The weather is dry and windy.

The possible causes of nosebleed are rhinitis, nasal diseases (nasal septum deviation, nasal septum mucosal erosion, etc. ), high fever, hypertension, hemorrhagic diseases, vitamin loss. The common reason is that the dry weather leads to lack of water, dryness and bleeding in the nasal cavity. In this case, cotton balls can be dipped in water to keep the nasal cavity moist. In severe cases, apply erythromycin ointment, eat less greasy food and eat more fruits. Don't be nervous when bleeding. Under normal circumstances, nosebleeds are not life-threatening. It can compress the nasal alar of the bleeding side and put pressure on the nasal septum. Then go to see a doctor nearby. Chinese medicine believes that nosebleeds are caused by the upwelling of qi and blood. The nose belongs to the lung orifices, and there is a disease in the nose. Generally speaking, it has a lot to do with the abnormality of lung and liver. When people's qi and blood rise, especially when the lung is hot, people will have nosebleeds. When the lung qi is overheated, people's eyes will also be bloody or bleeding. The cause of excessive internal heat and nosebleeds is the same, both of which are the result of rising qi and blood, but excessive internal heat is not the cause of nosebleeds. If the nasal cavity is too dry, the capillaries inside will rupture, leading to bleeding. 90% of nosebleeds in clinic belong to vascular bleeding caused by vascular rupture. In this regard, patients need not be too nervous. In most cases, they can handle it themselves and stop the bleeding in time. When the nose bleeds, you can block the nose with a cotton swab and tilt your head back to stop the bleeding as soon as possible. At the same time, you can also apply a cold towel to your forehead or nose to reduce the temperature of your head and nose to relieve bleeding symptoms. If there is too much bleeding in the nasal cavity and it is difficult to stop, you should see a doctor in time. Young people with nosebleeds are also related to fatigue and exercise. Young people, in particular, love sports, and often when exercising, their noses suddenly start to bleed. Under normal circumstances, these bleeding symptoms can be stopped by the patient. However, without warning, it is best for people with sudden nosebleeds to go to the hospital for examination and rule out diseases such as nasal cavity tumors as soon as possible. Generally speaking, nasal vascular rupture bleeding does not need special treatment. Professor Yang Li said that because nosebleeds are related to lung heat, people should try to avoid the occurrence of lung heat in their diet and life. Drink less, eat less spicy food and eat less food that may cause fever. On the contrary, you can eat more bitter gourd, mung bean soup, watermelon, cold drinks and other foods. Take 3 grams of winter mulberry leaves, add cogongrass rhizome and Ophiopogon japonicus, and add appropriate amount of licorice to soak in water for drinking, which can achieve the purpose of clearing heat and reducing fire. Nosebleeds, medically known as "epistaxis", are mostly caused by "lung dryness and blood heat", and the capillaries are broken due to insufficient toughness. If not treated in time, it will cause serious consequences, such as atrophy of nasal mucosa, anemia, memory loss, decreased vision, decreased immunity, and even lead to ischemic shock, which is life-threatening. Children are active and often hurt their noses unintentionally, resulting in nosebleeds. In addition, they may put foreign objects into their nostrils out of curiosity, which may damage their nasal mucosa. The above situation may happen at any time, and the amount of blood flowing out is very small, so don't worry too much. As for why nosebleeds are particularly serious in winter, mainly because the weather is cold, we like to eat some hot food. When eating, the hot air will make the blood in the nasal cavity run faster. If the nasal mucosa is naturally thin or injured, it is easy to have nosebleeds. In addition, in the cold and dry environment, we need more blood to flow through the nasal cavity to increase the temperature and humidity, so the microfilaments in the nasal mucosa are prone to congestion, leading to nosebleeds. From the perspective of traditional Chinese medicine, the causes of nosebleeds can be divided into two categories: heat and weakness. If you often have nosebleeds, you also suffer from nasal sensitivity, yellow or green runny nose, or your lips are often red and smelly. It is very hot and dry. First of all, of course, we must clear away heat. More importantly, don't let him eat too much delicious food on weekdays. Snacks such as chocolate, cookies and French fries are also very hot and dry. Try to eat as little as possible. Treatment of adult nosebleeds: 1.
