5 Key Concepts
Physiology First
This is a core belief and approach that prioritizes understanding and optimizing the body's fundamental physical needs (sleep, exercise, nutrition, breathing, rest) as the prerequisite for mental health. It suggests that many 'mental health disorders' are natural physiological responses to an unnatural environment or unmet physical needs, rather than inherent disorders.
Anxiety as Order
This concept reframes anxiety not as a disorder, but as a natural, ordered physiological alarm system of the human body. It signals that certain physical needs (like sleep, movement, nutrition) are not being met, urging the individual to take action and reclaim optimal health.
State Control
This refers to the ability to consciously influence and regulate one's internal physiological dials, such as heart rate, mental focus, clarity, and energy levels. By understanding how these 'dials' work through training and exploration, individuals can gain agency over their physical and mental state.
Co-regulation
This describes how a leader or individual in an environment can influence and regulate the internal state of others around them. By modeling optimal mental and physical health, a teacher or coach can set the emotional and physiological 'temperature' of a room, impacting the nervous systems of those present.
Dopaminergic Cycle
Dopamine is a neurotransmitter that drives motivation and desire. When learning or activities are volitional and exciting, the dopaminergic response is heightened, leading to deeper engagement and more effective learning. Conversely, unvolitional or obligatory activities do not produce the same motivational increase.
11 Questions Answered
Parents should care because there's a global mental health crisis, yet the term 'mental health' from 1908 often pathologizes natural physiological responses to an unnatural environment. By focusing on physiology first, parents can give kids skills and tools to proactively manage increasing anxiety and depression.
Many issues labeled as mental health problems are downstream symptoms of unmet physical needs, such as insufficient sleep, lack of exercise, poor nutrition, or metabolic imbalances. When these foundational needs are not met, anxiety and depression are natural, ordered alarm systems of the body, not disorders.
Physiology First teaches students to experience anxiety in a controlled setting, often using an Airdyne bike to increase heart rate, then lowering it with breathing techniques. This helps them understand anxiety as a physical response they can control, debunking the idea that it's a disorder that just happens to them.
The Physiology First campus prioritizes learning about physiology, brain health, and self-development over just 'getting fit' or burning calories. It's an experiential learning environment rooted in principles, fostering community and agency, rather than a clinical or performance-focused gym setting.
Controlling one's internal state means learning to access and adjust the various 'dials' of one's physiology, such as heart rate, mental focus, clarity, and energy levels. This involves exploring through training how much one is capable of influencing these internal processes.
Cold plunges and saunas act as immediate teachers, triggering specific neurochemicals (like Adderall does) that improve focus. By understanding the science and mechanism, students learn to master accessing these benefits for free, entering these challenging environments with agency and a prepared skill set.
Teaching fundamental skills of breathing, nutrition, movement, and rest as a priority would lead to a massive paradigm shift, fundamentally challenging the idea that kids are disordered. It would demonstrate that humans are built to thrive and feel incredible, rather than being prone to depression and anxiety.
Caffeine and energy drinks can be a significant problem, especially for young people who metabolize caffeine slowly. Caffeine blocks adenosine receptors, leading to a 'crash' and compromising sleep, which is crucial for learning and emotional regulation. This can contribute to a permanently anxious state if not managed.
Parents can start by learning about breathing and teaching their children breath awareness and control. This serves as a doorway to understanding their physiology, improving self-awareness, emotional reactivity, and mental focus, and can lead to further learning about sleep, exercise, and nutrition.
Teachers should embody health principles through their own actions, modeling state regulation and optimal health. They should also be thoughtfully disruptive to the current system, for example, by allowing kids to stand and move, prioritizing sunlight and outdoor time, and integrating a physiologically-oriented curriculum.
Personal trainers can build trust by showing genuine care for individual physiology, such as having clients train barefoot to connect with foundational movement, or assessing breathing patterns to tailor exercises. This demonstrates a deeper understanding beyond generic programs and opens the door to discussing state control and neuroscience.
33 Actionable Insights
1. Prioritize Physiology First
When addressing mental health concerns, especially in young people, first assess and meet their fundamental physiological needs (metabolic, sleep, exercise, nutrition) as these are physical prerequisites for mental health to even be possible.
2. Reframe Anxiety as Trainable
Instead of viewing anxiety as a disorder, understand it as a natural physiological response that can be experienced, engaged with proactively, and managed by building specific skill sets.
3. Master Your Physiology
Learn to control your internal state by understanding and turning the ‘dials’ of your physiology, such as mental focus, clarity, cognition, and energy levels, to gain agency over your body’s responses.
4. Teach Fundamental Health Skills
Prioritize teaching children and adults fundamental skills in breathing, nutrition, movement, and rest to make a significant impact on rates of poor mental health and empower them to thrive.
5. Build Physical Health Community
Recognize that the community and relationships formed around health protocols are often more valuable than the protocols themselves; foster intergenerational, ongoing physical communities for deeper engagement and support.
6. Embody Health as a Leader
For teachers, parents, or coaches, embody health principles through your own actions and presence, as your state co-regulates the environment and models health effectively for others.
7. Practice Interoceptive Sensitivity
Develop self-awareness by regularly checking in with your body, for example, by asking ‘Where is my heart rate right now?’ to understand your internal state and physiological responses.
8. Use Controlled Discomfort for Training
Create environments where individuals can volitionally engage with discomfort, like increasing heart rate through exercise, and then teach them skills to exit that state, building resilience and agency.
9. Nasal Breathe 90% of Life
Prioritize breathing through your nose for 90% of your life, as it is a fundamental pathway to self-awareness, state control, and improved nervous system regulation.
10. Utilize the Physiological Sigh
To quickly lower your heart rate and regulate your state, practice the physiological sigh: inhale through the nose, follow with a second fuller inhalation, then exhale slowly and completely through the mouth.
11. Train Barefoot for Foot Awareness
Remove shoes during training to allow feet to function as the foundation for human movement, fostering deep sensory learning and improving awareness of how foot orientation affects overall body mechanics.
12. Understand CO2 Tolerance
Learn that feelings of breathlessness or anxiety during physical exertion are often due to rising CO2 levels in the body, not a lack of oxygen, and improve CO2 tolerance through breath-hold training and nasal breathing during exercise.
13. Manage Caffeine Timing & Impact
Understand the science of caffeine and its timing, especially its impact on adenosine (sleep chemical) and the nervous system, to prevent it from compromising sleep and contributing to chronic anxiety.
14. Prioritize Quality Sleep
Recognize that sleep is the foundation for mental health, emotional regulation, and learning; ensure sufficient, quality sleep to avoid increased amygdala activity and feelings of anxiety or moodiness.
15. Regular Exercise as Antidepressant
Understand that not exercising is a depressant, and regular physical activity is a critical driver for maintaining a state of feeling alive, engaged, and powerful, rather than depressed.
16. Reject Cynicism, Embrace Curiosity
Cultivate deep curiosity around every element of skill development, rejecting cynicism, to continuously improve and build skills in areas like breathing, walking, running, sleeping, and nutrition.
17. Disrupt Unhealthy Educational Norms
For school leaders and teachers, be thoughtfully disruptive by challenging and changing unhealthy practices, such as excessive sitting or homework that compromises sleep, to create healthier learning environments.
18. Allow Movement & Standing in Class
Integrate movement and opportunities for standing into the school day, as these are free physiological disruptors that can improve learning efficiency and brain health.
19. Invest in Staff Health Skills
School leaders should invest in training staff to develop and model state regulation and optimal mental and physical health, as this commitment is crucial for students to trust health education.
20. Prioritize Sunlight & Outdoor Time
School leaders should prioritize sunlight exposure and outdoor time for students and staff, integrating these elements into the daily schedule to support overall health and well-being.
21. Institute Physiology-Oriented Curriculum
School leaders should implement a deep physiologically oriented educational curriculum that teaches students how to navigate their nervous system in a complex, ever-changing modern environment.
22. Foster Volitional Engagement
Design learning and training experiences that are volitional and exciting, tapping into the dopaminergic system to increase motivation and deep engagement, rather than obligatory participation.
23. Avoid Single Domain Over-Fixation
While starting with specific health domains like breath is good, avoid over-fixation on any single area; instead, zoom out to integrate all foundational aspects of physiology for holistic health and purpose.
24. Assess Basic Biomarkers First
For practitioners, make health diagnoses with health data by first assessing basic physiological biomarkers, such as sleep quality, exercise levels, nutrition, and metabolic needs, before considering other interventions.
25. Avoid Disempowering Labels
For parents and practitioners, be cautious with labels like ‘disorder’ for natural physiological responses, as these can disempower individuals and prevent them from seeking lifestyle changes for different symptoms.
26. Implement Heat Acclimatization Training
Use regular sauna sessions or other heat acclimatization training to prepare the body for hot environments, which can reduce physiological stress and anxiety during activities like sports.
27. Warm-up Lungs & Heart Rate Gradually
Before intense physical activity, perform warm-ups that gradually bring up heart rate and prepare the pulmonary system, allowing for controlled physiological engagement rather than sudden high-intensity states.
28. Practice Foot Articulation
Develop control over your feet by practicing movements like lifting only the big toe or only the small toes, which improves foot facility and body awareness.
29. Tailor Exercise to Breathing Mechanics
For personal trainers, assess clients’ breathing patterns and rib cage function (e.g., front-to-back vs. side-to-side breathing) to select exercises that optimize muscular development and joint health, rather than exacerbating imbalances.
30. Use Cold Plunge/Sauna for Neurochemicals
Explore cold plunges and saunas as tools to trigger specific neurochemicals (e.g., dopamine, norepinephrine) for free, understanding their mechanism to access states of focus and energy without external stimulants.
31. Train Skills in Low-Consequence Settings
Coaches and educators should create environments where skills for high-stress situations can be trained with low consequence, allowing individuals to learn and have fun without the pressure of real-world stakes.
32. Build ‘Cool’ Health Infrastructure
Community leaders and entrepreneurs should create local spaces where learning about health and fitness is perceived as exciting and countercultural, attracting young people voluntarily to engage with their physiology.
33. Teach Kids to Feel the Difference
As a parent or coach, guide children to actively understand and feel the physiological differences when they engage in healthy behaviors (e.g., exercise, nasal breathing) versus unhealthy ones, fostering intrinsic motivation.
6 Key Quotes
It's not that exercise is an antidepressant, it's that not exercising is a depressant.
David Bidler
If anxiety and depression is an alarm system to put us back to a position of optimal health and we don't listen to it, or if we act as if it somehow shouldn't be going off, you're going to pathologize a generation of kids who, again, they don't need pathology. They need physical education that empowers and engages and actually excites them.
David Bidler
Education is agency. Education is physical and physiological agency. And without that, you're simply, you're training the mechanism, but you're not giving people mastery of the mechanism.

3 Protocols
Experiential Anxiety Management Training
David Bidler- Invite students to 'get some anxiety' to build a proactive skill set.
- Place students on an Airdyne fan bike in a comfortable, non-clinical environment with friends and music.
- Instruct students to bike at an easy pace, breathing only through their nose for one minute.
- Have students practice breathing exercises on the bike: 5-second inhalation and 5-second exhalation, going as fast as possible while maintaining nasal breathing and the count.
- Change the breathing count to a 5-second inhale and a 10-second exhale.
- After the bike, discuss the physical sensations experienced and explain that anxiety is a physiological response that can be managed.
- Teach specific breathing exercises (e.g., physiological sigh) to lower heart rate and exit the anxious state.
Physiological Sigh for Heart Rate Reduction
David Bidler- Inhale deeply through the nose.
- Follow with a second, fuller inhalation through the nose to really fill the lungs.
- Exhale slowly and completely through the mouth, as if fogging up a distant glass or mirror.
Addressing Panic Attacks Related to Physical Activity
David Bidler- Assess and implement heat acclimatization training (e.g., regular sauna use).
- Train individuals to gradually bring up their heart rate during warm-ups, rather than going from zero to high intensity immediately.
- Improve carbon dioxide (CO2) tolerance through breath hold training and nasal breathing during workouts.
