Andrew Huberman’s Morning Routine, Tested Against an Office Job

The alarm goes at 6:40, the phone is in your hand by 6:41, and by 7:15 you have read forty emails under a ceiling light without seeing the sky. The Andrew Huberman morning routine starts at the opposite end: get outside within an hour of waking, look toward the daylight for ten to thirty minutes depending on the cloud, wake at the same time every day, and hold your first caffeine back by 90 to 120 minutes.

That is most of it. Everything else attached to his name online, the cold plunges, the supplement stacks, the precise breathing counts, comes from other episodes or from the people who summarise him.

We read his own published guidance, set it against an ordinary office week, and sorted what holds up from what is just a preference. One of the four habits has thin evidence behind it. The other three cost almost nothing and are worth keeping.

What the Andrew Huberman Morning Routine Actually Says

Huberman hosts the Huberman Lab podcast, and his own written summary of the morning, in the Huberman Lab Toolkit for Sleep, is short. View sunlight by going outside within 30 to 60 minutes of waking. On a bright cloudless day, ten minutes. On a cloudy day, twenty. On a very overcast day, thirty to sixty.

He adds two conditions. Do it outdoors, rather than from behind a desk. Leave the sunglasses off if you safely can, though ordinary glasses and contact lenses are fine. He also recommends repeating it in the late afternoon, before sunset.

The second habit on the same page is a fixed wake time: wake at the same time each day and go to bed when you first start to feel sleepy. The third, from a December 2022 episode on caffeine, is the delay: he recommends people “delay your caffeine intake to 90 to 120 minutes after waking up on most days”.

Read together, the three habits are about timing rather than effort. None of them asks you to do more in the morning. They ask you to do a few ordinary things at a particular hour.

That framing matters for anyone with a full diary. A routine that adds an hour of rituals before work fails by the second Wednesday. A routine that moves things you already do, a walk, a drink, a wake time, has a chance of surviving a quarter.

The Light Rule, Measured Against a Commute

The light habit is the one that matters most and fits an office job best, because most office workers already go outside in the first hour. They just do it in a car, on a platform staring at a phone, or through tinted glass.

The fix is small. Get off the train one stop early. Park at the far end of the lot. Take the first call of the day standing outside the building rather than at the desk. Ten minutes in open daylight on a clear day is the whole requirement, and a commute usually contains it if you stop looking down.

Winter is harder. In December a 6:40 alarm can go off well before sunrise, so the first hour may be dark. Huberman’s toolkit allows for this in its sidebar version, which suggests ten to fifteen minutes of sunlight right after waking, especially if you wake before sunrise. In practice that means getting out as soon as there is daylight, even if it is at 8:30 between the car and the lobby.

Cloud changes the dose rather than cancelling it. His numbers stretch to thirty or sixty minutes on overcast days rather than telling you to skip it.

What we would not do is buy anything for this. Light boxes exist for people with real seasonal problems and a doctor’s advice. For an executive whose only problem is sitting indoors from 6:40 to 19:00, the outdoors is free and works better.

The Caffeine Delay, and What the Evidence Says

This is the habit that made the Andrew Huberman morning routine famous, and it is the one with the least behind it.

His reasoning, set out in the caffeine episode, runs like this. Adenosine builds up in the brain while you are awake and creates the pressure to sleep. Caffeine blocks the receptors adenosine acts on, but it does not clear the adenosine away. Drink coffee straight after waking and, by his account, the leftover adenosine is still there when the caffeine wears off, which is how he explains the early afternoon crash. Waiting gives the body’s natural morning rise in cortisol time to do some of that clearing first.

It is a tidy mechanism. The problem is that nobody has tested the timing. Michael Grandner, who directs the sleep and health research programme at the University of Arizona, put it plainly in a 2025 interview republished by the university’s psychiatry department: “there are no studies on what the optimal timing should be”. Grandner’s own habit is to wait 30 to 60 minutes, and he described timing as more about personal preference.

So treat the delay as an experiment, not a rule. Try it for two weeks with the same wake time and the same total caffeine, and judge it on one thing: whether the slump after lunch gets smaller. If it does, keep it. If you just spend the first two hours of the workday foggy and irritable, drop it. A 9:00 board call is a bad place to discover you needed the coffee at 7:30.

The more useful part of his caffeine advice sits at the other end of the day. His toolkit says to avoid caffeine within eight to ten hours of bedtime. For someone who sleeps at 23:00, that means the last cup at around 13:00 to 15:00, which is a bigger change for most executives than anything they do in the morning.

Wake Time Over Wake Hour

The fixed wake time is the least glamorous habit and probably the most useful. The toolkit puts it in one line: wake at the same time each day and go to sleep when you first start to feel sleepy.

The point is consistency rather than earliness. A 5:00 alarm on weekdays and 9:30 on Saturdays gives your body jet lag every Monday. A 6:30 alarm every day, weekends included, gives it a fixed anchor, and the light habit then lands at the same point in the cycle each morning.

This is where his routine overlaps with Jeff Bezos’s morning routine, which we covered yesterday. Bezos talks about eight hours of sleep and a slow start because tired decisions are worse. Huberman arrives at a similar place from the biology side. Neither of them is selling a 4:00 alarm.

The fixed hour also helps the rest of the day hold its shape. A productivity plan built around a protected first block of work only works if the first block starts at a predictable time, and that depends on the alarm going off at the same minute every day.

Why Executives Get the Morning Wrong

The common failure is that the first hour belongs to other people. Email, overnight messages from another time zone, the news. By the time the executive leaves the house, a dozen other people have set the agenda, and the light habit has been spent inside reading.

Moving the phone to the second hour is the simplest structural change, and it makes the light habit almost automatic, because there is nothing to look at on the walk except where you are going. It also means the first hard thinking of the day happens on something you chose.

The stakes of that are not abstract. The calls that matter most, the ones we covered in our piece on Jeff Bezos’s regret minimization framework, deserve the hours when you are sharpest, and for most people that is the late morning after a decent night.

Pressure plays into this too. A morning that starts with forty emails starts with forty small demands, and our piece on stress tolerance covers how that kind of constant low-level load wears down capacity over weeks. Ten quiet minutes outside before the inbox is cheap recovery.

What an Executive Should Keep, and What to Drop

Keep the light. It is free, it fits inside a commute, and it is the habit with the clearest reason behind it. Ten minutes outside on a clear day, longer when it is grey.

Keep the fixed wake time, weekends included. It is boring and it works, and the light habit depends on it.

Test the caffeine delay for two weeks and keep it only if your afternoons improve. There is no study telling you the right number of minutes, so your own afternoon is the best evidence you will get.

Move the late caffeine cut-off up the list. For most people with a 23:00 bedtime, it is the change with the biggest effect on sleep.

Drop anything that needs buying. The internet has attached a long list of products to this routine. His own written morning guidance needs a pair of shoes and a door.

And drop the guilt when it slips. A red-eye, a sick child or a 7:00 call from Singapore will break it. The fixed wake time is what brings you back the next day.

Fitting It Into a Real Week

Start with one habit, not four. If you only change one thing, make it the light, because it attaches to something you already do. Once the walk is automatic, add the fixed wake time on weekends, which is usually the part that slips.

Write down what you are testing and when you started. It sounds trivial, but two weeks later nobody remembers whether the afternoons were worse before or after. Our piece on how to remember things quickly makes the point for meetings, and it applies here: if you do not write it down within the hour, the detail is gone.

Budget for it the way you budget for anything else that matters. Executives happily read a guide to net worth by age to see where they stand on money. Sleep and morning light are the same kind of asset, built slowly and spent quickly, and nobody sends you a statement.

If you are weighing a bigger commitment, such as the evenings and weekends an executive MBA takes, the morning routine is a useful early test. A person who cannot protect ten minutes of daylight will struggle to protect half their weekends.

The same goes when you are reading the fine print of a new compensation package. Hours and travel expectations shape mornings more than any routine, so ask about them before you sign.

Owners have it slightly easier, because the calendar is theirs. An owner preparing to sell a small business over the next two years will spend many early mornings on the books, and arriving at them rested is part of getting the numbers right.

Reading is a good use of the delayed-caffeine window if you try it. Some of the Warren Buffett books we looked at this week reward a slow, clear-headed hour more than a rushed one.

Frequently Asked Questions

What is Andrew Huberman’s morning routine?

In his own published guidance it comes down to four things. Go outside for daylight within 30 to 60 minutes of waking, for about ten minutes on a clear day and longer when it is cloudy. Wake at the same time every day. Delay caffeine by 90 to 120 minutes after waking. Avoid caffeine within eight to ten hours of bedtime.

Does looking at sunlight through a window count?

Not by his written guidance, which tells you to go outside. Ordinary glasses and contact lenses are fine, and he suggests leaving sunglasses off if you safely can.

Is the 90 minute caffeine delay backed by research?

Not for the timing itself. Sleep researcher Michael Grandner of the University of Arizona has said there are no studies on the optimal timing of the first coffee. Treat it as a two-week personal test and judge it on whether your afternoon slump shrinks.

The habits that hold up are the cheap ones: daylight in the first hour, the same alarm every day, and an early afternoon cut-off for caffeine. Most executives can have all three by Friday without changing anything except where they look on the way to work.
