What happens in your body when you pass out?
A drop in blood flow to the brain causes fainting. The most common causes of fainting are usually not signs of a more serious illness. In these cases, you faint because of: The vasovagal reflex, which causes the heart rate to slow and the blood vessels to widen, or dilate.
Does your heart stop when you faint?
Less often, people faint suddenly, without any warning symptoms. Seizures, which are a disturbance of the brain’s electrical activity, and cardiac arrest, in which the heart completely stops beating, can cause loss of consciousness but are not considered fainting.
