Andrew Huberman

From tenured professor to top-10 podcast in one year, no PR firm

Huberman traces his arc: a 2019 question from a friend pushed him to start posting nerdy science on Instagram, COVID created demand for his stress/sleep tools, guest spots on Rogan/Rich Roll/Lex built an audience, and in Jan 2021 he bought mics and launched Huberman Lab with a punk/skate aesthetic and a classroom format. No PR firm, no contract.

“And he said, yeah, what are you really going to do? He was kind of poking at me. And I said, well, you know, I think, um, it'd be fun to just teach science on the internet and just put quality information out there because I don't see that. So I started doing that in 2019, little short posts, pretty nerdy stuff, mostly on Instagram. and people seem to like it.”

Turn comments into content: ask for episode ideas, run office hours

Huberman actively asks followers to leave suggestions in the comments and reads every one, then devotes entire 'office hours' episodes to the most frequently asked questions. This gives the audience an incentive to engage and turns the comment section into a non-combative content pipeline.

“comment sections are great, but better to make them interactive. So I actively request and we read every single comment. I say, tell me, like, give me, give us feedback, but also give us suggestions and give us ideas about future podcasts. And then I've devoted entire episodes. We haven't done one in a while, but to what we call office hours.”

Get sunlight in your eyes for 10-30 minutes every morning

Huberman's most-repeated foundational practice: after waking, drink water and go outside to get sunlight in your eyes for 10 to 30 minutes, even on cloudy days, without sunglasses. He says missing it for more than two days in a row degrades the rest of his life.

“I drink water. I hydrate and I go outside and I get some sunlight in my eyes for 10 to 30 minutes. Foundational, absolutely critical practice. When I don't do it for more than 2 days in a row, I start messing up all sorts of aspects of my life. And most people are not doing this. Even on cloudy days, do it. Don't wear sunglasses unless you have a medical reason why you need to.”

Steal thisFirst thing after waking, hydrate and stand outside for 10-30 minutes to get sunlight in your eyes, no sunglasses, even when it's cloudy.

Delay caffeine 90-120 minutes after waking to avoid the afternoon crash

Huberman waits 90 to 120 minutes after waking before any caffeine. The reasoning: caffeine blocks adenosine, so drinking it too early sets up a bigger afternoon crash when it wears off; waiting lets your natural adenosine taper down and prevents the rebound.

“I don't drink any caffeine until 90 minutes, or ideally 120 minutes, after I've woken up for the following reason. Uh, during sleep, uh, you— well, during wakefulness, you— and the longer you're awake, adenosine builds up in your system. Caffeine is an adenosine antagonist functionally. I realize it's a competitive agonist for you aficionados, but it basically blocks the adenosine receptor functionality, so to speak. But when that caffeine wears off, you're going to get a big crash because there's going to be a surplus of adenosine.”

Steal thisWait 90-120 minutes after waking before your first coffee to dodge the afternoon energy crash.

Foundational practices raise the tide so your boat can leave harbor

Huberman's 80/20 for feeling better: morning sunlight in your eyes ~365 days a year, and getting sleep right until you sleep well 80%+ of the time. He frames these not as a turbo boost but as foundational practices that 'raise the tide so your boat can leave harbor.'

“It's a foundational practice. So I like to think of it as it raises the tide so that your boat can leave harbor. That's how I think of it, rather than, oh, this is like putting another outboard motor on my vessel. Okay, so that's the first one. And the second one is a little bit of a broader category, but it's get sleep right. You have— if you're— until you're sleeping well 80% of the time or more, get your sleep right.”

Steal thisFix the foundational inputs (morning light, sleep) before reaching for stimulants or hacks; they raise the baseline everything else runs on.

Cal Newport's 'So Good They Can't Ignore You' and 'Deep Work'

Huberman calls Cal Newport a true pioneer of the mental-frame space and points to 'So Good They Can't Ignore You' (build rare skills rather than chasing passion) and 'Deep Work,' from which he says he's essentially paraphrasing his focus protocols.

“So, so Good They Can't Ignore You is an incredible book. Everyone should be required to read that book. Um, Deep Work is this— I'm essentially paraphrasing some of the protocols from Deep Work, but Cal, who I don't know, have never met, but have great respect for, um, it's a computer science professor, uh, back East.”

Win one 90-minute deep-work block; context switching is deadly

Huberman's mental-frame playbook, borrowed from Cal Newport: protect one 90-minute block in the morning where you push through resistance and refuse to switch contexts. Getting good at the brain's 'no-go operations' lets you drop into that focused state faster everywhere else in life.

“I want to have one 90-minute block that I completely conquer, that is where I experience immense resistance to do something other than what I'm doing, but that I stay in, noodling away, or gnawing away would be the better word, at writing something or reading something or trying to comprehend something. And you have to be very careful The moment you walk to the restroom and then maybe like wash your hands and look yourself in the mirror, and then you're like, oh, you know, I got this weird hair growing on my cheek or something, you're starting to switch mental frame.”

Steal thisBlock one 90-minute deep-work session each morning, kill all context switching, and you'll learn to enter that focused state faster anytime.

A pinch of salt in water kills hunger and shakiness

When people feel shaky and think they need sugar, Huberman says their electrolytes are low: a pinch of sea salt in water raises blood volume, kills hunger, and buys another couple of hours of good brain function (caveat for those with hypertension).

“I put salt in my water, which kills your hunger a lot of the time. A lot of people get shaky. They think they need sugar. Your electrolytes are low. Just put some sea salt or a little pinch of salt in water, drink it like, oh, I can go another 2 hours. And your brain function's great. Blood volume goes up.”

Steal thisWhen you feel shaky and reach for sugar, drink water with a pinch of sea salt instead to kill hunger and steady your brain.

Reread Tim Ferriss's 4-Hour Workweek and 4-Hour Body

Huberman credits Tim Ferriss's 'The 4-Hour Workweek' and especially 'The 4-Hour Body' with accelerating his science career by teaching him to focus on what really matters, and says everyone should be rereading them.

“That podcast, 4-Hour Workweek, 4-Hour Body especially, had a tremendous impact in accelerating my career in science because I was able to focus on things that really matter. Maybe not just 4 hours, but just the principles in those books. I think we should all be rereading those. Books. They're so damn good.”

The right supplements can raise testosterone by ~200 ng/dL

Huberman says properly sourced Fadogia and Tongkat Ali can raise testosterone by about 200 nanograms per deciliter, with the most dramatic case he's seen going from the high 200s to the 800s-900s, before he tried a small-dose TRT experiment for his book.

“But those supplements done properly from the right sources can increase testosterone by about 200 nanograms per deciliter. The most dramatic I've ever seen is a shift from about 300 to, or high 2s to like, you know, 8s and 9s.”

Short stress raises testosterone; long stress depletes it

Citing peer-reviewed work by Duncan French of the UFC Performance Institute, Huberman says short-term stress raises testosterone, while stress lasting more than a day or two, or training sessions over 90 minutes, depletes it.

“I just did a podcast episode with Duncan French from the UFC Performance Institute. Duncan's work has shown in peer-reviewed studies that short-term stress raises testosterone. Stress that lasts more than a day or two, or training sessions that go more than 90 minutes, that depletes testosterone.”

Roughly $2 million in ad revenue per podcast episode

Sam estimates Huberman's podcast earns $5-10 million a month; Huberman, who claims not to track the numbers himself, agrees it's on the higher end and floats roughly $2 million per episode in the first couple of weeks.

“Because if it's about $2 million per episode in the first couple of weeks, is that something— I don't know.”

A podcast network where each expert does 6-7 episodes, not forever

Huberman reveals Huberman Lab is one show under a company he founded with Rob Moore, with David Sinclair's Lifespan and two more revving up. The model: most experts have deep info on a niche (gut microbiome, ADHD, Parkinson's) that fits 6-7 episodes, not a podcast in perpetuity, so an umbrella network lets listeners come to whichever expert they need.

“And so they need to do 6 or 7 episodes, but they probably don't need to do an a podcast in perpetuity. And so the idea is to have a set of podcasts that you can come to mine if you like, David's if you like.”

Steal thisBuild an umbrella podcast network of subject experts who each do a tight 6-7 episode run instead of committing to a forever show.
