A large proportion of deaths worldwide occur during sleep. The leading cause of death in sleep is sudden cardiac arrest.
This is a condition in which the heart stops unexpectedly during sleep. According to 2021 studies, about 22 percent of cardiac arrests occur between 10 pm and 6 am. It is more common in women than men.
A heart attack occurs when blood flow to the heart muscle is interrupted. Arrhythmia is a condition in which the heart beats irregularly. When the heart does not pump blood properly, it affects the function of the organs.
Death during sleep occurs due to congestive heart failure, breathing problems, obstructive sleep apnea, nervous system-related causes, stroke, epilepsy, and other physical accidents.
