study. Other causes include congestive heart failure, stroke, terminal illnesses such as lung failure, seizures, drug overdoses, carbon monoxide poisoning, and sleep disorders such as sleep apnea. Additionally, certain underlying conditions, such as obstructive sleep apnea (OSA), can increase the risk of dying in one's sleep. In some cases, individuals may have undiagnosed heart conditions or sleep disorders that contribute to their susceptibility to nocturnal death. While the exact causes of nocturnal death are varied and complex, understanding the risk factors and warning signs can help individuals and healthcare providers manage potential health risks.

What You'll Learn
Heart problems, such as cardiac arrest, heart attack, or arrhythmia
Sudden cardiac arrest is among the most common causes of nocturnal death, with 22% of cases occurring between 10:00 p.m. and 6:00 a.m. according to a 2021 study. Heart attack, heart arrhythmia, congestive heart failure, and stroke can all lead to sudden cardiac arrest.
Heart failure means the heart is less able to pump blood efficiently, and death may occur years after diagnosis. With sudden cardiac death, the heart stops completely, and death can occur within minutes. Heart attacks, or myocardial infarctions, occur when a blood vessel supplying the heart muscle becomes obstructed, and the tissue supplied is damaged or dies. Warning signs include chest pain, sweating, breathlessness during activity, and heightened fatigue.
Arrhythmias, or irregular heart rhythms, can lead to sudden cardiac arrest, especially if not properly managed. Certain arrhythmias, such as Long QT syndrome, have been linked to cases of Sudden Unexplained Nocturnal Death Syndrome (SUNDS). Additionally, irregular heart rhythms may lead to a clot that travels to the brain and causes a stroke, which may be fatal and can occur during sleep.
Sudden cardiac arrest in young people can be caused by various factors, including inherited heart conditions, structural heart abnormalities, underlying health conditions, and lifestyle choices. Regular medical check-ups and a healthy lifestyle can help reduce the risk of sudden cardiac arrest.

Terminal illnesses, including lung failure
Other terminal illnesses or conditions that can cause death during sleep include sudden cardiac arrest, which is among the most common causes of nocturnal death. This can be caused by a heart attack, heart arrhythmia, congestive heart failure, or a stroke. Warning signs may include chest pain and sweating. Additionally, certain underlying conditions, such as obstructive sleep apnea (OSA), can increase the risk of dying in one's sleep.
It is important to note that the length of sleep can also impact mortality rates. Studies have shown that both short and long sleep durations are associated with increased mortality risks. For example, in men, short sleep was significantly associated with an increased risk of natural death across all ages, with the youngest group showing a 96% increase in risk. Similarly, long sleep durations were associated with a significant increase in risk for older men.
While the exact causes are often unknown, sudden arrhythmic death syndrome (SADS) has been observed in seemingly healthy young adults, particularly among certain cultural and genetic groups. For example, Laotian Hmong refugees in the United States and Thai foreign workers in Singapore have been found to have higher rates of SADS. Cultural beliefs and displacement, resulting in a lack of access to spiritual protection, have been suggested as potential factors contributing to these deaths.
In summary, terminal illnesses, such as lung failure resulting from long-term lung conditions, can lead to death during sleep. Additionally, underlying conditions and the length of sleep can impact the risk of nocturnal death. Furthermore, cultural and genetic factors may play a role in sudden arrhythmic death syndrome, particularly in specific populations.

Seizures, drug overdoses, or carbon monoxide poisoning
Seizures, drug overdoses, and carbon monoxide poisoning are potential causes of nocturnal death, often without warning.
Seizures are a common cause of nocturnal death for people with epilepsy. Sudden Unexpected Death in Epilepsy (SUDEP) is the sudden, unexpected death of someone with epilepsy who was otherwise healthy. People with tonic-clonic seizures (grand mal) are at the greatest risk of SUDEP. Those with night-time seizures may also be at higher risk. In many cases, there are signs that the person had a seizure before dying, such as being found lying face down or evidence of a recent seizure. However, this is not always the case, and it is not a requirement for a SUDEP diagnosis. The cause of SUDEP is not yet known, but research suggests it may be related to problems with breathing, heart rhythm, and brain function that occur with a seizure. For example, a seizure can cause a person to briefly stop breathing (apnea), which may lead to death.
Drug overdoses are another potential cause of nocturnal death. Sleeping pills, in particular, can be dangerous if taken in high doses or if a person increases their dosage without medical advice. While modern formulas are generally safer and less potent than older pills, they can still be a threat and lead to death in high doses. Parasomnias, or complex sleep behaviors, are another potential side effect of sleeping pills. These are movements, behaviors, and actions that a person does while asleep and are unaware of, such as sleepwalking. While rare, parasomnias can be harmful and are more likely to occur with higher dosages.
Carbon monoxide poisoning is also a potential cause of death in one's sleep, although it is not as common as other causes like sudden cardiac arrest. Carbon monoxide is a toxic gas that can build up in a home due to faulty heating systems or other appliances that use gas, oil, wood, or coal.

Sleep disorders, such as sleep apnea or sleepwalking
Sleep disorders can have serious consequences for one's health, and in some cases, they can even lead to death. Obstructive sleep apnea (OSA), for instance, can increase the risk of dying in one's sleep. This condition occurs when the upper airway muscles relax during sleep, blocking the airway and preventing adequate breathing. Individuals with OSA may experience frequent breathing pauses lasting 10 seconds or longer, disrupting their sleep and depriving their body of sufficient oxygen.
The severity of OSA can range from mild to severe, depending on the number of breathing pauses experienced per hour, as measured by the apnea-hypopnea index (AHI). Severe OSA is characterised by an AHI greater than 30, indicating more than 30 breathing pauses per hour. Even mild OSA, with an AHI between 5 and 15, can have detrimental effects. Untreated OSA can lead to long-term health issues, particularly related to cardiovascular and metabolic health. The frequent interruptions in breathing can cause oxygen deprivation, leading to high carbon dioxide levels and low blood oxygen levels, which can have severe consequences, especially for those with underlying heart conditions.
OSA is quite common, affecting about 3% of individuals with normal weight and over 20% of obese people. However, it often goes undiagnosed, as some people may experience OSA without noticeable snoring or other typical symptoms. When left untreated, OSA can increase the risk of stroke, cardiovascular disease, and even death. Therefore, it is crucial to recognise the signs and symptoms of OSA, which may include unexplained fatigue, mood swings, dry mouth, and headaches upon waking.
Another rare sleep disorder that can be fatal is fatal insomnia (FI). This extremely rare neurodegenerative disease is characterised by a complete inability to sleep, followed by rapid weight loss and dementia. The final stage of FI involves a state of unresponsiveness or muteness, ultimately leading to death. The disease typically progresses over a few months to a few years, and currently, there is no known cure or disease-modifying treatment. Fatal insomnia is often hereditary, associated with a mutation in the PRNP gene, and can affect individuals between the ages of 13 and 60.

Genetic conditions, like familial dysautonomia, or sudden arrhythmic death syndrome
There are several underlying genetic conditions that can cause nocturnal death. One such condition is familial dysautonomia, a genetic disorder that affects the development and survival of nerve cells in the autonomic nervous system, which controls involuntary actions such as digestion, breathing, and the regulation of blood pressure and body temperature. The disorder is caused by mutations in the ELP1 gene, which provides instructions for making a protein found in a variety of cells, including brain cells. Familial dysautonomia primarily affects individuals of Ashkenazi Jewish descent, with about 1 in 3,700 individuals in these populations affected. Symptoms typically appear during infancy and include poor muscle tone, feeding difficulties, and frequent lung infections. While some individuals with familial dysautonomia may show no signs of developmental delay, others may experience delays in reaching milestones such as walking and speaking.
Another genetic condition that can lead to death during sleep is sudden arrhythmic death syndrome (SADS). SADS is the sudden and unexpected death of adolescents and adults caused by cardiac arrest, although the exact cause of the cardiac arrest is often unknown. SADS occurs mainly during sleep or when the individual is at rest. It is rare in most parts of the world but has been observed more frequently in certain culturally and genetically distinct populations, such as Southeast Asian immigrants and their descendants. SADS is often associated with inherited heart disease, and families with a history of genetic cardiac disease are at a higher risk. In a 2008 study, it was found that over half of SADS deaths could be attributed to conditions such as long QT syndrome, Brugada syndrome, and arrhythmogenic right ventricular cardiomyopathy.
Additionally, fatal insomnia, an extremely rare neurodegenerative prion disease, can also lead to death during sleep. Fatal insomnia is characterised by worsening insomnia, resulting in panic attacks, paranoia, and phobias. As the disease progresses, individuals may experience speech problems, coordination problems, and dementia. Fatal insomnia can be detected prior to onset by genetic testing, and there is currently no known disease-modifying treatment.

Frequently asked questions
There is no statistical data on the probability of a 22-year-old dying in their sleep. However, a study found that the risk of mortality increases by 96% for young men who sleep for less than 7 hours a night.
One of the most common causes of nocturnal death is sudden cardiac arrest, which accounts for roughly 22% of deaths between 10:00 pm and 6:00 am. Other causes include congestive heart failure, stroke, lung failure, seizures, drug overdoses, carbon monoxide poisoning, and sleep apnea.
Sudden cardiac arrest occurs when the heart suddenly stops beating. It can be caused by a heart attack, heart arrhythmia, or congestive heart failure. Warning signs may include chest pain, dyspnea, and syncope.
SADS is a rare syndrome that primarily affects young Hmong men from Laos and Thailand. It was first noted in 1977 among Laotian Hmong refugees in North America. The exact cause of death is unknown, but it is believed to be related to cardiac arrest and abnormal heart rhythms.
It is important to discuss your concerns with a healthcare provider, who can assess your individual risk factors. If you are experiencing sleep disorders or anxiety about sleeping, it is recommended to seek professional help to improve your sleep quality and manage your health risks.
