Every two seconds someone in the world needs blood. One whole blood donation, which takes about 40 minutes to 1 hour, can save as many as 3 patients. If you think about rolling up your sleeve and save somebody's life, here are some reasons why it can be beneficial for you as well:
- Preserve cardiovascular health
Blood viscosity is one of the main risk factors for developing of cardiovascular disease. If you donate blood regularly, you can eliminate iron that may oxidize in your blood and diminish your blood viscosity.
Blood donation can also decrease the risks of strokes and heart attacks. A medical study showed that participants aged 42 to 60 years old had fewer strokes and heart attacks when they donated blood every 6 months. It was proved that removing oxidative iron from the body through blood donations results in lower iron oxidation as well as reduced cardiovascular diseases.
- Reduce the risk of cancer
Researchers found out that reduction of iron in the body during a blood donation can significantly lower the risk of cancer. A study published in the Journal of the National Cancer Institute showed that iron in the human body can increase free radical damage and lead to an increased risk of aging and cancer. 1,200 people were divided into 2 groups and followed by researches within 4 years. The first group diminished their iron stores by giving blood 2 times per year, while the other group didn't make any changes. The results of the experiment showed that the first group with blood donors had decreased amounts of iron and lower risks of cancer and mortality. Actually, regular blood donations decrease the risks cancer development, including colon, liver, throat and lung cancers.
- Burn calories
It's been calculated that people who donate blood burn about 650 calories per giving 1 pint of blood. Although doctors don't recommend you to make blood donation to be a part of weight loss plan. In order to donate blood you should weigh at least 110 pounds and have healthy iron levels in the body.
