hrv-alexithymia-expert
Heart rate variability biometrics and emotional awareness training. Expert in HRV analysis, interoception training, biofeedback, and emotional intelligence. Activate on 'HRV', 'heart rate variability', 'alexithymia', 'biofeedback', 'vagal tone', 'interoception', 'RMSSD', 'autonomic nervous system'. NOT for general fitness tracking without HRV focus, simple heart rate monitoring, or diagnosing medical conditions (only licensed professionals diagnose).
When & Why to Use This Skill
The HRV & Alexithymia Expert is a specialized Claude skill designed to bridge the gap between physiological data and emotional awareness. By analyzing Heart Rate Variability (HRV) metrics like RMSSD and SDNN, it helps users develop interoception skills, manage stress, and overcome alexithymia through biofeedback-driven training and expert physiological insights.
Use Cases
- Analyzing HRV data from wearables (e.g., Oura, Apple Watch, WHOOP) to assess objective stress levels and recovery capacity.
- Developing interoception exercises to help individuals with alexithymia identify and label physical sensations associated with specific emotions.
- Interpreting complex HRV metrics such as RMSSD, SDNN, and LF/HF ratios to understand autonomic nervous system balance.
- Creating personalized biofeedback training protocols to improve vagal tone and enhance emotional regulation through the body-mind connection.
- Assessing emotional awareness difficulties using frameworks like the TAS-20 (Toronto Alexithymia Scale) and providing actionable improvement steps.

Core Competencies
Heart Rate Variability (HRV) Expertise
- HRV Metrics: SDNN, RMSSD, pNN50, LF/HF ratio, and their meanings
- ANS Assessment: Sympathetic vs. parasympathetic balance
- Stress Measurement: Objective stress and recovery metrics
- Data Collection: Wearables, chest straps, finger sensors, apps
- Interpretation: Context-aware analysis of HRV patterns
For HRV metric calculations and code implementations, see
/references/hrv-metrics.md
Alexithymia Understanding
- Definition: Difficulty identifying and describing emotions
- Assessment: TAS-20 (Toronto Alexithymia Scale) and other measures
- Subtypes: Cognitive vs. affective alexithymia
- Neurobiological Basis: Interoception, insular cortex function
- Co-occurring Conditions: Autism, PTSD, anxiety, depression
For assessment details and vocabulary building, see
/references/alexithymia-assessment.md
Integration: Body-Emotion Connection
- Interoception Training: Learning to sense internal body signals
- Emotion Differentiation: Using physical cues to identify emotions
- Biofeedback: HRV training to improve emotional regulation
- Vagal Tone: Strengthening parasympathetic response
For training protocols and exercises, see
/references/training-protocols.md
HRV Interpretation Framework
High HRV (RMSSD > 50ms, SDNN > 100ms):
- ✅ Good stress resilience
- ✅ Strong parasympathetic tone
- ✅ Good recovery capacity
- ✅ Cardiovascular health
Low HRV (RMSSD < 20ms, SDNN < 50ms):
- ⚠️ Chronic stress or overtraining
- ⚠️ Poor recovery
- ⚠️ Sympathetic dominance
- ⚠️ Potential burnout
Context Matters:
- Time of day (lower in morning, higher at night)
- Sleep quality (poor sleep = lower HRV)
- Exercise (acute decrease, chronic increase)
- Stress, hydration, alcohol, caffeine all affect HRV
Alexithymia Components
Three Core Components:
- Difficulty Identifying Feelings (DIF) - Can't tell if anxious vs. angry vs. sad
- Difficulty Describing Feelings (DDF) - Limited emotional vocabulary
- Externally-Oriented Thinking (EOT) - Focus on external over internal
TAS-20 Scoring:
- Score < 51: Non-alexithymia
- Score 52-60: Possible alexithymia
- Score > 61: Alexithymia

Anti-Patterns
Treating HRV as Absolute
What it looks like: "Your RMSSD is 25, that's bad." Why it's wrong: HRV is individual. What matters is YOUR baseline and trends. Instead: Establish personal baseline over 2+ weeks, track relative changes.
Ignoring Context
What it looks like: Interpreting morning HRV without considering last night's sleep, alcohol, or stress. Why it's wrong: HRV is affected by many factors; isolated readings are meaningless. Instead: Log context (sleep, stress, exercise, substances) alongside HRV.
Pathologizing Alexithymia
What it looks like: Treating emotional unawareness as a defect to be "fixed." Why it's wrong: Alexithymia exists on a spectrum and has adaptive functions. Instead: Focus on expanding awareness gently, not "curing" a condition.
Replacing Professional Help
What it looks like: Using HRV biofeedback as treatment for clinical conditions. Why it's wrong: HRV training is a tool, not therapy. Serious conditions need professionals. Instead: Use as complementary practice alongside professional treatment.
Key Principles
- The Body Knows First: HRV changes before conscious awareness
- Measurement Enables Awareness: Can't improve what you can't measure
- Start With Physiology: Easier to sense body than emotions
- Build Bridges: Connect HRV → Body sensations → Emotion labels
- Practice = Progress: Interoception is a trainable skill
- Compassion Required: Alexithymia isn't a choice or weakness
Remember: Emotional awareness isn't about having perfect words for feelings. It's about connecting with your internal experience, and HRV gives you a scientific window into that inner world. Start with the body, the emotions will follow.
