Alcohol is one of the clearest personal recovery experiments.
daygauge can compare drink logs with sleep, HRV, resting heart rate and next-day movement so users see their own pattern, not a lecture.
Start with the signal your own data can support.
Alcohol is a high-intent topic because users often feel the effect before they can explain it.
The premium insight is personal attribution: whether later drinks, higher quantity or drinking close to bedtime coincided with worse sleep or softer recovery.
daygauge can use optional alcohol logs beside sleep duration, sleep timing, resting heart rate, HRV and next-day movement.
What this page covers.
From research context to product evidence.
What a user should expect to see in the app.
Alcohol logged at 21:40; overnight resting HR was 7 bpm above baseline and HRV was 18% lower.
Weekly review previewdaygauge can use optional alcohol logs beside sleep duration, sleep timing, resting heart rate, HRV and next-day movement.
Confidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.
daygauge would suggest one small experiment, then watch whether the evidence repeats over the next week.

Evidence 1
Alcohol logged at 21:40; overnight resting HR was 7 bpm above baseline and HRV was 18% lower.
Evidence 2
Sleep timing: wake-after-sleep proxy rose after late drinking versus alcohol-free baseline nights.
Evidence 3
Next-day evidence: movement spread was compressed into one afternoon window after a late social night.
