For many people it my be "all in their head" but we must remember that everyone reacts differently to many things, giving blood included. The first and only time I gave blood, I had sufficient iron in my blood and was not in the least squeamish about the sight of my own blood (I used to hold up my own vein for the doctors to take samples). However it took me over 1 week to recover, I had brain fog and felt lethargic. The exam I took the next day (yeah I know!!) was not at all difficult but I did rather poorly, it took me twice as long to come up with the answers, which is not normal. This for me was definately not psycological. I have not had this result with any of the tests that I have had since then either, some of up to five vials.

For most people it will not be a problem, however for a few, the loss of blood may trigger a reaction in something which is not normal with their bodies. It is easy for those who are in the medical profession to say that it is all psycological, which it is in many people, but without knowing everything about a person's body (which we can't) we should not say that it is only in their head.

Even the ancients knew that blood letting did some strange things sometimes. <img src="/images/graemlins/wink.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" />
