The Brain Professor: "Popular Treat Now Considered Deadlier Than Smoking!", "Alcohol Is Shrinking Your Brain" - David Raichlen

As humans we have evolved to move, but why are we getting it wrong so often? David Raichlen is the Professor of Human and Evolutionary Biology at the University of Southern California. His research focuses on the connection between human evolution, physical activity, and health, examining why inactivity leads to so many chronic diseases in the modern world. In this conversation David and Steven discuss topics, such as how modern exercise levels compare to hunter-gatherers, the dangers of sitting, how air pollution is linked to dementia, and the misunderstanding of just how much exercise it takes to get health benefits. 00:00 Intro 01:59 My Work: How Lifestyle & Exercise Affects the Brain 03:07 You Can Change an Ageing Brain 05:22 What Is a Neuron? 05:36 What Is the Hippocampus 07:28 The Link Between Exercise and Brain 09:06 What Happens to Our Brain When We Don't Exercise 12:54 People Aren't Meeting the Guidelines for Good Health 15:25 What Activities Are Good for Our Brain? 17:35 Orienteering Can Train the Brain 18:47 How the Different Types of Exercise Increase Neuroplasticity 22:39 Impact of Exercising in Greener Spaces Than Urban 24:06 Better Cognition Exercising Before a Task 25:41 The Optimal Time of the Day to Exercise 27:46 The Hadzas: Researching Hunter-Gatherer Tribes & the Findings 28:56 What Is the Optimal Exercising Time? 31:59 Cardiovascular Illnesses in Hadza Tribe 35:07 What's the Issue with Sitting? 40:29 The Power of Daily Small Amounts of Exercise 42:17 How to Improve Memory 46:08 Top Factors That Fuel Cognitive Problems 48:38 Link Between Human Connection & Brain Impact 50:54 Pollution Impact on the Brain 53:13 Racquet Sports for Brain Health 54:41 How Much Activity Do I Have to Do? 55:52 Endocannabinoid Receptors and Exercise Rewards 57:24 Mental Health Issues Linked to Lack of Exercise 01:01:45 Brain Foods 01:03:07 Reaching Optimal Living 01:07:50 What Causes Alzheimer's? 01:12:39 Last Guest Question Follow David: Twitter - https://bit.ly/483oZIF Watch the episodes on Youtube - https://g2ul0.app.link/3kxINCANKsb My new book!
