Does donating blood affect the body, and does donating blood affect the body

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.

3. Blood donation in men can reduce the incidence of cancer Low levels of iron in the body are prone to iron deficiency anemia and slow movement, and too high is counterproductive. Cancer International has reported that if the iron content in the body exceeds 10% of the normal value, the risk of cancer increases, and a moderate amount of blood donation can prevent cancer. The article also mentions that women lose a certain amount of iron due to blood loss during the menstrual cycle, so no significant relationship between iron content and cancer development in women has been found.

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 nervous, humoral and endocrine systems, so that they are in a good state, which is beneficial to the enhancement of human immunity and resistance. Blood donation is a noble act to save people's lives, while helping others and being kind to others, it also purifies their spirits, comforts their souls, and makes their work and life more fulfilling. Those who do good deeds do good deeds, and actually help themselves while helping others, which is an important element of health and longevity.

5. Prolonging life Some foreign scholars have also conducted prospective controlled studies on 332 people over 66 years old (blood donors) and 399 people of the same age and gender (non-blood donors), and the results show that the average life expectancy of the blood donation group is higher than that of the non-blood donation group; The survival rate was 67% in the donor group, which was higher than 40% in the non-donor group; The mortality rate in the blood donation group was 33%, which was lower than the 60% in the non-blood donation group.

No, it won't. Blood is mainly composed of plasma, blood cells and platelets, blood cells are like small life, all the time in the metabolism, so that the total amount of blood in the body is kept constant.

No, I've donated 4 times, no problem, and donating blood helps regenerate hematopoietic cells·· It has certain benefits for the body...

A: Appropriate blood donation will not affect your health, which is scientifically based. First, donating 200 ml of blood at a time only accounts for about 1 20 of the blood volume of the whole body, so it does not affect physical health.

Second, when the human body loses blood or donates blood, the blood in the "blood bank" of the liver and spleen is quickly released to increase blood volume and replace the lost. Thirdly, the blood has a strong metabolic capacity and can return to normal for a few days after donation.

No, if you donate the old blood in your body, your body will make new blood, which is beneficial to the human body.

Yes, proper blood donation is still good for the body, pay attention to the body!

It won't be good for the body and help with metabolism.

It will not be moderately bloody, but it will not be bad for the body.

In general, no.

No, just rest.

Normal blood donation is very beneficial to the body, which can better promote the blood circulation of the human body!

No. The total blood volume of a healthy person is about 8 of body weight, and the total blood volume of an adult is about 4000 5000 ml. 80% of the blood circulates in the heart and blood vessels to maintain normal physiological functions; The other 20 percent of the blood is stored in organs such as the liver and spleen, and in the event of blood loss or strenuous exercise, this blood enters the circulatory system.

A person who donates 200 400 ml of blood at a time only accounts for 5 10 of the total blood volume, and the stored blood will be replenished immediately after donation, and the circulating blood volume will not be reduced. The water and inorganics lost after donating blood will be replenished in 1 2 hours; Plasma proteins, which are synthesized by the liver and can be replenished within a day or two; Platelets, white blood cells, and red blood cells also quickly return to their original levels. The blood of the human body is constantly metabolized, and many blood cells are aging and dying all the time, and a large number of new cells are produced at the same time to maintain the balance of the body's metabolism.

After donating blood, the lost blood cells are quickly replenished due to the enhanced hematopoietic function. Therefore, a healthy person who donates blood according to the regulations will not have any impact on the body, let alone "hurt the vitality", but will be beneficial to health.

It doesn't matter if you don't donate blood regularly I've donated a lot of it before, and there's no problem.

No, on the contrary, donating the right amount of blood can allow the body to make new blood, promote hematopoietic function, and save yourself or others when you are sick It is very safe to donate blood to regular hospitals and blood stations.

Normal blood donation has no effect on the body.

Healthy people are not affected.
