What is the importance of sleep discussed in this episode?
Welcome to the Huberman Lab guest series, where I and an expert guest discuss science and science-based tools for everyday life. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today's episode marks the first in our six-episode series all about sleep. Our expert guest for this series is Dr. Matthew Walker, professor of neuroscience and psychology and the director of the Center for Sleep Science at the University of California, Berkeley. He is also the author of the bestselling book, Why We Sleep. During the course of the six-episode series, for which we release one episode per week starting with this episode one, we cover essentially all aspects of sleep and provide numerous practical tools to improve your sleep.
What are the different stages of sleep and their significance?
For instance, we discuss the biology of sleep, including the different sleep stages, as well as why sleep is so important for our mental and physical health. We also talk about how sleep regulates things like emotionality and learning and neuroplasticity, that is your brain's ability to change in response to experience. And we discuss the various things that you can do to improve your sleep, everything from how to time lighting, temperature, exercise, eating, and the various things that can impact sleep both positively and negatively, such as alcohol. cannabis, and various supplements and drugs that have been shown to improve sleep.
How does sleep affect our hormones and immune system?
We also talk about naps, dreaming and the role of dreams, and lucid dreaming, which is when you dream and you are aware that you are dreaming. In today's episode one, we specifically focus on why sleep is so important and what happens when we do not get enough sleep or enough quality sleep. We also talk about the various sleep stages, and we also talk about a very specific formula that everyone should know for themselves called QQRT, which is an acronym that stands for quality, quantity, regularity, and timing of sleep. Four factors, which today you'll learn how to identify specifically for you what your optimal QQRT is, and then to apply that in order to get the best possible night's sleep, which of course equates to the best possible level of focus and alertness throughout your days.
Both Dr. Walker and I are very excited to share the material in this six-episode series with all of you. And as we march into today's episode one, I'm sure it will both provide a ton of excellent practical learning for all of you, as well as spark many questions that are sure to be answered in the subsequent episodes of this series. Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford.
What practical tools can improve sleep quality?
It is, however, part of my desire and effort to bring zero cost to consumer information about science and science-related tools to the general public. In keeping with that theme, I'd like to thank the sponsors of today's podcast. Our first sponsor is 8Sleep. 8Sleep makes smart mattress covers with cooling, heating, and sleep tracking capacity. Many times on this podcast, we discuss how in order to fall and stay deeply asleep, your body temperature actually needs to drop by about one to three degrees. And in order to wake up feeling maximally refreshed and energized, your body temperature needs to heat up by about one to three degrees. Eight sleep makes it very easy to control the temperature of your sleeping environment so that it's easy to fall and stay asleep and wake up feeling refreshed.
I started sleeping on an eight sleep mattress cover several years ago, and it has completely and positively transformed my sleep. So much so that when I travel to hotels or Airbnbs, I really miss my eight sleep. I've even shipped my eight sleep out to hotels that I've been staying in because it improves my sleep that much. If you'd like to try 8sleep, you can go to 8sleep.com slash Huberman to save $150 off their Pod 3 cover. 8sleep currently ships to the USA, Canada, UK, select countries in the EU, and Australia. Again, that's 8sleep.com slash Huberman.
