In many large cities, in addition to going to the hospital to donate blood on their own, there are also a lot of mobile blood donation vehicles on the streets, which can not only make people feel that donating blood is a relatively easy thing, but also can enhance people's enthusiasm for donating blood to a certain extent, but even so, there are still many people who are unwilling to donate blood in life, because in the cognition of these people, blood donation is actually a thing that will harm the body, and people who donate blood for free, There is also a charge when there is a need for blood, and this kind of "transaction" is really not very cost-effective. So, does donating blood really hurt the body?
Normally, in order to ensure the safety of the blood donation process, the medical staff will strictly follow the relevant needs, the medical equipment used is disinfected, which actually strictly eliminates the emergence of infectious diseases, and before donating blood, the medical staff will also strictly conduct the corresponding physical examination of the blood donor, if the blood donor is found to not meet the blood donation requirements, then the blood donor will not be allowed to donate blood rashly.
For healthy adults, the amount of blood in their bodies is about 4,000 ml to 5,000 ml, of which blood accounts for about 3,500 to 4,000 ml, and the remaining 500 to 1,000 ml of blood is mainly stored in the liver, spleen and other organs. According to the relevant requirements, the amount of blood donated by blood donors at a time cannot exceed 5% of the total number of human bodies, so after donating blood, it will not have a great impact on their health.
However, some people will experience rapid heartbeat and blood pressure levels after donating blood, which is mainly caused by the low quality of medical staff or improper methods in the operation process.
So, why is it that blood donation is unpaid, but there is a charge for blood use? I think the vast majority of people are very concerned about this issue, but what I want to tell you here is that the blood in everyone's body is not a commodity, so it is impossible to sell it at a price. Moreover, medical staff often incur some costs in the process of blood collection, and hospitals also need to have certain cost support when they preserve blood, so from this point of view, patients need to bear part of the costs when using blood.
Nowadays, the composition structure of clinical blood costs is mainly divided into three parts, namely the preparation of blood in blood stations, the cost of blood distribution and the cost of storing blood, and the relevant cost regulations are all from relevant regulations, and the hospital only charges part of the cost. Although this statement is not accepted by most people, it is still difficult to change the status quo.
And it is precisely because of this that blood donation will follow the principle of voluntary, for those who want to donate blood, what is donated is not only blood, but also a love, a force that may save the lives of others, and for those who do not want to donate blood actively, the state will not take compulsory measures.
In general, from a clinical point of view, blood donation will not cause certain harm to one's own health, but will enhance the body's hematopoietic function to a certain extent, accelerate the production of blood cells, and promote blood metabolism.
In addition, after donating blood, the blood viscosity in the human body will be reduced, and the blood circulation speed will also become faster, in this case, the ability of blood supply and nutrition delivery will be improved, which has a certain positive effect on the prevention of cardiovascular and cerebrovascular diseases and the reduction of the incidence of cancer.
Of course, in the aspect of blood donation, in addition to paying attention to the principle of free and voluntary, but also need to combine the actual physical condition of the blood donor to decide whether it is suitable for blood donation, if there are people who are willing to donate blood, their bodies suffer from certain diseases, or their bodies are too weak to meet the current blood donation requirements, then they will often not be accepted by the blood donation department, so as not to cause damage to the health of blood donors.
