Most people are used to tilting their head back when they have a nosebleed, but in fact this posture is not good for bleeding. 1.It will make the nasal cavity already flow backward to the throat due to the posture and gravity, which has no real effect on stopping the bleeding. 2.The blood from the throat will be swallowed into the esophagus and gastrointestinal tract, stimulating the gastrointestinal mucosa to produce discomfort or vomiting. 3. When the bleeding is large, it is also easy to aspirate and choke into the trachea and lungs, blocking the breathing airflow and causing danger. The correct method is – the head should be kept in a normal upright or slightly tilted forward position so that the blood that has flowed out of the nostrils is discharged so that it does not remain in the nasal cavity and interfere with the airflow of breathing.
