The Advantages of Giving Blood Donations
Donating blood is a simple yet impactful act that can save up to three lives. This practice, which has been a part of medical history for over a century, continues to be a vital service in the United States, where someone needs blood every two seconds.
The process of donating blood is straightforward and safe for healthy adults. Before your appointment, it's recommended to drink an extra 16 ounces of water, eat a healthy meal that's low in fat, wear a short-sleeved shirt or one with easy-to-roll-up sleeves, and inform the staff of your preferred arm or vein and whether you prefer to sit up or lie down.
Upon arrival, you'll need to register and provide identification, followed by a quick physical examination. A health screening is required before donation, which includes checks on pulse, blood pressure, body temperature, and hemoglobin levels.
For a whole blood donation, you'll be seated in a reclining chair. A small area of your arm will be cleaned, a sterile needle will be inserted, and a pint of blood will be drawn in 8 to 10 minutes. After donation, you'll be given a snack and a drink and be able to sit and rest for 10 or 15 minutes before leaving.
Other types of donations, such as platelet donation, plasma donation, and double red cell donation, are performed using a process called apheresis. In apheresis, an apheresis machine is connected to both arms, collects a small amount of blood, separates the components, and returns the unused components back to you.
Donating blood not only saves lives but also offers benefits for emotional and physical health. Helping others can reduce stress, improve emotional well-being, benefit physical health, help get rid of negative feelings, and provide a sense of belonging and reduce isolation.
Moreover, blood donation provides a free mini-physical that can offer insight into one's health and detect underlying medical conditions or risk factors for certain diseases. Blood donated is tested for various diseases, including hepatitis B, hepatitis C, HIV, West Nile virus, syphilis, and Trypanosoma cruzi.
It's important to note that blood donation is safe for healthy adults and carries no risk of contracting disease, as new, sterile equipment is used for each donor. However, research on whether blood donation lowers the risk of heart disease is mixed. Some studies suggest it may increase the risk due to unfavorable cholesterol levels, while others suggest it may reduce the risk by lowering iron stores.
To be eligible to donate, you must be 17 or older (with some states allowing donation at 16 with parental consent), weigh at least 110 pounds, and be in good health. You'll also need to provide information about medical conditions and any medications you're taking, as these may affect your eligibility to donate.
The first blood donation stations in the USA were set up primarily in major cities such as New York and Chicago during the early 20th century, often associated with hospitals and military hospitals as blood transfusion practices developed.
In conclusion, donating blood is a straightforward and rewarding process that offers numerous benefits, both for those in need and for the donor themselves. If you're considering donating, remember to stay hydrated, eat a healthy meal, and be prepared to provide your medical history. Your donation could save a life.
