Trauma to the Nose
Aside from overdrying, another common reason for nosebleeds is trauma. Your nose contains many blood vessels and, because of its protrusion from the face, they can easily pop and result in bleeding. Popular winter sports, like skiing, snowboarding, ice skating, sledding and, of course, snowball fights, can all make you and your family more susceptible to accidents that could cause a nosebleed. For this reason, it's important to wear appropriate head gear and padding when participating in a contact sport, and properly treat nosebleeds as soon as they occur. Rather than tilt your head up, as many do to contain the mess, arch your head forward and use tissues to catch the blood. Squeeze your nostrils for several minutes to encourage clotting, and keep your head above your heart to slow the bleeding. Refrain from lying down or resting your head between your legs.
