What are the advantages and disadvantages of donating blood?

At present, China has been advocating people to donate blood voluntarily. The collected blood will be replenished in the blood bank and used for medical emergency. Moreover, human blood can be continuously regenerated, and donating blood in moderation will have certain benefits to the body. However, not everyone can donate blood, and some people will also have disadvantages after donating blood. Below I will specifically talk about this knowledge for everyone.

1. Improve body immunity

Improving human immunity is an important benefit of donating blood in moderation. Donating blood in moderation can improve mental health, regulate the balance of the neurohumoral and endocrine systems, keep all organs in good condition, and significantly improve the body's self-immune ability.

2. Reduce the incidence of cancer

Donating blood in moderation on a regular basis can also effectively reduce the incidence of cancer. This is because if the blood in the human body is not renewed for a long time, some harmful substances will be deposited, which will induce cell cancer. After donating blood, the blood's regeneration capacity will increase, the number of harmful substances in the body will be significantly reduced, and the possibility of human cells becoming cancerous will also be significantly reduced.

Disadvantages of donating blood

1. Affect brain function

Although donating blood can help more people and has certain benefits to your own body, it also has obvious disadvantages. When the amount of blood in the body decreases, the brain will not be supplied with enough oxygen. At this time, ascorbic acid will be produced in the body, which has adverse effects on human cells, causing brain function to decline, memory to decline, and thinking reaction ability to slow down significantly.

2. Prone to infection

Although the country now advocates voluntary blood donation, the blood donation process in many areas is not standardized, and multiple blood donors use the same syringe. In this case, blood infection is particularly likely to occur, especially when other blood carries viruses. These viruses can enter the body of a healthy person through the syringe and infect him with the disease.
