Waking up tired
You slept, but you still do not feel restored.
Improve your HRV through better recovery
Build a more consistent recovery routine with gentle, ear-based taVNS. Use Luna Plus with the ZenoWell App to track HRV, sleep, and how your body responds over time.

WHEN REST DOES NOT FEEL LIKE RECOVERY
Still tired after a full night's sleep?
Time in bed does not always mean full recovery. Daily strain, disrupted sleep, and physical load can affect how restored you feel and may also influence your HRV trend.
Running out of energy
Your energy drops before the day is over.
Recovering more slowly
It takes longer to feel ready after exercise.
UNDERSTAND YOUR SIGNAL
Your HRV trend can reveal changes in recovery
HRV reflects the variation in time between heartbeats.
Your number can change with sleep, training, illness, alcohol, travel, and daily strain.
What matters most is how your readings compare with your own baseline over time.
App screens are illustrative. Readings and individual responses vary.
WHY HRV CHANGES
Better recovery starts with a repeatable routine
A single HRV reading rarely tells the whole story. Follow the same routine, measure under similar conditions, and review your trend across several weeks.
Personal baseline
Support your daily recovery Follow your response
Luna Plus connects body signals, guided taVNS sessions, and daily patterns to help make recovery more consistent over time.
A simple 20-minute routine
Use the same simple process each day to understand your state, choose a reset, and follow your response over time.
Check your recent trend
Review your recent HRV and sleep pattern.
Use Luna Plus for 20 minutes
Choose a routine that fits your day.
Review your response
Notice how you feel and how the trend changes.
HRV AND AUTONOMIC SCIENCE
What the science says about HRV and taVNS
HRV can provide useful information about recovery when measured consistently and interpreted in context. Research has also explored how taVNS may affect autonomic measures, but individual results vary.
HRV is a personal trend
Your own baseline is more useful than a universal target.
Daily strain can shift HRV
Review several days together and compare your trend with sleep, activity, and how you feel.
taVNS research is still developing
Studies have reported mixed results, so a specific HRV change cannot be guaranteed.

Start your recovery routine
FAQ
What people ask before starting
Start with consistency rather than a single hack. Measure under similar conditions and watch your trend over several weeks.
Regular sleep, less alcohol, steady aerobic activity, enough recovery after hard training, and stress management can all support a healthier pattern. Luna Plus can be part of that routine, but it should not replace the basics.
There is no single “good” HRV number for everyone. Age, fitness, health, genetics, and the way your device measures HRV can all affect the result.
Use the same device and compare your readings with your own baseline. A stable personal trend is more useful than comparing your score with someone else's.
Sleep is only one part of recovery. A hard workout, mental stress, alcohol, travel, illness, dehydration, a late meal, or normal measurement variation may affect your HRV.
One low night is not enough to draw a conclusion. Look at the pattern across several days and consider how you feel.
Sometimes. Fatigue and lower-than-usual HRV can both appear when your body is under more strain or has not fully recovered.
Fatigue has many possible causes, so HRV cannot diagnose why you feel tired. Persistent, severe, or unexplained fatigue should be discussed with a healthcare professional.
Not always. A gradual improvement in your personal average may be a positive sign, but a single unusually high reading does not automatically mean you are fully recovered.
Measurement errors and short-term physiological changes can also cause spikes. Read the number alongside your sleep, resting heart rate, training load, and how you feel.
Devices may measure HRV at different times, use different sensors, or calculate different HRV metrics. Even two devices worn on the same night may show different numbers.
Avoid comparing values across platforms. Choose one device and follow its trend under similar conditions.
Some studies have reported changes in HRV measures after transcutaneous auricular vagus nerve stimulation. Other studies found smaller or no clear changes.
Results vary by stimulation settings, study design, baseline autonomic function, and the way HRV is measured. Luna Plus is designed to support a consistent recovery routine, not to guarantee a specific HRV number.
Give yourself enough time to establish a baseline first. A few days can be noisy, so look at a rolling trend over at least two to four weeks.
Some users notice a calmer feeling before they see a clear HRV change. Others may not see a meaningful change in HRV at all. Both experiences are possible.
Luna Plus combines guided, ear-based taVNS with body-signal tracking and AI guidance to help you build a more consistent recovery routine.
Use the ZenoWell App and Zenoband Mobi, or another supported data source, to review HRV and sleep trends alongside your Luna Plus sessions. Luna Plus is designed to support your routine and help you understand your response over time. It does not guarantee a specific HRV increase.
