biological aging

Biological aging refers to the gradual changes in the body’s cells, tissues, and organs over time that reduce their function and resilience. It results from complex processes like accumulated cellular damage, genetic activity shifts, and decreased ability to repair. These changes can lead to slower healing, weaker immune responses, and increased vulnerability to diseases. Unlike chronological age, which is simply counting years, biological aging reflects how well or poorly the body is functioning, and it varies between individuals based on genetics, lifestyle, and environmental factors.
