JEFF: I donate blood every 56 days and would like to know if it affects your running? I only run 3 miles three times a week and for some reason I just have no energy for about a week after I donated blood … is it in my head or can it affect me that long?
I'm female, about 5.8 and weighs 147lbs … if that will help.

ANN: A standard blood donation will not usually be felt in everyday life. Running requires much more oxygen and the blood donation has removed just enough oxygen carriers (red blood cells) to make a difference. According to medical experts, your body replaces the red cells within about 2 weeks.
What you are feeling is normal. I suggest going slower and taking more walk breaks during that replacement period. I would not donate blood if you are running a long run or a long race within the two week period after giving blood.

Ann – One thing you might consider is donating blood platelets rather than red blood cells. I am a regular donor of both. I have found that after a RBC donation, I am more tired and need to take it easy for 3-4 days but after a blood platelet donation, I can usually run within 24 hours with no ill effects at all. Depending on your blood type, the blood center in your area may need a platelet donation more than they need a RBC donation. It takes longer to donate but you recover more quickly. Given that you seem very committed to donating (every 56 days) you should know that you can donate platelet more often (every 10-14 days or 24 times a year most places). Last year I donated 20 – double units of platelets.
Debra: thanks much for letting us know about donating platelets.
