Quantified Self

Meaning

The Quantified Self is a personal health movement and practice involving the routine collection and rigorous analysis of one’s own physiological, behavioral, and environmental data to gain self-knowledge and optimize personal well-being. This discipline utilizes various technologies, including wearable sensors, continuous glucose monitors, and detailed symptom logging, to generate high-resolution, personalized datasets. In hormonal health, this data—such as sleep quality, heart rate variability, and cycle tracking—provides invaluable contextual information that complements traditional laboratory diagnostics. The practice empowers individuals to collaborate more effectively with their clinicians in designing truly personalized interventions.
