Andrew Huberman on Building a Sustainable Routine for Focus and Health

Andrew Huberman tells a16z's Daisy Wolf that taking work seriously means organizing the day around it. In a conversation about his routines, he describes the habits he prioritizes, the distractions he struggles with, and the need to make intense work sustainable.

Wolf asks when he realized listeners were changing their lives because of his podcast. Huberman says he did not anticipate its reach. He's pleased that people are acting on health information, but stresses that most of the protocols he discusses come from other researchers' work.

Wolf mentions that Marc Andreessen stopped drinking after listening to him. Huberman says Andreessen decided that abstaining was easier than setting a limit. He distinguishes that personal choice from enjoying an occasional drink and describes his own reading of the health data.

Huberman says he enjoys reading papers, trying ideas and explaining what he learns. Talking about other scientists' work gives him freedom to explore, though it also means taking care to represent their research accurately.

Asked to reconstruct the previous day, Huberman starts with waking up groggy, using the bathroom and keeping his phone outside the bedroom. He says his mind is as disorganized as anyone's when he wakes.

His first deliberate practice is five minutes of breathing meditation. He used to think meditation meant becoming peaceful; now he describes its value as noticing the chaos of thought without immediately acting on it.

He compares that observation to the difficult final repetitions of a workout: the challenge itself can be part of the practice. He feels it helps him recognize which thoughts deserve attention as he moves into the day.

Next comes morning light and water, sometimes during a walk or on the roof. If he wakes before sunrise, he uses a bright artificial light. On exercise mornings, he says, he drinks caffeine immediately rather than waiting; yerba mate is his preferred source.

Huberman describes a routine he says he has followed for 35 years: three days of resistance training and two or three cardio sessions. He emphasizes choosing activities that feel right and can be performed safely, rather than joining someone else's workout out of pressure.

For one short cardio session, he warms up and alternates 20 seconds of hard effort with 10 seconds of rest eight times. Other sessions might be a long hike, sometimes with a weighted pack, and, when sleep and recovery allow, a shorter run.

His first resistance session is leg day, which takes about an hour and is the hardest of the week. He follows it with at least a day off, sometimes more depending on recovery, and may use sauna and cold exposure.

The next session combines pushing and pulling exercises for the torso. A third focuses on smaller muscle groups such as arms, calves and abdominals. He says the order can start on any day; recovery determines how he spaces the workouts.

For a movement, he describes a light set, a moderate preparation set and then two hard work sets with several minutes of rest. He aims for momentary muscular failure while maintaining form, records the work and tries to progress over time.

He says the lower volume lets him put more effort into individual sets without leaving him crushed. He offers an anecdote about an athlete surprised by the results, and says the important measure for him is whether the routine remains effective and enjoyable.

After the leg workout, he ate fruit, whey protein, oatmeal and sourdough toast with butter. Later he had steak, cucumbers, tomatoes, rice and olive oil. On training days he tends to eat more at dinner than on days without exercise.

Huberman encourages finding nutritious foods that also agree with one's digestion. Broccoli, for example, does not sit well with him. He suggests experimenting with individual ingredients to learn what works, rather than assuming the same menu suits everyone.

He says he is less interested in sweets than in fats and enjoys Parmesan, steak and particular styles of pizza. He also likes croissants. He has found that being extremely strict about eating does not necessarily make him stronger or happier.

When he has not slept enough, Huberman uses a 10- to 30-minute yoga nidra or non-sleep deep rest session in the afternoon. He describes lying still, relaxing the body and keeping the mind awake, and says he often comes out feeling restored and clearer about what to do next.

He jokes about Andreessen calling the practice a nap. Huberman considers it different because he aims to remain awake, and discusses emerging research into states between waking and sleep. He presents these as areas of interest rather than settled personal results.

Later in the day he tries to walk or step outside before sunset. He recalls staff at a Stanford sleep lab doing this when he was a student, before the underlying light-sensitive retinal cells were identified, and says the experience shaped his routine.

He generally stops caffeine around 2 p.m. because later caffeine interferes with his sleep. Dinner usually ends around 7:30 or 8, though he says he is not rigid about it; in the last hour before bed he dims the lights and puts away the phone.

Wolf asks about blue-light glasses. Huberman says sensitivity to evening light varies and that his own sleep suffers when he is exposed to bright overhead light at night. He dims the lights or wears red lenses, while acknowledging that the reasons for individual differences are not fully understood.

They discuss light exposure at different times of day. Huberman says he looks at the UV index and prefers morning or late-afternoon outdoor light; his comments describe his practice and his interpretation of the science.

Asked about supplements, Huberman lists the products he personally takes and notes commercial relationships: AG1 sponsors his podcast, and he helped create a sleep supplement. He describes using AG1 as a nutritional backstop, along with fish oil and vitamin D.

He says he uses prescription omega-3 medication to reach his preferred EPA intake and also describes taking tongkat ali and a form of vitamin B6, based in part on his own blood work. These are accounts of his regimen, not evidence that the same choices fit other people.

Huberman also takes N-acetylcysteine and recounts research he believes suggests a possible benefit against flu. He is uncertain about the study's exact figures and says they need checking; he increases his own use when traveling or feeling run down.

At lunch he takes a multivitamin and digestive enzymes. He says an enzyme suggested by a colleague changed how he tolerates some foods, but explicitly distinguishes that personal experience from a clinical study.

He mentions desiccated liver and cautions that it contains iron. In the evening he uses a sleep supplement he helped formulate. He also notes that he has experimented with hormones and peptides, while setting that separate discussion aside.

Wolf asks which of his own recommendations is hardest to follow. Huberman points to social media: X and Instagram now live on a separate phone, which he places in a timed lockbox after a designated period of use.

He finds the platforms absorbing and says responding to what people say about him can consume time. Although he feels some embarrassment about needing a lockbox, he finds physical inaccessibility helps him reclaim attention.

Huberman refers to research suggesting that a nearby phone can draw on cognitive resources even when people maintain their focus. For him, putting the phone in another room helps, and locking it away creates a stronger boundary.

When Wolf asks for only three health priorities, he chooses bright morning light, resistance training and making the sleep one can get as good as possible. He acknowledges that children, work, noise and travel can make a perfect sleep schedule unrealistic.

He discusses breathing and eye movement as ways he thinks about falling back asleep, and imagines sleep masks that could help with transitions into sleep. He frames the mask as a technology he is excited about, not an established everyday solution.

His larger point is to find practices that fit the circumstances rather than fear every imperfect night. He says he would like eight hours of uninterrupted sleep but often gets less, and tries to manage his energy accordingly.

For founders, Huberman's first cognitive-performance principle is to identify personal windows of high capacity. He wakes early but experiences sleep inertia; exercising before 9 a.m. tends to give him energy, whereas exercising at 11 can leave him tired later.

His key morning work window is roughly 9:30 to 12:30, followed by another in the late afternoon. He emphasizes that these times are individual and can change with circumstances. Health routines should support important work and life, not consume all available energy.

He treats those periods as protected work bouts, allowing interruptions mainly for emergencies. He doubts that most people can sustain eight or nine hours of total concentration every day without paying for it afterward.

As a contrast, he describes Rick Rubin doing his sharpest work in the afternoon. The schedules differ, but both involve knowing when the best work happens. Huberman believes losing a peak window to a distraction can also push work into time intended for personal life.

A second practice is stepping out of constant stimulus and response, even briefly, to check where attention and energy are going. Huberman says conversations and online material can linger in his own mind and affect the next task.

He argues that switching tasks may benefit from a pause without new inputs, although he says more research is needed. He and Rubin are exploring tools to help people prepare mentally for what comes next, distinct from meditation or yoga nidra.

The pair discuss possible neurotechnology, including personalized coaching and devices intended to support focus or transitions into sleep. Huberman is enthusiastic about the possibilities, while noting that the brain activity associated with different kinds of work is not yet clear.

He describes trying a sleep mask that uses stimulation and says it put him to sleep quickly. He speculates that sleep and waking may be earlier applications for such tools because the desired state is clearer than it is for creativity or focus.

Focus, he says, requires an intermediate level of alertness: being either too sleepy or too aroused can make a person distractible. He imagines future systems adjusting their approach to the individual, but presents this as a direction for development.

Huberman returns to the analogy of an athlete. When he was doing laboratory research, he found that sleeping earlier before a conference or consistently finding an extra hour for experiments affected his ability to perform over time.

He values a day each week away from work to make re-engagement possible. His father, also a scientist, told him to think like a long-distance runner: the work is an endurance event.

He recalls neurologist Bob Knight advising him to find the maximum amount of real work he could sustain each day, then find a non-destructive way to reset weekly. For Huberman, that reset is hiking in nature and spending time with people.

He says he kept a demanding but consistent rhythm for many years. People vary in their capacity, and pushing with stimulants until they crash is not the same as building endurance. His closing advice is to work hard and focus while also working out how long the pace can be maintained.
