Highlights
- Sleep quality doubled, from 4/10 to 8/10, with more restorative rest.
- Energy levels increased from 5/10 to 9/10, indicating sustained vitality.
- HRV (SDNN) rose by 53%, showing improved autonomic balance and recovery.
- No adverse effects were reported, and the participant noted greater mood stability and stress resilience.
Subject Information
-
Age: 50
-
Sex: Male
-
Occupation: Office-based professional
-
Health Status: Generally healthy; reports mild fatigue, unrefreshing sleep, and low daily energy.
-
Baseline Lifestyle: Sedentary work, moderate exercise (2x/week), no significant comorbidities, not on any medication.
Intervention
-
Device Used: NanoVi® Pro device
-
Duration: 20 consecutive days
-
Session Protocol: 1 session per day, 20 minutes per session
-
Delivery Method: Humidified air stream inhalation through nasal cannula while seated and relaxed
Outcome Measures
1. Sleep Quality (Self-reported using a 1–10 Likert scale):
-
-
Baseline: 4/10 (frequent awakenings, non-restorative sleep)
-
Post-Intervention: 8/10 (deeper sleep, fewer awakenings, feeling rested upon waking)
-
2. Daily Energy Levels (Self-reported using a 1–10 Likert scale):
-
-
Baseline: 5/10 (afternoon dips, mental fatigue)
-
Post-Intervention: 9/10 (stable energy throughout the day, improved mental clarity)
-
3. Heart Rate Variability – SDNN (assessed via wearable device, 5-minute resting morning reading):
-
-
Baseline SDNN: 32 ms
-
Post-Intervention SDNN: 49 ms
-
Interpretation: A significant improvement in autonomic balance and recovery capacity
-
Subjective Feedback
“After about a week, I started sleeping through the night more consistently. By the end of the second week, I noticed I had more stamina at work and didn’t need my usual afternoon coffee. I also feel more emotionally balanced and resilient to daily stress.”
Adverse Effects
-
None reported
Conclusion
This 20-day case observation suggests that daily 20-minute sessions with NanoVi® may support measurable improvements in sleep quality, energy levels, and HRV (SDNN), indicating a positive impact on recovery, autonomic nervous system balance, and perceived wellness.
