A cold is a bacterial or viral infection, and donating blood does not give people the associated virus, so there is no necessary relationship between blood donation and cold.

Some people will say that after donating blood, the resistance decreases, causing colds.

Yes, the white blood cells in the blood are antiviral, but the blood collected with each blood donation only reduces the white blood cells by less than 10%. It will not affect the body's ability to resist diseases.

If there is an invasion of bacteria or viruses, the number of white blood cells in the blood will increase dramatically, and the most important thing to do when you go to the hospital for a blood test is to roughly determine whether it is an inflammatory infection based on the number of white blood cells.

Colds have an incubation period, and many illnesses are symptomatic or undetectable long after infection.
