In this Huberman Lab Essentials episode, I explore science-backed protocols to combat jet lag, manage shift work, and optimize sleep across different stages of life. I discuss “temperature minimum” — a simple and reliable measurement that helps you quickly adjust to new time zones and counteract the negative effects of nocturnal shift work. I also provide actionable tools for regulating sleep and wake cycles in babies and new parents. The episode emphasizes the critical role of circadian rhythms, influenced by factors like light exposure, temperature regulation, and eating schedules. Practical tools include using light to shift your circadian clock, understanding the role of temperature in sleep, and adopting strategies to improve rest without medication. Whether you’re a shift worker, a parent of a newborn, or someone facing sleep challenges, this episode offers valuable guidance for enhancing recovery and overall well-being.
