At what age can one donate blood?

Generally, individuals between the ages of 18 and 55 are eligible to donate blood. Blood donation should be conducted at a正规 hospital. Detailed explanations are as follows:

Minors under the age of 18 are still in a stage of physical growth and development, and their organ functions are not yet fully mature. Blood donation may affect normal physical development and physiological functions. Middle-aged and elderly individuals over 55 years old experience gradual decline in body functions and may have certain health risks, such as cardiovascular diseases or chronic illnesses. Blood donation could increase physical strain and be detrimental to their health. Healthy individuals aged between 18 and 55 have relatively stable bodily functions and vigorous bone marrow hematopoietic activity. They can recover blood volume and blood cell counts relatively quickly after donating blood, without significant adverse effects on their health. At the same time, blood donation can stimulate bone marrow hematopoiesis and promote metabolism, which is beneficial to overall health.

However, prior to donating blood, other requirements such as weight and health status must also be met. For example, adult males must weigh no less than 50 kilograms, and adult females no less than 45 kilograms. Additionally, donors should be free from infectious diseases, chronic illnesses, and other health conditions.
