Essentials: Time Perception, Memory & Focus

In this Huberman Lab Essentials episode, I explore how biological rhythms and neurochemicals impact our perception of time. I describe how the body aligns with daily and seasonal light cycles to regulate hormones that influence energy, mood and motivation throughout the year. I share science-based tools to enhance focus and productivity, including strategies for structuring work intervals and optimizing the timing of exercise and daily light exposure. I also explain how neurotransmitters like dopamine and serotonin influence our perception of time and how factors such as novelty, emotion and routine impact how we experience and recall time.

My guest is DJ Shipley, a retired Tier 1 operator Navy SEAL and now a top public educator on how to build mental and physical health and reach top-level performance in any endeavor. DJ’s life is one marked by extraordinary strivings, wins, setbacks and comebacks that together have shaped his approach to overcoming challenges of all kinds and to daily life. DJ explains a regimen of clear, practical steps and a mental stance that can allow anyone—male, female, young or old—to build extreme resilience of mind and body and to be successful in family and work. We also discuss his experience with new, emerging treatments for addiction, PTSD and depression that many people, not just veterans, are benefiting from. The tools DJ describes to “stack small wins” and to be ultra-intentional about your mindset will be of immense benefit to anyone wishing to achieve the best version of themselves.

My guest is Dr. Bret Contreras, PhD, CSCS, a world-renowned expert on muscle and strength building for women and for men. Bret is known as “the glute guy” for his expertise in helping people build their ideal physique, including how to grow and/or strengthen their gluteus muscles. He explains how to resistance train to improve strength, hypertrophy and aesthetics, and to overcome genetically or injury-induced weaker body parts. We cover ideal training frequency, exercise selection, sets and repetitions and periodization. Our discussion is for women and men of any age and experience level seeking to maximize their aesthetics, performance and longevity. Read the episode show notes at hubermanlab.com.

My guest is Dr. Christof Koch, PhD, a pioneering researcher on the topic of consciousness, an investigator at the Allen Institute for Brain Science and the chief scientist at the Tiny Blue Dot Foundation. We discuss the neuroscience of consciousness—how it arises in our brain, how it shapes our identity and how we can modify and expand it. Dr. Koch explains how we all experience life through a unique “perception box,” which holds our beliefs, our memories and thus our biases about reality. We discuss how human consciousness is changed by meditation, non-sleep deep rest, psychedelics, dreams and virtual reality. We also discuss neuroplasticity (rewiring the brain), flow states and the ever-changing but also persistent aspect of the “collective consciousness” of humanity.

In this Huberman Lab Essentials episode, I discuss science-supported nutrients that directly support brain structure, function and long-term cognitive health. I highlight specific nutrients, including omega-3 fatty acids, creatine, phosphatidylserine, anthocyanins, choline and glutamine, and discuss their recommended doses and dietary sources. I also describe how taste perception, gut-brain signaling and learned associations shape what foods we prefer and crave. Finally, I share practical behavioral tools to help rewire your food preferences toward healthier choices. Read the episode show notes at hubermanlab.com.
