    Party Smart: Understanding Risks and Staying Safe

    In this episode of Science Savvy, we speak with Pablo Otero, who holds a PhD from Imperial College London and has been involved with the organisation Drugs and Me, about harm reduction and the science behind recreational substances. We discuss how these substances affect the body, why and how mixing them can increase your risk, and practical, evidence-based ways to make safer decisions in party settings. Disclaimer: This episode does not encourage or endorse recreational drug use. In fact, much of the conversation focuses on why avoiding these substances is the safest option. However, because some people may still choose to take them, this episode aims to provide factual, science-based information that may help reduce the risk of harm.

    When Your Brain Turns Down the Pain: Pain and the brain part 3

    This episode explores how pain is not just a bodily signal but a brain-made experience shaped by context, expectations, and emotions. It covers top-down modulation (stress or adrenaline can suppress pain; mood can amplify it), the role of placebo and endogenous opioids, and surprising findings sugar pill placebo effects. It also summarizes practical, non-pharmacological strategies like cognitive behavioral therapy, exercise, mindfulness, pain education, and social support, that engage the brain’s own analgesic systems to reduce pain or improve coping.

    I need RELIEF!!! Pain and the brain part 2

    Part two of this Science Savvy pain series explains how common painkillers work, why many provide limited relief, and how pain is shaped by nerves, the spinal cord, the brain, and emotion!! (emotion?!?!)... we even talk about porn, sexual arousal, and its impact on pain... the ffff The episode covers common drugs like ibuprofen, paracetamol, local anesthetics (at your dentist office) through to not-so-common drugs like opioids.

    It HURTS! Pain and the Brain part 1

    Pain is weird. You only feel it in your brain… yet your brain has no pain receptors. In part 1 of this 3-episode series, we unpack why pain is less a “signal” and more a decision your nervous system makes to feel it, shaped by reflexes, memory, mood, and context. You will learn why a hot stove makes you yank your foot back before you even feel anything, how “sharp” and “throbbing” travel on different nerve highways, and why chronic pain can become a disease of its own. We discuss mind-bending paradoxes like phantom limb pain, referred pain (why heart attacks can hurt in your arm/jaw rather than your heart), and why two people with the same injury can rate pain totally differently.   Bibliography: Greenwald BD (2012).

    Sleeping Tight and Why It Matters: The Science of Sleep - Part 1

    This episode explores why sleep is SUPER important for body repair, immune function, literally cleaning your brain, and protecting you from diseases like Alzheimer's. We get into some FUN topics like dreams: why we dream, whether there are any benefits to dreaming, and how sleep is different for different animals. Give it a listen, and stay tuned for part two!

    Going on a Trip: Science of Psychedelics

    In this episode, I explore the history, science, and clinical promise of psychedelics. This was actually my Master's Thesis topic so very fun episode for me! We cover everything from how the psychedelics actually work, by acting brain (serotonin) receptors to increase neuroplasticity (make your brain more malleable), disrupt rigid brain patterns, and increase brain "entropy"... and, more importantly, why those effects may help us treat conditions such as PTSD and treatment‑resistant depression. The episode also discusses the current clinical evidence (including a critical appraisal of its robustness), logisitcal and ethical challenges, and the importance of use within therapeutic / research settings only. As always, find a full bibliography below: Carhart-Harris & Goodwin (2017), “The Therapeutic Potential of Psychedelic Drugs: Past, Present, and Future,” Neuropsychopharmacology - This one is a very good foundation if you only have time to read one paper, it should be this one!!
