This is episode 6 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley and a leading public educator on sleep for mental and physical health, learning and human performance. In this episode, we discuss dreaming, including the biological mechanism of dreams, what dreams mean and their role in daytime life. 
We explore how dreams can enhance our creativity and emotional well-being and help us resolve various challenges and dilemmas. We discuss how to remember and interpret your dreams and the abstractions/symbols frequently present in dreams.
We also discuss nightmares and therapies to treat reoccurring nightmares. We explain what lucid dreaming is and if there are benefits or drawbacks to this type of dreaming.
Dr. Walker also answers frequently asked audience questions and discusses snoring, body position, sleep supplements, sleep challenges due to aging, menopause, stopping racing thoughts, and how to fall back asleep if you wake in the middle of the night.

In this episode, my guest is Dr. Casey Means, M.D., a physician trained at Stanford University School of Medicine, an expert on metabolic health and the author of the book, "Good Energy." We discuss how to leverage nutrition, exercise and environmental factors to enhance your metabolic health by improving mitochondrial function, hormone and blood sugar regulation. 
We also explore how fasting, deliberate cold exposure and spending time in nature can impact metabolic health, how to control food cravings and how to assess your metabolic health using blood testing, continuous glucose monitors and other tools. 
Metabolic dysfunction is a leading cause of chronic disease, obesity and reduced lifespan around the world. Conversely, improving your mitochondrial and metabolic health can positively affect your health span and longevity.
Listeners of this episode will learn low- and zero-cost tools to improve their metabolic health, physical and mental well-being, body composition and target the root cause of various common diseases.

This is episode 5 of our 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley and the host of The Matt Walker Podcast. In this episode, we explain the connection between sleep and mood, emotional regulation and mental well-being. 
We explain the role of rapid eye movement (REM) sleep in processing emotions and emotional memories and why sleep deprivation causes agitation, impulsivity and emotional reactivity. 
We also discuss why sleep disruption is a hallmark feature of PTSD, anxiety, depression, suicidality, and other psychiatric conditions. 
We explain protocols for improving REM sleep and other sleep phases in order to harness the therapeutic power of quality sleep to feel calmer and emotionally restored.
This episode describes various actionable tools to improve sleep for those struggling with mental health or mood and those wanting to bolster their overall state and well-being. 
The next episode in this special series explores dreams, including lucid dreaming, nightmares and dream interpretation.

Welcome to a preview of the 17th Ask Me Anything (AMA) episode, part of Huberman Lab Premium.
Huberman Lab Premium was launched for two main reasons. First, it was launched in order to raise support for the main Huberman Lab podcast — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation. Read our Annual Letter 2023.
If you're an existing Premium member, you can login to access the full episode.
If you're not a member, you can join Huberman Lab Premium to enjoy exclusive content, including monthly Ask Me Anything (AMA) episodes, AMA transcripts, podcast episode transcripts, early access to live events and help advance human scientific research.

In this episode, I explain how to strengthen and build a stable, pain-free back and how to reduce or eliminate existing back pain. I explain the anatomy and physiology of the spinal cord and vertebrae, intervertebral disks and nerve pathways, and the abdominal and back muscles that together can be leveraged to stabilize the back. 
Then, I describe protocols: “McGill’s Big 3” exercises, a highly effective psoas stretch, abdominal stabilization, breathing techniques, and protocols to reinforce essential supports for the back, including the neck, pelvis, feet, and toes. 
I also explain how you can reduce and potentially eliminate back pain and sciatica using a specific type of bar hang, “cobra push-ups,” medial-glute strengthening exercises, and more. 
Back pain greatly impedes one’s ability to enjoy daily activities; this episode provides zero-cost, minimal time-investment protocols to improve your back strength and stability and allow you to move through life pain-free and with ease and mobility.

This is episode 4 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley, and author of the best-selling book "Why We Sleep." In this episode, we discuss the relationship between sleep, learning and creativity. 
We explain why and how sleep before and after a learning bout can improve memory and performance for both cognitive tasks and physical skills. We also discuss how to use time learning and sleep, how to use naps, non-sleep deep rest states, and caffeine to optimize learning, and the mechanisms for sleep and memory consolidation. 
We also explain the critical role that sleep plays in creativity and one's ability to discover novel solutions to challenges and problems. 
This episode is filled with actionable information on using sleep to enhance skill learning and improve memory and creativity. 
The next episode in this guest series explains how sleep benefits emotional regulation and mental health.
