  • Blood donation may lower the risk of heart disease and heart attack. This is because it reduces the blood's viscosity. A study proved that regular blood donors have significantly lower total cholesterol and low-density lipoprotein levels as compared to non-donors.
  • It reduced the iron levels of the body. High blood iron can cause a variety of symptoms, such as irregular heartbeats, lethargy, muscle weakness, hardening of arteries, accelerated cholesterol oxidation, decreased libido etc. When blood is donated, 225 to 250 mg of iron is removed from the body.
