Voluntary blood donation plays a crucial role in public health by ensuring a stable supply of blood and its components, essential for medical treatments including surgeries, trauma care, and chronic disease management. Voluntary donors, often healthier individuals, enhance the safety of the blood supply and play a vital role in emergency preparedness. Beyond its societal benefits, regular blood donation may offer health advantages for donors, including improved cardiovascular health due to reduced iron levels and psychological benefits stemming from altruism and a sense of social responsibility. Public health initiatives are instrumental in fostering blood donation through education, awareness campaigns, and targeted donor recruitment strategies. These efforts encourage a culture of social responsibility, inspiring community participation and improving overall healthcare system sustainability. Despite these efforts, challenges such as fluctuating donation rates, aging populations, and shifting demographics underscore the need for ongoing initiatives to ensure a sufficient blood supply. As a public health priority, voluntary blood donation demands continuous promotion and innovation to meet the growing demand for blood products and maintain healthcare system resilience. This review highlights the public health significance of voluntary blood donation, with particular focus on its benefits for donors and its role in supporting healthcare systems.
