NOSEBLEED
Nosebleed is the exit of blood through nose both because of intentionally or unintentionally. The cause of nosebleed can be the small blood vessel inside the hole of nose full of blood. This blood vessel shrivels and swells as a reaction of the various stimulation, such as the cold, hot, dry and damp air, or because of the over exercise, such as running or climbing mountain. Therefore, the people, who do not do many activities, are also rare for having nosebleed.
The blood vessel in the intranasal septum is part of the very sensitive little area and it is a source of the nosebleed disease. To overcome it is; firstly, squeeze the nose with the index and thumb fingers. This is because the squeeze will stop the blood stream and close the blood vessel. The easiest way is by using the chemical, which can burn and plug up the blood vessel. The doctor can do it.
This is not true that the best way to stop nosebleed is by tilting the head up to backside. This precisely makes the blood stream to the backside of nose and enters to throat. The better is if the patients sit by bowing the head in order that the blood drops to downward.
The infection like cold can cause nosebleed. Scraping the nose with the fingers nail can also cause the bleeding injury. The disturbance attacking all the body, such as the hardening of blood vessel and hypertension, can also cause nosebleed. The increase of the striking blood pressing can make the blood vessel in the hole of nose open. Yet, the exit of blood precisely can decrease the pressing preventing the happening of bleeding in the more dangerous area, like brain.
The disturbance in blood such as the mechanism of blood clotting, which is less effective, can also cause nosebleed. The other cause of nose bleeding is because of the too big mental effort, so that it increases the pressure of blood and skull. Nosebleed often happened to the students facing the examination, the musician performing a concert or the people undergoing the psychological stress.
Whatever causes are, the best way to overcome it is by squeezing the nose in order to stop the bleeding and find some helps from a doctor.
