Natural Health and Bio-Individual Healing

Like Duolingo, but for Natural Health and Bio-Individual Healing. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

79 levels across 9 sections, about 158 minutes end to end, roughly 32 days at five minutes a day. It moves through The Nervous System Master Switch, The Gut-Brain Axis and Microbiome Mastery, Metabolic Flexibility and Blood Sugar Control, Hormonal Harmony and Endocrine Support, Detoxification Pathways and Lymphatic Flow, Immune Resilience and Inflammation Control, Circadian Biology and Environmental Health, Advanced Nutritional Strategies, and The Mind-Body Connection and Longevity. It assumes you already know the basics.

What you'll learn

Key ideas in Natural Health and Bio-Individual Healing

  • High vagal tone allows for a rapid return to homeostasis after a stressor
  • Vagal tone is a measure of how quickly the parasympathetic system can inhibit the sympathetic response
  • Splashing ice-cold water specifically on the face and eyes activates the dive reflex
  • The dive reflex overrides the sympathetic nervous system to prioritize oxygen conservation
  • Application of cold thermogenesis to trigger the mammalian dive reflex
  • The vagus nerve passes through the larynx and is physically stimulated by vocal cord vibration
  • Low-frequency humming creates a mechanical 'massage' for the laryngeal branch of the vagus
  • The Ventral Vagal Complex links cranial nerves for facial expression to the sinoatrial node of the heart
  • Mechanical stimulation of the laryngeal vagus branch
  • Social engagement behaviors like soft eye contact actively inhibit the 'fight or flight' response
  • Linking facial expressions and social engagement to cardiac regulation
  • Exhalation is the phase of breath associated with vagal braking and heart rate deceleration
  • Understanding the mechanical stimulation of the laryngeal vagus branch
  • Lengthening the exhale relative to the inhale signals the brainstem that the environment is safe
  • Sequencing a breath pattern to maximize parasympathetic signaling
  • HRV tracks the millisecond-level timing gaps between individual heartbeats
