Patients with nosebleeds who pat their foreheads with cool water will have some auxiliary therapeutic effect. After patting the forehead with cool water, the patient’s body temperature may drop, which will slow down the blood flow and slow down the patient’s nosebleeds. However, it is still necessary to actively treat the primary disease and clarify the specific situation in the patient’s nasal cavity. If there is a rupture of a blood vessel, electrocoagulation is often required to stop the bleeding completely. If there is a simple mucosal rupture, normal compression for about 5-10 minutes should result in significant improvement of the nasal bleeding. Patients can also use ice packs to apply cold compresses to the bilateral neck, which can also be helpful in the case of nosebleeds. Patients should pay attention to the protection of the nose, usually spray with physiological sea saline to play the role of moisturizing, avoid being hit by external forces, and do not use their hands to dig the nostrils often.
