Your phone is not just distracting you, it may be changing what your brain finds rewarding.In this episode of Dr Karan Explores, Dr Karan Rajan speaks with neuroscientist TJ Power, founder of DOSE Lab, about dopamine, phone addiction, AI, “brain rot,” digital anhedonia, and why modern technology can make ordinary life feel less pleasurable. TJ’s DOSE framework focuses on dopamine, oxytocin, serotonin, and endorphins, the four brain chemicals he says are being disrupted by the way modern humans live. This conversation explores why so many of us feel stuck in loops of scrolling, distraction, apathy, and low motivation, and what it takes to reset our relationship with stimulation without pretending technology is “bad.” TJ shares why he believes 72 hours without screens can feel transformative, why boredom is harder than it sounds, and why becoming a “professional unplugger” may be one of the most important skills for the next generation. In this episode, we cover:What dopamine actually does beyond the online “dopamine detox” clichésWhy phones, short-form content, sugar, alcohol, and AI can hijack reward pathways“Digital anhedonia”: Why normal life can start to feel dull or boringThe 72-hour unplugged experiment and what happens by day two and day threeWhy boredom, stillness, walking, and doing nothing can restore creativityThe default mode network and why your best ideas may need silenceAI, “brain rot,” passive screen time, and outsourcing your thinkingHow to become a “professional unplugger” without quitting modern life🎬 Chapters01:13 – Why Modern Life Is Rewiring Our Brains03:18 – What Dopamine Actually Does06:06 – Phones, Short-Form Content & Dopamine Overload09:28 – Why Nothing Feels Fun Anymore12:27 – How to Break the Stimulation Loop14:01 – 72 Hours Without Screens: What Happens to Your Brain17:49 – Boredom, Creativity & the Default Mode Network21:41 – Instant Gratification and the Collapse of Waiting22:47 – AI, Brain Rot & Outsourcing Your Thinking29:34 – Passive Screen Time vs Active Technology Use32:37 – Are Some Brains More Dopamine-Hungry?39:04 – Stillness, Silence & Rebuilding Attention42:35 – AI Relationships, Oxytocin & Artificial Connection46:10 – Why Technology Evolves Faster Than the Human Brain48:27 – Dopamine and Why Time Feels Faster52:03 – Becoming a Professional Unplugger53:31 – Final Takeaway: Quiet Mornings, Coffee & No Phone💩 Head to https://loamscience.com/products/loam-prebiotic-fiber-formula?utm_source=youtube&utm_medium=social&utm_campaign=drkaranexplores to try LOAM - and get an additional 10% with code POD10.💊 Get my free weekly newsletter filled with easy to action health tips, interesting facts and science to fill your curiosity: https://drkaran.beehiiv.com/subscribe🚽 Discover Throne's incredible new smart toilet device at http://thronescience.com📘 For more useful science for your everyday life, grab my best selling book "This Book May Save Your Life": https://geni.us/DrKaranBook📕 Get my new book, This Is Vital Information, here: https://linktr.ee/ThisisVitalInformation🤖 Discover my digital twin here: http://DrKaran.ai🧬 Sign up for my Microbiome Course waitlist: https://drkaran.kit.com/microbiome-course-waitlistAbout Dr Karan:Dr. Karan Rajan is a doctor, author, and educator dedicated to making health and medical science accessible to all.

Sleepwalking into arthritis isn’t inevitable. And some changes can show up faster than most people expect.In this episode, Dr Karan Rajan speaks with Professor Tamiko Katsumoto about why arthritis rates are rising, the differences between rheumatoid arthritis and osteoarthritis, and what the best evidence says about reducing joint inflammation, including a lifestyle medicine intervention where benefits were seen as early as 8 weeks (with the primary endpoint at 16 weeks).This isn’t about “miracle cures.” It’s about stacking the odds in your favour: Diet quality, fibre, fermented foods, weight and metabolic health, sleep, stress, movement. And how these interact with inflammation, the gut, and joint symptoms.In this episode, we cover:∙ RA vs OA: Classic symptom patterns and why they’re treated differently∙ Why treatments for osteoarthritis can feel limited (and why lifestyle is still worth discussing)∙ “Food as medicine” and why joints are a symptom you can actually feel change∙ The “Plants for Joints” study: What changed at 8 weeks and what the 16-week endpoint showed∙ The gut-joint axis: Gut barrier, microbial diversity, and immune regulation∙ Why some patients flare on ultra high meat / fibre-free approaches (and what to do instead)∙ Practical “build my plate” guidance for joint and inflammation support#Arthritis #JointPain #RheumatoidArthritis #Osteoarthritis #Inflammation💩 Head to https://loamscience.com/products/loam-prebiotic-fiber-formula?utm_source=youtube&utm_medium=social&utm_campaign=drkaranexplores to try LOAM - and get an additional 10% with code POD10.💊 Get my free weekly newsletter filled with easy to action health tips, interesting facts and science to fill your curiosity: https://drkaran.beehiiv.com/subscribe🚽 Discover Throne's incredible new smart toilet device at http://thronescience.com📘 For more useful science for your everyday life, grab my best selling book "This Book May Save Your Life": https://geni.us/DrKaranBook📕 Get my new book, This Is Vital Information, here: https://linktr.ee/ThisisVitalInformation🤖 Discover my digital twin here: http://DrKaran.ai🧬 Sign up for my Microbiome Course waitlist: https://drkaran.kit.com/microbiome-course-waitlistAbout Dr Karan:Dr. Karan Rajan is a doctor, author, and educator dedicated to making health and medical science accessible to all.
