On June 14, 2023, the global community comes together to celebrate World Blood Donor Day.
So, how frequently does a person donate blood? Dr. C Shivaram, a transfusion medicine specialist at Manipal Hospital, explains that an individual typically donates this life-saving liquid three to four times a year.
So, which has a higher benefit - donating blood or engaging in brisk walking? Dr. Shivaram illustrates that a lengthy walk or treadmill exercise for half an hour daily can burn around 150 calories. Performing these activities four times within a week burns approximately 600 calories, almost equivalent to the 650 calories burned per unit of blood donated.
Indeed, a week's worth of exercise is roughly equivalent to donating blood once, as per Dr. Shivaram's statement pointing to research conducted at the University of California, San Diego.
But how does donating blood benefit human beings? Blood donations can help in treating a variety of severe health conditions, including different forms of cancer, significant accident injuries, blood-related genetic issues, and transplant patients.
Various doctors present their perspectives on the topic. According to Dr. Aniket Mule, an internal medicine consultant, blood donation should be a frequent activity. Each donation utilizes new equipment to minimize infection risk.
Dr. Mule adds that donating blood can help manage health risks, control blood pressure, maintain body iron levels, and regulate hemoglobin.
According to Dr. Shivaram's research, habitual donors are safeguarded from heart disorders due to their lower bad cholesterol (LDL) and triglyceride levels, as compared to occasional or non-donors.
Dr. Shivaram also notes that while one-time donors can donate blood up to the age of 60, the age limit extends to 65 for regular donors. Regular platelet donations, twice a month, can help control lipid levels, thus countering the plasma lipids associated with platelets.
As Dr. Geetha N Gowdar, a senior consultant in Bangalore, emphasizes, these parameters are thoroughly examined and corrected if needed.
The body's bone marrow compensates for the donated blood by producing new cells, making the individual feel more energetic. Therefore, maintaining a regular blood donation schedule can contribute to a healthier, longer life and offer critical support to those in need.
Post-donation, it is recommended to follow specific precautions. Consuming a healthy, nutrient-rich diet and ensuring proper rest helps regain energy. Hydration is also key. As Dr. Sunuta Kapoor, a pathologist at Scan Clinic, advises, it is crucial to maintain a nutritious diet post-donation, avoid strenuous activities like weight lifting, and drink ample fluids to rejuvenate your energy.
