Huberman daily protocol: schedule & tracker

The Huberman daily protocol is a science-based daily routine designed to align your biology with natural circadian rhythms. Popularized by Stanford neurobiology professor Dr. Andrew Huberman on the Huberman Lab podcast, the routine centers on five foundational habits: viewing morning sunlight, delaying caffeine by 90 minutes, running a 90-minute focus block, taking an afternoon rest session, and dimming bright overhead lights at night.

The protocol centers on timing and physiology rather than punishing physical output. By aligning simple daily behaviors with your body's natural hormonal peaks, you improve daytime alertness, keep your energy steady without afternoon crashes, and fall asleep faster each night.

What is the Huberman daily protocol?

It is a collection of zero-cost behavioral habits arranged across five phases of the day: early morning, morning focus, afternoon reset, evening transition, and sleep. Each step relies on environmental cues like natural light, temperature shifts, and deliberate timing to signal to your nervous system when to produce alert hormones and when to wind down, without requiring expensive supplements or strict diets.

The foundation rests on five core habits:

1. Morning sunlight viewing: 10 to 20 minutes of natural outdoor light exposure within an hour of waking to set your circadian clock.
2. Delayed morning caffeine: Waiting 90 to 120 minutes after waking before your first cup of coffee or tea to prevent an afternoon energy crash.
3. 90-minute deep focus sprints: Working in focused blocks that match your brain's natural ultradian attention cycles.
4. Non-sleep deep rest (NSDR): A 10 to 20-minute guided relaxation session in the afternoon to restore dopamine and mental stamina.
5. Evening light hygiene: Dimming overhead lights and limiting screen exposure two hours before bedtime to protect natural melatonin release.

These behaviors work together as a 24-hour cycle. What you do in the first hour of the morning determines how well you produce melatonin 14 hours later, while your evening habits dictate how alert you feel the next day.

What does the daily schedule look like?

An ideal Huberman daily schedule follows a predictable chronological progression from waking through sleep. You can adjust the exact clock times based on when you wake up, but the relative intervals between waking, caffeine, meals, and wind-down remain constant.

Daily phase	Core habit	Duration	Biological goal
Early morning	Sunlight exposure	10 to 20 min	Set circadian clock
Mid-morning	Delayed caffeine	90–120 min post-wake	Clear morning adenosine
Morning focus	Deep work block	90 min sprint	Match ultradian cycle
Early afternoon	Restful NSDR	10 to 20 min	Restore striatal dopamine
Late evening	Dim ambient light	2 hours pre-bed	Protect melatonin release

Sample hourly schedule

• 6:00 AM – Wake up and hydrate: Drink 500 to 1,000 ml of water with a pinch of sea salt or electrolytes to reverse overnight dehydration.
• 6:15 AM – Morning sunlight viewing: Head outdoors for 5 to 10 minutes on clear sunny mornings, or 15 to 20 minutes if the sky is overcast.
• 6:45 AM – Physical movement or cold exposure: Complete your workout or take a 2 to 3-minute cold shower to elevate core body temperature and dopamine.
• 7:30 AM to 8:00 AM – First caffeine intake: Enjoy your first coffee or tea, at least 90 minutes after waking.
• 8:30 AM to 10:00 AM – Deep work block: Sit down for an uninterrupted 90-minute cognitive sprint on your most demanding project, with phone notifications silenced.
• 12:30 PM – First meal: Eat a light lunch centered on protein, healthy fats, and fiber to avoid post-lunch sluggishness.
• 2:00 PM to 2:30 PM – Afternoon NSDR session: Lie down and listen to a 10 to 20-minute guided NSDR or Yoga Nidra recording to recharge mental focus without grogginess.
• 6:30 PM – Dinner: Eat an evening meal containing complex carbohydrates like rice, potatoes, or oatmeal, which help deliver tryptophan to the brain to support sleep.
• 8:30 PM – Evening dim-down: Turn off bright overhead fixtures. Use low-placed lamps or warm amber lighting, and keep screens out of the bedroom.
• 10:00 PM – Sleep: Sleep in a cool, dark room, ideally kept between 65°F and 68°F (18°C to 20°C).

How does morning sunlight anchor your body clock?

Viewing morning sunlight sets your internal circadian clock by triggering a timed pulse of cortisol and dopamine. When natural photons enter your eyes, they strike specialized cells called intrinsically photosensitive retinal ganglion cells. These cells send an electrical signal directly to the suprachiasmatic nucleus, the master circadian clock located in your hypothalamus.

This signal triggers three biological events:

1. An immediate cortisol spike: While chronic cortisol is stressful, an early-morning cortisol pulse promotes sharp alertness and sets a timer for energy expenditure across the day.
2. A melatonin timer: The early-morning light signal starts an internal biochemical timer that triggers melatonin release approximately 12 to 16 hours later, allowing you to feel naturally sleepy at bedtime.
3. Circadian synchronization: Every organ and peripheral clock in your body aligns with this central light signal, improving digestion, temperature control, and mood.

To get the full effect, you have to step outside. Glass windows and car windshields filter out more than half of the blue and ultraviolet wavelengths your retinal cells need. On clear sunny mornings, 5 to 10 minutes of direct outdoor light delivers enough lux to trigger the cortisol pulse. On overcast mornings, light intensity drops sharply, so plan to stay outside for 15 to 20 minutes. Take your sunglasses off so the photons reach your retinas unobstructed, though standard prescription eyeglasses and contact lenses are fine because they don't block the necessary wavelengths.

Why should you delay caffeine by 90 minutes?

You should delay caffeine for 90 to 120 minutes after waking to let your body clear residual adenosine and prevent a mid-afternoon energy crash.

Every hour you stay awake, your brain metabolizes energy molecules and produces a chemical byproduct called adenosine. As adenosine builds up in your neural tissue, you feel gradual sleep pressure until deep sleep clears the backlog overnight.

When you wake up, a small amount of adenosine still lingers in your brain. Your body naturally flushes out this remaining residue as your morning cortisol peaks and you begin moving around.

Caffeine doesn't create new energy or eliminate adenosine. Instead, it acts as an adenosine receptor antagonist, docking inside those receptors and blocking adenosine from binding. If you drink coffee immediately after getting out of bed, caffeine occupies the receptors before your cortisol surge can clear that morning residue.

Four to six hours later, when your liver metabolizes the caffeine, that lingering morning adenosine joins the new adenosine you produced while working. Both hit your open receptors at once, triggering a sudden crash around 2:00 PM. Waiting 90 to 120 minutes gives your morning cortisol wave time to clear the slate, ensuring your coffee provides smooth, sustained focus without the afternoon drop.

When should you use NSDR and deliberate cold exposure?

You should use non-sleep deep rest (NSDR) during your afternoon energy lull and deliberate cold exposure early in the day to elevate sustained dopamine.

Non-sleep deep rest for mid-day recovery

Non-sleep deep rest is a term Dr. Huberman created to describe practices like Yoga Nidra and self-hypnosis that place your nervous system into deep physical relaxation while keeping your mind awake. A 10 to 20-minute NSDR session slows your brainwaves from active beta rhythms down to calm theta and delta waves.

A study in Experimental Brain Research showed that Yoga Nidra practice increases dopamine levels in the brain's ventral striatum by up to 65 percent. Listening to an NSDR audio session for 10 to 20 minutes around 1:00 PM or 2:00 PM restores mental stamina and resets working memory without the groggy sleep inertia of a traditional nap.

Deliberate cold exposure for mental resilience

Deliberate cold exposure, using cold showers or ice immersion, gives your sympathetic nervous system a sharp, controlled stimulus. Cold water triggers an immediate surge of norepinephrine and epinephrine, followed by a gradual, prolonged rise in baseline dopamine that lasts for hours.

A study led by Dr. Susanna Søberg found that a weekly threshold of 11 total minutes of cold water exposure, spread across two to four sessions, stimulates brown adipose tissue and increases metabolic rate. Because shivering and vascular constriction raise your core body temperature afterward, do your cold showers or plunge sessions in the morning or early afternoon so they don't interfere with your body's pre-sleep temperature drop.

How do you track the Huberman protocol in timespent?

You can track your entire routine in timespent, which includes a ready-to-use Andrew Huberman Arc in the app's Famous Routines templates. Instead of configuring separate apps for timers, cold showers, and habit tallies, loading the template sets up your daily protocols with a single tap.

You can track the protocol as an Unscripted Arc to build consistency across your waking hours without the pressure of a streak resetting if you miss a single cold shower. Use a Timed Activity for your morning sunlight and afternoon NSDR so your logged minutes show live on your Lock Screen. For your 90-minute morning deep work block, the built-in Interval Timer keeps you working in sync with your brain's natural ultradian rhythm. Simple Tallies record your caffeine delay and evening light dim-down with one tap.

Over time, your calendar heat map and Arc stats show your outdoor daylight hours, weekly cold exposure volume against the 11-minute target, and daily active days in one clean, ad-free view.

Frequently asked questions

Can you get morning sunlight through a window?

No. Window glass and automotive windshields block more than 50 percent of the relevant ultraviolet and blue light wavelengths that your retinal ganglion cells need to set your circadian clock. You need between 50 and 100 times more light exposure indoors to trigger the same biological response as standing outside. Step onto a balcony, porch, or sidewalk for five to ten minutes instead.

What should you do if you wake up before sunrise?

Turn on bright artificial lights throughout your home immediately, then step outside as soon as the sun rises. If you wake up hours before dawn or live in deep winter darkness, sit near a 10,000-lux daylight simulation lamp for 15 to 20 minutes while drinking your morning water, placing the lamp slightly above eye level to mimic the angle of morning sunlight.

Does drinking tea or decaf break the caffeine delay?

Caffeinated teas do, but decaf and herbal teas generally do not. Black tea, green tea, and matcha contain caffeine and block your adenosine receptors, so you should delay them for the full 90 to 120 minutes. High-quality decaf coffee has only trace caffeine (typically 2 to 5 mg per cup), which is low enough to let adenosine clear naturally. Herbal teas like chamomile or peppermint are completely caffeine-free and can be enjoyed right after waking.

How long does it take for the Huberman protocol to work?

Most people notice improvements in morning alertness and afternoon energy within three to five days of delaying caffeine and viewing sunlight consistently. Shifting your core circadian phase, where you consistently fall asleep faster at night and wake up without an alarm, typically takes 7 to 14 consecutive days of consistent morning light exposure and evening light dimming.
