The inquiry

What rhythms can wearable signals reveal without claiming more certainty than the data supports?

Story

An investigation of HRV, sleep, stress, temperature, recovery, and cyclical patterns across daily and longer time scales. The work is presented here as part of a living system rather than as an isolated product: its meaning comes from the people, practices, and neighboring works that make it useful.

The research question was connected to Ring, menopause temperature patterns, family observation, and calm visual interfaces.

Define measurable hypotheses, collect consented longitudinal data, record confounders, and separate observation from diagnosis.
