Let the data serve you—not stress you.

Summary: Wearables shine when they make tiny next steps obvious. Track HRV, resting heart rate, sleep efficiency, and night temperature to shape bedtime, training, and recovery—without chasing perfection.

Key metrics in plain English

HRV (heart rate variability)

• Useful as a trend (7–30 days), not a one-day judgment.
• Dips with late light, alcohol, poor sleep, illness, heavy stress.
• Rises with cooler nights, consistent sleep window, Zone-2, recovery days.

RHR, Sleep, Night temperature

• RHR: Lower at rest over time = fitness/recovery signal.
• Sleep efficiency: Less time awake in bed is realistic.
• Night temp trend: Spots late meals, alcohol, room warm-ups.

Trends > snapshots. Look for gentle movement over weeks.

Device fit matrix (rings · watches · bands)

Form factor	Strengths	Trade-offs	Good for
Ring	Comfort at night; solid temp/HRV-like signals	No screen; workouts estimated from movement	Sleep focus, minimalism
Watch	Workout accuracy; on-wrist cues; GPS options	Charging cadence; may feel bulky in bed	Training + daily readiness
Band	Lightweight; all-day wear	Mixed accuracy between models	Step/move nudges, basics

Quick wins this week

Under 10 minutes

• Set a consistent sleep window (±30 min) for 7 days.
• Move dinner/alcohol earlier 2–3 hours before bed.
• Use Night Shift on screens at sunset; dim lamps.

Training choices

• Low-readiness day: Zone-2 walk/ruck + mobility.
• High-readiness day: strength lower body (glutes/hips/back).
• Track energy (0–10) beside readiness score.

Pair data with how you feel. Let both guide today’s plan.

Privacy & consent (small but mighty)

• Decide what to collect and who sees it. Turn off exports you don’t need.
• Review sharing defaults + location permissions in each app.
• Use private tags (e.g., “ALCOHOL”, “LATE-DINNER”) to explain spikes without oversharing.

Your 2-week plan (calibrate → personalize)

Week 1 — Calibrate

• Steady routines: bed/wake, caffeine, training times.
• Log 3 KPIs daily: energy, sleep quality, readiness (0–10).
• Add two tags you’ll use: “ALCOHOL”, “LATE-DINNER”.

Week 2 — Personalize

• Low readiness: reduce intensity, keep movement.
• High readiness: progress strength (lower body), earlier dinner.
• Pick one sleep lever: cooler room, darker, earlier screens-off.

Troubleshooting (don’t panic at dips)

What you see	Likely reason	Try this
HRV dip + higher RHR	Late light, alcohol, heavy training, illness	Cooler room, earlier dinner, Zone-2 day
Sleep efficiency low	Inconsistent window, screens late	Wind-down alarm, dim lamps
Readiness bounces	New device or still calibrating	Give it 7–14 days; review trend weekly

Self-check: Where to focus

How to use this: Question 1–10 cover habits/patterns; O/X checks basics. Your score suggests a starting tier. Saved locally only.

0 = Often/yes (or 0–1 day/week) 1 = Sometimes (2–3 days/week) 2 = Rarely/no (4–7 days/week)

Your answers stay on this device only (localStorage).

Patterns & habits

Question 1

I stay up with bright screens until bed most nights. Some nights. Rarely—lights are dim.

Question 2

Dinner or alcohol is often within 2 hours of bedtime. Sometimes. Usually earlier.

Question 3

My sleep window varies by >90 minutes across the week. ~60 minutes. ±30 minutes.

Question 4

I ignore low-readiness signals and still push hard workouts. Sometimes. I adjust training.

Question 5

I rarely take low-intensity recovery days. Sometimes. Weekly at least.

Question 6

I don’t log simple tags (e.g., ALCOHOL, LATE-DINNER). Occasionally. I tag consistently.

Question 7

Breakfast seldom anchors with ~30g protein. Some days. Most days.

Question 8

I never correlate how I feel with readiness/sleep data. Sometimes. I check both.

Question 9

I change many variables at once (hard to learn what works). Sometimes. One lever at a time.

Question 10

I don’t review weekly trends; I react to single days. Sometimes. I review weekly.

Quick O/X

O: HRV is most useful as a 7–30 day trend, not a single number. X O: Late meals, alcohol, and warm rooms can lower next-morning readiness. X O: Pair data with how you feel before changing your plan. X
