There is a nerve named vagus which slows down the heart rate as well as blood pressure when it gets over stimulated. This can be triggered by the occurrence of excess fear, stress or any traumatic feeling.

When someone’s blood pressure falls below the normal level, that person may faint. As a matter of fact, dehydrated persons have a higher chance of fainting due to low blood pressure. Another condition that may cause fainting is called Orthostatic hypotension. It can occur to a person when a person has to stay in a room with high temperature or when he stands up too fast.
