Short answer: Dr Andrew Huberman’s full daily routine is a circadian-anchored protocol. You get outdoor morning sunlight for 5–30 minutes within 30–60 minutes of waking, delay caffeine 90–120 minutes, train in deliberate cold 2–5 minutes three times a week, take an NSDR (Non-Sleep Deep Rest) break in the afternoon, work in 90-minute ultradian blocks, and dim bright lights after sunset. Cold bedroom, blackout, no caffeine after 14:00. Verified against Huberman Lab Episodes #2, #37, and the Stanford Neuroscience Laboratory; structured into 30 numbered actions inside the Protocols app under blueprint PROT_001.
Why the Huberman protocol matters
Andrew Huberman is a tenured professor of neurobiology at Stanford School of Medicine and host of the Huberman Lab podcast. Across more than 200 episodes he has published a practical framework for managing the nervous system using cheap, zero-pharmacological tools — most of which are circadian engineering: light, temperature, breath, and timing.
Two features separate his protocol from generic “morning routine” content:
- Each action is tied to a specific physiological gate. Morning light hits retinal ipRGCs → suprachiasmatic nucleus → cortisol pulse; delayed caffeine waits for adenosine clearance; cold exposure exploits norepinephrine’s 200–300% spike. This is biochemistry, not aesthetic.
- Each action has a measurable effort and cost. In the Protocols database, Huberman’s blueprint scores an average 4.4/5 on scientific evidence across 30 actions. That is the difference between “tried it once” and “system that’s been engineered against the biology.”
If you adopt the protocol as written, you recover roughly 15–20 minutes per day by stacking low-effort habits (sunlight + optic flow walk + hydration). The friction engine in our protocol builder does that math automatically. The deep dive behind that number is in Habit Stacking & Willpower Friction.
The science: light, adenosine, and hormetic stress
Three mechanisms carry most of the protocol.
Circadian anchoring. Light that lands on intrinsically photosensitive retinal ganglion cells (ipRGCs) within 30–60 minutes of waking synchronises the suprachiasmatic nucleus (SCN), your body’s master clock. The SCN does three things in response: it triggers a controlled cortisol rise (alertness), starts a 12–14-hour countdown to melatonin, and upregulates dopamine receptor density in the striatum. Skip the signal and your body runs ~1.5–2 hours late — observable as evening insomnia and groggy mornings.
Adenosine clearance. Adenosine is the metabolic pressure that drives sleepiness. Caffeine blocks adenosine receptors, but the receptors are still occupied by residual adenosine for ~90–120 minutes after waking. If you drink coffee immediately, you mask the rising pressure instead of letting it disperse; an afternoon crash follows. Delaying caffeine by ~90 minutes lets adenosine fall to baseline, then caffeine blocks fresh receptors more cleanly.
Hormetic stress. Brief cold (≤11 min/week total, according to Huberman) raises norepinephrine 200–300% in some studies and dopamine ~250%. Heat (sauna 20 min ~80–100°C) elevates heat-shock proteins (HSP70), which chaperone misfolded proteins. Both work via short, controlled stress that upregulates recovery systems — same way weight training builds muscle. We cover the cold layer in depth in Wim Hof Method: Breath, Cold & the Science.
The step-by-step daily protocol
Numbers reference action IDs in the Protocols app; figures are the durations and effort scores stored in the database. Effort runs 1 (essentially automatic) to 5 (severe); cost runs 0–3 (zero = free). Build this routine by adding the listed actions to your Everyday baseline in the order below.
Morning block
- Consistent wake time (
ACT_015, effort 3, evidence 5). Same wake time daily — even weekends — to lock the SCN. Choose a time you can defend. - Morning sunlight (
ACT_001, 10–30 min, effort 1, evidence 5). Outdoors, no tinted glasses. Clear sun: 5–10 min. Overcast: 15–25 min. Heavy cloud: up to 30 min. Look toward the sun, not directly into it. - Optic Flow Walk (
ACT_003, 15–30 min, effort 1, evidence 4). Walk while letting your gaze flow forward. Stacks with sunlight; the app marks the two as STACKED. - Morning hydration + salt (
ACT_005, 2–5 min, effort 1, evidence 4). About 500 ml of water with a pinch of salt on rising; blood volume drops overnight and the brain misreads dehydration as fatigue. - Delay caffeine 90–120 min (
ACT_004, effort 2, evidence 4). First coffee lands around 9:00 if you wake at 7:00. Use water, a walk, or a 5-min breath cycle instead. - Box breathing or physiological sigh (
ACT_111/ACT_007, 1–5 min, effort 2, evidence 5). The “physiological sigh” — two quick inhales through the nose followed by a long exhale — drops acute stress in under a minute. Use it before any high-friction task. - Heavy compound strength or Zone 2 (
ACT_030,ACT_032; evidence 5). Strength days: 45–60 min, 3–5 heavy lifts, 6–12 reps. Zone 2 days: 45–60 min at conversational pace.
Midday and focus block
- Ultradian 90/20 deep work (
ACT_086, 90 min, effort 3, evidence 4). Single-task block; email off; one-tap begin in the Today timeline. - NSDR / Yoga Nidra (
ACT_008, 15–30 min afternoon, effort 1, evidence 4). Non-Sleep Deep Rest: lie down, follow a guided protocol for 10–30 minutes, drift but stay awake. Resets adenosine and dopamine baseline. - Caffeine cutoff at 14:00 (
ACT_096, effort 2, evidence 5). Hard line. After 14:00: water, electrolytes, decaf only. - Power nap max 20 min (
ACT_012, evidence 4). Only if you can’t do NSDR. Anything longer triggers slow-wave sleep and grogginess.
Evening block
- Mouth taping (
ACT_095, evidence 4). Optional but high evidence for nose-only breathing; reduces snoring and mild sleep-apnoea events. - Magnesium + glycine (
ACT_083/ACT_037, evidence 4). Around 30 min before bed. - Dim lights after sunset (
ACT_013, 120–180 min, effort 2, evidence 5). No overhead LEDs after dinner; warm lamps only. Lower lux at the eye is the goal, not zero light. - Cool bedroom 18°C + blackout (
ACT_014, evidence 5). Core temperature must drop for sleep onset; a 18°C room and blackout curtains support that. - Post-dinner 15-min walk (
ACT_120, effort 1, evidence 5). Improves glucose disposal, reduces late-evening cortisol. - Alcohol abstinence or strict minimum (
ACT_097, effort 3, evidence 5). Alcohol fragments REM and worsens sleep architecture. If you drink, stop 3 hours before bed.

Common mistakes that ruin the protocol
- Tinted sunglasses or window glass in the first hour. Both block the wavelengths ipRGCs respond to. Step outside, take them off.
- Morning coffee before 9:00. You’ll mask the rising adenosine and crash at 14:00 instead of riding a stable curve.
- Skipping weekends. “Catch-up sleep” doesn’t reset circadian phase; inconsistent wake times shift SCN by ~1 hour per week. Pick a wake time you can keep Monday through Sunday.
- Cold exposure right after waking. Adds mood boost but raises cortisol 200–300%; people sensitive to anxiety should schedule cold later in the morning, not in the first hour.
- Pairing NSDR with deep work after caffeine. NSDR is most effective when adenosine is climbing (mid-afternoon), not 30 min after a 200 mg caffeine dose.
How to start tomorrow morning
Do not boil the ocean. Take these four actions on day one — they are free, friction-free, and stack:
ACT_001Morning sunlight — 10 minutes outside, no tinted sunglasses.ACT_003Optic Flow Walk — same 10 minutes; counts as sunlight.ACT_005Hydration + salt — 500 ml water + pinch of salt on rising.ACT_004Delay caffeine 90–120 min — first coffee at 9:00 if you wake at 7:00.
After one week, add ACT_096 (caffeine cutoff 14:00). After two weeks, add ACT_008 NSDR. Cold exposure, mouth taping, magnesium, and sleep-stack supplements come later. This sequencing is what gets a Huberman protocol to stick.
Quick answers
Do I really need to go outside?
Yes. Standard window glass filters ~80% of the wavelengths ipRGCs respond to and reduces intensity ~50×. A balcony or an open window where unfiltered sky light enters the eye works; nothing else does.
What if I wake before sunrise?
Use a 10,000-lux therapy lamp for 6–10 minutes (ACT_017 in the Protocols library), then go outside when the sun clears the horizon.
Is Huberman’s protocol safe with medications?
Some elements interact with cardiovascular or psychiatric medications (deliberate cold, mouth taping, breath holds). Check with your physician before layering these onto an existing regimen.
How to build this routine in Protocols
Open the Protocols Builder, drag ACT_001 Morning Sunlight and ACT_003 Optic Flow Walk onto your Everyday baseline; the app flags them STACKED so you recover ~15–20 min every morning. Add ACT_004 Delay Caffeine and ACT_096 Caffeine Cutoff 14:00 to bracket your caffeine window. Then layer in NSDR, evening light dimming, and the cool-bedroom block. The friction engine will recalculate your day-friction score live so you don’t burn out by stacking too many effort-5 actions back-to-back.
