Feeling dizzy or fainting at the sight of a traumatic injury occurs as a result of parasympathetic overreaction that lowers blood pressure too much. The parasympathetic nervous system opposes the sympathetic nervous system and can cause a decrease in heart rate and blood pressure, leading to dizziness or fainting. This can happen in response to a strong emotional or physical stimulus such as the sight of a traumatic injury.
