"The nasal cavity is the" front position "of the respiratory tract," said Mars, chief physician of the Department of Otolaryngology, the First Affiliated Hospital of Henan College of Traditional Chinese Medicine. There is a membrane in the nasal cavity, and blood vessels and glands are distributed on the mucosa. The weather is dry in spring, and under the influence of climate, the nasal mucosa will also become dry. In addition, some people, especially children, always pick their nostrils with their fingers, which can easily damage the nasal mucosa and cause nosebleeds.

Many people get cocky after a nosebleed. "In fact, this is not right." Li Ying said that raising your head would make blood flow to your throat. When the blood volume is too large and too urgent, it is easy to choke into the trachea and lungs, causing respiratory obstruction.

Mars reminded that when encountering nosebleeds, you should sit down first, relax yourself and lean forward slightly. Never lie on your back, nor lean back or bow your head. If there is blood in your mouth, you should try to spit it out. At this time, you can apply a cold towel to the back of your head or neck, and gently press your fingers on your nose for 3 to 5 minutes. The intensity of acupressure should be based on feeling slight pain and breathing with your mouth open. Roll up sterilized cotton or clean paper towels and stuff them into the bleeding nostrils. Be careful not to push too deep. /kloc-take it out gently after 0/0 minutes.

"If you find nosebleeds, don't be nervous, because when you are nervous and impatient, your blood pressure will rise, which will easily lead to excessive blood loss and complications." Mars said.

According to early education experts, nosebleeds often occur in spring. In the view of Chinese medicine, nosebleeds are mainly due to excessive heat and rising yang in spring, which makes people easily get angry. Coupled with the warmer climate in spring, windy weather reduces the air humidity, and the nasal blood vessels that contract for too long in winter begin to expand, leading to dryness and itching of the nose. If the amount of exercise increases at this time, the nasal mucosa capillaries will be strongly shaken, which is easy to rupture and bleed. Nosebleeds caused by infection, fever and hypertension also belong to this category. Treatment should be based on the principle of clearing heat and purging fire, cooling blood and stopping bleeding.
