Fainting (also known as syncope) is a short-term loss of consciousness, usually for less than one minute.

Causes of Fainting, Blackout, Lightheadedness, Syncope
Fainting is usually caused by a momentary loss of blood flow to the brain. The four most common causes are sudden stress (such as witnessing a traumatic event), extreme pain, standing in one position for a long period of time, or suddenly standing up from a sitting or prone position. Falling or lying down usually improves the flow of blood to the brain.
