Are there any benefits to donating blood? Is type A blood good?

The benefits of donating blood to the body: Donating blood scientifically and rationally not only does not bring harm to the body, but on the contrary, it is also beneficial to health. For a person weighing 50 kg, he should have 4000 ml of blood, but the amount of blood participating in the effective circulation is only 80 of the total blood volume, i.e. 3200 ml, and the remaining 20 i.e. 800 ml is the reserve blood volume.

Through the above analysis, the phenomenon can be analyzed: that is, if a person cuts his finger or suffers a physical injury, 20 percent of the reserve blood immediately participates in effective circulation, but does not need to replenish blood in clinical practice. According to the provisions of the "Blood Donation Law", a person donates 200 ml or 400 ml of blood at a time, with an interval of 6 months, such a blood donation only uses a quarter or half of the body's reserve blood volume (800 ml), and is in line with the human red blood cell metabolism cycle, which is not harmful to health.

At the same time, human blood loss can continuously stimulate bone marrow hematopoiesis, so that blood can maintain a more vigorous metabolism, continuously produce more vigorous young blood cells, improve human immunity, and make people healthier and longer. In addition, according to the data, those who regularly donate blood scientifically and rationally have a significantly lower incidence of cardiovascular and cerebrovascular diseases and cancer than those who have not donated blood. Blood donation can also reduce blood lipids, dilute viscous blood, and alleviate the hidden blood of arteriosclerosis.

Blood donations can have a blood donation card, and when they reach a certain amount, they can have free blood when they have surgery. Different blood types have different characteristics, and there is no one blood type that is good or bad.

The dedication is particularly strong. The other is that you can't offend him or her, and you will hold a grudge for the rest of your life.

Generally speaking, Type A people are steady, quiet, affectionate, persistent, and focused. When you're at your most attractive, you're smiling. Generally speaking, people with blood type A are very good at suppressing their feelings. But once the relationship is bruised, recovery is quite difficult and takes a long time!

The virtues of people with blood type A are meekness, prudence, carefulness, humility, introspection, affection, compassion, sacrifice, harmony, melancholy, etc.

The disadvantages of blood type A people are worrying, emotional, weak-willed, indecisive, withdrawn, non-social, shy, pessimistic, shameful, and self-deceptive.

The first characteristic of AB blood group is rationalization. They pay less attention to social morality, human feelings, and various institutional issues, and prefer to be reasonable and regular. They have excellent analytical skills and a strong critical spirit, and behind this spirit is reality-based objectivity.

Therefore, most AB blood types have a distinct outlook on life and think that their own affairs are fully reasonable. When you really get close to and get along with AB blood type, you will always find that they are very gentle and easy to socialize with.

In addition, the AB blood type is intolerant of refusing sincere entrustment because of the embarrassment, so it gives people a cordial feeling. But as time goes on, their sense of distance from others becomes clearer and clearer, which is regrettable. The reason for this is that it is difficult for blood type AB to trust others, and at the same time, it is not believed that you will be absolutely trusted by others.

Although in general, AB blood group has more advantages than other blood types, but fewer people have achieved great success. This is probably due to the fact that AB often retreats or simply gives up at the last decisive moment, and tries to avoid taking risks. In the event of failure, AB usually passes on the cause of the failure to others, which is one of the disadvantages of AB (AB can accept A, B, AB, and O; Type AB can only donate blood to type AB. )

Blood type AB is the "universal blood recipient" and can only donate blood to blood type AB.
