Can fright cause a mark drop in blood pressure?

Yes, fright can cause a marked drop in blood pressure. This is because when a person is frightened, the body's sympathetic nervous system is activated, which leads to an increase in heart rate and blood pressure. However, if the fear is very intense, the parasympathetic nervous system can be activated, which leads to a decrease in heart rate and blood pressure. This can sometimes cause a person to faint.
