This episode I describe the biology of two essential hormones we all make: cortisol and adrenaline (also called epinephrine). Cortisol and adrenaline powerfully regulate our levels of energy, focus and immune system function. I describe various science-supported tools and practices to increase or decrease cortisol and/or adrenaline, depending on one's specific needs and goals. I also describe the biology of nootropics, and how cortisol and adrenaline can improve or degrade learning. Finally, I review the scientific data and tools for timing the release of these hormones to improve memory, energy and immune system function.Read the full show notes for this episode at hubermanlab.com.Thank you to our sponsorsAG1 (Athletic Greens): https://athleticgreens.com/hubermanLMNT: https://drinklmnt.com/hubermanlabWaking Up: https://www.wakingup.com/hubermanTimestamps00:00:00 Introduction 00:00:31 Sponsors: AG1, LMNT & Waking Up 00:05:41 Energy & Your Immune System, & Learning Faster 00:08:34 Why & How Intermittent Fasting Increases Growth Hormone 00:11:56 Why Your Stomach Growls 00:13:09 Hot Baths & Hormones 00:14:35 Energy, Adrenaline (Epinephrine), & Cortisol 00:15:48 Cortisol & Cholesterol, Competition With Testosterone & Estrogen 00:17:54 Adrenaline (Epinephrine) Is Your (Immune System’s) Best Friend 00:18:48 Cortisol Basics In Two (Actually 1) Minute/s 00:19:48 Adrenaline Basics In Two Minutes 00:21:32 Tool: Time Your Cortisol Peak To Waking Using Specific Light Intensities 00:27:20 Brief Increases In Cortisol & Adrenaline Boost Energy, Focus & Immunity 00:30:04 Ways To Increase Adrenaline, Epinephrine & Cortisol & Why That Is Good 00:35:00 Does Mindset During Stress Matter? 00:36:15 Protocols: Adrenaline Breathing Described 00:39:00 Practices To Increase Energy Without Increasing Stress 00:45:00 Using Stressors to ENHANCE Our Immune System: Science & Tools 00:55:11 Timing Thyroid Release For Energy 00:57:02 Adrenaline/Stress Increase Performance & Memory.
