1, making people healthier
For those who insist on long-term moderate blood donation, their bone marrow hematopoietic system will be constantly stimulated, the proportion of fresh blood cells will be significantly higher than that of non-donors, and blood donation will also reduce blood viscosity. Some scientific research at home and abroad shows that blood donation can not only make people more awake, but also make people healthier.
2. Reduce the incidence of coronary heart disease.
Blood donation can have a positive impact on the cardiovascular and cerebrovascular system, and then reduce the incidence of cardiovascular and cerebrovascular diseases.
3. Reduce the incidence of cancer.
Iron is one of the essential elements for human body, but it is found that if the iron content in human body exceeds 10% of the normal value, it will increase the risk of cancer, and blood donation can help the human body excrete too much iron. From this perspective, blood donation can reduce the incidence of cancer.
Second, shortcomings.
Proper blood donation is harmless to health. Donating 200 ml ~400 ml (5%~ 10% of the whole blood) at one time by healthy school-age blood donors will not affect their health. As long as you choose a regular blood donation station or hospital and follow the advice of staff or doctors, it will not endanger your health.
