All loved "UP" on Valentines Day: Gravity and cuffing season

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 CyclesSeasons arise from Earth’s orbit around the sunNot just temperature cycles, but gravitational and light cyclesMood follows seasonal gravity:Summer = outward, expansive, lightWinter = inward, heavy, contractingBreath mirrors this cycle: in/up, out/downWinter, Serotonin, and Mental GravitySunlight boosts serotoninLow winter sunlight → lower serotonin → heavier moodSeasonal Affective Disorder (SAD) as a gravity-related mood stateSerotonin as a “gravity management molecule” that supports:Muscle toneCirculationUpright postureMental elevationLove, Attraction, and Gravity“Falling in love” uses gravitational language Uprightness—physical, emotional, moral—is attractiveWinter dating favors depth over displaySpring favors peacocking; winter favors bondingLong-term connection as gravitational alignment of valuesWinter Practices for Gravity ResilienceMovement & PostureYoga as a winter-friendly anti-gravity practiceInversions, posture, alignment, balanceLow-intensity movement over intense trainingLight &EnvironmentMaximize sunlight exposureUse light boxes in high-latitude wintersGet outside when possibleDiet & ChemistryTryptophan-rich foods: turkey, avocado, chicken, chickpeas, kidney, beans, eggs, tofu, nutsSupport serotonin production through dietConnectionCuddling, closeness, bondingOxytocin releaseOxytocin → vagus nerve → serotoninParasympathetic “rest and digest” stateNeurochemistry of Winter BondingOxytocin primes vagus nerveVagus nerve regulates serotonin releaseCuddling + calm = anti-gravity physiologyParasympathetic tone matches seasonal slowingBiogravitational Medicine in Daily LifeHuman health reflects planetary physicsSun, moon, Earth, and orbit shape biologyMood, love, and seasons are not mystical—just naturalGravity as the hidden organizer of emotion, posture, and connectionTimecodes00:00 — Welcome & hemispheres01:15 — Seasons and gravity02:15 — What is cuffing season?03:15 — Mood, winter, and seasonal affect04:40 — Sunlight, serotonin, and heaviness06:05 — Planetary cycles and breath cycles07:15 — Love as anti-gravity08:15 — Depth vs display in dating09:20 — Uprightness and attraction10:45 — Winter activities and posture11:35 — Yoga and winter gravity13:15 — Balance, breath, and alignment15:40 — Light therapy and sunlight16:40 — Diet and serotonin foods16:55 — Cuddling, oxytocin, vagus nerve18:15 — Parasympathetic winter mode19:05 — Biogravitation and planetary life20:35 — Falling in love & falling physically21:00 — Closing reflectionsResourcesThe Gravity Doctors: https://thegravitydoctors.comDr Brennan Spiegel: https://brennanspiegelmd.comDr Lachlan Kent: https://lachlankent.auBook — Pull: How Gravity Shapes Your Body, Steadies the Mind, and Guides Our Health
