Eat normally, drink water, sleep well, bring ID. What to do (and skip) in the 24 hours before donation.

In the 24 hours before donation: - Eat normally, never donate fasted. Iron-rich food helps (see what to eat).

Drink plenty of water, 500 ml extra in the 2 hours before helps veins and recovery.
Sleep well the night before.
Skip alcohol for 24 hours.
Skip the heavy workout right before (light activity is fine).
Bring ID, any photo or official ID works. On the day, tell the screening doctor honestly about any medication, recent illness, tattoo or travel. Everything you say is confidential. Related: during donation · after donation

What should I do before donating blood?

Sleep well, eat a full meal within a few hours, drink extra water, and skip alcohol for 24 hours. Bring ID; the centre handles the rest.

Can I drink tea or coffee before donating blood?

Yes, in normal amounts. What matters more is water, an extra glass or two before donation makes the vein easier and the donation smoother.

Should I skip exercise before donating blood?

Light exercise is fine; avoid a heavy workout right before, and skip heavy lifting for the rest of the day after donating.
