I'm going to donate blood this coming Tuesday as part of a blood donation camp. How long should I wait before I resume working out?
If you feel dizzy or lightheaded during or after post-donation exercise, lie down and elevate your feet. Make sure that you are drinking fluids and contact your blood donation center or health-care provider if you are concerned about any symptoms. Many blood donors find that they need to reduce the intensity or the duration of their first few post-donation exercise sessions.
