Blood donation saves thousands of lives daily across the globe. According to the American Red Cross, someone needs blood every two seconds. Since blood components have a short shelf life, maintaining a steady supply is a constant challenge; this is why voluntary donation is so vital. A healthy individual can donate blood 3 to 4 times a year. The amount of blood drawn is approximately 400 ml, which has no negative impact on the donor's health.

Blood donation is effective in reducing blood pressure, heart rate, high glucose levels, and blood lipids. Before the procedure, donors are screened and asked specific questions to ensure that the process is safe for them. Additionally, the donated blood is tested to guarantee it is safe for patient use.
