30-Day WVI Challenge: Average Improvement +18 Points

The Challenge Is Simple

Follow your AI coach's daily recommendations for 30 days straight. No heroics. No expensive supplements. No gym membership required. Just do what the AI says.

The Results (4,000 participants)

  • Average WVI improvement: +18 points (from 56 to 74)
  • Top 10% improved: +28 points
  • Sleep duration increase: +38 minutes average
  • HRV improvement: +12ms average
  • Stress reduction: -23% (measured by ANS balance)

What Changed

The most impactful changes (in order):

  1. Sleep consistency (WVI +6): Same bedtime ±30 minutes, including weekends
  2. Morning light (WVI +3): 10 minutes outside within 1 hour of waking
  3. Daily movement (WVI +4): 30 minutes of any activity (walking counts)
  4. Evening wind-down (WVI +3): No screens 30 min before bed
  5. Breathing practice (WVI +2): 5 minutes of box breathing daily

The Financial Impact

Average WVI 56 → 74 = moving from 5% yield tier to 12% yield tier. At $500 deposit: $25/month → $60/month. The challenge paid $35/month more for the same deposit. For free.
