From asthma and anxiety to sleep quality, athletic performance, focus, and recovery, Patrick explains why the way you breathe may be quietly shaping nearly every aspect of your health. The conversation dives into the surprising science of CO2 tolerance, why most people are chronically over-breathing, and how simple shifts – like nasal breathing, breath holds, and slowing your exhales – can dramatically change your nervous system and performance. Patrick also breaks down why women experience breathing and sleep differently than men, how poor breathing affects kids’ development and behavior, and why many sleep disorders may be going undiagnosed. Most importantly, this episode is packed with practical tools you can start using immediately – whether you’re trying to sleep better, feel calmer, improve endurance, or simply function better under stress.
