What is Fainting?

Fainting occurs when there is a temporary reduction in blood flow to the brain, leading to a brief loss of consciousness. It can happen to anyone and is often triggered by factors such as stress, dehydration, or standing up too quickly. While it can be unsettling, fainting is usually not a cause for concern unless it happens frequently or is associated with other symptoms.
