How Breathing Through Your Nose Will Change Your Life with Patrick McKeown

Nasal, Slow, Light Breathing Improves Sleep, Stress, Exercise and Health

1. A.McKeown describes how switching from mouth to nose breathing at around 26 transformed his asthma, sleep and alertness, and argues that dysfunctional breathing is widespread and overlooked.
2. B.He argues that nasal breathing supports diaphragmatic, slower breathing, oxygen uptake and delivery, nitric oxide benefits and an open airway during sleep, and links mouth breathing to sleep apnea risk and poorer sleep.
3. C.The conversation covers how mouth breathing and diet in childhood may affect jaw, face and airway development, with McKeown citing orthodontic research and stressing it is never too late to change.
4. D.McKeown teaches practical tools: the BOLT score (25 seconds as a minimum), exhale breath-holds to unblock the nose, slow breathing at six breaths per minute, and nasal breathing during exercise, with cited studies on efficiency and sprint performance.
5. E.He compares his CO2-tolerance approach with the Wim Hof method, warns against breath-holding after hyperventilation near water, and recommends mouth taping, observing your breathing, and trying the practices for two weeks.
