You should not go to bed immediately after stopping a nosebleed, as there is a possibility of another nosebleed in the short term.
Nosebleeds are mainly caused by rupture of nasal cavity, sinus mucosa and blood vessels. In the nosebleed, the human coagulation mechanism plays a role in mobilizing a variety of coagulation factors and pro-coagulant substances, to guide the platelets in the bleeding part of the aggregation, adhesion, to play the effect of temporary hemostasis.
At this time, if immediately fall asleep, when the body lying down, due to positional changes so that the head parallel to the heart level, resulting in relatively high blood pressure in the nose. Higher blood pressure exists in the impact of ruptured blood vessel wall, triggering the coagulation plaque local collapse, or even partially off, and cause bleeding again.
Just stop nosebleed patients, can be in the forehead, bleeding side of the neck and nose, with cold compresses to promote vasoconstriction, to reduce the speed of blood flow and the temperature of the affected area of the therapeutic effect, is conducive to local hemostasis. Most can be about 1~2 hours after stopping bleeding, coagulation plaque stabilization closed blood vessels and then sleep, relatively safe. If bleeding again should actively seek medical treatment, follow the doctor’s instructions standardized treatment.
