Myth: Put your head back when you have a nosebleed. Fact: Don’t put your head back! Blood could flow down your throat and potentially into your stomach, which can cause nausea and vomiting; instead, tilt your head forward and pinch your nose right at your nostrils, not higher.
Hold your nose for a full 10 minutes before checking to see if the bleeding has stopped.
If bleeding lasts much longer or if the bleeding was the result of an injury, head to the emergency department.
