Wounds and cuts heal faster if there is no pressure on them and if they are kept relatively motionless. Movement disrupts the formation of the new blood vessels. Bandages keep the wound clean, keep harmful bacteria out, and maintain moisture to prevent your skin from drying out. Bandages should be changed daily.
You must wait at least eight weeks (56 days) between donations of whole blood and 16 weeks (112 days) between Power Red donations. Platelet apheresis donors may give every 7 days up to 24 times per year. Regulations are different for those giving blood for themselves (autologous donors).
This deficiency can make you feel tired: this is why, as well as asking male donors to wait 12 weeks and female donors to wait 16 weeks to donate whole blood, we also test your haemoglobin levels every time you give. We make sure that your haemoglobin level is above 125g/l for women and 135g/l for men.
