David Rönnlid Podcast

🌍 How can we align our lives — and our societies — with our body clocks?Poor sleep and circadian misalignment don’t just make us tired — they impair several aspects of our metabolic health. I sat down with Jonathan Cedernaes, M.D., Ph.D., and explored what we can do about it: from personal daily habits to systemic policy reforms. Sleep quality and quantity isn’t just about recovery — it’s a public health issue.We dive deep into:✅ Daily habits that keep your circadian rhythm aligned✅ Why sleep timing is as important as sleep duration✅ How late nights and irregular schedules impair metabolism and long-term health✅ Policy changes that could protect circadian health at a population level — from school start times to shift work regulations✅ The promise of circadian science for future treatments and prevention strategies💡 What do you think matters more for our collective health: better personal habits or policy reforms?#SleepScience #CircadianHealth #Metabolism #PublicHealthSleep science group: https://www.facebook.com/groups/495466987134152/Connect with Jonathan on social media:X: https://x.com/jcedernaesIG: https://www.instagram.com/sleepydrcedernaesclocks/Episode chapters:00:00:00 Introduction00:02:05 Sleep as a Driver of Motivation and Healthy Habits00:04:15 Weekend Catch-Up Sleep: Benefits and Limits00:07:50 Sleep, Metabolic Health, and Obesity Links00:10:13 Sleep Disruption and Neurodegenerative Disease00:12:53 Mechanisms: How Neurodegeneration Impairs Sleep00:18:30 Supplements, Exam Stress, and Slow-Wave Sleep00:20:01 The Body's Master Clock in the Brain: The Suprachiasmatic Nucleus00:23:20 Light, Retina, and the Body’s Internal Timekeeping00:43:16 Late-Night Eating and Sleep Quality00:46:00 Heart Rate Variability: What It Really Tells Us00:52:10 Short Sleepers, Long Sleepers, and Individual Needs01:05:22 Circadian Misalignment: Jet Lag and Shift Work01:19:44 Sleep and Mental Health Connection01:33:11 Diet Timing, Fasting, and Circadian Rhythm01:43:52 Exercise After Sleep Loss: Helpful or Harmful?01:56:20 MicroRNAs, Sleep Loss, and Neurodegeneration Risk02:14:36 AI, Research, and Sleep Science in the Future02:22:06 Summary of most important takeaways from the conversation

Most of us think of different types of cholesterol as either “good” or “bad.” But the reality is more complex.Daniel Elías-López, Endocrinologist, Ph.D, is a Mexican endocrinologist and researcher whose work spans both clinical care and public health. After years of treating patients with obesity, diabetes, and lipid disorders, he saw a limit to what could be achieved in the clinic alone. That realization led him toward research—with work aimed at generating knowledge that could inform prevention and treatment strategies for millions.In this episode, we discuss:- Why LDL is only part of the picture- How elevated cholesterol can remain asymptomatic for years, and why early measurement is important for timely risk detection- Practical, evidence-based strategies that can help lower risk for cardiovascular eventsRather than claiming to have all the answers, Dr. Daniel Elías-López shares his insights from clinical experience and research —highlighting what’s known, what’s emerging, and why prevention matters.You can connect with Dr. Daniel Elías-López on LinkedIn: https://www.linkedin.com/in/danieleliasl/ and listen to his podcast in Spanish: https://open.spotify.com/show/31RDgmiIWXQHyHNjgBxeNe?si=6bdf7f42589f4af6Episode chapters:00:00:00 - Why lipoproteins are essential for human health 00:07:14 - Research motivation behind studying cholesterol particles 00:14:53 - How lipoprotein particle size affects heart risk 00:22:00 - The main types of cholesterol in the body 00:29:40 - Understanding non-HDL cholesterol and health impacts 00:36:50 - Genetics and their influence on lipid metabolism 00:44:02 - Strategies to improve current cholesterol guidelines 00:51:41 - How cholesterol knowledge translates to clinical practice 00:58:49 - Fasting versus non-fasting lipid blood testing 01:06:29 - What cholesterol levels really tell about health 01:13:40 - Additional lipid markers for cardiovascular assessment 01:20:55 - Current debates in cholesterol research and policy 01:28:30 - Impact of diet on lipid profile and heart health 01:36:10 - Future directions in lipid research and prevention 01:43:55 - Key takeaways and summary of cholesterol insights

Parkinson’s disease is now the fastest-growing neurological disorder in the world — and according to Dr. Ray Dorsey, it’s not just about aging or genetics. Dr. Dorsey argues that environmental toxins — including certain pesticides, industrial chemicals, and air pollutants — are significant, modifiable risk factors for developing Parkinson’s disease. In this podcast episode, we discuss:🔬 The evidence linking environmental toxins to Parkinson’s disease💡 What individuals can do today to reduce their exposure to environmental toxins that research has shown are associated with increased risk for developing Parkinson's disease🏛 The public health policy changes Dr. Dorsey advocates to address the rapid rise of Parkinson’s disease in today’s society.Dr. Dorsey's book "The Parkinson's Plan": https://www.amazon.com/Parkinsons-Plan-Path-Prevention-Treatment/dp/1541705386Episode chapters:00:00:00 Episode highlight reel00:02:11 Introducing Dr. Ray Dorsey, Parkinson’s Disease Researcher00:04:43 Evidence Linking Long-Term Exposure to Trichloroethylene to Neurological Decline 00:08:10 Environmental Contributions to Parkinson’s Beyond Genetics 00:12:37 Communicating Risks Without Overstating the Evidence 00:16:47 Historical Use and Persistence of Paraquat in Agriculture 00:19:20 Testing Options for Potential Parkinson’s-Related Risk Factors 00:21:48 Why Parkinson’s Risk Reduction Remains a Global Challenge 00:24:51 Practical Measures to Limit Environmental Neurotoxins 00:30:40 The Role of Policy in Reducing Harm 00:33:05 How Public Awareness Can Drive Change in Exposure

Louise Hecker, PhD, is a scientist of the cellular mechanisms of aging, such as oxidative stress and endogenous antioxidant enzymes in lung tissue and how such mechanisms influence development of fibrotic lung tissue. During the early phases of this study on the effects of psilocbin on aging in human cells and mice, she was an Associate Professor at Emory University, whereas toward the final data analysis and manuscript preparation, she held the same position at Baylor College of Medicine.The study discussed in this episode investigated psilocybin’s ability to prolong cellular lifespan and reduce oxidative stress in human fibroblasts, and it reported that higher doses extended cellular lifespan dose-dependently by up to 57 %. In aged mice, monthly psilocybin dosing markedly improved survival and even restored fur color and hair growth. Both the cell study and the mouse study suggest that psilocybin targets multiple hallmarks of aging, possibly even reversing some age-related processes.The study, "Psilocybin treatment extends cellular lifespan and improves survival of aged mice": https://www.nature.com/articles/s41514-025-00244-xYou can connect with Dr. Hecker on LinkedIn: https://www.linkedin.com/in/louise-hecker-69ba1915/ and on X: https://x.com/heckerlouise.Episode chapters:00:00:00 Can psilocybin slow cellular aging?00:03:29 Introducing aging researcher Dr. Louise Hecker00:08:24 The psilocybin-telomere hypothesis explained00:10:18 What telomeres are & why they shorten with age00:17:14 Psilocybin makes old cells "behave" like young cells00:23:23 Regulatory hurdles of psilocybin research00:25:54 Checking cancer risk & cell division results00:30:12 Measuring life extension in cells00:36:34 Scar tissue, fibroblasts & aging00:42:25 When to start treatment & dosing of psilocybin for maximum anti-aging effects?00:46:38 Designing the psilocybin mouse study00:57:28 Mice live longer & look younger after monthly psilocybin dosing01:07:44 Unanswered questions & follow-up studies01:27:44 Implications for chronic diseases

Please beware of the risks of exposing your skin to sunlight in general and UVA light in particular. A large body of evidence suggests that UVA light exposure on the skin can increase risk for various skin cancers. This podcast episode is not intended as a recommendation to increase your personal amount of time spent in the sun. The decision of how much sunlight to expose your skin to is yours to make. This podcast episode is intended to raise awareness of only some of the effects of UVA in order to help you make that decision an informed decision. So, in the name of increasing awareness of all of the effects of sunlight on human health, please take into consideration not only the potential positive psychological effects that were mentioned in this episode, but also some established harmful somatic effects of UVA light:https://www.skincancer.org/risk-factors/uv-radiation/Study link: https://pmc.ncbi.nlm.nih.gov/articles/PMC113771/Study reference: Gambichler T, et al.
