Surprising Health Benefits of Donating Blood

During the summer months, we often hear that the American Red Cross is in greater need of blood donations. If you're thinking about donating blood, here's a surprising fact that many people don't know: donating blood doesn't just help the person who receives it, it improves your heart health as well. 

Why is donating blood heart healthy? When you donate blood it reduces your blood volume and promotes healthy blood viscosity, or blood flow. Plus, if you’re a male or a postmenopausal woman, periodically donating blood is extremely important because it helps to reduce excess iron in your blood.

Why Is Reducing Iron Levels by Donating Blood So Important?

Your body stores iron in your muscles and other tissues and unless it’s lost through menstruation or by donating blood, toxic levels can accumulate in your system. A Finnish study examined 1,900 men ages 42 to 60 for five years. What they found is that men with excessive levels of iron were more than twice as likely to have heart attacks. Plus, every one percent increase in iron translated into a four percent increase in heart attack risk, making the health benefits of donating blood even clearer.
Another related issue is that about 10 percent of American adults carry the gene for hereditary hemochromatosis—or iron overload. Their physicians are often perplexed by their symptoms of fatigue, abdominal pain, organ failure, immune dysfunction, skin bronzing, irritable bowel syndrome, menstrual irregularity, hair loss, and explosive diarrhea. 

To find out if your iron levels are healthy, ask your doctor to perform a special iron test called serum ferritin. Ideally, you want your iron level to be less than 80 mg/L (for women) and less than 90 mg/L (for men). If your results are above 100 mg/L, to help remove the excess iron, donate blood one to three times per year. If your level is more than 400 mg/L, ask your doctor to check for hereditary hemochromatosis.

If you’re interested in helping decrease the blood bank shortage and the health benefits of donating blood, you can contact the American Red Cross to find a blood donation opportunity near you. It's also a good idea to check with your doctor first to get his or her okay before you donate.

Now it’s your turn: Have you experienced the benefits of donating blood?
