Andrew Huberman's Daily Routine for Brain and Body

Andrew Huberman adheres to nearly all his health protocols daily, taking only one day off per week. He describes these protocols as interconnected gears, where consistency is crucial for their synergistic effects on the body. Most of these foundational protocols are either free or can be implemented within an existing budget, making them accessible to many.

High cortisol levels in the early part of the day are essential for maintaining an elevated mood, focus, and attention, and for enhancing learning capacity. This morning cortisol spike also helps establish naturally low cortisol levels in the afternoon and evening, which are necessary for falling and staying asleep. This cortisol curve is trainable and adapts to external stimulants, while a flattened curve has been linked to shorter lifespans.

Viewing sunlight within the first hour of waking is crucial for activating the HPA axis and triggering the release of adrenal cortisol. Sunlight is the optimal stimulus for melanopsin-containing cells in the eyes, which are vital for this hormonal response. Even on overcast days, natural daylight is effective, unlike screens, which are insufficient for morning cortisol spikes and can be disruptive at night.

Long-wavelength light, including red and infrared light, can penetrate the body up to 8 centimeters. This type of light exposure has been shown to improve metabolic health, with studies indicating a reduction in glucose spikes by over 25%. In contrast, indoor LED lights, which lack the full spectrum of natural light, may potentially damage mitochondria compared to natural light spectrums.

Photoreceptors in the eyes are among the most metabolically active cells in the body, and their function can decline with age. People over 40 who experience age-related vision loss may see improvements by exposing their eyes to long-wavelength light, specifically red or infrared. For this benefit to be effective, light exposure must occur within the first three hours of the day. This simple practice offers protective benefits only for individuals aged 40 and older.

Andrew Huberman suggests that anyone using artificial LED devices after 6:00 p.m. can be considered a 'night shift worker,' regardless of their formal employment. Research on night shift patterns correlates with shorter lifespans and increased metabolic illness due to disrupted circadian rhythms. He notes that late-day sunlight exposure can act as an 'inoculation' against the negative effects of evening screen light by helping to regulate the body's internal clock.

Contrary to a common misconception, deliberate cold exposure does not significantly raise cortisol levels. Instead, it causes a substantial increase in adrenaline, norepinephrine, and dopamine, which are beneficial for mood and alertness. Huberman emphasizes that appropriate psychological stressors, rather than cold exposure, are the primary drivers of cortisol fluctuations. He expressed surprise that some individuals who advocate for high-intensity exercise suggest cold exposure raises cortisol, asserting this is not true.

The anterior mid-cingulate cortex is identified as the brain's center for tenacity, responsible for the ability to push through internal or external resistance. This highly plastic structure grows and strengthens with consistent engagement in difficult tasks. Activities like successfully adhering to a diet or starting new exercise programs are shown to increase its size and activity, fostering a mindset of leaning into challenges.

During the initial 20 to 30 seconds of acute stress, the prefrontal cortex experiences suppression, leading to a temporary state of impaired executive function. Huberman describes this state as being 'brain damaged' in terms of rational thought, where individuals are more likely to react physically or instinctively. It is advisable to avoid making decisions or engaging in communication during this critical initial phase of stress.

Prioritizing convenience by exchanging time and effort can be neurologically detrimental. Andrew Huberman argues that optimal living involves embracing striving and struggle rather than constantly seeking comfort. The process of striving for improvement creates a sense of 'meaning,' which is a vital component of mental health and overall well-being. This perspective suggests that constant ease may undermine fundamental neurological processes necessary for resilience and personal growth.

Engaging in an intense weightlifting session or high-intensity interval training (HIIT) can prime the brain for enhanced learning in the four hours following the workout. Learning requires elevated levels of arousal, specifically driven by adrenaline and cortisol, which are naturally boosted by intense physical activity. This post-workout window creates an optimal period for improved cognitive task performance and information retention.

The 'physiological sigh,' involving a double inhale followed by a long exhale, is a powerful technique for resetting carbon dioxide levels and calming the brain. Discovered by Jack Feldman at UCLA, this method involves a second short inhale that helps to maximally inflate the millions of tiny air sacs in the lungs, opening any collapsed ones. The subsequent long exhale allows for the greatest offloading of carbon dioxide, which in turn triggers the parasympathetic nervous system via the vagus nerve, promoting relaxation.

Specific eye movement patterns can facilitate falling back asleep by temporarily shutting down proprioceptive circuits in the cerebellum. The cerebellum, often called the 'mini-brain,' is heavily involved in balance and proprioception—the body's sense of its position. By moving the eyes from side-to-side or in circular patterns, individuals can effectively 'forget' their limb position, which greatly speeds up the process of falling back asleep.

Andrew Huberman emphasizes that behavioral tools form the essential foundation for any health optimization strategy. He highlights the efficacy of peptides like pinealon for improving REM sleep and discusses GLP-1 drugs, which mimic extendin found in Gila monsters, representing an unprecedented thousand-fold increase in hormone levels. However, he strongly cautions that pharmacological interventions, no matter how potent, should only build upon a robust foundation of consistent behavioral protocols to ensure lasting benefits.

Drawing a philosophical analogy, Huberman suggests that the existence of thirst circuits in the brain for water implies the existence of water itself. Similarly, he posits that the human desire to understand life and what lies beyond it points to an objective reality. While acknowledging gaps in this reasoning, he finds it a useful framework for seeking meaning and understanding in life, implying that the very circuit for understanding signifies an objective truth to be understood.

Huberman utilizes prayer before his podcasts as a personal mechanism to remove ego and maintain humility. He states that his prayers focus on seeking clarity and ensuring that the information he shares is useful to others, rather than serving selfish gain. This practice helps him maintain an intention to serve and to propagate beneficial knowledge, fostering a selfless approach to his work.

While dimming lights at night is commonly associated with suppressing melatonin, Huberman points out a crucial additional reason: bright lights increase cortisol. Elevated cortisol levels at night interfere with sleep quality, making it harder to fall and stay asleep. Therefore, keeping the sleeping environment as dark as possible is essential not just for melatonin production but also for maintaining low cortisol levels, optimizing sleep.

Even if a phone is not actively being used, its mere presence in a room diminishes cognitive flexibility and requires more energy to focus. This occurs because the brain subconsciously anticipates potential notifications, creating a 'subscript' of distraction that consumes mental resources. Removing the phone from the room can significantly increase cognitive capacity, allowing for deeper and more focused work by eliminating this subtle background anticipation.

Huberman highlights research by Massud Hussein from Oxford showing that some patients exhibit the anatomical hallmarks of Alzheimer's dementia, such as plaques and tangles, but do not experience cognitive impairment or memory loss. This phenomenon suggests a potential separation between the physical pathology of Alzheimer's and its cognitive symptoms. Key factors in this protection include consistent physical exercise and avid engagement in learning and mental activities, which help preserve brain function despite underlying disease markers.

The brain's glymphatic system clears waste products primarily during sleep, but new research suggests that certain meditative states can also activate this clearance. A recent study indicates that a short period of meditation can increase glymphatic clearance during the daytime. Huberman explains that regular meditators may be able to reduce their sleep requirement by an hour, by engaging in about 20 minutes of daily meditation, as it provides a daytime boost in waste removal. Additionally, sleeping on one's side with the head slightly elevated may also enhance glymphatic function.

Huberman recommends several daily health protocols for optimizing brain and body function. For brain and cardiovascular health, he suggests prescription-grade Omega-3 (EPA), specifically Lovaza, which is now generically available and affordable. He also advises Vitamin D supplementation, ranging from 5,000 to 10,000 IU per day, to support hormone health. For enhanced focus, Alpha-GPC (600–900mg) is recommended, alongside garlic supplementation to mitigate any potential cardiovascular risks associated with Alpha-GPC.

Walking after meals offers significant metabolic benefits, particularly in buffering blood glucose spikes. The low-level, repeated muscle contractions involved in walking effectively help manage glucose levels. The soleus muscle, located in the calf, plays an especially critical role in glucose utilization. Incorporating a post-meal walk can prevent energy crashes and contributes positively to overall metabolic health by improving the body's ability to process carbohydrates.
