The Factors That Control Your HRV Ceiling
An explanation of the non-modifiable factors like age, genetics, and sex that dictate your baseline heart rate variability.
The Cruise Control for Your Blood Pressure
An explanation of the baroreflex response and how a dysregulated nervous system acts like a 'crappy' old car's cruise control, leading to poor mental acuity and physical overshooting.
State Changes vs. Trait Changes in the Nervous System
Understanding the difference between acute interventions that change your state immediately and long-term training that builds a more robust nervous system.
HRV vs. VO2 Max: The Truth About Health Metrics
An important clarification on why HRV shouldn't be used as a vanity metric or a catch-all health score, especially when compared to more robust metrics like VO2 Max.
Why the Relaxation Response is Faster Than Stress
A counter-intuitive insight into human biology: the parasympathetic nervous system (the 'parachute') actually responds faster than the sympathetic nervous system (the 'fight or flight' response).
The Scientific Gap in Popular Breathwork
Dr. Wiles critiques the general field of breathwork, pointing out that many popular methods lack the robust evidence for long-term 'trait change' that resonance breathing possesses.
Breathing as a Signal of Safety
Using the mountain lion analogy, Dr. Wiles explains why slowing your breath is the most direct way to tell your brain you are in a safe environment.
The Latitude Effect: How Sickness Changes Your Personality
Dr. Jay Wiles explains 'latitude' or 'sickness behavior,' where physiological states like being unwell trigger specific behavioral shifts such as avoiding new foods and seeking social safety.
What is Heart Rate Variability (HRV)?
Dr. Jay Wiles provides a comprehensive definition of HRV, explaining why it's the most powerful non-invasive window into the state of our nervous system.
Why Precision Beats Effort in Breathwork
Dr. Jay Wiles explains why hitting the exact resonance frequency for breathing is critical for maximizing heart rate variability gains, noting that even a small deviation can significantly reduce the benefits.
The Metronome Myth: Why a Steady Heartbeat is Dangerous
A counter-intuitive explanation of why a perfectly rhythmic heart is actually a sign of distress, and why 'chaos' in your heartbeat is the goal.
Why You Can't Change the Mind With the Mind
Dr. Wiles explains the 'bottom-up' approach to mental health, arguing that it is often more efficient to regulate the body to change the mind than to rely solely on cognitive processing.
Stop Comparing Your HRV Scores to Other People
Dr. Jay Wiles debunks the virtue signaling around high HRV scores, explaining why stability and individual baselines matter more than absolute numbers.
The Nervous System Gym: Training for Trait Change
Dr. Wiles uses a powerful analogy comparing breathing exercises to a gym workout, explaining how consistent practice leads to long-term physiological adaptations rather than just temporary state changes.
Why Sleep is the Canary in the Coal Mine for Health
Dr. Wiles highlights sleep as the non-negotiable foundation of health, explaining how it acts as a repair mechanism for the nervous system and how HRV data during sleep reveals true baseline regulation.
The Gold Standard Protocol for Resonance Breathing
A detailed breakdown of the optimal frequency and duration for resonance breathing to achieve long-term nervous system adaptation and HRV improvement.
Your Nervous System Gym: HRV Training vs. Relaxation
A crucial mindset shift regarding breathwork; Dr. Wiles argues that HRV biofeedback should be viewed as training or a 'gym' for the nervous system rather than just a relaxation tool.
The Norivirus Lesson: When Your Body Decides Your Mood
Chris Williamson shares a personal anecdote about being irritable and 'catty' with staff, only to realize later that his bad mood was actually the first symptom of an oncoming stomach bug.
