What are the benefits of blood donation

The slogan "Donate blood for free, no glory" is very loud, but every time you pass by the blood donation van, you are still afraid to roll up your sleeves and take a step.

The benefits of blood donation

Reduces blood viscosity

Scientific blood donation, especially single donation of components such as red blood cells and platelets, can significantly reduce blood viscosity, speed up blood flow, increase cerebral blood flow, and alleviate or prevent hyperviscosity.

Enhancement of hematopoietic function

After multiple blood donations, the body becomes more responsive to blood loss and replenishes blood faster, thus keeping the hematopoietic function in a vigorous state.

Reduce the occurrence of cardiovascular diseases

Excess iron and copper in the blood is an important factor in triggering heart disease, and an appropriate amount of scientific blood donation can reduce the excess iron and copper in the blood, thus reducing the occurrence of cardiovascular diseases.

Promote metabolism and prolong life

A large number of blood cells are aging and dying in the human body every moment, while new blood cells are being born and growing. After blood donation, the blood in the human body is reduced, which will stimulate the hematopoietic organs to accelerate the production of blood cells, and the newly produced young blood cells can not only deliver more oxygen and nutrients to the whole body, but also have a strong ability to swallow viruses and resist diseases, thus prolonging life.

Disadvantages of blood donation

Fainting

For first time blood donors, fainting can be induced if they are too nervous or overly tired before donating blood, or if they are in a state of hunger, and they need to rest for half an hour after donating blood to prevent fainting on the way.

Anemia

If the donor is malnourished and gives blood too many times in a short period of time, anemia may occur.

Infectious diseases

In the process of blood donation, if sterilization is not strict and blood drawing equipment is shared, the possibility of contracting diseases cannot be ruled out, but this does not exist as long as it belongs to a regular national blood collection agency.

Precautions for blood donation

1. Before donating blood, be careful to get enough sleep and do not do strenuous exercise. 2. Before and on the day of blood donation, you should eat your usual diet, but with low fat, no fatty foods, non-vegetarian foods and legumes, and especially no alcohol. 3. Do not donate blood on an empty stomach. You may eat some light food such as rice, steamed buns and pickles. 4. Donors should not take anti-platelet aggregation or drugs that inhibit platelet metabolism, such as aspirin, vitamin E, anti-inflammatory pain, pansentin, aminophylline, chloramphenicol and anti-allergy drugs one week before donating blood. 5. After blood donation, apply pressure at the needle hole for 3-5 minutes. Do not do strenuous activities for a day or two. The needle hole should be kept clean to avoid infection. The bruising that sometimes occurs around the needle hole is caused by a small amount of blood spilling outside the blood vessel and will be absorbed naturally.

What are the circumstances under which you cannot donate blood temporarily

1. Those who have had a tooth extraction or other minor surgery within half a month. 2. Women who are 3 days before or after menstruation, during pregnancy, less than 3 months after miscarriage, and less than 1 year after delivery and breastfeeding. 3. Those who have recovered from cold or acute gastroenteritis for less than 1 week, those who have recovered from acute urinary tract infection for less than 1 month, and those who have recovered from pneumonia for less than 3 months. 4. Transfusion of whole blood and blood components within the last 5 years. 5. Those who have not completed six months after larger surgery, those who have not completed three months after appendectomy and tonsil surgery.

Warm Tips

Strictly speaking, as long as men and women who have undergone a physical examination and meet the health standards donate 200-400 ml of blood at a time with an interval of at least 3 months between donations, there is no impact on their health.
