The New Science Of Breath: James Nestor On Why Most People Are Breathing Wrong

James Nestor, author and breathing expert, joins Rich Roll to discuss the widespread problem of dysfunctional breathing and its impact on health. Nestor argues that industrialized diets have led to smaller mouths and compromised airways, causing many to default to mouth breathing, which leads to shallow breaths, stress, and reduced oxygen delivery. He cites studies showing a link between mouth breathing and increased cavities, as well as sleep-disordered breathing and ADHD in children. Nestor advocates for nasal breathing, proper posture, and awareness of indoor air quality, noting CO2 levels in many buildings can negatively affect cognitive function. He shares personal experiences and actionable techniques, such as mouth taping and conscious breathwork, to improve breathing habits and overall well-being.
