" Most people think that you should tilt your head back to stop a nosebleed, but that conventional wisdom is wrong, says Yosef P. Krespi, MD, a WD advisor and professor of clinical otolaryngology at Columbia University College of Physicians and Surgeons.   Leaning your head back makes you more likely to swallow blood, which can lead to nausea and stomach irritation. Instead, keep your head level, and pinch your nostrils at the tip of your nose with your index finger and thumb for 3 to 5 minutes to stop the flow. If that doesn&amp;#039;t work, gently push a cotton ball or swab into the nasal passage to seal the area. (Go to the ER if a bleed lasts more than 10 minutes.) Prevent future nosebleeds by using a humidifier, staying hydrated and lubricating your nose with a petroleum jelly product (like Vaseline). "^^<http://www.w3.org/2001/XMLSchema#string>
