What are the disadvantages of men donating blood?

Blood is one of the most important fluids in the body. It is a tool for the circulation of nutrients in the body. In modern life, more and more people are suffering from insufficient blood. This may be caused by reduced blood production due to personal reasons or blood outflow due to trauma. The fastest way to solve this problem is to donate blood. However, blood donation also means blood loss for people. Men should be cautious when donating blood. Let's take a look at the disadvantages of men donating blood.

In general, the disadvantages outweigh the advantages. The reasons are as follows:

1. Benefits: The increase in hospital blood reserves can help more people who need blood transfusions, and some rare blood types become more precious.

2. Disadvantages: Blood donors have a greater chance of being infected with viruses. Unhygienic needles and inadequate self-cleaning by medical staff are common in China. Few hospitals provide comprehensive blood tests when donating blood. Blood donors with low potassium levels are absolutely unsuitable for blood donation. After donating blood, they often feel dry mouth and drink water, which leads to low potassium levels in the serum and causes shock, which can lead to death in severe cases. Such tragedies have been reported in newspapers. Blood, as a transport unit for nutrients and oxygen in the body, must be kept full at all times, but people often lack oxygen due to anemia. Blood cannot reach the extremities; the human body's red blood cell cycle is 100-120 days, and irregular blood donation will disrupt the body's production of new red blood cells, because the human body needs to quickly replenish the lost red blood cells to maintain normal functioning of the body; one of the modern scientific studies on human aging believes that: human genes determine that there is a certain upper limit to the renewal of various cells, and when this upper limit is reached, human life will end, so blood donation will undoubtedly speed up this renewal rate and cause the human body to age faster. Speaking of the matter, blood donation is beneficial to others, but it is harmful to oneself.

In addition, disease screening before donating blood is also beneficial for people. In order to ensure the quality of donated blood, some blood-transmitted diseases must also be checked, so you can also understand some of your own conditions. At the same time, you can also determine your blood type.
