About this listen

A New Podcast Hosted by Aaran Vijayakumaran Ph.D, a Scientist at Stanford University

Curious Together | Exploring science, mind, and meaning

Welcome to The Vitality Lab — a podcast about the science of being human. This show blends physiology, psychology, and philosophy to explore what it means to grow, adapt, and live with intention.

It's a space for people who ask why we are the way we are, and what we can do about it. We don’t claim to have the answers — but we believe in asking better questions. Whether it’s the stress of endurance, the complexity of the mind, or the search for meaning, this podcast invites you to think more deeply about the forces shaping our lives. Because the world is full of rich information — and we’re here to make sense of it, together.

New episodes weekly. For the curious. For the seekers. For those still becoming.

  • What Actually Helps When You’re Struggling | Professor Pooja Saini
    Dec 28 2025

    Professor Pooja Saini is a UK-based academic and practitioner specialising in mental health, suicide prevention, and community-based support, with years of experience working at the intersection of research, healthcare, and real-world services.

    In this conversation, we explore why mental health is still so hard to talk about, why people often struggle in silence, and how misunderstanding, stigma, and system design shape the way we respond to distress. Rather than slogans or motivation, this episode focuses on understanding — what actually helps people cope, recover, and feel supported before things reach crisis.

    This episode is for anyone who wants to better understand mental health — whether for themselves, for someone they care about, or simply to have more compassionate and informed conversations.

  • Why Exercise Helps Depression — Why Starting Is So Hard | Dr Emily Hird
    Dec 25 2025

    In this episode, we’re joined by Dr Emily Hird, a cognitive neuroscientist and research fellow at University College London’s Institute of Cognitive Neuroscience, whose research focuses on the brain mechanisms underlying depression and other mental health conditions.

    Dr Hird’s work examines how changes in reward processing, motivation, and effort-based decision-making contribute to symptoms such as anhedonia and apathy. Her research also explores how dopamine signalling, inflammation, and stress interact in depression — and why physical activity may help by reshaping these brain circuits over time.

    Together, we unpack why depression isn’t just a change in mood, why everyday tasks can feel disproportionately effortful, and why exercise can be as effective as antidepressants for some people. Rather than focusing on willpower or “pushing through,” this conversation looks at the neuroscience of effort, small wins, and how understanding the brain can make recovery feel more possible.

    Topics covered

    • How depression changes brain function
    • Anhedonia, apathy, and effort sensitivity
    • Dopamine, reward circuits, and motivation
    • Inflammation and mental health
    • Why exercise helps depression (neuroscience explained)
    • Why starting small matters

    This episode is for education and discussion, not medical advice. If you’re struggling, consider speaking to a healthcare professional.

  • Anxiety & Intrusive Thoughts: How To Break the Loop | Dr Blake Stobie
    Jan 18 2026

    Dr Blake Stobie is the Lead Consultant Clinical Psychologist and Director at the Centre for Anxiety Disorders and Trauma (CADAT) in London. With over 25 years of experience treating anxiety, obsessive-compulsive disorder, PTSD and related conditions, Dr Stobie blends deep clinical insight with a warm, evidence-based approach to understanding the mind.

    We dive into the surprising truth about intrusive thoughts, what they really tell us about how our mind works, and why nearly everyone experiences them — even if they feel bizarre or upsetting. Dr Stobie reframes these thoughts not as flaws or warnings, but as a normal part of human cognition, and shows how anxiety and rumination can take over when we give too much weight to the stories we tell ourselves.

    If you’ve ever felt pulled into a spiral of worry or wondered why your brain seems to “spam” you with distressing ideas, this conversation offers clarity, compassion, and a path toward breaking the loop.
