Fainting is when someone briefly becomes unresponsive often causing them to fall to the ground. It happens because for a moment, there is not enough blood flowing to the brain.
People often faint as a reaction to pain, exhaustion, hunger, thirst, or emotional stress. It is also common for people to faint after they have been standing or sitting still for a long period of time and move too quickly, especially if they’re feeling hot.
