Become Mentally Dangerous With These Daily Habits

Raj's question: take a 25-year-old and make them "mentally dangerous" in 10 years, with an unshakable, elite-performer mindset that never collapses under pressure. Where do you begin? Huberman's answer, boiled down:

1. High morning cortisol, low nighttime cortisol. "If I only had 5 minutes to talk to somebody," this is the one thing he'd say.
2. Learn to turn your mind off. Anyone can hit the gas. The person who can switch off in the final hour and sleep deeply wins over 5-10 years.
3. Know thyself. Always know what state you're in before you act.
4. Take yourself seriously. That means both the gas pedal and the brakes, like a pro athlete.
5. Go all in for years 1-3, learn to regulate in years 4-6, and be a pro from year 7.
6. Build resilience with small daily reps: 10 breaths before getting up, cold showers with "walls", harder work sets, a wider gaze, and remembering what you survived.

Cortisol isn't really a "stress hormone." Its main job is to deploy energy (glucose and lipids). You want it spiking in the morning and low in the last hour before sleep.

Why it matters so much

• This pattern gives you more daytime energy, focus, learning and stress resilience, and makes it easier to fall into deep and REM sleep, which repairs the body, consolidates learning and removes yesterday's emotional load.
• It's also the pattern that optimizes immune function, for men and women of all ages. You get sick less.
• Cortisol and melatonin run on opposite cycles. A high morning peak means less leftover melatonin (more alertness), and low cortisol at night lets melatonin peak higher. Many sleep problems "just kind of disappear."
• Why start with the morning? The morning peak works through a negative feedback loop: once it spikes, it suppresses itself, which keeps afternoon and evening cortisol low. It's "a wavefront that starts the 24-hour cycle."
• With a strong morning peak, later stressors (an upsetting text, a deadline) cause only brief spikes, and cortisol returns to baseline faster.

"Morning" is relative to you

Morning means the first hour or two after you wake, not a clock time. Raj's natural schedule is 1-2 a.m. to 10 a.m.; Huberman's morning is 6:30. Neither is better. Naturally, cortisol is lowest 2-3 hours into sleep, climbs faster in the last third of the night, and the cortisol awakening response is literally what wakes you up.

Morning protocol (first 30-60 minutes)

• Get bright light in your eyes. Go outside for 5-10 minutes and look toward the sun, without sunglasses or a brimmed hat (glasses and contacts are fine). Never stare at it: squint or look slightly away. This can raise your cortisol peak by up to 50% within 5-10 minutes. It matters even more on cloudy days.
• No sun? Use a 10,000 lux light. He travels with a tablet-sized one and keeps them in his bathroom and kitchen.
• Hydrate and have your tea or coffee. Both boost cortisol further.
• Move: a walk, jumping jacks, or ideally a workout.
• Don't lie in bed looking at your phone. Going outside is a forcing function against that.
• Do it daily and your body starts raising cortisol in anticipation (it becomes "entrained").

Evening protocol (final hour)

• Dim the lights. Light hits melanopsin cells in the eye that signal your circadian clock to suppress melatonin. "Bright mornings and days, dim or dark nights."
• No caffeine in the final 8 hours before sleep (some people can tolerate a little later; many can't).
• Let your body temperature fall. A cooling core is what brings melatonin up.
• Don't drink much, so you don't wake up to pee. If you're thirsty, drink a little.
• If you're wound up, do long exhale breathing (next section).

• Respiratory sinus arrhythmia: a vigorous inhale moves the diaphragm down, the heart gets slightly bigger, blood flows more slowly, and your brain speeds up your heart rate. A long exhale does the opposite: the heart gets more compact and the vagus nerve slows your heart rate.
• That brake is what HRV (heart rate variability) measures: your parasympathetic system hitting the brakes. High HRV is good.
• Five extended exhales during the day, or three, or one long one before sleep, teach your nervous system to slow your heart. Your sleep HRV will be significantly higher.
• A deliberate long exhale lowers heart rate immediately and lowers cortisol within a few minutes.
• He credits India for thousands of years of breathwork.

Give me two people. Both can work very, very hard, both extremely committed, both with perfect circumstances. The person that can turn their mind off in the final hour of their day and get the better, deeper sleep, I'm going to put all my money on that person.Andrew Huberman

• Everyone knows how to ramp up (music, a pep talk, a YouTube video). Very few know how to ramp down. The best athletes do. It's a skill.
• Fully relax or fully work, never a hybrid. On a delayed flight he picks one: complete rest (scroll, watch a movie, call your mother) or real work. The in-between is what drains you.
• "When our mind is split between two places, that's the most taxing thing." The mind thrives on unitary states. Sadly it slips easily into unitary states like anger, and algorithms are designed to put you there.
• Scrolling Instagram is fine if it actually resets you. What's not fine is scrolling while thinking "I should be doing yoga nidra."
• He outlasted peers at scientific conferences by going to bed early while others drank. By day three they were drooling in meetings; he was in the front row. "I'm going to pass the next person by what I don't do as much as by what I do."
• You don't need to be David Goggins to be in a pressure test. Every stressor is a rep of stress resilience: "The more stress, the more opportunity."

Your mind is steerable

The brain works in dynamic attractor states. Picture a thought as a ball bearing on a flat surface. The more you think about something, the more the surface caves into a trench and the ball gets stuck. Usually something big knocks it out (a friend, sleep, exercise). But you can learn to steer: "At 50 years old, I finally realized it's possible to control one's thoughts." You can't eliminate thoughts, but you can decide where your mind goes.

From Andy Stumpf, a former tier-one Navy SEAL (podcast Clearing Hot, book Drown). About once a month:

1. On a sheet of paper, write everything that concerns you in the left column: what people think, worries, outcomes.
2. In the right column, write what you can actually control: exercise, hydrate, sleep, practice turning your brain off, call your mother.
3. You'll see you have almost no control over the left column.
4. For the next month you'll notice which column each thought is in. "That's a left-column issue" is now a saying in his studio.

How to get back to the right column: get extremely present with literal actions and sensations. "I can take a sip of water. I can smell the air in here. It's so quiet." Talking about left-column worries tends to build them rather than release them.

Alongside the cortisol rhythm, he calls yoga nidra the most powerful tool you can cultivate. He rebranded it as NSDR (non-sleep deep rest) so people in the West wouldn't dismiss it as "yoga", and he always credits yoga nidra as the origin.

• What it is: lie or sit down, breathe with long exhales, and move your mind from thinking, doing and planning into pure sensation (what you hear and feel). This is the first step in turning your mind off.
• Dose: 10, 20 or 30 minutes, 1, 3 or 7 days a week. Over a couple of years you get very good at it. Free scripts are on YouTube and his website.
• After a short night: do it first thing in the morning, or between 2 and 3 p.m. in the afternoon dip, then hydrate and have a little caffeine. Parts of the brain may enter deep or even REM sleep during it. "There is no pill that will do this."
• Any drug that takes you out of thinking and into pure sensation will rebound you into a rough place. Yoga nidra doesn't.
• Raj's story: during a phase of 3-4 hours of sleep and three podcasts a day, he did Huberman's NSDR audio in 30-minute gaps between guests (his team found him asleep under the table). 10-15 minutes gave him more energy than coffee.

The eye-movement trick (for falling back asleep)

To fall asleep you need to forget where your body is (proprioception). Your eyes are linked to the cerebellum, which controls balance, so moving them disrupts those circuits. It's the same reason rocking beds and a parent's slow sway put people to sleep.

1. Eyes closed, slowly look to one side, then the other.
2. Roll your eyes counterclockwise, then clockwise.
3. Look toward the tip of your nose (don't cross your eyes).
4. Exhale.

It won't override four cups of coffee or heavy rumination, but for waking at 2-4 a.m. it works for him and many people who've written to him. These circuits are plastic: you get better with practice.

• Know thyself sits deeper than every other tool. Before you act, check the engine: am I in a good state or a vulnerable one? If I open social media now, will I go down a rabbit hole? Under-slept or stressed means "my steering is not aligned", so compensate.
• Take yourself seriously. That doesn't mean rigid, joyless and no laughter. It means both hitting the gas and coming off it so you can do it again. A Formula 1 car needs pit stops, care and rest, and when and how you rest is key.
• If you don't take yourself seriously, you default to the mean of the culture around you: work hard, play hard, and soon you're playing as hard as you work. Or you sink with people who've given up.
• The gifted people who partied through conferences are "not in the field anymore." Genetics and circumstances carry you far, but everyone, gifted or not, needs to take themselves seriously to excel long-term.
• There's no such thing as eliminating all toxic people (toxicity comes through the phone). Aim to be the calm in someone's storm, so they can be the calm in yours.

• Resistance-training parallel: after 10-15 years of lifting you need fewer sets, because you can put far more intensity into each one. Beginners can't generate that intensity yet.
• Find your edge. Early on, test your limits: can you go two nights without sleep (he breaks), or one (he can)? Last week he did a 30-hour work stretch with his business partner. It hurt and he doesn't want to repeat it soon.
• Aim for a non-lethal wall ("I'm exhausted, I need a week off"), then work around that average, give or take 2 hours.
• His numbers: 5 to 10 hours of real work a day (not counting lunch or walks). 5 is easy, 6-7 hurts a bit, 10 means the next day he can only do 5, so it's borrowed.

Huberman says they arrived at this framework during the conversation, and he strongly believes it.

• Burnout signs in years 4-6: hair falling out, skin issues, autoimmune conditions. High-wired, driven people tend toward autoimmune problems. Others crash into chronic fatigue.
• The unit of time is the day. "What can I do today to get the most done, knowing I'm coming back tomorrow and want to do it again?" That mindset is also part of shutting your brain off.
• Don't quit before about three years of near-extreme effort. If you want to quit, ask kindly: do you really want this, or are you in the wrong domain?
• Handling dips (algorithm changes, slow periods) while other areas go well "comes with maturity." Quitting was never an option for him.

He has trained this way for 35 years. "Anyone can do this": any sex, age or hormone status. You won't be the fastest or strongest, but you'll get all-round fitness, good posture, and better blood flow to the brain and better sleep.

For the hypothetical 25-year-old: cardio or resistance training six days a week, one day of complete rest, even if they don't like working out first thing in the morning.

• Ashwagandha reduces cortisol potently (about 30% in one study at around 600 mg twice a day). Take it in the second half of the day, never to blunt the morning peak. High doses: 2 weeks on, 2 weeks off. Moderate doses (300-600 mg) are probably fine to take consistently.
• Sleep helpers: magnesium, theanine, apigenin (chamomile tea), ashwagandha.
• Pinealon (a peptide for REM sleep): only every once in a while. Relying on drugs to sleep short-circuits your ability to turn your mind off yourself.
• Stimulants early in the day: caffeine is his main one, plus alpha-GPC and energy drinks.
• Nicotine creates a coveted alert-but-calm state, but it raises blood pressure and is very habit-forming: one 3 mg pouch soon becomes five a day. He "loves competing with those guys" because of what it does to them over years.
• His dad's advice: "Learn to be a long-distance runner. You want to win the long game." Anyone can push hard in the short term; people just start dropping out.

• Lower the stakes and shorten the horizon. Don't commit to three years; commit to three days. Survive those, do three more.
• Chop wood, carry water. Finishing his 650-page book Protocols alongside the podcast, he did today's work simply because he said he would, and pushed resentment aside.
• Jumpers need timing, not recklessness. Excess (overspending, drugs, leverage, ego like "I built 10 companies, I can build 10 more") takes many successful people down.

Can you build courage? "Absolutely. Incrementally."

Take people to the edge of agitation and let them live there. Cold showers reliably trigger adrenaline, which briefly lowers prefrontal activity (it's hard to strategize and you want to escape). The training is to ride out those first 20-30 seconds.

The same principle works anywhere: turning the gym heat up for two more sets, working out in silence for full focus, or letting someone finish in a hard conversation before you speak. It's all "fighting our impulsivity."

• Flow is the expression of skills you already have. It comes in years 7+, once you have mastery, and "has nothing to do with learning."
• Clutch states (a term from Dr Tommy Wood, University of Washington): forcing yourself to perform at the edge of friction and effort. High performers live there 90% of their waking hours.
• Neuroplasticity comes from errors. If your nervous system can already do something, nothing rewires. The gap between desired and current performance releases adrenaline and norepinephrine, which let circuits rewire, and sleep then consolidates it.
• The progression is unskilled, skilled, mastery, virtuosity. Everyone wants virtuosity, but it's built on "clutch state, clutch state, clutch state."
• Self-test to learn: after a book or podcast, take a walk and ask "what did I learn?" Whatever you can't remember, look up, and you'll never forget it. He uses ChatGPT to generate self-tests.

1. 10-breath meditation before getting out of bed. "If I can't concentrate for 10 breaths, how am I going to go about my day?" Set an alarm, because long exhales can put you back to sleep. It's hardest when you really need the bathroom.
2. Make work sets as hard as possible. In working sets (not warm-ups), when it gets tough, contract even harder.
3. Dilate your gaze when overwhelmed. Stress creates tunnel vision, like drinking from a fire hose. Widen your view to take in the whole room, ceiling and floor. Your autonomic nervous system settles and you can pick things off one by one. Basketball players use it to spot openings; Jocko Willink arrived at the same tool.
4. Use memory for wins. Keep something that worked out: you survived that, or you built that. Acknowledge your own agency: "Had you not decided and done the things, it would not exist."
5. Do the slightly harder thing (Andy Stumpf): pick up that piece of trash. He admits he still hates folding clothes. "Pick your masochism, but be thoughtful about it."

The underlying mental trick: see your life as an adventure. You get to write your own story.

• Both have hard thoughts, emotions and despair. The difference is what you do, sometimes every 5 minutes.
• Never self-attack or attack others. Harm can look like words, skipping work or school, weed and video games, porn, or giving up.
• If you can't do anything generative, do nothing. Feel the feelings without getting out of the chair. "I made it 5 minutes. I'm in the driver's seat."
• It's hardest between 1 and 5 a.m., when you're under-slept, after alcohol, during a breakup or loss, or under several stressors. That's when the off-switch tools matter.
• Inspiration is just a rung on a ladder. You pulled yourself up, and knowing that lets you set your own rungs when none are there.
• Start basic: 10 breaths, 3 minutes in a cold shower, then yoga nidra (the hardest of the three).

At rock bottom

• Seek help. And, whatever you believe in (for him, God), say it out loud or in your head: "I'm at my end. Just help me get through the next hour." Stop trying to control everything. "I've never seen this fail."
• Once you're on solid ground, get to work, because "the universe only rewards effort."
• Get out of the pit a few times and next time you'll know you will get out again. Oddly, the pit's depth often mirrors the height of what you later achieve, so savor the peak.
• Some people live with a punishing inner voice. Goggins turns it into fuel; the rest of us have to turn it down, or crank it up and fight it. Either way you learn the algorithm.

• Attention is a drug if misused. Young stars often crash after peaks of attention and money, then chase them with substances or spending. Recycle attention into creative work and giving back instead.
• Raj cites research that power changes the brain somewhat like trauma: more impulsive, less grounded, worse decisions.
• Have a committee. Don't make every decision inside your own skull. Pressure-test with people you respect, but you decide. Sometimes you ignore everyone and do it anyway.
• Make the work itself a big part of the reward. For him it's learning and teaching; money and recognition are icing.
• Criticism: knowing you're fundamentally good gets you 90% of the way. Think of how broken someone must be to spend time posting cruelty, and send them love. Raj credits his joint family (10 people in one house, 30 on weekends): constant comparison made him immune to outside criticism. Huberman got the same from sports teams and science's endless "not good enough."
• Jocko's friendship test: good friends give you the hardest time to your face and never talk badly about you behind your back.
• Stay well online: the internet is "open waters," from very healthy to very unwell. Don't let it erode you.

• Some people are built with more drive: an internal "vibration" and friction with their circumstances, likely linked to the dopamine system. Steady "sustainers" are also essential to society. A test: when you see someone striving, do you feel fed or overwhelmed?
• If you're attached to any one thing as the answer (money, fame, more cars or marriages), you're headed for dismay.
• Why immigrants outperform: they see opportunity where locals see neutral or negative, because locals habituate to what's around them. His example: a taxi driver with a 7th-grade education who bought South Bay properties no one wanted and did all the maintenance himself, then Silicon Valley happened.
• Self-imposed friction matters if you grew up without hardship. The unhappiest people he knows got just enough family money never to push themselves. Hardship teaches the brain an algorithm: "I got out of friction."
• Technology trades skills for convenience (memory to phones, navigation to maps, maybe thinking to AI). Use it like DoorDash: fine, but still cook sometimes.
• Phone: put it in a drawer or lock box for a few hours of focused work daily. If you can't, "you have what's called a problem." He keeps Instagram and X on a separate old phone and uses a $15 timed lock box during workouts.
• Recognize you're being controlled and you can fight back. "It's never been easier to move ahead": just read a book, finish a podcast and have a healthy phone relationship.
• Ask yourself: "Am I a consumer or a creator right now?" Create a little every day. Raj's rule: become the producer of the thing you consume the most.
• The best work is non-competitive (a point from Rick Rubin). Build your own vision: "They don't want another one of you or another one of me."

• Relationships: he never struggled with the love part, only with choices. His fix: slow down, build the friendship first, and build deep trust, because you're handing someone a lot of power. He notes arranged marriages have high long-term success rates.
• Most powerless, three times: (1) his parents' divorce while his skateboarding dreams fell apart, which led to a spiral he dug himself out of; (2) losing all three scientific advisers (a suicide and two cancers), which left him an "academic orphan" until he turned that freedom into starting the podcast in his 40s; (3) a messy breakup where being misunderstood was the hardest part, until he realized he was "sitting in the promised land" and flicked it off "like a piece of lint."
• Grief isn't neat stages. It's the nervous system expecting to reach someone and not being able to, like food vanishing on the way to your mouth. His book has a protocol for it.
• Writing his will made him realize he's at peace: whether he dies at 50 or 110, "I'm good."
• The cost of being Andrew Huberman: he feels emotions very intensely and is very ambitious. He wants to help everyone and drop into every feeling, but has work to do. "Sometimes I feel like I'm trying to run fast with my shoelaces tied." Gratitude, God and prayer keep him in action and peace.
