When the air gets cold and dry, like in winter time, it makes nosebleeds more likely. Children are the most susceptible. Fortunately, there are easy tips for handling and even preventing your child's nosebleeds.

In most cases, a nosebleed occurs because the tiny vessels inside the nose have broken. This type of nosebleed, called an anterior nosebleed, occurs because the blood flows out of the front (or anterior) part of the nose.

These types of nosebleeds are usually not serious and generally stop by themselves or require only simple steps to stop the bleeding. They rarely require medical attention. Anterior nosebleeds are almost always a result of an irritation inside the nose caused by several factors, including:

  • Extremely cold and/or dry air, which dries out the mucous membranes of the nose
  • Dust, pollen, or other allergens
  • Frequent or forceful blowing of the nose or picking the nose
  • Foreign objects placed inside the nose
  • A blow to the nose
  • Inflammation due to the common cold or flu
  • Chronic use of nasal steroids

Posterior nosebleeds, on the other hand, are much less common and occur when the blood flow comes from deep inside the nasal cavity and moves down the back (or posterior) of the mouth and throat. They are usually a sign of a more serious underlying medical condition, such as high blood pressure, hemophilia, other bleeding disorders, or a nasal tumor. Blood-thinning medications can also cause posterior nosebleeds.
