Why is it easy to have nosebleeds in autumn and winter?

A nosebleed is a nosebleed, also called a nosebleed. The causes of epistaxis are various and complicated, which are often classified as local nasal cavity and total nasal cavity in medicine. Nosebleeds in autumn and winter are mostly caused by dry weather and climatic conditions.

So why do dry weather and palpitations cause nosebleeds?

1, to understand this problem, we must first understand the structural characteristics of the nose. The inner wall of human nasal cavity is afraid of a layer of moist nasal mucosa, and the capillaries on the surface of nasal cavity are very rich, especially in the vestibular area of nasal septum in front of nasal cavity. Capillary is not only rich, but also superficial and dense, which is often called "bleeding-prone area" in medicine. Because the nasal cavity is a breathing channel, it is particularly sensitive to meteorological requirements such as temperature, humidity and air pressure. When the air is dry, it often makes the nasal mucosa dry, scab and wrinkle. Because the nasal cavity is dry and itchy, the nose is often kneaded consciously or unconsciously, thus causing bleeding, or when the nasal mucosa is wrinkled, the capillaries will rupture and bleed.

2. The weather and climate in autumn and winter in all parts of China are generally dry, which is the meteorological reason for the dryness of nose 1 mucosa and the cracking of capillaries. Therefore, nosebleeds are more common in autumn and winter.

3, in the process of delivery, once found nosebleeds, don't panic, can take simple treatment measures, let the patient sit down, lie down, rest quietly, with a crucible cold wet towel paste nose root and forehead or the back of the head, if conditions permit, can also use ice packs cold compress, generally can stop bleeding. If it doesn't work, you can also use acupressure, that is, the patient holds his nose with his thumb and forefinger, leans his head forward, breathes with his mouth open, and presses 5 on both sides. 10 minutes can stop bleeding. In addition, a proper amount of garlic can be taken, peeled and mashed, and applied to the middle of the feet (Yongquan point).

4. Wrap it with gauze for external use and remove it after stopping bleeding. If bleeding persists, you should be sent to hospital immediately. If bleeding occurs frequently, you need to go to the hospital in time to find out the cause and treat it as soon as possible.
