I cut my finger and bled (not too bad) and almost fainted, BUT I am not afraid of blood, is this a vasovagal syncope response?

It’s a reaction to a trigger, most commonly the sight of blood triggers blood pressure to drop. Some think this is a defence mechanism to stop you from bleeding out faster, but the other effect it can have is a rise in heart rate, something that is counterproductive to bleeding out slower.

Syncope is a sudden loss of blood pressure, which often makes you pass out. The vagus nerve runs from your brain to your heart in order to slow the heart’s beating. So, a trigger in your brain sends a message down the vagus nerve to slow your heart, drop your blood pressure, and make you faint.
