Why you shouldn't tilt your head back during a nosebleed

This incredibly common advice is practically a recipe for nausea. By tilting your head back, you aren't stopping the bleeding; you are just changing its direction. The blood flows right down your pharynx into your stomach, which severely irritates the gastric lining and often leads to vomiting up a terrifying puddle of blood. Lean slightly forward and pinch your nose like a normal person.
