Unlock your Body's Clock: The Science of Circadian Rhythm

Welcome to the science of the Circadian Rhythm, your body’s 24-hour internal clock that controls sleep, hunger, metabolism, and more. Influenced by natural light and darkness, this rhythm helps you wake up, stay alert, and prepare for rest. Hormones like melatonin signal bedtime, cortisol boosts morning alertness, and insulin regulates blood sugar. Understanding and aligning with your circadian rhythm can enhance your health and productivity. And it's one of those aspects of our life that best combines traditional wellness knowledge across civilisations with modern day scientific explanations for why it works. But what is challenging is how modern day lifestyles are often out of sync with this. Summary 6am-8am: Low melatonin, high cortisol, low blood sugar Ideal for light cognitive tasks 8am-12pm: Post-breakfast: insulin normalizes blood sugar High cortisol and energy levels Best time for cognitively challenging work Light exercise can release endorphins, boosting mood and energy 12pm-3pm: Post-lunch: insulin manages blood sugar Cortisol decreases, melatonin increases Not ideal for challenging cognitive tasks Carb-heavy meals can cause a sugar spike and crash 3pm-6pm: High body temperature enhances physical performance Best time for gym, though work schedules may interfere 6pm-9pm: Sunset: melatonin increases, cortisol decreases Time for relaxation Avoid high-carb meals due to decreased insulin sensitivity Prefer light meals or high protein and fiber Reduce screen exposure and prepare for sleep Chapters 00:00 - Introduction to Circadian Rhythm 02:54 - SLEEP - Melatonin 04:02 - HUNGER - Ghrelin & Leptin 04:55 - METABOLISM - Insulin 06:04 - ALERTNESS & STRESS - Cortisol 06:32 - BODY TEMPERATURE 06:55 - Getting in sync with your body's clock 09:25 - Tradition vs Science PS: There is now a Masala Lab Board Game!
