Nowadays, many cities have blood donation trucks on the streets, and as more people donate blood, you can often hear rumors that blood donation is addictive. However, can blood donation be addictive? People who have never donated blood have fears and doubts about it, but those who donate blood regularly are happy to do so.
The phenomenon of blood donation addiction
We often see on TV and in the newspapers that a very small number of people are addicted to blood donation, mainly because they look forward to the day to donate blood, and if for some reason they don't donate blood for several months in a row, they feel uncomfortable and feel better after donating blood. However, is this really the so-called blood donation addiction?
Is it true that blood donation is addictive?
In fact, there is no adequate medical theory to support blood donation addiction. Normal blood donation is not addictive, and people who donate blood regularly will feel comfortable because blood donation accelerates the renewal rate of blood, which can play a role in blood purification.
Excessive and frequent blood donation can be "addictive"
Although there is no evidence to prove the existence of blood donation, it is believed that regular and frequent blood donation may excessively strengthen the blood production function in the body, causing the blood vessels to swell and only continue to pump blood to reduce discomfort, perhaps this is the reason for the current rumor of blood donation addiction.
Benefits of Moderate Blood Donation
Proper blood donation can prevent and alleviate hyperviscosity, cardiovascular diseases, and can reduce the incidence of cancer. The human blood is constantly metabolizing. Every moment, many blood cells are aging and dying, while a large number of new cells are being generated to maintain the balance of human metabolism. After blood donation, due to the strengthening of the hematopoietic function, the lost blood cells are quickly replenished, which not only accelerates the renewal rate of blood but also plays an effective role in blood purification.
Dangers of excessive and frequent blood donation
As the regulation of various body fluids, excretion of metabolic waste, etc., all depend on blood red blood cells for transportation, and the body's defense and immunity and hemostasis are also done by blood. Excessive and frequent blood donation can easily lead to long-term ischemia in the body, and the quantity or quality of red blood cells decreases, thus affecting the transport function of blood to varying degrees and causing a series of pathological changes. The body's defense immunity will also be reduced, and it will also be more prone to illness.
