If you are healthy person who has been exercising regularly, after you donated blood, you wonder whether you can exercise right after that. The answer is no. You should only exercise after at least 5 hours of resting. Do not run, swim, do weight training or other rough movements during the first 5 hours of donation. In fact, even after that period, your competitive performance in the court or track may be affected.
Red blood cells are the oxygen carrying cells. They can take two weeks or longer to fully return to normal. You can donate platelets (apheresis donation) every two weeks â up to 24 times in 12 months. Platelet and plasma components are regenerated in the body more quickly than red cells. Platelets will return to normal levels within 24-48 hours of donating.
