For thousands of years, our society has been working for hunger and the food problem has never been solved.
In famine years, blood loss (blood donation) will definitely endanger health. Plasma in blood is the essence of food digestion, and insufficient red blood cells is anemia. So it is reasonable for the older generation to say that blood donation is harmful to health.
Nowadays, for most people, they are afraid to eat when they see food. Dieting is the mainstream.
A healthy person, donating blood is not harmful to health, and does not need special conditioning after donating blood.
Donate 400 ml of blood, and the plasma inside is the digestive product of a meal at most. People who are not anemic (will be tested for anemia before donating blood) have enough red blood cells, and only the extra part is donated, so there will be no problem with white blood cells and platelets.
Many people are overnourished, and the nutrients in their blood have to be stored in fat.
Donating a little blood will do no harm to healthy people.
It is best not to publicize the health benefits of blood donation to blood donors. I always feel a little far-fetched.
Blood donation will not affect the health of blood donors.
I have donated blood for 22 years, 180 times, and now I donate platelets twice a month, and I still insist on donating blood.
The advantage of donating blood for so many years is that you can enrich your life by participating in and publicizing the process of donating blood without compensation.
Know some blood knowledge, pay more attention to your health, pay attention to a light diet and keep your blood fat low.
After donating blood, if I or my family use blood in the hospital, I can reimburse the cost of blood use.
If you donate more blood, you can get a reward from the state.
