Free comes first
Light, sleep, breath and movement cost nothing and do the most. Supplements and prescriptions come later, on top of the basics, never in place of them.

An Operating Manual for the Human Body
The body runs on a 24-hour clock, and most of its levers are free. What makes them work is when you pull them.

The core idea
A manual, not a manifesto.
Andrew Huberman, the Stanford neuroscientist behind Huberman Lab, turns years of podcast conversations into a manual of protocols: specific things to do, and when to do them, for sleep, exercise, stress, nutrition, light, focus and learning, and personal growth. The order matters as much as the list. Behaviour comes first, and supplements and prescriptions only after the basics, with almost everything keyed to the body's 24-hour clock.
A protocol here is something you can actually do: a specific action, at a specific time, for a specific length, with the reason it works written next to it. The point is to understand the mechanism well enough to adapt the protocol to your own life, not to follow it blindly.
One pattern keeps returning across the chapters. Timing matters as much as the action itself: when you see light, when you drink caffeine, when you train, eat and wind down. So the tool below starts from the one thing you control every morning, the time you get up.
- 01LightBright days, dark nights.
- 02SleepThe base the rest stands on.
- 03ExerciseWalk, lift, run, stretch.
- 04NutritionReal food, protein first.
- 05Focus, motivation & learningAlert and calm, in bouts.
- 06Stress controlBreath and deliberate rest.
- 07Personal growthWriting, gratitude, presence.
Pillar 2
Timing is a lever
The same coffee, workout or bright screen does different things at 8am and at 11pm. A protocol includes when to do it as well as what to do.
Pillar 3
State is trainable
Calm and alertness are both things you can shift on purpose, with your breath, light and rest. Learning goes best in the band where you are alert but calm.
Interactive · the protocol clock
Your day, one ring per chapter.
Set when you wake and when you sleep. Every protocol lands on the 24-hour dial in its own ring, timed from your morning, and the hand shows where you are now.
Chapters on the dial
HourLife's plan, built from the book's main protocols. It is general information, not medical advice. If you have a sleep disorder, are pregnant, or take medication that affects sleep, alertness or appetite, talk to a clinician before changing your routine.

Start at the top. Move down a tier only once the one above it is in place.

The state you are in
Most protocols move you along one line, from asleep to panicked. Learning goes best in the band where you are alert but still calm.

- Alert and calm (the learning zone)
- Stressed
- Panicked
Turn it down
A long exhale, the physiological sigh, a deliberate rest in the afternoon, dim light in the evening.
Turn it up
Morning daylight, movement, a set time for caffeine, and one hard task with a clear finish line.

Community insights
What readers keep.
Nº 01HourLife takeaway
Get bright light into your eyes early in the day, and keep the night dark.
Light is the main signal that sets the body's 24-hour clock. Morning daylight anchors it, and bright light late at night pushes it the wrong way. It costs nothing, and much of the rest of the book depends on it.
Nº 02HourLife takeaway
Behaviour comes first. Supplements and prescriptions come after the basics are in place.
The book puts the free levers first: sleep, light, movement, food and breath. Supplements and drugs come later, as additions to a working base and never as a substitute for it. If your sleep is broken, no capsule will fix it.
Nº 03HourLife takeaway
Sleep is the foundation the other protocols stand on.
Focus, mood, training and appetite all get harder on a bad night. The most useful anchor is a wake time that stays put, weekends included, because the rest of the day is timed from it.
Nº 04HourLife takeaway
You can change your state with your breath, and the long exhale is the part that calms.
The physiological sigh is a double inhale through the nose followed by a long, slow exhale through the mouth. It is a tool for the moment stress spikes, and it works without anyone noticing.
Nº 05HourLife takeaway
The best state for learning is alert and calm, not stressed and not drowsy.
A little arousal helps the brain change. Panic shuts learning down, and so does drowsiness. Many of the focus protocols are about getting into that middle band and staying there for one block of work.
Nº 06HourLife takeaway
Movement is a protocol for the brain as much as for the body.
A week that mixes walking, resistance training, cardio and mobility covers most of what the body needs. Walking alone shows up again and again as good for mood and memory.
Nº 07HourLife takeaway
Eat mostly unprocessed food, and start each meal with protein.
This is a rule of thumb rather than a diet. Food that looks like where it came from, with protein at the front of the plate, makes the other choices easier without counting anything.
Nº 08HourLife takeaway
Short rests during practice help a skill settle in.
Pausing for a few seconds between repetitions gives the brain room to replay what it just did. A practice session with small gaps in it can beat one that never stops.
Nº 09HourLife takeaway
Writing about what is hard, and noticing what you are grateful for, are protocols too.
The last chapter turns to the inner life: expressive writing, gratitude, presence and grief. Like the other protocols, they are short, specific and repeatable.
Action steps
Set it up once, then run it daily.
Set up once
Fix your wake time
Pick one wake time for all seven days and keep weekends within about an hour of it. Every other protocol on this page is timed from that one number.
Make the bedroom cool, dark and quiet
Lower the thermostat at night, block street light, and move the phone charger out of reach of the bed. Do it once and every night benefits.
Set your lights for the evening
Put a dim, warm lamp where you spend your evenings and stop using the overhead lights after dark. The goal is less light, and lower in the room, as bedtime gets closer.
Plan a week of movement
Block time in your calendar for resistance training, some cardio, walks on most days, and a few minutes of mobility. A plan that already has slots is easier to keep.
Check your basics before buying a supplement
Before you add anything, ask whether your sleep, light, movement and food are already in place. Talk to a doctor before starting anything new, especially if you take medication.
Every day
Get outside light in the first hour
Spend 5 to 10 minutes outdoors soon after waking, and longer on a grey day. A window is not enough. Never look straight at the sun.
Wait on caffeine, and stop it early
Have your first coffee an hour or two after waking rather than straight away, and have none in the 8 to 10 hours before bed.
Use one physiological sigh when stress spikes
Take two inhales through the nose, the second one on top of the first, then a long exhale through the mouth. One or two of these are usually enough.
Take a 10 to 20 minute rest in the afternoon
Lie down for a non-sleep deep rest or yoga nidra recording during the afternoon dip, instead of a third coffee.
Most of the levers are free, and most of them are a matter of when.HourLife note after Andrew Huberman Back to the library
