Giving blood is a powerful way to help others. Each donation can save up to three lives, and people need blood every few seconds. Beyond helping others, donating blood also has health benefits for you.
1. Helps Regulate Iron Levels
Each donation removes about a quarter of a gram of iron, which your body replenishes naturally. This helps maintain healthy iron levels and can reduce the risk of heart disease and stroke. Some people, like pre-menopausal women or those with anemia, may need to increase their iron intake before donating.
2. Improves Circulation
Regular blood donation can support healthy blood flow, helping prevent blockages and reducing strain on blood vessels. Improved circulation also helps distribute nutrients more efficiently, supports longer periods of exercise before fatigue, and maintains a stable body temperature.
3. May Reduce Cancer Risk
High iron levels have been linked to an increased risk of certain cancers. By lowering iron through donation, some studies suggest your cancer risk may be reduced over time.
4. Provides a Mini Health Check
Before donating, staff will check your pulse, temperature, blood pressure, and iron levels, and review your medical history. After donation, your blood is screened for infections and unusual antibodies. While this isn’t a substitute for regular medical care, it offers an extra layer of reassurance.
5. Burns Calories
Donating blood uses energy—about 650 calories per pint donated. While it shouldn’t replace regular exercise or weight management, it’s a small added benefit.
