Summary

Clean air is free, so we ignore it. Air quality expert Mike Feldstein reveals why the thing we breathe most is the health pillar we optimize least.

Full show notes and resources can be found here: jordanharbinger.com/1246

What We Discuss with Mike Feldstein:

  • L.A. wildfires created unprecedented contamination that lingered for weeks. 15,000+ homes and cars (including thousands of lithium batteries) burned, releasing toxic chemicals that kept fluctuating in the air six weeks later, with rain spreading toxins into soil and water rather than washing them away.
  • Mold industry fear-mongering has created unnecessary panic. Many inspectors and naturopaths fuel anxiety about air quality, leading to expensive home remediation that may not be needed, forming a self-reinforcing ecosystem of concern.
  • CO2 and oxygen levels in your home directly impact focus, mood, and performance. Poor ventilation affects everything from kids' classroom behavior to your sleep quality, yet we optimize diets and workouts while ignoring what we breathe 20,000+ times daily.
  • We ignore air quality because it's free and abundant. Unlike food or water that require purchase and have immediate taste feedback, air seems invisible and consequence-free, making it the most overlooked pillar of health despite its constant impact.
  • Improving air quality requires minimal daily effort for maximum health impact. Unlike meditation, journaling, or gym routines, clean air doesn't demand willpower every day, making it one of the most accessible ways to boost cognition, sleep, and recovery.
  • And much more...
