As we all know, the dry climate in autumn makes it easy to cause the lack of fluid in the human body, making the skin and respiratory mucosa dry and cracked. Since the nose is the gateway to the upper respiratory tract, it becomes the first victim part. The nasal mucous membrane in dry conditions will reduce its own cleaning function, it is easy to dry scabs, dry scabs often cause damage to the mucous membrane and bleeding when they fall off. Especially in children, dry and itchy nose is the most common factor to develop the bad habit of nose picking. Repeated nose-picking over a long period of time results in ruptured blood vessels in the anterior part of the nasal cavity (especially below the anterior nasal septum). Understanding the reasoning behind this, it is easy to understand why doctors often use drugs such as compound camphor mint oil, paraffin oil, cod liver oil and other moistening medications for the nasal cavity when treating such diseases. But why do some people have good results with them and others do not? The reasons for this result are many. One is that the oil drops are too little and do not have the proper moistening effect; the second is that the condition is more serious and the dilated blood vessels are exposed, so the effect of oil drops alone is very limited, and the dilated blood vessels need to be treated locally to make them occluded and stop bleeding. If bleeding occurs at home, most of the bleeding can be stopped by using the index finger or middle finger to compress the nose, otherwise the positive way is to go to the hospital to find a specialist for treatment. For autumn dryness, besides emphasizing drinking more boiled water and light tea, some fruits and foods that nourish Yin and moisten the lungs and have a clear tonic effect, such as raw pear, radish, sesame, red dates, etc. are also very beneficial to eat regularly!
