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. Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday. Read the full show notes for this episode at hubermanlab.com.

Full Episode
Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine.
Today's podcast episode is about jet lag, shift work, and we are going to discuss protocols that are backed by science that can support particular tools that you can use to combat things like jet lag
offset some of the negative effects of shift work and make life easier for the new parent, as well as for the newborn child, the adolescent, anyone that wants to sleep better, feel better when they're awake, et cetera. Let's just take a step back for a moment and remind everybody what we're talking about. The circadian rhythm is a 24 hour rhythm in all sorts of functions.
The most prominent one is a rhythm in our feelings of wakefulness and sleepiness. You also have a rhythm in sleepiness and wakefulness that correlates with that. We tend to be sleepy as our temperature is falling, getting lower, and we tend to be more awake or waking when our temperature is increasing. We have a clock over the roof of our mouth. called the suprachiasmatic nucleus.
That clock generates a 24 hour rhythm. And that clock is entrained, meaning it is matched to the external light dark cycle, which is no surprise, 24 hours. Spinning the earth takes 24 hours. So our cells, our organs, our wakefulness, our temperature, but also our metabolism, our immune system, all of that is tethered to the outside light dark cycle.
And if we are living our life in a perfect way where we wake up in the morning and we view sunlight as it crosses the horizon, and then by evening we catch a little sunlight, and then at night we're in complete darkness, we will be more or less perfectly matched to the external or ambient light-dark cycle.
Very few of us do that because of these things that we call artificial lights and this other thing that we call life demands. So today we're going to talk about when we get pulled away from that rhythm. So what is the perfect day? What does that look like from a circadian sleep wakefulness standpoint?
You basically want to get as much light, ideally sunlight, but as much light into your eyes during the period of each 24 hour cycle when you want to be awake, when you want to be alert. And you want to get as little light into your eyes at the times of that 24 hour cycle when you want to be asleep or drowsy and falling asleep. How much is enough?
Well, a good number to shoot for as a rule of thumb is to try and get exposure to at least 100,000 lux before 9 a.m. 10 a.m. maybe, but before 9 a.m. Assuming you're waking up sometime between 5 and 8 a.m. The mechanism of circadian clock setting involves these neurons in your eye that send electrical signals to this clock above the roof of your mouth.
