This is an educational course focused on explaining breathing and carbon dioxide tolerance in a clear, structured way.
The course is primarily text based, using written explanations to explore how breathing and CO₂ are discussed in physiology and nervous system education. Guided breathing examples are included to help illustrate key concepts and support understanding, rather than to prescribe practice or achieve specific outcomes.
The emphasis throughout is on clarity, context and learning, allowing you to engage with the material at your own pace.
What this course is about
This course explores how breathing and carbon dioxide tolerance are commonly described in relation to physiology, attention and regulation.
You will look at how CO₂ relates to oxygen delivery and blood chemistry, and how breathing patterns are often discussed within wider conversations about stress, fatigue and regulation.
The focus is on understanding the ideas clearly, rather than trying to change, optimise or control your breathing.
Inside the course
The course is organised into structured sections that build understanding over time.
Inside the course, you will find:
• Clear, text based explanations of breathing and CO₂ tolerance
• Simple diagrams and written examples to support understanding
• Guided breathing examples used to illustrate key ideas
• Discussion of common misconceptions around breathing and regulation
• A calm, flexible structure that allows you to read, pause and revisit material as needed
How the material is presented
Throughout the course, you will be invited to:
• Read short, focused explanations of key concepts
• Use guided breathing examples as illustrations of the ideas discussed
• Reflect on how the information fits with your existing understanding
• Engage with the material without pressure to practise or progress
There is no requirement to perform exercises or achieve specific results. The course is designed to support understanding, not outcomes.
Who this course is for
This course is for anyone interested in learning more about breathing and CO₂ tolerance from an educational perspective.
It may be of interest to people who are curious about breathing related sensations, such as air hunger, and want to better understand how these experiences are discussed in physiology and nervous system education. It may also be of interest to coaches or practitioners who want a clearer conceptual framework.
No prior knowledge or experience is required.
