After Blood Donation: Why You Should Avoid Strenuous Exercise

Heavy exercise post‑donation is discouraged because it can:

1. Raise blood pressure and strain the puncture site → hematoma risk.
2. Increase bleeding from the needle site.
3. Cause dehydration, lowering blood volume further → lightheadedness.
4. Worsen muscle soreness and fatigue from blood loss.
5. Drop blood pressure further → fainting risk.
6. Delay overall recovery.

Instead: Light activity (walking, gentle stretching) is fine. Consult the donation center or your doctor for personalized guidance on resuming intense workouts.
