What should thin people pay attention to before donating blood? Will I feel dizzy? What are the benefits? Did anyone donate blood today?

1. Blood donation has good long-term effects on the cardiovascular and cerebrovascular systems

Due to the improvement of living standards and the reduction of physical activity, people have accumulated more and more fat in their bodies. And it remains at a high level for a long time, commonly known as "thick blood". The result of "thick blood" is that fat adheres to the blood vessel walls layer by layer, eventually forming arteriosclerosis and reducing blood vessel elasticity, leading to cardiovascular and cerebrovascular diseases. Regular blood donation reduces some of the viscous blood in the body, and then through normal drinking water, the blood volume is filled, so that the blood is naturally diluted, and the blood lipids will decrease accordingly.

Persisting in an appropriate amount of blood donation can reduce all the components in the blood, with the largest reduction being blood iron and protein. It can also reduce the viscosity of the blood and speed up the blood flow. As the oxygen supply increases, people feel relaxed and clear-headed. It can effectively reduce arteriosclerosis, thrombosis, cerebrovascular accidents, myocardial infarction and other diseases.

2. It can prevent and relieve hyperviscosity

Scientists used hemorrheology and hemodynamics to study the relationship between blood and blood donation, and found that consistent long-term and appropriate blood donation , especially formed components such as red blood cells and platelets, can significantly reduce blood viscosity, speed up blood flow, and increase cerebral blood flow, thereby alleviating or preventing hyperviscosity and making people feel relaxed, clear-headed, and Full of energy.

3. Men donating blood can reduce the incidence of cancer

If the iron content in the body is too low, it is easy to suffer from iron deficiency anemia and slow movement. If the iron content is too high, it will be counterproductive. If the iron content in the human body exceeds 10% of the normal value, the chance of suffering from cancer increases. Appropriate blood donation can prevent cancer. The article also mentioned that women lose a certain amount of iron due to blood loss during the menstrual cycle, so there is no obvious relationship between women's iron content and the occurrence of cancer.

4. It can promote and improve mental health

A large number of studies have shown that healthy emotions can communicate with the brain and other tissues and organs through the nerves, body fluids, and endocrine systems, keeping them in a good state. state, which is beneficial to the enhancement of human immunity and resistance. Donating blood is a noble act of saving a life. While helping others and being kind to others, it also purifies your spirit, comforts your soul, and makes your work and life more fulfilling. Those who do good deeds are actually helping others while also helping themselves, which is an important factor in health and longevity.

5. Regular blood donation can improve hematopoietic function

Because since the birth of the fetus, bone marrow has become the main hematopoietic organ. As age increases, hematopoietic function and blood cell production rate gradually decline. After donating blood, due to the reduction in the number of blood cells, it has a stimulating effect on the bone marrow, prompting the release of mature blood cells stored in the bone marrow, and stimulating the bone marrow hematopoietic tissue, promoting the production of blood cells. Donating blood regularly and within the prescribed period can keep the bone marrow vigorous.
