"The doctor said I wouldn't have so many nosebleeds if I kept my finger outta there." - Ralph Wiggums, The Simpsons.
Ralph's doctor is right because too much nose picking is one of the main reasons kids get nosebleeds. So if a kid in class suddenly starts getting a bleeding nose - there's a pretty good chance he's been doing some serious nasal excavation. Nosebleeds are messy, look gross and can be uncomfortable - but they're really not a big deal.
What Causes Nosebleeds?
The most common type of nosebleed is an anterior nosebleed. That means it starts at the front part of the nose from one nostril. This happens when the tiny blood vessels that line the inside of your nose break. This can be caused if the vessels are scraped, ripped or irritated from nose picking, from being punched in the nose or from hitting your nose hard on something. Your blood vessels can also break if the lining of your nose gets dried out by really dry air.
