The pros and cons of donating blood

In daily life, we often see slogans encouraging people to donate blood for free. Many people have also heard that donating blood is harmless to the body and is very beneficial to maintaining good health. So what is going on? What are the benefits of donating blood in moderation? What are the disadvantages?

Benefits of Donating Blood

1. Thin the blood

Diluting the blood and reducing its viscosity is one of the important benefits of donating blood in moderation. When the blood viscosity is too high during the lunar calendar, it is easy to cause thrombosis and induce cardiovascular and cerebrovascular diseases. Donating blood in moderation can dilute the blood, reduce its viscosity, and reduce the occurrence of these diseases.

2. Prevent cancer

Donating blood moderately on a regular basis can prevent cancer and reduce the incidence of cancer, because the blood contains a large amount of trace element iron. If the iron content in the body is too high, it is easy to make cancer high. After people donate blood moderately, the content of trace element iron in their bodies will drop significantly. At this time, cancer will stay away from them, and the chance of their body tissue cells becoming cancerous will be significantly reduced.

3. Prolong life

For people who have entered middle age, donating blood in moderation can also prolong their lifespan, because most of them have successful careers and good financial conditions, and their usual dietary level is relatively high. This makes their bodies prone to overnutrition, fat accumulation, and a significantly increased blood viscosity. In this case, diseases such as arteriosclerosis, coronary heart disease, and cerebral thrombosis will be prevalent. If they can insist on donating blood regularly and moderately, it can dilute the blood, prevent cardiovascular diseases, and significantly improve their physical health level, which can not only prolong their lifespan but also prolong their lifespan.

Disadvantages of donating blood

Normally, moderate blood donation does not have any obvious harm to the body, but excessive blood donation will endanger human health and cause people to suffer from a variety of adverse symptoms such as insufficient qi and blood, physical weakness, decreased immunity, and in severe cases, it can even lead to anemia.
