Quantitative Self

Meaning

A philosophy and practice centered on rigorously measuring, tracking, and analyzing one’s own biological, physiological, and behavioral data to gain deep, actionable insights into personal health and performance. This involves the systematic collection of metrics, ranging from continuous glucose monitoring and sleep quality to hormonal assays and genetic data, enabling a data-driven approach to self-optimization. The goal is to move beyond subjective feelings to make precise, evidence-based decisions about health interventions.
