What are the health problems that can lead to regular blood donations?

1. Components of blood.

Blood in the human body is made up of plasma and blood cells. 90-91 in plasma is water, and other solid substances include plasma proteins, inorganic salts, and small organic substances such as hormones, nutrients, and metabolites. Blood cells can be divided into three categories: red blood cells, white blood cells and platelets, of which the largest number is red blood cells, accounting for about 99 of the total number of blood cells.

2. The lifespan of various blood components.

Whether a person participates in blood donation or not, his blood is constantly metabolized, and the lifespan of various cells is:

120 days for red blood cells; neutrophils 4 for 5 days; lymphocytes 10 200 days;

Blood cells are constantly repeating the process of rebirth, aging, and death, so as to maintain a dynamic balance of blood.

3. The composition of human blood volume.

Human blood is mainly composed of two parts: circulating blood and reserve blood.

Circulating blood: The blood circulating in the heart and blood vessels, accounting for about 80% of the body's blood volume, is mainly used to maintain the normal physiological functions of the human body.

Reserve blood: stored in the liver, spleen and other organs in the capillaries of the blood, accounting for about 20 of the body's blood volume, in general, these blood flow slowly, and do not participate in the blood circulation, when the body has blood loss or strenuous exercise, the reserve blood will be released into the blood circulation, replenish the circulating blood volume, to meet the needs of the body.

Healthy adults have about 7 8 percent of their body weight. An adult weighing 60 kilograms, the total amount of blood in the body is about 4800 ml, a blood donation of less than 400ml, blood loss does not exceed 10 of the total blood volume, through the body's own compensatory mechanism to make the blood volume gradually recover, will not affect health. Usually, only when the blood volume is lost by more than 20% can the body experience a series of symptoms of hypovolemia.

Practice has shown that people in good health have a greater tolerance and self-regulation of blood loss.

It doesn't hurt to donate plasma in general. Plasma donation refers to the blood donor first donating whole blood at a special blood donation point, and then separating the blood cells in the blood and then transfusing it back into the blood donor's body, and the remaining part is plasma. Plasma donation is very fast because only human plasma is drawn, not red blood cells, and because more than 90% of the plasma is water, plus the body's hematopoietic tissue will automatically accelerate hematopoiesis.

Generally, in two to three days, the water can be restored on the same day, and the protein is eaten normally for two or three days.

can be recovered. Appropriate plasma donation is beneficial, which can promote blood renewal, reduce blood lipids and blood viscosity, effectively prevent the occurrence of cardiovascular and cerebrovascular diseases, and promote the body's metabolism. It can also significantly improve blood tension.

When plasma transfusion is required, it is still necessary to rely on plasma donation to achieve it. It is recommended that young people can donate plasma appropriately, but should seek out regular blood donation departments to avoid contracting diseases.

The normal menstrual cycle is influenced by the pituitary gland, ovaries, and endometrium, called the hypothalamic-pituitary-ovarian axis. As long as it is under normal physiological conditions, menstruation is according to the cycle of endometrium proliferation and shedding, and the cycle of hyperplasia and shedding after ovulation is menstruation. Generally, blood donation will draw 200-400ml of blood each time according to the state of human condition, and the blood will not affect the health nor the endocrine environment, nor will it affect the process of endometrial hyperplasia and shedding, nor will it affect ovulation.

Under normal circumstances, donating blood does not affect health, let alone the menstrual cycle, and of course, it does not delay menstruation. Therefore, this kind of blood donation is 200-400ml of blood each time in the health condition, which will not have any impact on health. As long as the physical condition meets the recommendations for blood donation, there is no problem, and of course it will not affect menstruation, let alone delay menstruation.

In some cases, because menstruation is also affected by the pituitary gland nerve, if the pituitary gland function is abnormal due to excessive emotional tension, anxiety, and poor sleep after blood donation.

Many people think that the amount of blood in the body will be reduced after donating blood, and it is easy to cause anemia, which will also make their body weaker, so donating blood is harmful to the body, in fact, this idea is wrong, when donating blood, although the amount of blood in our body will be reduced, but because our blood is renewable, in the face of the reduced blood in the body, as long as we usually eat some nutritious food, the blood will be slowly recreated. Blood donation will not only not affect our body, but will also bring benefits to our physical health.

What are the benefits of donating blood?

Prevention of cardiovascular and cerebrovascular diseases.

Relevant research statistics show that after donating blood, the blood viscosity and cholesterol content in the body will be reduced accordingly, so for some people with cardiovascular and cerebrovascular diseases, blood donation can also protect our heart and cerebrovascular health, reduce the viscosity of blood, increase the vitality of blood regeneration, make the body healthier, and people more energetic.

Improve one's own hematopoietic function.

But after we donate blood, the blood in the body will be reduced, Zhang Yuxin, our brain will only match our body's hematopoietic stem cells to create some fresher blood, in order to supplement the body's demand for blood, in the production process can also promote the body's metabolism and blood circulation, so as to improve their own hematopoietic function.

Lowers blood lipid levels.

If the blood lipid content in the body is relatively high, it is also easy to have high blood lipids, that is to say, some fats and toxins may be precipitated on the blood vessel wall, which is easy to block the blood vessels, and it is also easy to have arteriosclerosis, but if you donate blood regularly, it can also greatly reduce the content of blood lipids and avoid the appearance of arteriosclerosis.

From the perspective of health, regular blood donation is also good for our body, and from the perspective of citizens' obligations, selfless blood donation is also a contribution made by citizens to the country.
