The pros and cons of men donating blood

For men, moderate blood donation can help improve hematopoietic function, reduce the incidence of tumors, and is beneficial to the health of the body. Experts told us that if middle-aged men donate about 550 ml of blood each year, the chance of sudden heart disease will be greatly reduced and it will help improve heart function. Of course, we should also be careful during the normal blood donation process and not donate blood too frequently.

Benefits of donating blood for men

1. Men donating blood can reduce the incidence of cancer. Iron is one of the indispensable elements for the human body. Generally speaking, low iron levels in the body can lead to iron deficiency anemia and slow movements, but studies have shown that high iron levels can have the opposite effect. "International Cancer" once reported that if the iron content in the body exceeds the normal value by 10%, the risk of cancer will increase. Donating blood in moderation can effectively prevent cancer. As for women, they often lose a lot of iron due to bleeding during menstruation. Therefore, the study found no special relationship between iron content and women's risk of cancer. So, how can men eliminate excess iron in their bodies to reduce the risk of cancer? Experts believe that the main way is by flushing excess iron out of the bloodstream. Therefore, men with high iron levels in their bodies are encouraged to donate blood regularly, which is beneficial to both themselves and others.

Disadvantages of men donating blood

Donating blood can cause the weakening or even loss of the above blood functions. Simply put: the decrease in red blood cells will cause various organs in the body to not get enough oxygen, and the various life functions of the cells cannot be performed. The dizziness after donating blood is because the brain does not get enough oxygen supply, which is the same as the phenomenon of carbon monoxide poisoning. The decrease in white blood cells will reduce the body's ability to resist viruses, making it more susceptible to illness. This is the reason why the body becomes weak after donating blood. The decrease in immunity gives viruses such as colds, which are originally insignificant, an opportunity to take advantage. The lack of platelets will make it difficult for wounds to heal and cause bleeding to continue. Of course, no one is unlucky enough to get injured after donating blood. In the standardized process, all instruments used in blood donation are disposable consumables that have been strictly sterilized, and all disposable equipment used in blood collection must be discarded after use. Moreover, during the blood donation process, blood flows from the body to the outside of the body, and it is very difficult for pathogens outside the body to flow upstream and invade the human body. During the component blood donation process, the donor's blood is also circulated and separated in a strictly sterilized disposable fully enclosed pipe set. Not a drop of blood comes into contact with the machine. The machine is only a tool to produce centrifugation and will never cause cross infection.
