Is it good to donate blood? As the title suggests, thank you

Well, 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 appropriate blood donation, especially single donation of red blood cells and platelets and other formed components, can significantly reduce blood viscosity, speed up blood flow, and increase 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.

There are good and bad Good good: Promotes blood circulation and helps others Bad: In case a blood collection device is not clean, it is you who are unlucky.

Of course, all the benefits are harmless, helping others and benefiting oneself.

Of course it's good, it's good for your health, no problem.

To summarize the disadvantages of blood donation that are hotly discussed on the Internet, it mainly focuses on the worry of contracting infectious diseases when donating blood, in fact, this is a completely unnecessary worry, because the needles and blood bags used in blood collection and supply institutions across the country are disposable medical consumables that have been strictly tested and qualified by the state, and there are strict operating procedures and requirements for blood collection.

1. You can enjoy free blood. Blood donors who have donated less than 800 milliliters of blood can use blood for clinical use within five years from the date of blood donation, and can use blood for free at three times the amount of blood donated; After five years from the date of blood donation, clinical blood can be used free of charge according to the amount of blood donated. Blood donors who donate more than 800 milliliters of blood can enjoy free clinical blood for life.

2. Good for physical health. Appropriate blood donation will reduce blood viscosity, reduce coronary heart disease, reduce the incidence of cancer, and improve self-hematopoietic function.

3. Save lives and save the lives of others.

No, I used to think that donating blood could help people in need, but now the hospitals are very dark, and the blood you donate is sold Even if you donate blood, I don't know if those syringes that have been sterilized are qualified, and it is very likely to be infected with AIDS.

Blood donation helps to regenerate and renew blood cells and improve body function, which has great benefits. However, there is also a health rule on the amount of blood to be donated: a minimum of 200 ml and a maximum of 400 ml per donation.

If you don't pay attention to donating blood, you may experience symptoms such as dizziness, but this can be avoided. In addition, if the needles used for blood donation are not sterilized thoroughly, there is a possibility of blood disease infection, but this is still relatively rare.

I think it's good, so some old blood cells are withdrawn, and aren't they new blood cells being made?

Well, regular blood donation boosts metabolism.

It is said to be bad. Your metabolism is the best.

Blood donation according to the standard is harmless to the body and has benefits

I think it's okay, I gave it once.

It's not good, you go to the space and see, there are people who are too dense.

Change blood frequently, so as not to make the blood too thick, and the blood is thick, and it is easy to have high blood lipids.

Are there any benefits to donating blood.

The biggest advantage of "blood donation" is that it can help patients, and it is also a manifestation of the benevolence of unpaid blood donors. At the same time, it can promote the metabolism of the human body, which is a kind of behavior that benefits others and self. In addition, according to the regulations of each region, blood donors and family members can also enjoy corresponding preferential policies for blood use.

Nowadays, unpaid blood donation is promoted in society. It is said that "moderate blood donation is good for health". Theoretically, this statement is possible.

1. Blood donation can improve hematopoietic function.

Because the body's hematopoiesis has a regenerative function. After losing blood, the red and white blood cells and platelets in the blood decrease, and donating blood prompts the production of blood cells.

2. Blood donation can reduce the viscosity of blood, make the blood flow naturally diluted, and reduce blood lipids.

3. It can reduce the occurrence of heart disease.

Blood donation is the outflow of blood from the human body. When the amount of iron in the blood is exceeded, the risk of heart disease increases. However, iron can be excreted through bleeding, and the blood flow from donated blood can reduce iron levels.

4. Appropriate blood donation is beneficial to longevity. 1. The donated blood cannot be used directly.

After the blood is received, it will go through rigorous testing, and then the plasma, red blood cells, white blood cells, platelets, etc. will be separated. Such blood components can be stored in different ways for ease of use. During the use process, you can choose which ingredient to infuse according to the condition to achieve the highest effect.

It can also reduce the occurrence of infectious diseases.

2. Although it is a free blood donation, it still costs money when using it.

This is because in the process of blood collection, separation of blood components and blood use in blood stations, there will be consumption of manpower and material resources, as well as the preservation of blood, which will lead to the cost of blood use. And when using blood, it can only be used by the donor's immediate family.

3. Although there are many people who donate blood for free. But there is still a "blood shortage" every year.

4. There will be no blood available when blood is used. Sometimes surgery is delayed because there is no blood.
