Nosebleeds are most common in boys and are often associated with colds or nasal allergies.
Vigorous exercise and blows to the nose can also cause nosebleeds. Excess blood irritates the stomach and causes vomiting. Time it by the clock and don t peek. If the student is only bleeding from one nostril, apply pressure just to that side. If bleeding continues after 5 minutes, hold nostril closed firmly for another 5 minutes.
