Short Answer
Yes. Drinking plenty of water before donating helps maintain your blood volume and reduces the chance of dizziness or fainting.
Detailed Explanation
Hydration is one of the simplest ways to make blood donation easier. Since about 450 mL of blood is collected during whole blood donation, being well hydrated helps your body adjust more comfortably.
Most blood banks recommend drinking several glasses of water during the few hours before donation.
Continue drinking fluids after donating as well.
