Recovery & Sleep
Recovery Is Where Results Happen
HRV recovery intelligence and sleep analysis that connects nutrition to how you feel. Your watch captures the data — JUNA tells you what to do about it.
HRV Intelligence
HRV Recovery Analysis
Heart rate variability is the most reliable window into your autonomic nervous system. NutriJourney transforms raw HRV data into a recovery story — connecting last night's sleep, yesterday's training, and this morning's readiness into one clear picture.
- Nightly recharge score that tells you how recovered you actually are — not just how long you slept
- ANS balance tracking: sympathetic vs parasympathetic activity reveals whether your body is in fight-or-flight or rest-and-recover
- Recovery trends over weeks and months so you can see the real impact of nutrition and lifestyle changes
- Morning readiness that factors in sleep quality, stress load, and cumulative training — not just a single number
Sleep Analysis
Sleep That Tells a Story
Most apps show you a sleep graph and leave you to figure it out. JUNA reads your sleep architecture alongside your nutrition log and finds the connections — late caffeine, heavy meals, alcohol timing — that other apps completely miss.
- Sleep stage breakdown: deep, REM, and light sleep tracked and trended over time
- Sleep quality scoring based on duration, efficiency, latency, and architecture — not just time in bed
- Sleep-nutrition correlation: see exactly how that 8pm espresso or late-night meal showed up in your data
- JUNA identifies patterns across weeks and coaches you toward better sleep — specific, actionable, personal
Training Readiness
Know When to Push and When to Rest
Overtraining doesn't announce itself with a warning sign. It creeps in through accumulated fatigue, poor recovery, and ignored signals. NutriJourney catches it early — before your performance drops and your motivation crashes.
- Cardio load ratio (acute-to-chronic) monitors your training ramp so you push hard without pushing too far
- Skin temperature trends as an early recovery signal — subtle shifts that predict how you will feel tomorrow
- Overtraining detection that flags risk before it becomes injury, illness, or burnout
- Smart rest day recommendations based on your actual recovery data, not a generic weekly schedule
Wake Up Knowing Where You Stand
Every metric connected, every signal interpreted — so every morning starts with clarity.
Nightly Recharge
Wake up knowing if today is a push day or a recovery day. Your recharge score combines HRV, sleep quality, and training load into one clear answer.
Cardio Load Ratio
Prevent overtraining with acute-to-chronic load monitoring. See when your recent training is outpacing your body's ability to adapt and recover.
Recovery Alerts
JUNA warns you when recovery metrics drop and suggests specific adjustments — lighter training, earlier bedtime, or a nutrition tweak that could make the difference.
*Certain features deliver the highest precision when paired with compatible hardware (InBody scanner, Polar wearable, or similar devices).
Without hardware, JUNA estimates these metrics using your nutrition logs, weight trends, and self-reported data — still useful, but less precise. Hardware integrations are optional and enhance accuracy over time.
