The first theory is that blood donors must be considered “healthy” before they roll up their sleeve, so they are less likely to suffer heart disease because they are already in good health and probably have lower blood pressure and cholesterol levels that non-blood donors.
The second theory is that iron has a significant impact on atherosclerosis, or hardening of the arteries. When you give blood you are removing 225 to 250 milligrams of iron from your system, thus cutting your risk of heart disease.
Pre-menopausal women tend to have half of the amount of iron as men because they lose iron every month through menstruation. Coincidentally, they also suffer half as many heart attacks.
However, once a woman goes through menopause her risk of heart attack increases, but donating blood can reduce that risk.
In addition to depleting iron levels, when you donate blood we give you a free mini-physical and let you know your blood pressure as well as you cholesterol levels-two major risk factors when it comes to heart disease.
While scientists are researching why donating blood reduces the risk of heart attack, one thing is clear-donating blood has many benefits to the donor as well as the recipient. So, if you want to pick up a healthy habit, head over to your local blood center and give the gift of life.
Plus, when donors give blood they receive a cholesterol test and a mini-physical that can catch certain illnesses in the early stages. Florida’s Blood Centers tests blood from donors for numerous diseases including HIV 1 and 2, West Nile Virus, Syphilis, Hepatitis B, Hepatitis C, T. Cruzi or Chagas as well as the Human T-Cell Lymphotropic Virus 1 and 2.
