Blood donors are rewarded handsomely. Why are so many people unwilling to donate blood?

Because donating blood is risky, but there must be no risk if you don't donate blood.

1. Injury to blood vessels Everyone knows that blood donation is done through the vein of the arm, but few people know that this seemingly small trauma actually causes permanent and irreversible damage to blood vessels. It may not be a big problem under normal circumstances, but if your blood pressure is too high or you encounter special circumstances, that little eye of a needle may be the last straw to overwhelm the camel. Blood vessels may burst under great pressure, so some people are unwilling to take risks.

2. Risk of infection The previous medical equipment was not as strict as it is now, especially when blood can be exchanged for money. Many blood donation equipment has never been used once, nor has it been strictly disinfected. As a result, many people were infected by blood donation in those days. Even if the system is perfect now, they will still be infected because of improper operation by medical staff. Originally, it was the beauty of adults, but in the end it plunged them into the abyss, which many people did not want to meet.

3. The risk of weakness and weight gain after blood donation generally requires a light diet, good rest and good blood quality before blood donation. After donating blood, the medical staff will remind you to have a good rest and drink more water, because your blood's ability to transport oxygen is very poor at this time. If your system is good, you can have a good rest and recover slowly. But if you are in poor health, your body will secrete an acid, which will greatly increase the oxygen carrying capacity of your blood, but at the same time, this acid will do great harm to your brain. Some people who donate blood regularly will also say that donating blood will make people fat. Although we can't explain the truth of this matter from a scientific point of view, we would rather believe it. Especially for girls, any factor that may have something to do with gaining weight will be rejected by them without hesitation.

According to the author's own experience, the first day will probably be very sleepy, and then the weak period will last about a week. I will have a particularly good appetite for a while, but I don't know if it has an absolute relationship with blood donation. Everyone knows the importance of blood to the body. On the other hand, even if nutrition is supplemented in time, it takes time to change from nutrition to blood. After donating blood, there are still many taboos, such as not taking a bath, not swimming, not exercising vigorously for a short time, asking for a good rest and then eating lightly and not drinking. In this era when people prefer to think for themselves, few people are willing to do such thankless things.

Compared with the cost of blood transfusion, this reward is not so generous. It is true that blood preservation, transportation and testing all need to be charged, and it is understandable to charge appropriately. However, the annual salary of ordinary employees in blood stations is easily over 20W, which also makes many people feel chilling. Why did your contribution to society become wealth easily accumulated by others?
