Physiological Buffering

Meaning

Physiological Buffering is the inherent, complex capacity of the body’s homeostatic mechanisms to resist and minimize sudden or significant fluctuations in critical internal variables, such as blood pH, core temperature, blood glucose, or circulating hormone concentrations. This biological resilience is mediated by a highly integrated network of organ systems, ensuring that acute stressors or environmental changes do not lead to catastrophic systemic failure. Robust buffering capacity is a primary characteristic of youthful health, adaptive reserve, and overall vitality.
