Staying up late working or playing games usually causes the patient’s body to become inflamed, and the nasal mucosa becomes dry because it is not replenished with sufficient water, and the capillaries in the nasal cavity will rupture, thus causing the patient to have a nosebleed. When a nosebleed occurs, the patient should not be nervous, lean your body forward slightly and lower your head slightly, so that the nosebleed can flow naturally from the nostrils, then pinch the sides of the nose with your index finger and thumb for ten minutes, in most cases the nosebleed can be stopped. Of course, you can also use ice packs or cold water-soaked towels on the forehead and nose root for cold compresses to reduce the temperature of the head and nose, so that the capillaries in the nasal cavity contract, which can achieve the effect of reducing nose bleeding. If the patient has frequent nosebleeds or nosebleeds first-class is difficult to stop, must promptly go to the hospital to identify the cause and take targeted measures for treatment.
