Summary (short version): Why does winter feel heavier for some of us? In this episode, we explore the neuroscience of Seasonal Affective Disorder — from circadian rhythms and serotonin pathways to evolutionary quirks and the strange possibility that humans may still carry traces of ancient hibernation biology. Learn why your brain struggles with short days, how morning light acts as a natural antidepressant, and practical strategies to help your winter self thrive.I share my own experience with winter mood shifts, what the science says about why they happen, and — most importantly — the tools we can use to reclaim our energy and wellbeing during darker months.Three Tools for Your Super Brain Kit:Light before screens — Get bright light within 30 minutes of waking (10–20 minutes outdoors or a 10,000-lux lamp).Anchor your day — Keep wake and sleep times consistent to stabilise your circadian rhythm.Reverse-winter habits — Add small dopamine-rich rewards before difficult tasks, not after, to counter low motivation.Each episode explores what’s really going on inside your brain when you do the things you do — from the everyday to the extraordinary — and gives you three tools for your Super Brain kit.

Why are we so much harsher on ourselves than we are on others? In this episode of Super Brain, I explore the neuroscience of self-compassion — what it is, what it isn’t, and why it’s the antidote to self-criticism.Drawing on the work of Dr Kristin Neff and Buddhist philosophy, we’ll look at self-compassion as a three-part skill: self-kindness, mindfulness, and social connection. I’ll share research showing how self-compassion reduces stress, quiets the amygdala, and activates brain regions linked to empathy and emotional regulation.I’ll also explain why self-criticism is a form of self-harm, and why self-compassion is a foundation for flourishing and manifesting happiness, resilience, and contentment.As always, I’ll wrap up with my Tools in Three — simple ways you can start turning up your brain’s kindness switch today.Each episode explores what’s really going on inside your brain when you do the things you do — from the everyday to the extraordinary — and gives you three tools for your Super Brain kit.

Psilocybin — the psychedelic compound in so-called “magic mushrooms” — has exploded into headlines and social media feeds. Some call it a miracle cure for depression, others dismiss it as hype. In this episode, I take a clear-eyed look at what the science really says.I’ll start with Sarah’s story — a young scientist whose life was turned upside down by a cycling accident and who found hope again through a psilocybin clinical trial at Johns Hopkins. Her words: “This trial changed my life.”From there, I explore:The history of psilocybin, from ancient rituals to 1960s psychiatry to today’s “psychedelic renaissance.”The online buzz, where psilocybin is hyped as everything from a creativity booster to a trauma cure.The scientific evidence, from small pilot trials to the largest modern RCTs.The neuroscience, showing how psilocybin may “reset” rigid brain networks, boost plasticity, and even dampen inflammation.The risks, including panic, paranoia, and psychosis in vulnerable people.Finally, I’ll share my Tools in Three so you can separate the real promise from the hype.Featured ResearchCarhart-Harris RL, et al. doi: 10.1016/S2215-0366(16)30065-Carhart-Harris RL, et al. doi: 10.1056/NEJMoa2032994Davis AK, et al. doi: 10.1001/jamapsychiatry.2020.3285Goodwin GM, et al.

Why do we put off the very things that matter most? In this episode of Super Brain, I explore procrastination — the irrational gap between what we want to do and what we actually do. From ancient Greek philosophy to modern neuroscience, we’ll unpack why our brains resist long-term goals in favour of short-term mood fixes.I’ll share two leading theories that explain procrastination, what’s happening in the brain when we delay, and why the closer the deadline, the more motivated we become.And of course, my Three tools for your Super Brain kit will give you practical strategies to shrink tasks, hack your “future you”, and harness the magic of deadlines.Procrastination is deeply human — but it doesn’t have to rule your life.References:📖 The Neuroscience of Manifesting (Dr Sabina Brennan) – on making your goals personal and vivid so they feel worth acting on today.📚 Research on procrastination from psychology, philosophy, and neuroscience.Each episode explores what’s really going on inside your brain when you do the things you do — from the everyday to the extraordinary — and gives you three tools for your Super Brain kit.
