Blood donors are individuals who voluntarily give their blood to help others in need. This blood is often used in medical treatments, surgeries, and emergencies. Donating blood is a safe process that typically takes about an hour, including registration, donation, and recovery time. The donated blood is tested and processed before being distributed to hospitals and clinics. Blood donations are crucial for patients with conditions like anemia, those undergoing cancer treatment, or individuals who have experienced trauma. Regular donations help maintain an adequate blood supply and can save lives in critical situations.
