Huberman's Protocols Book: Key Habits And How To Track Them

Protocols came out on 15 September 2026 from Simon & Schuster. Huberman is a neuroscientist at Stanford School of Medicine and the host of the Huberman Lab podcast. The publisher describes the book as a guide to "improving brain function, enhancing mood and energy, optimizing bodily health and physical performance, and rewiring your nervous system".

Each protocol has a plain instruction for a title, such as Resistance Train Three Times per Week or Avoid Screens Within an Hour or More Before Bedtime. That format is what makes the book easy to turn into habits: most titles already say what to do and how often. The sleep chapter alone runs to more than a dozen protocols, though, and Slate's reviewer, who read all of it, ended up with a checklist of 15 new things to remember every day. Picking a few and repeating them beats attempting the lot.

The light chapter opens with View Bright Light in the First Hour After Waking, and the publisher's description of the book gives "viewing sunlight as soon as possible after waking" as its example of a simple sleep protocol. The book adds evening light too: View Sunlight in the Late Afternoon and/or Early Evening.

The idea behind it is that light sets the body clock. In a study by Kenneth Wright and colleagues, people's clocks were measured at home and again after camping with only natural light. Living indoors under electric light meant less sunlight in the day, more light after sunset and a later body clock. After natural light only, the clock lined up with the sun, and people with later chronotypes shifted the most. The study measured a camping trip, not a ten-minute walk, so it supports the direction of the advice rather than a dose.

In HabitKit: a Yes / No habit called "Morning light", ticked when you have been outside within an hour of waking. Pair it with something that already happens, like the first coffee or walking the dog, and keep the cue in the name: "Coffee outside".

Adjust Your Caffeine Schedule to Improve Your Sleep is one of the book's sleep protocols. The best-known version of Huberman's advice is to wait a while after waking before the first coffee. The research below is about the other half, a cut-off well before bed, which is where the firmer evidence sits.

Christopher Drake and colleagues gave people 400 mg of caffeine, roughly the amount in a few strong coffees, at bedtime, three hours before or six hours before, and compared each with a placebo. All three doses significantly disturbed sleep compared with the placebo. The authors concluded that caffeine taken six hours before bed "has important disruptive effects on sleep" and that people should avoid substantial caffeine for at least six hours before bedtime.

In HabitKit: this one works best as a quit habit (choose Quit A Habit under Habit type) called "Coffee after 2 pm", or whatever time sits at least six hours before your bedtime. A quit habit counts clean days on its own, so you only log the days you slipped. Track a bad habit you want to quit explains how quit streaks count.

Avoid Screens Within an Hour or More Before Bedtime is the sleep chapter's evening rule. It rests on the same light-and-clock logic as the morning protocol, run in reverse.

Anne-Marie Chang and colleagues compared reading on a light-emitting e-reader with reading a printed book in the hours before bed. With the e-reader, people took longer to fall asleep, felt less sleepy in the evening, produced less melatonin, had a later body clock and were less alert the next morning. The study tested hours of reading on a tablet in a lab, so a short scroll on a phone is an extrapolation, but it points the same way.

In HabitKit: a Yes / No habit called "Phone out of the bedroom", with a Reminder set an hour before you want to be asleep, so the nudge arrives when it can still change something. Set a reminder for a habit shows where reminders live.

The exercise chapter starts with the least demanding protocol in the book: Walk as Much as Possible Each Day.

The evidence for walking is unusually broad. Amanda Paluch and colleagues pooled data from 15 cohorts with 47,471 adults whose daily steps had been measured. More steps per day went with a progressively lower risk of death from any cause, levelling off at around 6,000 to 8,000 steps for adults aged 60 and over and 8,000 to 10,000 for younger adults. These are associations from observational studies, not proof that the steps alone caused the difference, but they also suggest that the famous 10,000 is not a cliff edge.

In HabitKit: a Count habit called "Steps" with a Daily Goal and On Tap set to Enter total, so you type the day's number instead of tapping thousands of times. Or a Measure habit in kilometres or minutes if you do not wear a step counter. The tile fills in five partial shades as you log, so a 5,000-step day still shows as progress. Set daily goals and track counts or measured amounts covers both.

Two of the book's exercise protocols are Resistance Train Three Times per Week and Do Cardiovascular Training Three Times per Week. That is a little above the public health baseline. The World Health Organization's 2020 guidelines recommend 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous activity a week for adults, plus muscle-strengthening activities "on 2 or more days a week".

Three times a week is also a good shape for a habit, because it leaves four days of slack. You do not need to train on Monday, Wednesday and Friday. You need three days out of seven, whichever three the week allows.

In HabitKit: add "Strength training" and "Cardio" as two Yes / No habits and give each a weekly goal:

1. Open the habit and tap Edit.
2. Under Repeat, tap the card to open Goal & Streak.
3. Choose Times a week. It starts at 3 / week; use the plus and minus buttons to change it.
4. Under Count my streak in, choose Weeks.
5. Go back to the edit screen and tap Save.

Illustrative demo data. The three days move around from week to week; the goal only asks for three.

The streak now counts weeks that reach three, not days in a row. In the app's words: "Days off inside a good week never count against you."

The stress chapter's quickest tool is one to three physiological sighs: two inhales, the second one topping up the first, then a long, slow exhale.

A daily version of that breath, repeated for five minutes, has been tested in a study Huberman co-authored. Melis Yilmaz Balban and colleagues randomly assigned 108 participants to five minutes a day of cyclic sighing, box breathing, cyclic hyperventilation or mindfulness meditation for a month. Breathwork, "especially the exhale-focused cyclic sighing", improved mood more and lowered breathing rate more than meditation did. In the authors' words: "Daily 5-min cyclic sighing has promise as an effective stress management exercise."

One detail from that study is worth knowing before you start. Even with a daily practice of only five minutes, the breathwork groups did it on about 20 of the 28 days on average. Expect to miss days, and plan for that rather than against it.

In HabitKit: a Yes / No habit called "5 minutes of sighing", or a Measure habit in minutes if you want to see the time add up. Tie it to a fixed point in the day, such as straight after lunch or before you open your laptop. How to choose a habit cue covers why the anchor matters.

One of the nutrition chapter's protocols is that 90 percent or more of what you eat should be unprocessed or minimally processed food.

The best evidence behind the general idea is a tightly controlled trial. Kevin Hall and colleagues at the NIH had 20 adults live in a clinic for four weeks, eating an ultra-processed diet for two weeks and an unprocessed one for the other two. Both diets offered the same calories, sugar, fat, fibre and salt, and people ate as much as they liked. On the ultra-processed diet they ate about 500 calories a day more and gained weight. On the unprocessed diet they lost about the same amount. It was a small, short study, and it did not test a 90 percent rule, but it is a clean result.

In HabitKit: "90 percent" is hard to log, so track the part that usually breaks it. A quit habit called "Packaged snacks", using Count with a Stay Below of 1, keeps a day clean as long as you log none, and the count shows how many slipped in on the days that were not. Or build the positive side with a Yes / No habit like "Cooked dinner from scratch" and a weekly goal.

Two protocols from the later chapters are mental habits rather than physical ones. One is Use Mental Contrasting to Achieve a State of Urgency. Mental contrasting means picturing the outcome you want, then the obstacle most likely to stop you. The other is Resolve Inner Pain Points Through Expressive Writing: writing openly about something difficult, usually over a few short sessions.

Both have meta-analyses behind them, with modest effects. Guoxia Wang and colleagues pooled 21 studies with 15,907 participants on mental contrasting combined with if-then plans, and found a small-to-moderate effect on reaching goals (g = 0.336), noting that publication bias may make the true effect smaller. Joanne Frattaroli pooled 146 randomised studies of expressive writing and found a positive but small average effect.

In HabitKit: a Yes / No habit called "Weekly plan", set to Times a week at 1 / week with Weeks under Count my streak in, and a Sunday evening Reminder. To write the plan down, press and hold the day in the habit's calendar to open the day editor, and use its note for the one obstacle you expect and what you will do if it shows up. Log a completion and fix a past day shows where notes live.

An illustrative note. Goal, obstacle and an if-then plan fit in three lines.

The book is long and the protocols are many, and that is a trap for anyone who finishes it on a Sunday and wants to start everything on Monday. Pick the one or two that solve your biggest problem: light and screens if you sleep badly, walking and strength if you sit all day, the sigh if stress is the issue. Add the next one only when the first runs without thinking.

HabitKit's free version tracks four active habits, which happens to be a sensible ceiling for a first round anyway. Habits take time to settle: in the best-known study the median was 66 days, with a very wide range. How long it really takes to form a habit covers what that number does and does not mean, and how to start a small habit you can repeat has more on choosing the first version.

Keeping a record helps. A meta-analysis of 138 studies by Benjamin Harkin and colleagues found that monitoring progress helped people reach their goals on average, and more so when the progress was physically recorded. That is a result about tracking in general, not about any particular app.

It varies a lot from protocol to protocol, and the book does not always say so. Walking, strength training and cardio rest on large bodies of research and official guidelines. The caffeine cut-off, evening screens and morning light have small but well-controlled lab and field studies behind the mechanism, though not for every exact number in the book. The breathing study is a single randomised trial co-authored by Huberman. Mental contrasting and expressive writing show small average effects.

Reviewers have made the same point. Slate's review noted that even where the book admits the evidence is thin, as when it says "larger and longer-term studies are needed" for one sleep aid, it still nudges readers to try the thing, and that it states other claims more confidently than the research allows. The useful way to read Protocols is as a menu of reasonable experiments. Track one for a few weeks, notice whether you sleep, feel or perform better, and keep the ones that earn their place.

What Are The Huberman Protocols?

They are the step-by-step routines in Andrew Huberman's book Protocols: An Operating Manual for the Human Body, published in September 2026. The book groups them into seven areas: sleep, exercise, stress control, nutrition, light, focus, motivation and learning, and personal growth. Examples include viewing bright light in the first hour after waking, resistance training three times a week and doing one to three physiological sighs to calm down.

Which Huberman Habits Are Easiest To Start With?

The ones that are a single yes-or-no decision: getting outside within an hour of waking, a daily walk, and putting screens away an hour before bed. They need no equipment and fit a simple tick in a habit tracker. Start with one that fixes your biggest problem, and add the next once it runs on its own.

Is There Scientific Evidence Behind Huberman's Protocols?

For some, yes. Walking, strength training and cardio rest on large studies and official guidelines, and the caffeine cut-off, evening screens and morning light have well-controlled but small studies behind them. Others, including several of the exact timings, have thinner evidence. The section above on evidence goes through each one.

Can I Track Huberman's Protocols For Free?

Yes. HabitKit's free version tracks four active habits on iPhone and Android, with no account, which is enough for a first round of protocols. Each one in this guide works as a Yes / No, Count or quit habit.

How Long Does It Take For A Protocol To Become A Habit?

There is no fixed number. In the best-known study of everyday habits the median was 66 days, and individual estimates ranged far wider. How long it really takes to form a habit explains the study and its limits.
