Anonymous users2024-02-07Yes! The total blood volume of an adult is about 4000-5000 ml. The weight standard for blood donation is set at 50 kg for men and 45 kg for women.
A person donates 200-400 ml of blood at a time, accounting for only 5%-10% of the total blood volume, plus the blood drawn out is the blood of the peripheral blood vessels, the human body will automatically release the blood originally stored in the spleen, liver and other internal organs into the blood vessels, maintain a constant blood volume, and the water and inorganic substances lost after blood donation will be replenished in 1-2 hours; Plasma protein, which can be replenished within a day or two; Platelets, white blood cells, and red blood cells also return to their original levels. Therefore, blood donation will not affect the health of blood donors.
Therefore, healthy people donating blood according to the regulations will not have any effect on the body. After donating blood, the body's hematopoietic tissue will automatically accelerate hematopoiesis, and it can generally return to the original level after half a month. Appropriate nutrition is increased to provide sufficient raw materials for blood production, and the focus of supplementation is on protein, iron, vitamin B12, folic acid, etc., which are needed for hematopoiesis.
High levels of iron in the human blood can significantly increase the risk of heart disease, and donating blood in moderation can greatly reduce the amount of iron in the blood.
It will not hurt to donate blood in moderation, protect the puncture hole after donating blood, and properly supplement nutrition.

No, there are numerous scientific studies that prove the health benefits of donating blood. 1. It can prevent and alleviate hyperviscosity Scientists have used hemorheology and hemodynamics to study the relationship between blood and blood donation, and found that insisting on long-term blood donation, especially the single donation of red blood cells and platelets and other formed components, can significantly reduce blood viscosity, speed up blood flow, and improve cerebral blood flow, so as to alleviate or prevent hyperviscosity, and make people feel relaxed, clear-headed, and energetic. 2. It can prevent and reduce the occurrence of cardiovascular and cerebrovascular diseases An expert in Qingdao has conducted a controlled study on blood rheology on 127 multiple blood donors, 87 hypertension patients, and 60 ischemic stroke patients, and the results show that blood donors have a positive effect on reducing the occurrence of cardiovascular and cerebrovascular diseases; A Finnish research team surveyed 278 men aged 42 to 60 years and found that those who had donated blood had 86% fewer coronary heart disease after five years than those who had not. Another group of studies, 1532 people who donated blood for 2 times were followed up and observed, and the results showed that only one person had acute myocardial infarction, and the incidence rate was 226 of the 2306 people who did not donate blood in the same period, and the incidence rate was significantly higher than that of the blood donation group; A study by a Cardiovascular Disease Research Group in the United States also showed that the risk of cardiovascular disease in blood donors (men) was only 1 2 in non-donors over a 3-year period. >>>More
