These problems are more significant in men than women as women have menstrual cycles. Henceforth, they lose blood without donating.

Blood donation at least once an year reduces the heart attack by 88% according to the study


In the case of a healthy person, the link between a fit person and decreased cancer risk is slim. But some researchers say that donating blood helps in reducing the risks of cancer. The reason behind the reduction of risk is the reduced level of iron.
