Do This for 10 Minutes Instead and Wake Up With More Energy | Dr. Andrew Huberman
In a Nutshell
The core message is that feeling safe and accepted is the brain's foundation, and it comes from creating predictability through consistent daily protocols like morning sunlight, fixed meal times, and evening wind-down routines. When basic needs are met, the nervous system stops scanning for threats and frees mental energy for creativity and relationships. The second key takeaway is that deliberate discomfort—especially cold exposure done when you strongly resist it—grows the anterior mid-cingulate cortex, the brain area tied to tenacity and preserved cognition with age, while practices like Yoga Nidra restore dopamine and shift you from "thinking and doing" to "being and feeling."

The brain circuitry responsible for feelings of social connectedness is deeply rooted in our need for safety. Humans need two fundamental things: the feeling of safety and acceptance. The four words borrowed from Martha Beck—peace, contentment, fulfillment, and belonging—are critical to what people want and need at an aspirational level.
The nervous system includes hardwired genetic programs written into all human genomes regardless of color or background. These programs control automatic functions like breathing, digestion, and heart rate regulation, as well as bonding with caretakers during early infancy and evaluating safety and acceptance from other members of the species.
Brain circuits connected to the hypothalamus, which sits above the roof of the mouth, contain dense collections of neurons called nuclei responsible for temperature regulation, feeding, reproductive behavior, and other basic housekeeping functions. These areas are connected to brain regions that evaluate whether one is safe or not.
Safety is fundamentally about the ability to predict outcomes. The nervous system loves predictability, even when predictability arrives through hard things.
The major theme of the Huberman Lab podcast involves tools and protocols designed to anchor physiology in predictable states. Morning sunlight increases cortisol appropriately early in the day, sets a timer on melatonin secretion for later at night, helps with sleep, and creates a sense of predictability about alertness during waking hours.
Cold plunges, when done correctly, create discomfort but lead to increased catecholamines—dopamine, epinephrine, and norepinephrine—resulting in feeling more energized and slightly blissed out for the next two to four hours. This is a real neurochemical effect that has served this role for hundreds of thousands of years in humans.
Eating meals at consistent times (plus or minus an hour) creates hunger about 15 minutes before those meals, increasing predictability. This lends itself to safety and acceptance because it reduces the need to think about additional variables.
Basic protocols include viewing sunlight, taking walks after meals, getting evening sunlight, dimming lights in the evening, eating at consistent meal times, and consuming mostly unprocessed or minimally processed foods. These behaviors lead to feeling more alert, having more vitality during waking hours, and better sleep at night.
Protocols are optional and designed as a buffet—people should not feel obligated to do all of them. The protocols are meant to be woven into everyday life rather than becoming the center of family or relationships. They free up energy for creative pursuits, relationships, and friendships.
Ancient times had more predictability in some domains of life, such as living in small villages, but also had significant unpredictability—hunters or gatherers might not return from expeditions. The same neural circuits responsible for stress, lack of safety, and vigilance from ancient times remain active in modern brains.
Protocols function like stocking a refrigerator with ingredients—you may not know what you will cook, but having basic macronutrients covered provides more options. When basic needs are met, people can think about what they want to create rather than being forced into survival mode.
All animals, including humans, need to know where they are going to sleep. Dogs entering new environments immediately try to figure out their spot. This is about negotiating space—what is allowed and what is not. Children foraging an environment are trying to determine boundaries. Adults have the same fundamental need to orient in space and time.
The protocols bookend the extremely basic fundamental drives of the human brain for safety and acceptance with aspirational goals of connectedness, purpose, fulfillment, and peace. Discomfort often stems from feeling like things were not done correctly or that others did not do things right.
Repetitive thoughts often persist because no protocol has been built to address them. Creating a protocol for the most pressing concern—like knowing where you will sleep tonight—eliminates that specific thought and frees mental energy. The approach is to identify what is keeping someone up at night or causing the greatest anxiety and solve for that specific issue.
Physiology drives mental states, and emotional states drive physiology—this relationship is bidirectional. Emphasizing exhales during breathing tends to calm down the nervous system by making exhales longer and more intentional. Normally, inhales are active and exhales are passive. Deliberately emphasizing exhales slows heart rate through respiratory sinus arrhythmia, which links the heart, vagus nerve, diaphragm, and lungs.
Yoga nidra is a practice where the goal is to stay awake while deliberately relaxing the body. NSDR (non-sleep deep rest) is similar but removes intentions and involves less focus on chakras and other elements. A study from Denmark showed that people doing yoga nidra practice get a 60% increase in baseline dopamine levels in the basal ganglia, a brain area associated with preparation for movement and withholding of movement.
Yoga nidra restores mental and physical vigor by changing neurochemicals in the brain. The brain goes into pockets of sleep-like states during this practice, and it mimics rapid eye movement sleep where the brain is active but the body is completely still.
Yoga nidra moves people from thinking and doing to being and feeling. Thinking involves anticipating the future and is forebrain-dependent. Doing involves basal ganglia action generation and prefrontal cortical circuitry. Being and feeling shifts from exteroception—monitoring the external world—to interoception—monitoring the internal world within the confines of the skin.
Yoga nidra can be done for 10, 20, 30 minutes, or an hour. It reliably improves wakefulness, cognition, and vigor afterward. It restores dopamine levels in the basal ganglia, mimics rapid eye movement sleep, and helps people fall back asleep when needed. It also develops stronger autonomic regulation—the ability to take oneself out of stress states.
Yoga nidra has been used for managing physical pain during post-surgery recovery when thoughts of pain and stress were overwhelming. It helps with jet lag by removing anxious thoughts about sleep and work performance in new time zones. It works the first time and every time.
Mind active, body still is an unusual state outside of rapid eye movement sleep. Rick Rubin practices sitting with eyes closed and body still to generate ideas. Dr. Karl Deisseroth sits at a table or on a couch after his children go to sleep, stills his body completely, and forces himself to think in complete sentences for about an hour to structure ideas and generate new ones.
A method involves walking, then stopping to allow thoughts to continue as if in motion, with the mind active while the body remains still, then repeating. This creates an unusual state of mind with real value. Rapid eye movement sleep and associated dreams are where novel solutions to hard daytime problems are worked out.
The human brain is a magnificent machine and organ with limitations that can take people only up to a certain point. Understanding these limitations allows reliance on healthy collective thinking to overcome divides. Exiting individual brain and group think enables real solutions beyond compromise and conflict. Understanding the limits of cognition and how emotion drives cognition allows evolution of beliefs about what's possible.
The neural architecture called the brain is limited in seeing into the future and making the best decisions for everybody. No single individual can solve problems for everyone.
A collection of studies on the anterior mid-cingulate cortex represents one of the most important discoveries in the last 100 years of neuroscience. Most people, including many neuroscientists, have never heard of this brain area. Neurosurgeons know its location, but most neuroscientists don't know where it is unless they teach neuroanatomy.
Joe Parvizi at Stanford School of Medicine conducted a study during neurosurgery, stimulating different brain areas to find the surgical location. He discovered that stimulating the anterior mid-cingulate cortex caused awake patients to report feeling conflict pressing on them. One patient described it as "I feel like I'm driving into a storm, but I feel ready. I can do this." Others reported feeling challenged but capable, with a forward center of mass.
The anterior mid-cingulate cortex is associated with the feeling of tenacity and willpower to push through. People who take on new challenging practices see their anterior mid-cingulate cortex grow in volume, while those who fail to engage in regular challenging activity don't see the same increase. This brain structure is heavily interconnected with the dopamine reward system and serves as a hub for many inputs and outputs.
The anterior mid-cingulate cortex preserves its size and even grows in superagers - people who maintain cognition later into life without normal age-related decline separate from Alzheimer's type dementia. Superagers overcome typical working memory decline that occurs with aging.
The combination of willpower, taking on new things, learning, neuroplasticity, and lifespan may represent what is thought of as the will to live, associated with intense curiosity and desire to bring in new ideas and modes of thinking. New ideas and modes of thinking feed back on feelings of gaining internal reward, with dopamine as the universal currency of reward.
Everybody can become a better human being by taking on challenges. A challenge that grows the anterior mid-cingulate cortex is one that you don't want to engage in. If you love running or resistance training, these activities won't produce the effect. Meditation done when you don't want to do it enhances activation of the anterior mid-cingulate cortex. The key is pushing through resistance rather than just doing hard things.
Cold exposure serves as the universal stressful stimulus. The protocol involves asking yourself right before getting in cold water, on a scale of 1 to 10, how badly you don't want to get in. If the answer is 5-10, this represents a wall to get over. The desire to get out represents the second wall.
The walls are waves of adrenaline being released. Count walls rather than focusing on temperature or duration. Getting in for 15-20 seconds when you really don't want to accomplishes meaningful work for the anterior mid-cingulate cortex and adrenaline release system.
The cold plunge experience translates to real life by recognizing walls of adrenaline in hard conversations. Rather than making yourself so resilient that the adrenaline system doesn't work, learn to recognize the state of having adrenaline and staying calm. Noticing walls of adrenaline allows recognition that cognition shifts in adrenaline-filled states, and solutions available five minutes ago may not be accessible.
The goal is to sit in pain, regulate ourselves, rise to a place of peace, respond, and get together as the league of reasonable people. Cynicism never served anyone well and can be discarded while maintaining critical and discerning thinking. Cynicism is ego-fed negativity that implies superiority but usually comes from deep insecurity and separates people from others.
All people are believed capable of accessing the reasonable feature within themselves, though this requires a state of calm and feeling of safety.
