Andrew Huberman: My Exact Routine To Optimize Brain & Body, I Do All Of These Every Day!

Andrew Huberman and Steven Bartlett discuss science-backed daily protocols for optimizing health, focusing on hydration, sunlight exposure, exercise, stress reduction techniques, and sleep strategies. Each protocol supports specific neurobiological pathways and physiological systems, contributing to clarity, resilience, performance, and longevity.

Morning Hydration Boosts Brain Function and Cortisol For Clarity and Performance

Water and Electrolytes Upon Waking Enhance Cognitive Sharpness

Andrew Huberman emphasizes that the brain is significantly more sharp when properly hydrated. He recommends drinking 16 to 32 ounces of good, clean water upon waking, with the option to add electrolytes for extra benefit. The first protocol each morning is to hydrate immediately after waking, which not only replenishes fluids lost overnight but also stimulates an ascending pathway along the vagus nerve to wake up the brain. Hydration interacts with the body’s morning cortisol surge, helping to enhance cognitive clarity and readiness for the day.

Early Morning Hydration Aids 80-ounce Water Goal

Huberman recommends consuming about 80 ounces of water throughout the day. Drinking a substantial amount in the morning makes it more achievable without needing to front-load or back-load fluid intake in the evening, which could disrupt sleep.

Bright Light Exposure Aligns the Circadian Clock, Optimizing Cortisol Peaks For Healthy Sleep, Vision, and Metabolism

Sunlight or 10,000 Lux Light Post-Wake Activates Melanopsin Cells, Signals Circadian Clock

The second essential protocol is early exposure to daylight. Viewing natural sunlight—or on cloudy days, simply stepping into daylight—within the first hour of waking is critical. Exposure to sunlight activates melanopsin-containing intrinsically photosensitive ganglion cells in the eyes. These cells send signals, via axons, to the suprachiasmatic nucleus in the hypothalamus, which is the body's master circadian clock. Bright light in the morning helps spike cortisol in a healthy way, setting up low evening cortisol and boosting melatonin for sleep. Huberman notes, "You need this. You want this." If natural light is unavailable, a 10,000 lux artificial light can provide similar benefits and is also effective in offsetting symptoms of seasonal affective disorder.

Optimal Wavelengths in Low Solar Angle Sunlight Reduce Harmful Uv Exposure

Morning sunlight—when the solar angle is low—contains optimal red, orange, and yellow wavelengths with lower ultraviolet (UV) exposure. This makes it safer for your eyes and skin compared to overhead midday sun, which has a higher concentration of harmful UV rays. Being outdoors in morning light is optimal for informing the circadian clock and supporting metabolic, immune, and learning functions.

Morning Light Exposure Activates the Hpa Axis, Triggering a Higher Cortisol Peak Via a Neurological Window

Exposure to bright light in the first hour of the day powerfully activates the hypothalamic-pituitary-adrenal (HPA) axis, driving a healthy spike in cortisol. There is a “unique window” after waking in which this exposure has maximum effect, helping reduce stress reactivity throughout the day and supporting immune function.

Evening Light Prepares Eye and Brain Against Nighttime Screen Damage

Exposure to natural or bright light during the last third of the day serves as a "Netflix inoculation," buffering the eyes and brain against the negative impact of nighttime exposure to artificial blue light from screens. This can help protect melatonin production and minimize blood glucose disruptions due to evening screen time—though this protective effect does not seem to extend to adolescents.

Sunlight Penetrating Deep Improves Mitochondria, Glucose Tolerance, and Reduces Blood Sugar Spikes By 25%

Sunlight, particularly long-wavelength red and infrared light, penetrates deeply into the body—up to eight centimeters. This exposure boosts mitochondrial function, supports the release of stored melatonin as an antioxidant in cells, and improves glucose tolerance. Huberman cites research where red light exposure reduced post-glucose drink blood sugar spikes by more than 25%, showing direct metabolic benefits.

Daytime Light and Night Darkness Improve Health and Longevity Versus Inverted Exposure

Huberman cites studies indicating that bright daytime exposure combined with true darkness at night synergistically enhances health and longevity. Lack of bright daytime light and excess evening light exposure are linked to metabolic dysfunction, shortened lifespan, increased cancer risk, and sleep disruption. Even among smokers, those who get more sunlight live longer than non-smokers who don’t—illustrating sunlight's profound effect on health.

Early Morning Exercise Boosts Cortisol, Enhances Focus, and Supports Metabolic Health

Early Resistance or Cardio Exercise Enhances Cortisol and Hormonal Patterns

Exercising within three to four hours of waking delivers significant benefits. Morning resistance or cardiovascular exercise synchronizes with the natural cortisol rhythm, providing a healthy spike in the hormone that facilitates alertness and readiness for learning. Morning exercise improves focus for several hours, primes the brain for learning new information, and enhances metabolic and immune system function. While afternoon or evening exercise is also beneficial, the pronounced cortisol spike from morning exercise is uniquely advantageous.

Optimal Structure: Three Near-Failure Resistance Training Days, Three Varied-Intensity Cardio Days, and Rest Days For Recovery

Huberman recommends a weekly structure: alternate three resistance training sessions (with sets near failure and a focus on compound movements) with three cardio sessions (including one long slow, one moderate, and one high-intensity interval training). Allow at least one rest day, ideally after a heavy leg or taxing session. This routine is balanced for strength, endurance, and overall health rather than maximal muscle gain or marathon-level endurance.

Cold Exposure: Minimal Cortisol, High Adrenaline & [restricted term] for Better Stress Resilience

Contrary to popular belief, deliberate cold exposure does not significantly raise cortisol. Instead, it results in large increases in adrenaline, [restricted term], and [restricted term]—neurochemicals that promote alertness and stress resilience. This makes cold exposure a potent tool for enhancing daily focus and mood.

Andrew Huberman provides an in-depth exploration of the interconnections between circadian rhythms, cortisol, and other key hormones, highlighting their profound impact on clarity, resilience, readiness, and overall health.

Cortisol Curve: Foundation of Clarity, Resilience; High Morning Levels Enable Low Evening Levels

Huberman explains that the body's awakening process is driven by a cortisol spike known as the cortisol awakening response. This peak, ideally rising within the first 60 minutes of waking, acts as an internal alarm clock and is highly trainable to external stimuli, such as morning sunlight. Contrary to popular belief, high cortisol in the early day is desirable; it elevates mood, focus, attention, and the ability to learn. Huberman warns that many people have too low a morning cortisol peak and too high afternoon and evening levels—a pattern linked with disrupted sleep, worse metabolic health, and extended stress responses.

Cortisol follows a healthy daily curve: a pronounced peak in the morning, followed by a steady decline toward evening, allowing melatonin to rise and facilitate sleep. Huberman emphasizes that this morning peak is crucial because it establishes the low nighttime trough. If morning cortisol is insufficient, the evening baseline remains abnormally high, reducing the effectiveness of melatonin and impairing sleep quality. The flattening of this cortisol curve—marked by a blunted morning spike and persistently elevated evening/nighttime levels—is associated with shortened lifespan, poorer illness recovery, metabolic dysfunction, and increased cancer risk.

Exposure to screen light at night disrupts cortisol and melatonin patterns. Even if falling asleep is possible after evening screen use, negative effects on blood glucose and reduced morning cortisol levels often follow. Huberman notes that interventions like eating starches in the evening can help lower nighttime cortisol, supporting sleep onset.

Integrated Circadian System: Behaviors Synchronize Through Shared Circuits and Pathways

The circadian system integrates multiple behaviors via interconnected neural circuits. The timing of activities such as eating, exercise, light exposure, and sleep synchronizes the body's master clock in the brain with peripheral clocks throughout the body. Regular meal timing leads to anticipatory hormone (ghrelin) release, signaling upcoming food and reinforcing clock alignment. Exercising at the same time daily creates a similar anticipatory response, boosting energy and readiness. Huberman observes that the body starts preparing before these activities through familiar routines, illustrating the power of behavioral consistency for optimal readiness and performance.

Protocols across sleep, food, and exercise have synergistic effects. Quality of sleep one night predicts cognitive and physical performance the next day, demonstrating how these “gears” of the circadian system move in concert. Instead of relying solely on supplements or medications, optimizing sleep, activity, food, and light exposure provides the greatest benefits for hormonal health and well-being.

The conversation between Steven Bartlett and Andrew Huberman explores neurobiological mechanisms and practical training methods for enhancing stress resilience and thoughtful behavior, especially under pressure.

Anterior Mid-cingulate Cortex: Tenacity Muscle Growing With Voluntary Discomfort Exposure, Enhancing Difficulty Handling Capacity

Andrew Huberman explains that the anterior mid-cingulate cortex is a key brain region acting as a "tenacity muscle"—crucial for willpower and persistence. This structure lights up whenever a person faces social, physical, or situational pressure and chooses to push through internal or external resistance. The level of activation is proportional to the difficulty of the challenge faced, collecting and processing real-time information about the nature and intensity of pressure encountered.

When individuals deliberately engage in activities that generate internal resistance or discomfort—such as learning a new language, starting an exercise routine, dancing despite personal embarrassment, or completing unpleasant tasks—the anterior mid-cingulate cortex undergoes neuroplasticity. This means the region strengthens and expands, better equipping people to handle greater challenges in the future. Bartlett reflects that this understanding reframed hard experiences for him, seeing each as a neurological investment, much like physical exercise builds muscle for future physical exertion.

Research shows that those who successfully diet, start exercising, or embark on unfamiliar or unenjoyable endeavors often exhibit a larger and more active anterior mid-cingulate cortex. This adaptation makes them more likely to stick with difficult changes, persist with habits, and perform well in demanding tasks later. Huberman emphasizes that this is not about enduring unnecessary pain but about developing safety and self-protection systems through managing alertness and awareness, allowing for improved detection of subtle social and emotional cues.

Cold Exposure Trains the Nervous System to Maintain Prefrontal Cortex Function and Decision-Making Under Maximal Arousal

Huberman highlights cold water immersion—a specific voluntary discomfort—as a powerful training method. During the first 20-30 seconds of cold exposure, prefrontal cortex function, which governs strategic thinking and self-control, is sharply suppressed. The sudden rush of adrenaline and [restricted term] simulates acute high-arousal stress, temporarily making logical thinking and impulse control harder, as if the brain is briefly “damaged.” Practicing calmness, breathing, and cognitive control in this state trains the nervous system for real-world stress: logic and thoughtful decisions become more accessible even under intense emotional arousal or adrenaline spikes.

The benefit from cold exposure is transferable. People who train to remain composed during this physiological onslaught learn to maintain prefrontal cortex engagement—leading to better real-time decisions in unforeseen stressful situations. As Huberman notes, this ability to keep one’s head clear when flooded by adrenaline has critical advantages not just in emergencies but in everyday impulse control.

He points out that the initial cognitive suppression during cold exposure is mirrored in many stressful moments—remaining silent or pausing for 20-30 seconds during such situations allows the prefrontal cortex to come back online, helping to avoid rash decisions or regrettable actions. This tactic—waiting for the brain’s cognitive center to re-engage—provides a functional protocol for handling real-life stress.

Andrew Huberman and Steven Bartlett explore effective, accessible supplement protocols, the promise and risks of peptide therapies, and the necessity of robust behavioral foundations for any supplemental or pharmacological intervention.

Supplement Protocol: Omega-3, Vitamin D, Magnesium, Stimulants to Address Deficiencies and Cognitive Limitations At Minimal Cost and Risk

Huberman outlines a practical, cost-conscious approach to supplementation for sustained mental and physical health.

Prescription EPA Omega-3 ([restricted term]) Promotes Mental and Cardiovascular Health, Cleared Of Heavy Metals

Huberman emphasizes the importance of at least 1 gram per day of EPA omega-3, particularly the prescription version, [restricted term], now available in generic and inexpensive form. Unlike many over-the-counter fish oil supplements, [restricted term] is purified and free of heavy metals, significantly reducing the risk of mercury poisoning. EPA omega-3 offers strong benefits for both brain and cardiovascular health and reduced inflammation. Huberman recommends advocating for a doctor’s prescription for [restricted term], especially for those who don’t regularly eat fatty fish.

High-Dose Vitamin D (5,000-10,000 IU) Enhances Hormone Health and Metabolic Markers

He recommends a higher-than-standard daily dose of vitamin D, typically between 5,000 and 10,000 IU, arguing that most people underdose. Regular vitamin D supplementation at these levels supports hormone health and improved blood metabolic markers, beyond merely meeting the recommended dietary allowance. While some caution against over-supplementation, Huberman advocates regular blood tests to avoid excessive dosing.

Magnesium Threonate or Bisglycinate: Enhances Sleep and Cognitive Function, Threonate Crosses Blood-Brain Barrier

For those experiencing poor sleep, Huberman suggests magnesium threonate or bisglycinate. Both forms are effective for sleep support. Magnesium threonate is especially noted for its capacity to cross the blood-brain barrier, possibly offering additional cognitive benefits.

Alpha-GPC Boosts Acetylcholine For Focus, Flexibility, REM Sleep; Garlic Reduces TMAO Cardiovascular Risk

Huberman is a proponent of alpha-GPC, usually at 600–900 mg, to boost brain acetylcholine—a key neurotransmitter for focus, mental flexibility, and REM sleep. Unlike prescription stimulants, alpha-GPC can enhance focus without harming sleep quality and may even improve REM sleep duration. However, alpha-GPC increases TMAO, a compound associated with cardiovascular risk. Taking 600 mg of odorless garlic as a supplement alongside alpha-GPC may help reduce TMAO levels and mitigate this risk.

Peptide Therapies Promising, but Require Medical Supervision and Awareness of Unknown Long-Term Effects

Huberman addresses the expanding landscape of peptide therapies, including weight-loss agents, repair peptides, and pineal-supporting compounds, all of which require careful medical oversight and a realistic assessment of long-term safety.

GLP-1 Agonists (Semaglutide, Tirzepatide, Retatrutide) Aid Weight Loss, Metabolic Health in Obesity; Eye Abnormalities May Raise Glaucoma Risk, Warranting Vision Monitoring

GLP-1 drugs—such as semaglutide, tirzepatide, and retatrutide—are transforming obesity management by mimicking the glucagon-like peptide hormone that suppresses appetite and may lower inflammation. Huberman points to data showing one-third body weight loss within a year in some clinical trials. However, he stresses these drugs dramatically raise GLP-1 levels beyond natural human exposure and may reduce cravings for alcohol and sugar.

A major safety concern involves possible vision loss for those with certain structural eye abnormalities. Huberman clarifies that although some reports of increased blindness tied to GLP-1 drugs may be overstated, individuals should get their eyes scanned, specifically checking optic nerve head structure and intraocular pressure, to screen for risk factors before starting therapy.

GLP-1 Microdosing: Cost-Effective Symptom Relief With Fewer Side Effects for Chronic Conditions

Huberman notes a growing trend toward microdosing GLP-1 agonists, with users taking very small doses (e.g., once every ten days) to reduce medication side effects and lower costs, though robust clinical trials on this approach are lacking.

BPC-157 May Accelerate Injury Recovery, but Lacks Clinical Trials, and Potential Tumor Vascularization Is a Safety Concern

BPC-157 is an endogenous peptide increasingly used for soft tissue and nerve injury recovery. Animal studies and user reports suggest accelerated healing, but there is a risk of unwanted blood vessel formation that could, in theory, promote tumor development. Clinical trials in humans ...

Sustainable Development Requires Balancing External Roles With Authentic Desires and Core Identity

Andrew Huberman draws from the advice of James Hollis, an 84-year-old Jungian analyst, who proposes a daily life framework: "shut up," "suit up," and "show up." "Shut up" advises adopting a gratitude practice—acknowledging that there are always those who suffer more and recognizing the good things in life. It encompasses both giving and receiving gratitude, with Huberman highlighting the importance of allowing oneself to genuinely receive acknowledgment.

"Suit up" refers to preparation and self-care: waking up, maintaining health, getting organized, and ensuring readiness for various roles—whether as a student, professional, or family member. This means not just physical grooming but also investing in the skills and discipline needed to meet daily challenges effectively.

"Show up" is about fulfilling one’s roles in the world, acknowledging that no person is exempt from responsibilities. One must take on and enact various outward roles—be it parent, teacher, engineer, or podcaster—and everyone must contribute.

However, Huberman notes that orienting life exclusively around these structured roles and routines, no matter how diligently performed, can ultimately lead to misery if done in isolation from personal meaning. Hollis recommends that, at least once a day, a person should step outside this realm of achievement and role fulfillment—exiting the "stimulus-response mode"—to engage in activities without goals, such as meditation, drawing, or music. In these moments, the unconscious mind may surface one’s deepest desires through emotions or analogies, offering guidance for authentic living. This is how people receive feedback from their inner world, connecting external responsibilities with internal truth.

Callings and Purpose Emerge Through Exploration Over Introspection or Waiting

Huberman addresses a frequent question on how to find one’s calling, emphasizing that discovery comes through engagement, not isolated reflection. He argues that true purpose is rarely found by sitting and waiting for insight or endlessly analyzing oneself. Instead, meaning emerges through action—often while doing other jobs that one finds unsatisfying. As a person tries different roles, they gradually shift toward what engages them more deeply, moving stepwise from activities they hate to those they tolerate, and finally to those that resonate with their core self.

He advocates for pragmatic life planning using five-year cycles, shaped by personal experience in academia and beyond. Each cycle allows for carrying forward valuable practices—like exercise, faith, or hydration—while permitting uncertainty about the distant future. Huberman sees no need for a single fixed purpose; instead, each stage of life can build upon the last, accommodating new insights and changes in direction.

Faith and Spirituality Provide Meaning and Psychological Benefits Beyond Neuroscience and Logic, Aiding Anxiety Management and Life Direction

Huberman describes personally embracing faith and the belief in powers beyond human understanding after years of skepticism and private spirituality. He reports that doing so brought profound relief, lessening the burden of needing to control every internal and external circumstance. Faith, for him, acts like a set of "emotional infrared goggles," providing a perspective on existence that pure logic cannot access.

For the past several years, he has adopted a nightly prayer practice, praying before sleep and anytime he wakes at night. He describes prayer not as a way of outsourcing solutions, but as asking for the energy, humility, and clarity to act rightly and to serve others. He notes observable benefits: reduced anxiety, enhanced emotion regulation, and a sense of synchronistic guidance—experiencing what he describes as "miracles," where answers appeared through unexpected channels following prayer.

Neuroscience research also supports a neurological basis for spiritual experience. Huberman references studies showing that stimulating particular brain regions can give rise to feelings of transcendence and encounters with divinity. He compares the existence of brain areas for thirst as evidence of the existence of water, suggesting that a neural appetite for spiritual experience points towards a real phenomenon, if not a mechanistic proof.

He finds it psychologically freeing and enriching to embrace faith alongside his scientific pursuits. Prayer, he observes, enables him to surrender ov ...
