In this episode, I describe a comprehensive toolkit consisting of behavioral and supplement-based tools that you can customize to enhance the quality, duration and impact of your sleep. This has an enormous positive impact on your overall health and daytime functioning, brain, hormones and immune system. I teach you how to effectively harness light (and darkness), temperature, food, exercise, caffeine, supplements, and digital devices in order to fall asleep faster, stay deeply asleep longer and overall, and achieve better quality sleep. I also describe how these tools can be modified to recover quickly from a poor night’s sleep, jet lag or bouts of shift work. Given that sleep is the foundation of all mental health, physical health and performance, this episode should benefit everyone as it provides an essential toolkit of science-supported, low- to zero-cost strategies that can be tailored to optimize your sleep routine.
