Having a blood y nose can make some people nervous, but in most cases, nosebleeds(流鼻血) are easy to stop and not so serious. Around three out of five people will have a bloodynose in their lifetime. Nosebleeds mostly happen among children from 2 to 10 years old and among adults aged 50 to 80.
◆What causes a bloody nose?
Most nosebleeds are caused by picking the nose and dry air. Blowing your nose too often when you have a cold can also lead to nosebleeds. All of these break the tiny vessels(血管) inside the nose, causing them to bleed. Causes of more serious nosebleeds include a head injury, a genetic disease, or, in some cases, a tumor.
◆How to stop a bloody nose right away?
You may know how to stop a blood y nose right away, but it's important to do it properly and safely.
Always sit up straight when your nose is bleeding, and never lie on your back. One of the biggest mistakes in first aid is that you should lean(倾斜) back with a bloody nose, but the best thing to do is leaning forward. The blood needs to go somewhere, and if the person leans back or lies down, it will most likely go down his throat, possibly causing choking(窒息). And try not to put something into your nose.
Pinching(捏住) the nose properly stops or slows the bleeding. Hold the nose for at least five minutes. Do not let go to check for bleeding until at least the first five minutes are up. If you can, keep pinching for longer.
After five minutes, see if the bleeding has stopped. If not, pinch again, but keep it up for 10 minutes this time. Remember: Don't let go to check for bleeding until the 10 minutes are up. If bleeding doesn't stop after that time, pinch it for another 10 minutes if necessary.
Remember that if you can't stop the nosebleed with these ways, see a doctor immediately.
◆What not to do after a bloody nose?
After a light nosebleed, do not lie down until 20 minutes later, but at least 30minutes or even an hour later after a bad nosebleed. Don't lift heavy things or pick your nose for a day. You should not blow your nose for at least two days.
