Original title: Do you know the 6 major misunderstandings of AIDS infection with AIDS and affecting sperm vitality?

In the hot summer, many people have weakness, tiredness, and loss of appetite. Some people who are willing to donate blood free of charge are "discouraged" and worried that blood donation will hurt the body.In fact, many people have misunderstandings about blood donation, let’s take a look together.

Misunderstanding 1: Blood donation will cause infection diseases such as AIDS and hepatitis

The safety of blood donation mainly depends on three points to ensure: First of all, when blood donors collect blood, a disposable disinfection syringe is used. After strict disinfection, it will be destroyed in concentrated.And manufacturers who produce blood collection consumables are strictly approved by the national health department;

Second, use one person and one needle when donating blood, instead of multiple people, to avoid cross -infection;

Third, blood donation is a process of output, and the blood is pulled out of the body, so infectious diseases are not contagious.

Misunderstanding 2: After donating blood, anemia is prone to occur after blood donation

The human body has a complete blood system, and blood can be self -sufficient.Healthy adults donate about 200 ~ 400ml each time, accounting for only about 5 ~ 10%of the blood capacity of the whole body, and will not cause any harm to the human body.Moreover, the blood capacity can be supplemented within 2 hours after human blood donation, and red blood cells, hemoglobin, and serum iron within 3 months can return to the level before blood donation.Therefore, blood donation will not only cause anemia, but also because the hematopoietic function is enhanced, it is good for health.

Misunderstanding 3: Blood donation will lead to a decline in immunity

A large part of the saying that blood donation will reduce the immunity of blood donors comes from considering that some white blood cells and antibodies will be lost when blood donation, because they can help the human body to effectively resist the infection of primary microorganisms, forming the human body’s "immune defense line".Indeed, blood donation will cause the human body to lose part of the white blood cells and antibodies in the blood, but from the usual amount of blood donation, the ratio of white blood cells and antibodies that the human body is actually lost is very small.The moisture and inorganic objects lost after blood donation will be supplemented in 1 to 2 hours. Protein and other proteins such as antibodies in plasma are synthesized by the liver. It can be supplemented in one or two days, and white blood cells will quickly return to the original level.

Misunderstanding: Blood donation will make people "addictive"

Some people say that after blood donation, our hematopoietic function is constantly enhanced, which will cause blood vessels to swell. If it does not pass the blood drawing method, it cannot reduce this discomfort.In fact, this "blood donation will be addicted" is wrong, and there is no basis.

More than ten years ago, the blood collection agency had conducted a survey. The blood donation of 200 ~ 400ml was just a small stimulus to the human body. It would create a large amount of red blood cells to generate hormones and increase the number of bone marrow manufacturing red blood cells.Even without blood donation, red blood cells are constantly aging and death, and it will have a normal balance process in the body.

At present, there are tens of millions of blood donors all over the world, and there have been no cases of "addictive" through blood donation to produce physiological "addiction".

Misunderstanding 5: It must be empty before donation, and supplement after blood donation

It is not a process to donate blood and go to the hospital for blood testing, and it does not require an empty stomach.If you donate blood on an empty stomach, it will cause adverse reactions such as dizziness because of low blood sugar.Before donating blood, in order to allow the blood donor to reach a better state, a large amount of greasy foods must be avoided, causing high blood lipids in the blood, a light diet before blood donation, and maintaining sufficient sleep.

Some people ask, do you need to make up for blood donation? In fact, with the nutritional conditions and living conditions of modern people, healthy adults do not need to supplement any nutritional products after donating blood.However, after blood donation, you need to pay attention to six points: ① Keep the needle eye cleaning, do not rub; ② Do not take a bath within 24 hours; ③ Do not perform severe sports activities and heavy physical labor; ④ Do not work high temperature, high -altitude operations, etc.Drink, eat lean meat, liver and other foods; ⑥ Be careful not to overeat.

Misunderstanding 6: Blood donation may affect sperm vitality

Normal healthy adult men’s blood donation will not affect sperm vitality, but it has certain benefits for physical health.One to 2 days after blood donation, the human body can be added with blood capacity and blood cells, which will not affect pregnancy and fetal development.In addition, the human fertility ability is mainly affected by whether the reproductive system is normal and the development conditions of fertilized eggs have nothing to do with whether to donate blood.
