Nosebleeds in summer? Common causes of nosebleeds in hot weather

Is the frequency of nosebleeds increasing in hot weather? In hot weather, many people feel that the nasal cavity is dry, and then inexplicably symptoms of nosebleeds appear. Why is it particularly easy to have nosebleeds in hot weather? Here are some possible causes of nosebleeds. 1. The nasal cavity is too dry: the nose will bleed in summer, which is related to the hot weather and the dryness of the nasal cavity. When the nasal cavity becomes too dry, the tiny blood vessels inside it can rupture, causing bleeding. 2. Allergic rhinitis: When the nasal mucosa becomes inflamed and swollen, it will become more fragile. At this time, frequent entry and exit of the air-conditioned room, alternating hot and cold will cause nasal itching. Unbearable rubbing with hands may cause minor damage to the surface. It can rupture the capillaries and cause nosebleeds. 3. Stimulated expansion of blood vessels: Exposure to the sun can cause the blood vessels in the head to dilate and cause nosebleeds. In addition, drinking alcohol and eating too much spicy food may also cause nosebleeds. Fourth, high blood pressure, arteriosclerosis: patients with hypertension or arteriosclerosis, blood vessels will become fragile, easy to bleed. In this case, frequent nosebleeds or high blood pressure may cause heavy bleeding, so be careful.
