Donating Blood and Exercise: What to Know Before and After Giving Blood

Blood donation is a selfless act that can save lives and improve the health of patients in need. To ensure the safety and well-being of donors, it’s crucial you understand the importance of limiting exercise before and after blood donation. 

Let’s walk you through some precautions to take prior to your appointment and provide you with some pointers to plan your exercise routine around the donation process. This will ensure a safe and successful donation experience.

Before Donating Blood

Stay Hydrated and Rest: Maintaining proper hydration and getting enough rest before your appointment is important. Strenuous exercise can deplete your body’s fluids, and vigorous physical activity can also temporarily affect your heart rate and blood pressure. It is essential to drink plenty of fluids and eat normally in the days leading up to your donation appointment and get a good night’s rest before you visit us. These measures help ensure that your body is well prepared and can provide you with an optimal donation experience.

Fuel Your Body: An iron-rich diet lays the groundwork for a healthy iron balance, so eat a nutritious meal before your appointment. If you want to maximize your iron absorption, consume iron-rich foods along with plenty of vitamin C-rich foods, such as broccoli, kale, mangos, kiwi or orange juice. Keep in mind that a higher dose is needed to replenish what is lost during a blood donation. Learn more.

Avoid Working Out: Before donating blood, it’s advisable to avoid strenuous exercise or intense physical activity — regardless of what type of donation you’re giving. Rigorous exercise can temporarily elevate blood pressure and heart rate or transiently change hemoglobin levels.

After Donating Blood

Take It Easy: Avoid vigorous exercise or heavy lifting for about 24 hours after donation. Your body needs time to replenish the fluids and components that you gave. Strenuous exercise immediately following blood donation can put additional stress on your body and potentially prolong recovery. And who wants that? It is advisable to avoid heavy lifting or intense activities so you don’t put a strain on your blood donation arm. Are you a fitness guru? Treat your donation as part of your recovery process.

Listen to Your Body: Every individual’s body reacts differently to blood donation. While some donors may feel perfectly fine and resume their regular exercise routine shortly after donating, others may experience temporary fatigue or weakness. It is crucial to listen to your body and adjust your exercise plans accordingly. If you feel lightheaded, dizzy or fatigued, take time to rest and recover before resuming intense exercise.

Stay Hydrated and Eat Something: Drink plenty of fluids (non-alcoholic) after donating blood to help your body recover and maintain good circulation. Enjoy a healthy snack or meal after donation to replenish your energy levels.

Simple, right? By abstaining from or minimizing exercise before and after blood 
donation, you contribute to a safe and successful donation experience for yourself and the recipients of your generous gift. After all, a small pause in your exercise routine has the benefit of saving someone. Just remember to hydrate, rest and always listen to your body.
