Beyond the Bed: How Getting Up is the Path to Quicker Recovery
lundi 8 juin 2026 • Durée 16:56
In this episode, we dive into the surprising science of "gravity intolerance" and why lying in bed might be one of the worst things you can do for your recovery. Whether you're dealing with a common flu, recovering from major surgery, or managing a long-term illness, the simple act of gettingvertical can be a "physics-fighting engine" for your body and mind. We explore NASA’s "Pillow-naut" studies, the link between inactivity and depression, and how hospitals are using "Art Tours" and gamification to get patients back on their feet.
Key Takeaways:
The Danger of Deconditioning: Staying flat for too long leads to "gravity intolerance," affecting everything from your cardiovascular system to your gut health (Ileus).
The NASA Lesson: Lessons from simulated space environments show that lying down causes fluid shifts that lead to headaches, vision issues, and a "shock to the system" when finally standing up.
The 1,000 Step Rule: Patients who can manage just 1,000 steps the day after surgery are significantly more likely to be discharged faster.
MentalGravity: Physical inactivity and depression aren't just cause-and-effect; they are a feedback loop. Standing up is a literal and metaphorical way to fight mental "pull".
Timestamps:
00:00 – The "Hit by a Bus" Feeling: Personal memories of COVID and the exhaustion of illness.
01:22 – The Hospital Dilemma: Why we put our sickest patients in bed and the risks of being "risk-averse".
02:15 – What Happens to Your Body When You Stay Flat: Gut slowing (Ileus), skin breakdown, and cardiovascular deconditioning.
03:00 – Lessons from NASA: The "Pillow-naut" studies and what happens when gravity stops pulling blood to your ankles.
04:30 – The Shock of Getting Vertical: Why the first walk after a long illness feels like the Earth is a magnet.
05:30 – Fighting for Your Life: The story of Harman Clark and the mindset shift required for recovery.
07:30 – Gamifying Recovery: Using Fitbits and "Art Tours" at Cedars-Sinai to encourage patient movement.
09:40 – Moving Beyond "Standing Orders": The importance of walking vs. just sitting in a chair.
11:15 – Being an Active Participant: Why you shouldn't wait for recovery to happen—you have to give it a nudge.
12:30 – The Connection to Mental Health: How inactivity heightens the risk of depression and helplessness.
14:30 – "Mental Gravity": A new way to look at the feedback loop between the mind and body.
16:00 – Final Thoughts: Next time you feel down, think about standing up.

Artemis: Transcending gravity as human flourishing
jeudi 23 avril 2026 • Durée 36:12
In this episode, Dr. Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr. Lachlan Kent(cognitive scientist and founder of Mental Gravity) explore the physical, psychological, and existential implications of humanity's return to the moon.
They examine how the Artemis mission acts as a "Global Unifier," shifting the narrative from territorial conflict to a collective human achievement.
Broadcasting as a "crew of two," they reflect on the transition from the stoic, emotionally restrained era of Apollo to the joyful, diverse, and deeply "human" experience of modern space exploration. They connect the physics of "untethering"from Earth to the metaphysics of "mental gravity," arguing that space travel is the ultimate expression of humanity's anti-gravity mission.
One Giant Leap for Humanity: The ArtemisPerspective
A Global Unifier: A 21st-century mission that transcends national borders, bringing the world together to witness one of humanity's greatest achievements.
The Physics of Fragility: An exploration of the "immense forces" required to fight gravity and the vulnerability of the human body in zero-G environments.
The Overview Effect: The profound psychological realization that occurs when astronauts look back at the planet and see it not as a collection of countries, but as a single "crew" on Spaceship Earth.
Humanizing Space: A shift from the "stoic" pilots of the 1960s to a mission characterized by visible joy, big hugs, and diverseleadership.
Space Travel as a Biogravitational Mission
Breaking the Tether: Humanity’s evolutionary history is defined by standing up and using intelligence to build machines that allow us to fly and eventually "blast off" from the planet.
The Two Portals: Space travel forces a confrontation with two realities: the "awe-inspiring" view of home and the "existential dread" of the black void.
Kurt Cobain and the Gravity of Child Development with Dr Mats Niklasson
lundi 2 mars 2026 • Durée 01:10:12
Dr Lachlan Kent is joined by Dr Mats Niklasson, developmental psychologist, visiting Research Fellow at the University of Greater Manchester, and co-founder of Sensorimotor Therapy, to explore how early vestibular development shapes both physical coordination and the narrative sense of self.
Drawing on nearly 40 years of clinical work with children and adults experiencing coordination and concentration difficulties, Mats explains how early reflexes—especially the Moro (startle/falling) reflex—connect infants to gravity. When these developmental processes are disrupted, the result may be delayed motor patterns, emotional dysregulation, learning challenges, and even later-life identity instability.
Using the life of Kurt Cobain as a psychobiographical case study, the conversation explores how gravitational insecurity may influence creativity, mental health, and the lifelong struggle to feel “at home” in one’s own body.
Check out Mat's book on the topic: "The discovery of international autoethnographical psychobiography"
A developmental approach grounded in movement and balance
Focuses on vestibular activation and early motor patterns
Links physiology and psychology through embodied development
Works by re-engaging early fetal-style movements
The goal:Reconnect the nervous system with gravity to release arrested development
Primary Reflexes & Early Development
All infants are born with survival reflexes
The Moro reflex is closely tied to the vestibular system

All loved "UP" on Valentines Day: Gravity and cuffing season
samedi 14 février 2026 • Durée 21:43
Dr Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr Lachlan Kent (cognitive scientist and founder of Mental Gravity) explore how seasons, sunlight, serotonin, and gravity shape mood, attraction, and human connection.
Broadcasting from opposite hemispheres—Brennan in winter in Los Angeles and Lachlan in summer in Melbourne—they examine why people often feel more “down” in winter, why this is linked to reduced sunlight and serotonin, and how this helps explain the phenomenon known as “cuffing season”—the seasonal urge to pair up.
They connect dating, love, posture, breath, yoga, serotonin, oxytocin, and even planetary orbits into a single biogravitational story: human connection is shaped by the same gravitational cycles that shape the seasons themselves.
Seasons as Gravitational Cycles
Seasons arise from Earth’s orbit around the sun Not just temperature cycles, but gravitational and light cycles
Sunlight boosts serotonin Low winter sunlight → lower serotonin → heavier mood Seasonal Affective Disorder (SAD) as a gravity-related mood state Serotonin as a “gravity management molecule” that supports:
Muscle tone
Circulation
Upright posture
Mental elevation
Love, Attraction, and Gravity
“Falling in love” uses gravitational language Uprightness—physical, emotional, moral—is attractive Winter dating favors depth over displaySpring favors peacocking; winter favors bondingLong-term connection as gravitational alignment of values
How the Brain Senses Gravity — with Elisa Ferrè
vendredi 6 février 2026 • Durée 39:09
Dr Lachlan Kent and Dr Brennan Spiegel are joined by Elisa R. Ferrè, professor of cognitive neuroscience at Birkbeck, University of London, and one of the world’s leading experts on graviception and the vestibular system.
Together, they explore how the brain senses gravity without a single “gravity receptor,” why the vestibular system has no primary cortex, and how gravity is computed as a distributed, multisensory model integrating vestibular, visual, proprioceptive, and visceral signals. The conversation spans neuroscience, emotion, aesthetics, culture, spaceflight, and mental health—revealing gravity as the hidden scaffolding of perception, meaning, and wellbeing.
1. What Is Graviception?
The brain’s ability to sense and model gravityNot driven by a single receptor or cortical areaConstructed through multisensory integrationFundamental to embodiment, orientation, and survival
Why the Vestibular System Is Unique
No unimodal “vestibular cortex” Projects broadly across the brain Does not produce a clear conscious sensation Becomes noticeable mainly when something goes wrong (dizziness, vertigo, nausea)
The vestibular system acts as the glue binding mind and body, anchoring us in a single embodied perspective.
How the Brain Computes Gravity

EMERGENCY EPISODE: Alex honnold’s incredible gravity-defying climb
mardi 27 janvier 2026 • Durée 18:58
Dr Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr Lachlan Kent (cognitive scientist and founder of Mental Gravity) drop an emergency episode to unpack one of the most extreme acts of gravity defiance ever witnessed: Alex Honnold climbing a 100-plus-storey skyscraper without ropes.
Using Honnold as an “extreme phenotype,” they explore what his remarkable calm reveals about fear, anxiety, graviception, and mental gravity. Drawing on neuroscience, psychology, and lived experience, they examine how Honnold’s quiet amygdala, finely tuned salience network, and relentless present-momentfocus allow him to operate where most humans would be paralysed by fear.
The episode bridges elite performance and everyday mental health, asking: what can the rest of us learn—safely—from someone who literally does not fear falling?
1. Why Alex Honnold Matters
A real-world example of ultimate gravity resilienceFree-solo climbing as the most literal test of mental gravityAnxiety, fear of falling, and bodily panic stripped awayA window into the far edge of human psychological capacity
Fear, Falling, and the Brain
Amygdala Honnold’s amygdala shows minimal activation to fear-inducing stimuli Contrast with anxiety, chronic pain, IBS, and fibromyalgia, where the amygdala is hyper-vigilant
Salience Network & Anterior Insula Detects what matters in the body and environment Simulates graviceptive cues without triggering panic Anchors awareness in the present moment
Being in the Moment—Taken Seriously
Honnold’s survival depends on microsecond-level presence No anticipatory anxiety, no future projection Finger placement, balance, and movement solved in real time Presence as an adaptive skill—not a slogan
Defying Gravity: The Olympics and the Limits of Human Performance - Ep 9
jeudi 15 janvier 2026 • Durée 21:14
How do elite athletes use body, mind, joy, and meaning to push beyond physical limits?
Dr Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr Lachlan Kent (cognitive scientist and founder of Mental Gravity) explore theOlympics as humanity’s greatest laboratory for defying gravity.
With the Winter Olympics approaching, they examine elite athletes as “physics-fighting engines”—bodies and minds trained to resist, redirect, and sometimes seemingly escape gravity. Through stories of Cathy Freeman, Quincy Hall, Alex Honnold, and modern superstars like Steph Curry and Luka Dončić, they show how peak performance is not just physical—it is mental gravity management.
They introduce Olympic training as a real-world expression of biogravitational medicine, where strength, balance, imagery, joy, poise, team culture, and meaning all shape how far humans can push their relationship with gravity.
1. Why the Olympics Matter to Mental Gravity
The Olympics showcase humanity at the edge of physical limits
Elite sport = everyday gravity management taken to extremes Athletes model what it means to fight gravity physically and mentally Peak performance = synchronization of body, brain, and meaning
Athletes as Anti-Gravity Prototypes
Cathy Freeman (Sydney 2000) “Floating” to gold in the 400m Home crowd as acceleration, not pressure Up, light, fast = opposite of depression
Turning failure into flightLast-minute mental reversal → physical transcendence
Serotonin: The Body’s Anti-Gravity Molecule - Ep 8
samedi 20 décembre 2025 • Durée 18:23
Dr Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr Lachlan Kent (cognitive scientist and founder of Mental Gravity) explore serotonin as a gravity-management molecule, reframing it not simply as a “happiness chemical,” but as a fundamental biological system that allows life to stand up, move fluids, regulate balance, and remain psychologically buoyant in a gravitational field.
Together, Brennan and Lachlan unpack new research on serotonin’s role across the gut, cardiovascular system, lymphatics, vestibular system, reproduction, and mood—showing how 95% of serotonin is produced in the gut, in symbiosis with the microbiome. They trace serotonin’s evolutionary origins from ocean life to land, altitude, and even space, and discuss practical implications for diet, exercise, sunlight, microbiome care, and mental health.
1. What Is Serotonin?
A whole-body gravity resilience molecule, not just a brainneurotransmitter
Exists in two largely separate compartments: brain and gut Central to movement, circulation, balance, mood, and vitality Evolutionarily conserved across plants, animals, and humans
Serotonin as a Gravity-Management System
Gut & DigestionMotility against gravity in any body orientation
Balance& OrientationVestibular function; dizziness during SSRI withdrawal
Reproduction Retrograde uterine contractions that move sperm upward against gravity
Mood &Energy Mental elevation, vitality, resilience, and time perception

Brennan's antigravity diet - Boost your serotonin with STACK TEN Ep 7
lundi 8 décembre 2025 • Durée 28:13
Dr Brennan Spiegel (physician, gastroenterologist, and author of Pull) and Dr Lachlan Kent (cognitive scientist and founder of Mental Gravity) explore how diet, microbiome diversity, and serotonin production shape your capacity to stand up to gravity—physically and mentally.
They introduce the Anti-Gravity Diet and Brennan’s STACK TEN framework, a simple, evidence-informed way to support the gut’s serotonin “factories” and improve whole-body gravity resilience. Along the way, they unpack how food, fibre, omega-3s, polyphenols, vagus-nerve activation, and mindful rest all participate in the body–mind system that keeps us upright and energised.
Together, Brennan and Lachlan discuss babies as “gravity novices,” leaky gut, the gut–brain axis, evolutionary embodiment, time dilation in depression, and why serotonin—serum tone—is essential for managing the constant downward pull of Earth’s gravity.
A holistic framework for supporting natural serotonin production—the body’s anti-gravity molecule. Grounded in gastrointestinal physiology, microbiome science, and biogravitational medicine.
Not a restrictive diet — a practical, everyday toolkit for gravity resilience.
A memory device for foods that supply the raw material (tryptophan) for serotonin production:
Fibre → feeds microbes that create short-chain fatty acids
Omega-3s → shift the microbiome toward serotonin-supporting species
Polyphenols → found in berries, cocoa, turmeric, and green tea

Crawling patterns may be skipped
Walking and speech may be delayed
Concentration and coordination may suffer
Vestibular development sits on a continuum—not simply “normal” vs “impaired”
Reconnecting to Gravity
Therapy works by:
Recreating early fetal movement patterns
Engaging attachment between child and caregiver
Stimulating vestibular systems
Observed outcomes include:
Return of expected motor patternsImproved regulationReduction in headaches and stomach achesThis suggests a deep link between vestibular development and whole-body wellbeing
From Body to Biography
Mats connects early vestibular insecurity to later psychological outcomes:
Development is trajectory-based
Small early deviations may compound over time
Identity itself may emerge from embodied stability.
Kurt Cobain as Case Study
Niklasson’s analysis suggests:
Possible early developmental difficulties
Verified diagnoses included scoliosis and chronic bronchitis
Chronic stomach pain remained unexplained
He may have suffered from IBS—undiagnosed in his lifetime
Vestibular instability may have influenced:
Sensitivity
Withdrawal
Creativity
Search for equilibrium
Niklasson proposes Cobain may have been “a victim of his time,” lacking modern frameworks to understand syndrome-like conditions
Creativity & Instability
Drawing on Coleridge’s distinction between:
Fancy imagination (common)
Secondary imagination (rare, generative)
Some creative individuals may channel instability into talent.
Therapeutic balance is key:
Stability may reduce suffering
But may also alter creative expression

Winter Practices for Gravity Resilience
Movement & Posture Yoga as a winter-friendly anti-gravity practice Inversions, posture, alignment, balance Low-intensity movement over intense training
Light &Environment Maximize sunlight exposure Use light boxes in high-latitude winters Get outside when possible
Diet & Chemistry Tryptophan-rich foods: turkey, avocado, chicken, chickpeas, kidney, beans, eggs, tofu, nuts Support serotonin production through diet
Connection Cuddling, closeness, bonding Oxytocin release Oxytocin → vagus nerve → serotonin Parasympathetic “rest and digest” state
Human health reflects planetary physics Sun, moon, Earth, and orbit shape biology Mood, love, and seasons are not mystical—just natural Gravity as the hidden organizer of emotion, posture, and connection

Up = good, free, elevated Down = heavy, negative, constrained
Emotion, Fear, and the Vestibular System
Vestibular pathways connect directly to:
Amygdala
Insula
Hypothalamus
This explains why vestibular disturbances are emotionally chargedDizziness and vertigo trigger fear, nausea, and autonomic responses Gravity sensing is deeply tied to survival systems
Weightlessness and Freedom
Parabolic flight (“vomit comet”) as a unique graviceptive state Weightlessness described as profound freedom Also physiologically challenging Post-flight “down” feelings mirror return to gravity
Freedom comes with a cost: sensory conflict and adaptation demands.
Space Adaptation & Neuroplasticity
Astronauts experience space motion sickness Symptoms: nausea, disorientation, brain fog The brain can adapt through neuroplasticity Adaptation takes time, energy, and training
Implicationsfor long-term space travel and Mars exploration.
Gravity, Mental Health, and Everyday Life
Anxiety as mis-tuned gravity anticipation Depression as altered temporal and bodily grounding Mental fitness as trainable gravity resilience
Tools discussed:
Yoga and posture
Breath awareness
Grounding through the feet
Weighted blankets
Music, rest, and multisensory regulation
Practical Graviceptive Tip
Stand still and feel the pressure through the soles of your feet Notice the security of 1G Use grounding as a way to reduce anxiety and reset expectations

Humans vary widely in tolerance for heights, G-forces, and risk Too much fear → paralysis Too little fear → danger Healthy functioning lies in the middle of the curve
Mental Gravity, Anxiety, and Depression
Anxiety = anticipation of falling Depression = being stuck or weighed down in the present Honnold represents the opposite extreme: calm within gravity Insights help reframe everyday anxiety as mis-tuned gravity perception
Training vs Talent
Honnold combines rare inborn traits with years of intense training Physical: extreme strength, precision, endurance Mental: emotional regulation, present-moment focus Fear is not absent—it is managed and contained
What Can We Learn (Safely)?
Not to climb skyscrapers—but to train mental fitness:
Cognitive Behavioural Therapy as mentaltraining
Meditation as present-moment conditioning
Breathwork, yoga, and grounding practices
Social connection and rest as recovery
Balancing effort and recovery (noovertraining)
Mental fitness = something you work on, not something you either have or don’t have.
