A bite to eat and refreshing drink are an important part of your recovery after you donate blood. That light meal may be a small token, but it accomplishes several important tasks. It keeps you sitting still, mitigates the light-headedness you can experience, helps you replace fluids and starts you off with a reminder of how important it is to drink plenty of fluids and eat a healthy meal for the next few days.
To Say Thanks
Donating your blood can save a life. All too often, blood supplies run critically short. Because of your free, potentially life-saving gift of blood, many blood donation organizations show their appreciation for your time and effort with a light snack and drink.
Prevent Wooziness
After giving blood, you may experience some light-headedness, dizziness and weakness. The American Red Cross says that after you give blood, you should avoid strenuous activity or even lie down if you're feeling faint. A light snack while sitting and resting after giving blood is a handy way of keeping you still to regain your composure. The Red Cross wants you to stay put for at least 15 minutes after donating. Eating something might also give you a little of your strength back.
Fluid Replacement
Providing you with something to drink immediately after you give blood begins to replace the fluid you just lost. It also serves as a healthy reminder that you need to continue drinking plenty of fluids for the next 24 to 48 hours. Doing so will help prevent low blood pressure.
Iron Replacement
Although you may be given only a light snack, eat a hearty meal soon after giving blood to begin replacing your iron levels. Iron is shed through blood, but it is essential to replacement and maintenance of your red blood cells.
