By Michael A. Smith, MDDonating blood actually offers many more health benefits than most would expect.
Not only will you help someone in need of blood, but you'll also be helping your own body optimize its health and wellness.
This is an interesting fact that many people are completely unaware of.
Below, we'll explore the top three health benefits you can reap from the act of donating blood.
Donating Blood Protects Your Heart by Reducing Oxidative StressIron in your blood can oxidize resulting in damage to your cells and tissues. The increase in oxidative stress is most dangerous to your cardiovascular system.
According to a study published by the American Medical Association, giving blood every six months led to fewer heart attacks and strokes in test participants ages 43 to 61. Excessive iron is thought to contribute to heart disease, especially at its early stages.
Donating blood on a regular basis reduces the iron stores in the body and this study supports the theory that reducing iron appears to preserve cardiovascular health.
A second study of 2,682 men in Finland, reported in the American Journal of Epidemiology, found that men who donated blood at least once a year had an 88 percent lower risk of heart attacks than non-donors. This same group of researchers published a follow-up study and found that men who donated blood were less likely than non-donors to show any signs of cardiovascular disease.1
Donating Blood Protects Against Developing CancerGive blood to help lower your risk of cancer. According to the Miller-Keystone Blood Center, consistent blood donation is associated with lowered risks for cancers including liver, lung, colon, stomach and throat cancers.2
Risk levels dropped in correlation with how often participants donated blood. The association between lower cancer risk and donating blood might also stem from reducing oxidative stress. Free radical compounds can damage your DNA. Damaged genetic material is the hallmark of all cancers.
Donating Blood Gets You a Free Blood AnalysisAfter donating, your blood will be tested for syphilis, HIV (the virus that causes AIDS), hepatitis and other factors. The center will notify you if tests show you may be unhealthy. Your blood will not be used if it could make someone sick.
