Your watch records HRV, resting heart rate, sleep and wrist temperature every night — into your phone, on-device. Here's what each one tells you about whether to push or back off today, how noisy it is, and how long before a trend is real. No signup. No email.
A rough window into how taxed your system was overnight. Very noisy night-to-night — alcohol, late meals, a warm room all move it. Read the 7-day trend vs. your own baseline, never a single morning, never someone else's numbers.
Steadier than HRV. When it creeps up over several mornings, that's often an earlier load signal than HRV alone. Best read alongside HRV, not instead of it.
Duration and consistency are the foundation everything else sits on. The watch estimates stages; treat the trend as directional, not clinical.
A slow-moving baseline signal. Useful as a multi-night trend, meaningless as a one-off reading.
Give any of these ~2–3 weeks before you trust the trend — that's how long it takes to learn your normal.
