Blood donation is good for health.

In the street, we often see blood collection vehicles in some hospitals, and there are also many reports of unpaid blood donation in the usual reports. Moreover, the state encourages voluntary blood donation, and many benefits of voluntary blood donation are mentioned in the propaganda. From this perspective, blood donation is a very glorious and proud thing, but we ordinary people have doubts about whether blood donation is harmful or beneficial to our health. Then, let's see what benefits proper blood donation has on our health.

We know that all tissues of the human body are constantly working and growing, so these tissues include our cells, blood, skin and hair, and so on. When these creatures participate in our life activities, there is a certain upper limit of times and time period. For example, the human body has a cycle of 28 days, so when these creatures reach the upper limit, their lives will end, but at the same time, they will be replaced by new creatures. Intuitively, what ordinary people can understand is that our skin will lose dandruff, our hair will fall off, and so on. These are the reasons why the new body will replace the aging body.

In fact, blood is the same. Scientific facts have proved that a proper blood donation only accounts for a very small part of human blood. The temporary reduction of a small amount of blood does not affect the normal circulation of human blood and is harmless to human body. On the contrary, after blood donation, the self-healing function of the human body will be strengthened to make up for what we have lost. This will strengthen our physique and resistance. At the same time, blood donation will stimulate the hematopoietic function of the kidney and produce more fresh blood to make up for the part of blood we lost. At the same time, it will promote metabolism, strengthen newborn blood cells, make our body reach a balanced state as soon as possible, help to exercise the body's resistance and strengthen various physiological indicators. Therefore, blood donation is conducive to enhancing physical health and physique. At the same time, we also know that when ordinary people donate blood, medical staff will have some simple physical tests to judge whether our bodies are suitable for blood donation. So don't worry too much when donating blood. After all, blood donation is a public welfare undertaking that benefits the country and the people.

Therefore, proper blood donation is beneficial to the body, it can exercise our body and enhance our own resistance. At the same time, it is also a glorious and meaningful thing.
