Dying in your sleep is rare, especially without serious health conditions. Doctors say most cases are linked to heart, lung, or brain problems, such as sudden cardiac arrest.
Other risks include untreated sleep apnea, uncontrolled blood pressure, epilepsy, and rare diabetes-related complications. Regularly sleeping far longer than average can signal underlying illness, not cause death.
Managing health conditions and getting routine checkups greatly lowers risk. For most people, sleep is safe and essential.
