In this video, Patrick McKeown from Buteyko Clinic International explains how your breathing directly affects your brain function, blood flow, oxygen delivery, and even your sleep quality and mental performance.

In this video, you’ll learn: - Why mouth breathing and fast, upper-chest breathing can: - Reduce blood flow to the brain - Cause blood vessels to constrict - Lead to over-excitable brain cells and scattered thinking The role of carbon dioxide (CO₂) and the Bohr effect in: - Regulating blood pH - Helping red blood cells release oxygen more easily to the brain - How poor breathing during sleep can: - Increase snoring - Leave you tired and mentally foggy the next day - Why improving your breathing is essential if you want to: - Be calm, focused, and creative - Have good energy and a better mood - Reach your full potential Patrick also introduces the Buteyko Method as a simple, scientifically grounded breathing approach to: - Improve blood flow - Enhance oxygen delivery - Stimulate the vagus nerve - Improve sleep quality - Support brain health and performance If you find this video helpful, please subscribe to support the Buteyko Clinic channel so we can continue creating more content on: - Functional breathing - Mouth vs. nose breathing - Sleep, snoring, and apnea - Nervous system regulation and the vagus nerve 📌 Subscribe to the channel for more videos on breathing, health, and performance. #Buteyko #ButeykoMethod #PatrickMcKeown, #brainhealth #breathingtechnique #brain #mouthbreathing #nosebreathing, #carbondioxide #CO2
