Science Fiction Network June 14 (Wang Ziyu) Blood is an irreplaceable precious medical resources. Those who donate blood freely saved countless lives with their blood. To commemorate every free blood donation, he was set up to the World Bloody Day on June 14th each year. On this day, the Nobel Laire Nobel winner of the ABO blood type system, Karl Randstana's birthday.

In recent years, there are more and more blood donation in my country, from 328,000 in 1998 to 15.53 million in 2020, an increase of 47 times. But many people still have a lot of doubts about the free donation of blood. Will blood donation affect their own health?

The World Health Organization believes that the total blood volume of an adult with a fitness of 50 kg is about 3500ml-4000ml. If a blood donation is 400ml at a time, it does not exceed 13%of its total blood volume, and it will not affect the body. In addition, scientific regular blood donation can effectively promote blood regeneration, reduce blood lipids and blood viscosity, and improve self -renewal ability of the body.

At present, 34%of the blood of blood donors in my country is used in patients with cancer and hematological diseases. If no one has donated blood, 45,000 leukemia children in cure will be directly declared torture. Because the blood is currently not artificially manufactured, it can only come from the voluntary donations from the healthy people. Each blood transfusion can save up to 3 people's lives.

Every year, there will be different themes for blood donation days. The theme of the first world blood donor day is "donating blood, gifts for life, thank you". The theme of this year is "Blood donation is a unity, joining us and saving life." In addition, the global event this year's blood donation day will be held in Mexico City, Mexico.
