2. Blood donation has a good long-term effect on cardiovascular and cerebrovascular systems, which can prevent and relieve blood viscosity and reduce the occurrence of cardiovascular and cerebrovascular diseases. Regular blood donation reduces a part of the sticky blood in the body, and then through normal drinking water, the blood volume is replenished and the blood is naturally diluted, so that the blood lipid will be reduced. Insisting on proper blood donation can reduce all components in blood, especially iron and protein, and also reduce blood viscosity and speed up blood flow. With the increase of oxygen supply, people feel relaxed and sober, which can effectively reduce arteriosclerosis, thrombosis, cerebrovascular accident and myocardial infarction.
3. Regular blood donation can improve hematopoietic function. After blood donation, due to the decrease in the number of blood cells, it stimulates the release of mature blood cells stored in bone marrow, stimulates hematopoietic tissue in bone marrow and promotes blood cell production. Regular blood donation within the prescribed time limit can keep the bone marrow vigorous.
4. It can promote and improve mental health. A large number of studies show that healthy emotions can communicate with the brain and other tissues and organs through the nervous system, body fluids and endocrine system, so that they are in a good state, which is conducive to the enhancement of human immunity and resistance. Blood donation is a noble character to save lives. While helping others and being kind to others, it also purifies one's spirit, soothes one's soul and enriches one's work and life. Doing good by virtue actually helps others and yourself, which is an important element of health and longevity.
