A nosebleed happens when one of the blood vessels in the lining of the nose bursts. Nosebleeds may be caused by infection, injury, allergic reaction, nose picking or an object being pushed into the nostril. Another name for nosebleed is epistaxis. Bleeding from the nose is common in children and is usually not serious. Seek medical attention if nosebleeds are severe, frequent or prolonged.
Common causes of nosebleeds include: 1  Dry, heated, indoor air, which dries out the nasal membranes and causes them to become cracked or crusted and bleed when rubbed or picked or when blowing the nose (more common in winter months) 2  Dry, hot, low-humidity climates, which can dry out the mucus membranes.
