Pulsetto, Truvaga & Nurosym Vagus Nerve Stimulation (VNS) Daily Logbook & HRV Tracker

Why 80% of Vagus Nerve Stimulation Users Plateau After Week 2

Non-invasive cervical and auricular Vagus Nerve Stimulation (VNS) devices like Pulsetto, Truvaga, and Nurosym shift your autonomic nervous system from sympathetic fight-or-flight into parasympathetic rest-and-digest. However, your vagal tone responds differently depending on session timing (morning cortisol peak vs. pre-sleep wind-down), stimulation intensity level, and respiratory cadence.

The 4 Metrics You Must Log Every VNS Session

• Pre-Session State & Subjective Stress Score (1–10): Establish your baseline before placing the device on your neck or tragus.
• Device Intensity Level & Program Mode: Track whether Stress, Anxiety, Sleep, or Burnout settings produce the strongest parasympathetic rebound.
• Paired 4-Second Inhale / 8-Second Exhale Somatic Cadence: Combining electrical VNS with extended exhalations multiplies heart rate variability (HRV) gains.
• Post-Session HRV (ms), Resting Heart Rate (bpm), and Deep Sleep Duration: Identify the exact protocol that maximizes your overnight recovery.
