Since more colds occur in winter, more nosebleeds occur then. However, vigorous exercise in hot weather can also bring on nosebleeds in children without colds. Repeated nosebleeds in the same child are common. The child should be in a sitting position with the upper body tilted forward so the blood does not run back down the throat to be swallowed. For comfort, the forehead can rest against the wall.
Excess blood irritates the stomach and causes vomiting.
Some children have nosebleeds while asleep and the first the parent knows about it is when the child vomits blood on awakening. Sometimes as long as l5 minutes is necessary. If you can determine that the blood is coming from one side only, you only need pressure against that side. Using a cold pack on the back of the neck or bridge of the nose will do no harm, but be sure to continue pinching the nose shut at the same time. P.E. should be curtailed for the day.
