The most common causes are dryness (often caused by indoor heat in the winter) and nose picking. These two things work together--nose picking occurs more often when mucus in the nose is dry and crusty. \n\nOther, less common, causes include injuries, colds, allergies or cocaine use. Children may stick small objects up the nose. Older people may have atherosclerosis ("hardening of the arteries"), infections, high blood pressure and blood clotting disorders, or they may be taking drugs like aspirin that interfere with blood clotting. The cause of nosebleeds often can't be determined. \n\nTips on preventing nosebleeds include:\nkeep the lining of your nose moist: Gently apply a light coating of petroleum jelly (brand name: Vaseline) inside your nose with a cotton swab twice a day. \nKeep children's fingernails short to discourage nose picking. \nCounteract the drying effects of indoor heated air by using a humidifier at night in your bedroom. \nQuit smoking. Smoking dries out your nose and also irritates it. \nOpen your mouth when you sneeze.

This site answers your question perfectly:\n\nhttp://www.nlm.nih.gov/medlineplus/ency/article/002914.htm\n\nThey give several reasons for this including dehydration, post nasal drainage and overproducing tears.  Check out the link above....

They are usually nothing to be alarmed about.  Get a humidifier and/or vaporizer.  My nephew gets them.\n\nSaline spray is supposedly a good thing too.\n\nPinch for 10 minutes is the recommended solution I believe.  \n\nhttp://en.wikipedia.org/wiki/Bloody_nose\n\nBeware, the picture isn't pretty.

My daughters nose would bleed like that too and the doctor said it was sinus problems and allergies. She used to get these huge clots too that would scare me to my wits end! She still gets them occasionally but it's not as frequent as before.

It bleeds because your nose is dry and has no moister in it. Just like any cut just apply pressure and after apply some Vaseline to it. That helps to prevent it.

Very likely a mask squeeze. As you descend, you have to allow a little air into your mask (through your nose). If not it will be pressed tightly against your face as a relative vacuum is generated between the outside water pressure and the partially equalized pressure within the space enclosed by the mask. This can cause small vessels to rupture leading to bruising, black eyes, ruptured vessels of the sclera of the eye and nose bleeds.

they can cauterize your blood vessels in your nose, which will help prevent nosebleeds.  My brother gets them a lot, because we live in the desert, and the air is really dry.  One thing that helps is if you put a Q-tip into a jar of Vaseline (or maybe put Neosporin on it) and then swab the insides of your nose every morning and night.  It really helps.  I used to get nosebleeds a lot when I was on a medicine called Accutane (it dries your whole body out really bad -- it's for acne), and I used to do that.

Because your nose is not very clean.  Try cleaning your nose out and u might see a difference.

This problem can be caused by a virus or bacteria, by polyps or swelling in the nasal conchae, by overuse of nasal sprays (which destroy the nasal lining, ultimately).  Irritants from tobacco smoking are a common cause also.  An antibiotic may be necessary - Amocycillin is the AB of choice. Truly chronic rhinitis /sinusitis requires physical examination (to exclude polyps etc) - and may be cured by a simple op to help the cavities to drain.  (Nurse 'Creamcheese').

BLOW!!!! You have to blow your nose. what are you gonna do just let it run down your face???? If you do not get the mucus out of your nose and sinuses then it will make you worse. you could even get a sinus infection and wind up in the hospital with your eye bulging out of your head because the pressure from the infection is so strong that is what happened to my friend.

my daughter had nose bleeds more then 10 times a month.  this has been going on for a few years a doctor put her on nasonex and it worked for a while.  two weeks ago i took her to a specialist and he cauterized it.  said her blood vessel were not cover by any thing and just moving the wrong way would make it bleed.  has only had one bad one and that was the day she had it done.  had a few little ones the next few days after but has been good since.  if i were you i would get to the doctors. cuz my friends mom started doing it and they said she has hi blood pressure.

Use a moisturizing saline nasal spray, you can get it at any pharmacy, or you can apply a small amount of Vaseline with a Q-tip to the inside of your nose. If the nose bleeding persists, contact your doctor, it could be something more serious.

I had this problem associated with a sore throat and nose bleed. Turned out the air in my room was to dry, so I put a humidifier on at night, drink plenty of water before I go to bed and keep a glass of water on my night stand. If it dosen't clear up in a week or two you may want to see a doctor.

Um, the first answer is completely wrong.\n\nTo stop the nosebleeds when they happen, pinch the top of the nose, DO NOT lean the head back, hold a cool rag or better yet a piece of ice under the bottom lip.\n\nGo see your doctor to keep it from happening all the time.

It is probably a cracked vein due to the dry air but you can get a satisfactory answer from an ENT doctor since he will suggest you to have the necessary blood tests done in order to find out what is wrong. I think it is the most satisfactory solution for your worries about your health.\n\nCheck out ;\nhttp://www.ctds.info/nose_bleeds.html\n\nhttp://menshealth.about.com/od/conditions/a/nose_bleeds.htm
