stressnumbers

Stressnumbers is a term used to describe numerical indicators intended to quantify stress intensity or burden. They are not a single universal measure; rather, they describe a class of composite scores derived from physiological data, self-report, and contextual information. The goal is to enable comparison across individuals, time, or situations.

A typical stressnumber combines signals such as heart rate variability, skin conductance, respiration rate, hormonal markers, and subjective ratings of stress. Data are collected over a defined window, normalized, and weighted to produce a single score or a small set of scores. Some frameworks use percentiles within a reference population, while others employ standardized z-scores to situate a value relative to norms.

Applications of stressnumbers span several fields. In occupational health, they can help identify high-burden periods and assess interventions. In sports science, they may track recovery and readiness. In clinical settings, they can aid in monitoring anxiety or burnout, while in human-computer interaction they may inform adaptive interfaces or workload management.

Limitations include the lack of standardization, which leads to different systems producing different scales and limits cross-study comparability. Physiological signals vary with individual differences, environmental factors, and measurement methods. Privacy, consent, and the potential for over-reliance on numeric scores at the expense of qualitative context are important considerations.
