More participation is encouraged. Keywords: ['Social welfare', 'Health knowledge'] Main text: The value of life lies in its irreplaceability; the warmth of humanity comes from the helping hands extended during times of crisis. Among the many ways to protect life and spread kindness, voluntary blood donation connects unfamiliar souls in the most direct and pure form, supporting those whose lives hang by a thread. The fifth principle of the 2024 edition of '66 Guidelines for the Health Literacy of Chinese Citizens' clearly advocates: voluntary blood donation benefits both others and oneself. This short phrase not only promotes social morality but also summarizes a scientific fact, making it a civilized act that every healthy citizen can easily practice.

Many people have misconceptions about blood donation. Some worry that it will harm their vitality or health, while others feel it has nothing to do with them, only realizing the value and scarcity of blood when someone close to them requires it. In fact, blood donation does not damage health; rather, under scientifically regulated procedures, it has a positive regulatory effect on the body. Additionally, it provides a life-saving guarantee for oneself and one's family, achieving a true sense of "helping others while benefiting oneself." Blood is the "river of life" that sustains the functioning of every organism. Red blood cells transport oxygen, platelets are responsible for clotting, white blood cells guard against pathogens, and plasma carries nutrients. In situations such as emergency surgeries, postpartum hemorrhages, severe injuries, treatments for blood diseases, and cancer chemotherapy, blood is an indispensable resource that no medication can replace. In our country, the annual demand for blood in clinical settings is immense, particularly for rare blood types and special components like platelets, which are often in short supply. Each bag of blood can save a life in an emergency room and protect the integrity of a family in a hospital ward. Your willingness to donate could allow a mother to return to her child, help an elderly person enjoy their later years, or enable a young individual to reclaim their place in life. This act of giving, which transcends distances and looks beyond names, embodies the warmest mutual aid among humanity and is a vivid manifestation of social civilization.

For a long time, there have been various misconceptions circulating about blood donation, such as 'donating blood will harm your energy and blood,' 'donating blood will make you weak,' and 'donating blood can transmit diseases.' These claims actually lack scientific basis. According to national regulations, the amount of voluntary blood donation is 200 milliliters or 400 milliliters, which accounts for only 5% to 10% of the body's total blood volume. A healthy adult's total blood volume is approximately 4,000 to 5,000 milliliters, and the body possesses strong compensatory and regenerative abilities. The fluids and inorganic salts lost after donation can be replenished within a few hours, plasma proteins are typically restored within one to two days, and red blood cells and platelets will return to normal levels within one to two weeks. Proper blood donation will not lead to a deficiency in energy or blood, nor will it affect normal life, work, or exercise.

At the same time, the blood donation process has extremely stringent safety guarantees. All blood collection equipment is made of disposable sterile materials, which are destroyed immediately after use, completely eliminating the risk of cross-infection. Before donating blood, medical staff will conduct several rapid tests on the donor’s body temperature, blood pressure, hemoglobin levels, and transaminases, ensuring that only completely healthy individuals who meet the criteria can participate in blood donation. This not only protects the recipients but also shows responsibility towards the donors.

From a health perspective, voluntary blood donation has a truly positive effect on the body. Regular and moderate blood donation can stimulate the bone marrow's hematopoietic function, keeping the marrow's cell generation active and delaying the aging of hematopoietic abilities. Donating blood can reduce blood viscosity, promote circulation, and decrease the risk of high lipid levels, hypertension, and cardiovascular diseases. After donating blood, the body automatically replenishes blood components, making metabolism more active and providing a clearer mind and more energy. It can be said that scientific blood donation is a low-cost, high-return 'health maintenance method' that serves as a dual gift for oneself and for others.

Moreover, the self-interest protection provided by voluntary blood donation acts as an invisible life insurance. According to the national policy on voluntary blood donation, donors and their spouses, as well as direct relatives, can enjoy benefits such as reduced costs and priority access to blood when it is needed for clinical use. By reaching a certain volume of blood donations, one can also benefit from unlimited free blood usage for life. This means that the kindness you offer today may become a solid barrier protecting you and your family on some future day. Regularly donating a bag of blood increases your chances of survival in times of crisis. This mutual assistance mechanism creates a closed loop of generosity, allowing kindness to resonate.

The rewards of donating blood extend far beyond physical health; they encompass psychological satisfaction and a sense of happiness as well. When you sit in the donation chair, watching your warm blood flow slowly into the bag, you can't help but feel a sense of being needed and trusted, a feeling of value. This experience of helping others and saving lives can effectively relieve stress, improve emotions, and enhance one's sense of happiness, encouraging a greater love for life and appreciation for it. Modern psychological research has long confirmed that those who regularly engage in charitable activities and enjoy helping others tend to have a more positive mindset, more stable emotions, and stronger immunity. Voluntary blood donation is not only about assisting others but also about self-help; it is both a contribution and a journey of self-healing.

Of course, voluntary blood donation is not something everyone can participate in; there are clear and scientific health requirements. Donors must be between 18 and 55 years old, in good health, and free from infectious diseases, serious chronic illnesses, malignant anemia, and other such conditions. They should not have undergone major surgery, experienced severe colds, or engaged in excessive drinking in the short term. Prior to donating blood, one should maintain a light diet, get enough sleep, avoid fasting, and refrain from alcohol. After donating, it's important to rest adequately, drink plenty of water, and avoid intense exercise, which will help the body recover quickly and smoothly. These simple precautions not only ensure the safety of the donation but also help keep the body in a comfortable state.

In this fast-paced era, we are always searching for ways to express kindness and protect health, yet we often overlook the simplest and most direct path that is right around us. Voluntary blood donation does not require money or special skills; it only requires a willing heart and a healthy body to complete a life-saving relay. It is a symbol of a civilized society, a manifestation of civic quality, and the most beautiful bridge connecting health and kindness.

A healthy body allows us to help others; selfless dedication gives our lives more significance. Voluntary blood donation is a sign of reverence for life, a responsibility towards society, and a protection for ourselves and our families. It allows blood to convey warmth, lets kindness traverse through crowds, and promotes a mutual exchange of health and compassion.

May more people let go of their concerns and approach the blood donation vehicle, using a bag of warm blood to illuminate lives, and with a single act of kindness to safeguard hope. While helping others, we can gain health; through the act of giving, we find peace of mind. Let voluntary blood donation become a habit, making life more resilient through mutual support, and warming society with love.
