5. Trauma To The Nose
Why It Happens: Any hard blow to the nose, besides being very painful, can cause the delicate blood vessels to rupture, leading to a bloody nose.
Additional Info: Hard blows to the head have also been known to cause nosebleeds, although the exact reason for this is not always clear.
What To Do: Sit down and lean forward to prevent the blood from running down your throat. If it’s not too painful, pinch the bottom of the nose closed with your thumb and forefinger for about ten minutes. Applying an icepack to the nose can also help and will reduce any swelling.
