Many things can bring on a nosebleed like a change in altitude, excessive nose blowing, or a bang or punch to the nose. Dry weather or certain medications can dry out the membranes inside the nose, also causing them to bleed. Nosebleeds rarely signal more serious illnesses and can almost always be handled with self-care.
Get into a sitting position. Do not tilt your head back or lie down. Pinch affected nostril(s) shut by pressing just above the flares and just under the nasal cartilage on either side for 20 minutes (timed with a watch or clock) while you breathe out through your mouth.
To prevent nasal linings from drying out, use a humidifier or vaporizer to add moisture to the air in your home. Place a small amount of petroleum jelly along the middle of each nostril one to three times daily to help moisten the membranes.
If repeated nose blowing or sneezing is causing nosebleeds, try to blow more gently and take an antihistamine to reduce sneezing. Avoid scented tissues which can irritate your nose, causing more sniffling and sneezing.
If you have recently moved to a high altitude location, be patient. The body takes several weeks to adjust to the change in altitude and the nosebleeds will eventually subside.
