What is the Origin of Biological Friction?

The term is an evocative concept developed within the functional and longevity medicine communities to describe the energetic cost of maintaining homeostasis in a suboptimal state. It draws on thermodynamics and systems biology, where energy expenditure increases to overcome resistance in biological pathways. It serves as a simple, powerful descriptor for the complex process of biological decline.

What is the Mechanism of Biological Friction?

Biological friction is driven by several underlying factors, including mitochondrial dysfunction, telomere shortening, and the accumulation of senescent cells that secrete pro-inflammatory cytokines. Hormonal imbalance, such as cortisol dysregulation or thyroid insufficiency, significantly contributes by increasing systemic stress and impairing cellular repair cycles. Reducing this friction requires targeted interventions that restore cellular efficiency and optimize endocrine signaling pathways.

Biological Friction

Meaning

A clinical metaphor representing the cumulative, systemic resistance and inefficiency within an organism’s physiological processes, often escalating with chronological age and chronic stress. This friction manifests as reduced metabolic efficiency, increased inflammatory load, and impaired cellular communication. It is a measurable state of sub-optimal function that precedes overt pathology, diminishing overall vitality and resilience.
