Assalam-u-Alaikum!
Hope everyone is doing well. Have you ever considered what kind of benefits you might be getting from donating blood? Well, recent studies have shown that there might be certain physical benefits attached to blood donation.
We all know that our blood contains iron; iron is an important nutrient for your body and for your health. It helps your cells "breathe". Iron works with protein to make the hemoglobin in red blood cells. The hemoglobin carries oxygen to all parts of the body so it can perform its normal functions. The body stores iron in the liver, spleen, and bone marrow. A study was conducted comparing people who donate blood to people who do not. The research entailed in analyzing if having high levels of iron in your blood has anything to do with heart disease. The results were astounding! This should get everyone to donate blood! :-) Check it out...
Mild iron deficiency has been hypothesised to reduce risk of heart disease risk, while a high concentration of body iron has been suggested as a risk factor for myocardial infarction.
In the 24 months before the baseline examinations 153 (5.7%) of the 2682 participants had donated blood. During follow up, one (0.7%) of the donors experienced an acute myocardial infarction compared with 226 (9.8%) of the 2529 non-donors (P<0.001>1) shows that, in a multivariate model adjusted for the main coronary risk factors, the blood donors' risk of acute myocardial infarction was 86% less than that of the non-donors (relative risk 0.14, 95% confidence interval 0.02 to 0.97, P=0.047).
We suggest that the loss of iron associated with giving blood might be the reason for the observed risk reduction. However, voluntary blood donors seem to be generally more health conscious and more healthy than those who do not donate blood, and this may have caused self selection bias. In our study the association between donating blood and reduced risk for myocardial infarction was weakened but remained significant after adjustment for the main coronary risk factors. Our finding needs to be confirmed in other prospective population studies, and investigation of the impact of iron depletion on atherosclerotic progression or coronary events is necessary to test the above theory.
