There are many benefits for men to donate blood

The total blood volume of an adult male is 4000~5500 ml. Normally, 80% of the blood circulates in the heart and blood vessels, and the other 20% is stored in organs such as the liver and spleen. Donating 200~400 ml of blood at a time will not cause a decrease in circulating blood volume, nor affect normal physiological activities.

There are at least three major benefits for healthy men to donate blood according to regulations.

First, it can prevent and reduce the occurrence of cardiovascular and cerebrovascular diseases.

Research by cardiovascular disease experts in the United States and other countries shows that the risk of cardiovascular disease for male blood donors is only half of that for non-donors. For men with reduced physical activity, more body fat or high blood lipids, regular blood donation can reduce blood viscosity and eliminate the hidden dangers of arteriosclerosis.

Second, it helps to prolong life.

Donate blood regularly and in moderation to stimulate the bone marrow, maintain vigorous hematopoietic function, promote metabolism, and enhance immunity;

Third, it can reduce the incidence of cancer.

The iron content in men's bodies is generally high, and when the iron content in the body exceeds 10% of the normal value, the risk of cancer increases. Therefore, men can discharge excess iron by donating blood in moderation, thereby reducing the risk of cancer.
