Wrist temperature in perimenopause
Overnight skin-temperature deviation from your personal baseline — the signal your watch quietly collects while you sleep. Skin temperature, not core; deviation, not degrees-absolute.

Why it matters in the transition
Body temperature rhythms track the menstrual cycle (the old basal-thermometer trick, automated), and vasomotor nights can leave temperature signatures. As cycles turn erratic, the temperature rhythm's behavior is itself informative context.
How Perity uses it
Nightly deviations sync to your record and sit alongside night-sweat entries and cycle phase. Perity treats meaningful shifts against your baseline as context for what you logged — never as a diagnosis or a fertility verdict.
The honest caveats
Room temperature, alcohol, illness, and blanket politics all move wrist temperature. It's a rhythm signal, useful in aggregate against your own baseline — not a thermometer reading to react to.
Symptoms it gives context to
