Will a person's health be affected if he/she donates blood regularly to Blood services? Some people say that it takes a while for new fresh blood to be replenished into our body once it has been extracted. I did feel slightly dizzy after blood donation but I feel happy that by donating blood, I am actually saving lives.
I noticed that after blood donation usually we are asked to stay behind for half hour and have something sweet to eat and drink before heading back to doing our regular routines daily lives. We were advised not to do any heavy work at least for a good 24 hours or else the needle wounds might start bleeding again. I find that it also depends on the technique the blood phlebotomist uses to draw blood. Sometimes, after blood was drawn, I could go straight back to work without feeling any pain at all. Others are not so good and I do feel slight pain and black veins mark for 24 hours.
