So what about your blood supply?
I’ve been thinking about this from since two weeks ago when I last donated blood at the Red Cross. Losing a pint of blood is a pretty stressful event from a physiological point of view. Donors are told to drink plenty of fluids and eat lots of iron-rich food in the week following their donation. Now we know blood loss stimulates your body’s red-cell production. Question: does regular blood loss from donations have a similar effect on bone marrow (where blood cells are manufactured) as physical exercise on muscles? Do regular donors have stronger blood-manufacturing capacities than their non-donor counterparts? Does the body “overcompensate” for periodic blood loss by becoming more efficient/powerful at manufacturing/replenishing your own vital fluids?
If so, what are the health benefits for having a stronger-than-average blood-production capacity?
