Since there are so many blood vessels in the nose and they are so close to the surface, they are relatively easy to injure and trigger a nosebleed, the American Academy of Pediatrics says.
Nosebleeds are most often caused by dryness in the air and nose picking. Colds, injuries, allergies and cocaine use can also lead to nosebleeds.
The academy mentions these preventive suggestions:
- Keep children’s fingernails short to discourage nose picking.
- Counteract the drying effects of indoor heated air by using a humidifier.
- Quit smoking. Smoking dries and irritates your nose.
- Open your mouth when you sneeze.
