Mood, anxiety, psychiatry, and the biology behind how we feel.
Neuroscientist Richard Davidson says wellbeing is a trainable skill, not a fixed trait. He organizes this into four pillars (awareness, connection, insight, purpose) and shows five minutes of daily meditation for 28 days lowers IL-6, an inflammation marker, and shifts gut microbiome pathways; purpose best predicts longevity after age 70.
Scott Barry Kaufman closes 11 years and 478 episodes of The Psychology Podcast with seven lessons on human potential, personality change, and creativity. He argues neuroticism is the easiest Big Five trait to shift and openness the hardest, and that lasting change comes from habits, not willpower (09:06, 15:22).
Sleep cycles every 90 minutes, and early cycles release growth hormone and clean the brain, while later ones handle emotion and creativity. Neurobiologist Gina Poe explains how REM sleep silences the stress chemical norepinephrine, letting the brain separate emotion from memory, and why consistent bedtimes protect this whole system.
Stanford psychologist Alia Crum finds that beliefs about food, stress, illness, and genes can alter body chemistry itself. Labeling an identical milkshake indulgent rather than sensible triples the drop in the hunger hormone ghrelin (12:37), and believing one carries a low-efficiency exercise gene lowers real oxygen conversion regardless of actual genotype (47:10).
Regular arts engagement cuts depression risk in half over ten years and leaves brains measuring five to seven years younger than actual age, UCL research shows. Psychobiologist Daisy Fancourt's cohort studies tie the effect to dopamine, emotional distance from difficult art, and cognitive reserve, holding even with 10 to 20 minutes of daily practice.
