Environmental factors such as low humidity, which is common during the winter, can induce mucosal irritation and bleeding. The incidence of nasal bleeding increases in colder weather. Infections of the nose and sinuses can cause a nose bleed. Allergies can also cause mucosal inflammation, which leads to nose bleeds. In some special cases, migraine headaches in children have also been proposed as a causative. Trauma to the face can also cause a nose bleed to occur. If you get a nose bleed, you should avoid certain situations and actions which may make it worse. Do not lean backwards. This may cause blood to run down your throat, which could induce vomiting. You should also avoid speaking and coughing. This can irritate the nasal mucosa and re-bleeding can occur.

Do not blow or pick the nose, especially if the bleeding is decreasing. You can dislodge formed blood clots and bleeding can reoccur. There are certain situations when you need to visit a doctor. If the bleeding is severe, more than a few drops, lasts more than 30 minutes, and reoccurs frequently, you should see a doctor. You also need to seek medical attention if you become extremely pale, fatigued, or disoriented. This can occur as a result of significant blood loss. If you have difficulty breathing, especially if blood passes down your throat, you need to see a doctor. This can lead to irritation and coughing. There is a chance of infection as a result, which can eventually cause breathing issues. You should always see a doctor if the nose bleed began as a result of severe injury to the nose. You should also see a doctor if you have a nose bleed while you are taking medicine that prevents blood clotting, such as warfarin, clopidogrel, or a daily aspirin.
