Shownotes

Most of us never question how we breathe. Yet many of us over-breathe or mouth-breathe without realising it. In this episode, investigative journalist and international bestselling author James Nestor shares four breathing techniques to retrain your nervous system and support better health.

This episode is for anyone who feels stressed, snores, wakes up tired, or wants a simple way to improve their health. James, who has spent over a decade researching breathing science with leading respiratory experts, guides us through daily breathing habits to help calm your body, improve oxygen efficiency, and support long-term wellbeing. We explore why nasal breathing is more efficient, how slow breathing can influence the nervous system, and how modern lifestyles may have reshaped our airways.

If breathing is something you do 20,000 times a day, what might change if you retrained it?
