Why do we get nosebleeds?

Most nosebleeds come from the front of the nasal septum, an area called Little’s area or Kiesselbach’s plexus, where several small arteries meet near the surface. Dry air, especially in heated rooms during winter, dries and cracks the lining, making it vulnerable. Nose-picking, vigorous blowing, allergies and colds also irritate it. Children get nosebleeds more often because their blood vessels are closer to the surface. Most stop within 10 to 15 minutes by pinching the soft part of the nose and leaning slightly forward. Frequent or heavy nosebleeds can sometimes signal blood-clotting issues.
