Why does raising your chin when nosebleeds not only stop bleeding, but also kill you?

I believe everyone has had the experience of nosebleeds. Whenever a nosebleed begins, I always hear the old man at home say: Come on, lift your chin so that the nosebleed will stop soon? . But is this really the case? No, our nosebleeds are usually caused by excessive internal heat. Don't be afraid when we have nosebleeds. Please prepare clean gauze and put it in our nasal cavity, which will temporarily stop the bleeding.

1. Don't panic when nosebleeds, but be calm: because of human physiological structure, we can't look up when nosebleeds, because our nasal cavity is very close to the brain. Once we suddenly look up when we have a nosebleed, the dirty blood that should have been discharged will flow back to our nasal cavity. So what are the disadvantages of doing so? The downside is that the dirty blood may get stuck in our brains and cause people to suffocate.

Second, the correct way to solve nosebleeds is to gently wipe around the nostrils with clean gauze dipped in water, then put the prepared clean gauze on the nostrils in time, and then sit still for a while. Don't make big moves during this time, and then wait for the nosebleed to come out. At the same time, pay more attention to changing gauze, and the bleeding stopped after a few minutes.

Third, usually pay more attention to living habits and slowly learn to decompress yourself: people are under great pressure now. They not only have to work, but also study, which leads to all kinds of small problems in their bodies. Especially the most common fire, which is actually easy to solve. That is, eating more vegetables and fruits can not only bring a lot of nutrition to our bodies, but also keep us healthy.

Generally speaking, sometimes the remedies we think of to stop bleeding are unreliable, and you may die if you don't pay attention. So we should believe in science.
