- Eat a healthy meal: Have a balanced meal a few hours before donating.
- Stay hydrated: Drink extra water the day of donation.
- Bring ID: Most centers require a form of identification.
- Check medications: If you take medicines, check with the center or your doctor whether they affect eligibility.
- Rest: Get a good night’s sleep beforehand and avoid heavy exercise immediately after donating.
Following these tips helps make donation fast and safe—both for you and for the person who will receive your blood.
A few practical notes: if you usually have low iron, consider iron-rich foods in the days before (or ask your doctor). Wear comfortable clothing with a sleeve that can be rolled up. If you feel faint or dizzy after donating, lie down and raise your feet and let staff assist you. Recovery snacks and fluids are provided at most centers — they help you stabilise quickly.
If you have recent travel, illness, or dental work, check local deferral rules before going to the center. Policies vary by country and some deferrals are temporary; staff will explain any waiting periods.
