Nosebleed Plan: Lean, Pinch, Wait
A nosebleed can look scary, but it is usually not serious. The inside of your nose is lined with many tiny blood vessels that sit very close to the surface. Dry air, a cold, or picking at your nose can make one of them break and bleed. Knowing what to do helps you stay calm.
Here is the plan. First, sit down and lean your body a little forward. Do not tip your head back. Tipping back lets blood run down your throat, which can upset your stomach. Second, use your thumb and finger to pinch the soft part of your nose, just below the hard bone. Third, breathe through your mouth and keep pinching for about ten minutes. Try not to peek early, because letting go too soon can start the bleeding again. A clock will help you count the time.
Tell a grown-up right away. If the bleeding does not stop after a second try, or if it began after a hard bump to the head, a grown-up should call a doctor.
To prevent nosebleeds, keep your fingers out of your nose and blow it gently. Those two habits help the most.
