IT SEEMS to be common knowledge that the proper way to stop a nosebleed is to look up while pinching the bridge of your nose. Verdict:FALSELooking up or lying down while having a nosebleed will only cause the bleeding to go back down your throat and potentially into your lungs or stomach. According to the Health Ministry, the proper way to deal with a nosebleed is to sit down and lean forward with your head tilted forward. You should then pinch your nose just above your nostrils for 10 to 15 minutes and breathe through your mouth. This will allow the bleeding to exit via your nose rather than flowing back down your throat.
