The human blood is constantly metabolized all the time. Even if you don't donate blood, the blood cells in your body will age and die and become blood waste. Regular and moderate blood donation can enhance human immunity and disease resistance, stimulate bone marrow hematopoietic organs, promote human metabolism and prolong life. At the same time, regular and appropriate blood donation can alleviate hyperviscosity and reduce blood viscosity, which has certain positive significance for preventing cardiovascular and cerebrovascular diseases.
According to a scientific study in Finland, moderate blood donation has an unexpected effect on preventing heart disease in some healthy adults (especially male adults). Experts conducted an experimental investigation on more than 20,000 adults living in eastern Finland. The results show that compared with regular blood donors, the incidence of heart disease in those who have never donated blood is twice as high.
