Title: How Altruistic Blood Donation Improves Your Health and That of Others Profile: Unpaid blood donation benefits both donors and recipients, fostering health and solidarity in society. Keywords: ['Social well-being', 'Health knowledge.'] The life is valuable precisely because it cannot be repeated; the warmth of the world lies in the existence of people willing to extend a hand in times of crisis. Among the many ways to protect life and convey kindness, involuntary blood donation directly connects the souls of individuals who do not know each other, sustaining lives that are on the verge of crisis. The fifth guideline of the 'Compendium on the Health of Chinese Citizens 2024' clearly promotes: donate blood altruistically, help others and benefit oneself. These eight summarized words exalt social morality, compile scientific facts, and represent a civilized act that every healthy citizen can easily practice.

Many people have misunderstandings about blood donation. Some fear it will affect their energy or health, while others believe it does not concern them until someone close to them needs blood, at which point they suddenly realize how valuable and scarce it is. In fact, donating blood not only does not harm health, but under a scientific and regulatory process, it has a positive effect on the body and also provides a guarantee of life for oneself and one's family, thus achieving a true sense of 'helping others and benefiting oneself'.

Blood is the 'river of life' that keeps living beings functioning. Red blood cells transport oxygen, platelets handle coagulation, white blood cells combat pathogens, and plasma carries nutrients. In critical situations such as emergency surgeries, postpartum hemorrhages, severe trauma, hematologic disease treatments, and chemotherapy, blood is an essential resource that no medication can replace. In our country, the amount of blood used in clinics is enormous every year, especially concerning rare blood types and special blood components like platelets, which are often found in critical condition. Each bag of blood has the potential to save a life in the emergency room or protect the unit of a family in the hospital. A simple gesture on your part could enable a mother to reunite with her child, allow an elderly person to enjoy their final years, or help a young person return to their life's stage. This gift of life that transcends distances and does not inquire about names is the warmest expression of mutual assistance among humans and the most vivid manifestation of social civilization.

For a long time, several myths about blood donation have circulated, such as 'donating blood harms qi and blood', 'donating blood weakens', or 'donating blood can spread diseases'. However, these claims have no scientific basis. According to national regulations, the amount of blood that can be donated altruistically is 200 milliliters or 400 milliliters, which represents only 5% to 10% of the total blood volume in the body. The total blood volume in a healthy adult is approximately 4,000 to 5,000 milliliters, and the body has a formidable capacity for compensation and regeneration. The fluids and minerals lost after donation can be restored in a few hours, plasma proteins are replenished in one to two days, and red blood cells and platelets return to normal levels in one to two weeks. A proper blood donation will not cause a deficiency of qi or blood, nor will it affect normal life, work, or exercise.

At the same time, the blood donation process has strict safety guarantees. All materials used for blood extraction are disposable and sterilized, and are destroyed after use, completely eliminating the risk of cross-infections. Before donation, the medical staff will conduct multiple quick tests on the donors, including measuring body temperature, blood pressure, hemoglobin, and transaminases, ensuring that only healthy individuals who meet all physical requirements can participate in the donation. This not only protects blood recipients but is also an act of responsibility towards donors.

From a health perspective, donating blood altruistically has genuinely positive effects on the body. Regularly donating blood in adequate amounts can stimulate the hematopoietic function of the bone marrow, maintaining its vigor in cellular production and delaying the aging of hematopoietic functions. Blood donation also reduces blood viscosity, promotes circulation, and decreases the risk of diseases such as hyperlipidemia, hypertension, and cardiovascular and cerebrovascular diseases. After donating, the body automatically updates blood components, activating metabolism and providing greater vitality and energy. It can be said that scientifically donating blood is a form of 'low-cost, high-return health maintenance', which serves as a double gift for both oneself and others.

Most importantly, unpaid blood donation offers a selfish protection, akin to an invisible life insurance. According to the national policy of voluntary blood donation, donors and their spouses, as well as their direct relatives, can enjoy benefits such as cost reductions and priority in using blood when they require it. If the amount of blood donated reaches certain standards, they will also have access to unlimited free blood for life. This means that the act of generosity you perform today could become a solid shield protecting you and your family in the future. Donating a bag of blood in normal times can mean a lifeline in difficult situations. This mechanism of mutual assistance creates a cycle of generosity, allowing kindness to resonate.

Blood donation brings benefits that go beyond physical health; it also offers psychological satisfaction and happiness. When you sit in the extraction chair, watching warm blood flow slowly into the bag, a sense of value arises within you as you feel needed and reliable. This experience of helping others and saving lives can effectively relieve stress, improve mood, and increase the sense of well-being, encouraging people to love life more and cherish their existence. Modern psychological studies have shown that those who regularly engage in altruistic activities and enjoy helping others tend to have a more positive mindset, more stable emotions, and a stronger immune system. Voluntary blood donation is not only an act of assistance to others but also of self-confidence; it is both a process of giving and a journey of self-healing.

Of course, donating blood is not something that just anyone can participate in, as there are clear and scientific health requirements: being between 18 and 55 years old, being in good health, and not having infectious diseases, serious chronic diseases, malignant anemia, among other problems. Additionally, in the short term, one should not have undergone major surgeries, suffered severe colds, experienced sleeplessness, or engaged in excessive alcohol consumption. It is recommended to maintain a light diet, get enough sleep, not fast or consume alcohol before donation. After donation, it is important to rest adequately, drink plenty of water, and avoid intense exercises, which will allow the body to recover quickly and steadily. These simple recommendations ensure the safety of the donation and help the body remain in a comfortable state.

In this fast-paced era, we are always looking for ways to express kindness and care for our health, but we often overlook the simplest and most direct path around us. Donating blood requires no money, nor special skills; it only takes a willing heart to contribute and a healthy body to complete a relay of life. It symbolizes civilization, manifests civic education, and is also the most beautiful bridge connecting health with kindness.

A healthy body gives us the ability to help others; selfless giving adds greater meaning to our lives. Altruistic blood donation is an act of respect for life, a commitment to society, and a method of protecting oneself and family. It allows blood to convey warmth, kindness to cross between people, and health and love to meet reciprocally.

I hope more people set aside their concerns and approach blood donation vehicles, using a bag of warm blood to illuminate lives and protect hope with an act of kindness. By helping others, one can also gain health; in the process of giving, peace of mind is obtained. May blood donation become a life habit, may life become more resilient through mutual assistance, and may society become warmer through solidarity.
