It significantly reduces your chance of cancer for life, even though it only takes 48 hours to completely replace the lost blood cells.Even better, giving blood burns calories. A LOT of calories. One session of donating can burn up to 650 calories, the same as 45 minutes of running or a third of a woman’s recommended daily intake.This is why you shouldn’t think of giving blood as a chore, but rather as really, really effective exercise.Wake-up exercise workout NEXT ON HEALTH24X Experience a contact lens that feels like nothing 2016-10-24 12:49 More: LifestyleYour Blood advertisement Read Health24’s Comments Policy Comment on this story 2 comments Comments have been closed for this article.
