Nasal boogers with blood in the nose every morning may be caused by environmental dryness, deviated nasal septum and nasal inflammation. 1. Dry environment: when the indoor air is too dry at night, the humidity of the air inhaled into the nasal cavity is too low, which increases the brittleness of the mucous membrane of the nasal cavity and leads to rupture of the nasal cavity and bleeding. Due to individual differences, some people’s mucous membrane healing ability is poor, and the symptom of bloody boogers in the nose every morning occurs. 2. Deviated septum: The mucous membrane on the side of deviated septum is thin, and it will erode and bleed when blowing the nose repeatedly, resulting in the symptom of bloody boogers in the nose every morning. 3. Nasal inflammation: when suffering from dry rhinitis or atrophic rhinitis, the mucous membrane of the nasal cavity will be dry, and the capillaries will be brittle and easy to bleed and crust, resulting in the symptom of bloody boogers in the nose. When the patient appears every morning with boogers in the nose with blood symptoms can not be relieved, and accompanied by other symptoms, it is recommended that the patient go to the hospital in time for examination and diagnosis, and under the guidance of the doctor for treatment.
