4hw.org: blood donation is a kind of social public welfare activity. The State advocates free blood donation. Blood donation can not only provide fresh blood to the blood bank, but also provide blood for patients in need of blood in the hospital. It can also help to improve the ability of blood regeneration and disease resistance. Let's see what are the advantages and disadvantages of blood donation, and what are the precautions before and after blood donation?
1. It is good for blood production
Many people worry that blood donation is harmful to their physical and mental health. Blood donation is like anemia? In fact, it is not. Because the blood of human body is constantly metabolizing, there are many blood cells from aging to apoptosis at every moment, but at the same time, a large number of new cells are constantly produced, so as to better maintain the normal metabolism balance of human body. Moreover, when the human body's own hematopoiesis function is gradually enhanced after blood donation, it is conducive to the timely supplement of the lost blood cells.
Among them, bone marrow is an important hematopoietic organ in the human body, but with the continuous growth of people's age, the human body's own hematopoietic function and blood cells in the blood show a gradual downward trend. And the full blood can nourish the viscera and organs of the whole body effectively, which is conducive to the functional regulation of the five viscera and six Fu organs. Therefore, if the hematopoietic function of the human body decreases, it is easy to make the normal viscera and organs function damaged.
In the process of blood donation, it can have an excellent regulatory effect, because after blood donation, the number of blood cells in the blood gradually decreases, which will have a certain stimulating effect on the bone marrow, so that the blood cells stored in the bone marrow can be fully released, and also stimulate the hematopoietic tissue of the bone marrow, so that the blood cells in the blood can be effectively generated, which is also to enhance the human body's own production Important methods of blood function. Therefore, for a healthy person, if blood donation is carried out according to the specified items, it will not have adverse effects on people's body, nor will it cause adverse damage to 'vital energy', and it will also be conducive to the generation of blood in the body.
2. Prevention of cardiovascular and cerebrovascular diseases
Nowadays, many people can't live without big fish and big meat in almost every meal, and often eating high fat and high fat food is also an important factor to induce the increase of cholesterol in the blood. In addition, with less daily physical activity, the body will inevitably accumulate a lot of fat, if not relieved in time, it is easy to make the blood vessel wall be a layer of thick fat accumulation.
Thus, the blood viscosity symptoms will be produced, and the long-term development will reduce the elasticity of blood vessels, which is also the main form of inducing cardiovascular and cerebrovascular diseases. The normal circulation of Qi and blood is the main guarantee to maintain people's physical and mental health, and once the blood can't circulate normally, it is easy to induce diseases.
Regular blood donation can effectively reduce the composition of the blood, the largest proportion of which is iron and protein, which has a good dilution effect on the blood, promotes the flow rate of the blood, and naturally reduces the blood lipid, which also reduces the risk of arteriosclerosis. Therefore, to master the correct blood donation method is an excellent and effective way to prevent cardiovascular and cerebrovascular diseases.
Before blood donation, first of all, you can't get sick, especially infectious diseases. It's better for women not to donate blood in or near menstrual period. In addition, pregnant women, children, the elderly and people weighing less than 90 Jin can't participate in blood donation.

Before and after blood donation, drinking, smoking, injection, etc. are not allowed. Some bad habits should be corrected.
After blood donation, you'd better eat some blood tonic foods, such as red dates, milk, purple potatoes, walnuts, etc., to help your hematopoietic system recover as soon as possible, to prevent and avoid anemia, dizziness, tinnitus and other problems.
After donating blood, you can't take part in strenuous exercise, which will cause the dissolution of muscle transverse lines and endanger your life. It's better to take a walk or take a nap to supplement your physical strength.
