* A decision to donate blood can save a life, or even several lives, if the blood is separated into its components – red cells, platelets and plasma – which can be used individually for patients with specific conditions.

* However, blood donation can also come with its own set of benefits for donors. Blood donation can help reduce excess iron levels in the blood thereby preventing hemochromatosis, a condition which can increase risk of cardiovascular diseases including heart attack and stroke.

* This can help with early detection of certain health conditions, such as anaemia or infectious diseases, which may otherwise go unnoticed.
