Huberman's Protocols

Chapter 17: The Neuroscience (Why These Tools Work)

Andrew Huberman explains ADHD as fundamentally a dopamine problem — low baseline dopamine in the prefrontal cortex. Here's what that means practically:

Dopamine

• Controls the attentional spotlight — more dopamine = narrower, focused attention; less dopamine = wide, diffuse attention where everything is equally distracting
• Drives motivation and pursuit — it's what makes things feel worth doing
• Stimulant medications work by boosting dopamine to a functional threshold

Norepinephrine

• Amplifies the relevant signal — dopamine quiets background noise; norepinephrine boosts task-relevant information
• Together they create high signal-to-noise ratio — the brain state needed for directed focus

Acetylcholine

• Creates the "attentional spotlight" — the ability to narrow focus to a specific thing
• Trainable through visual focus exercises (see Chapter 19)

The Default Mode Network Problem

• The brain has two competing networks: the Task-Positive Network (focused work) and the Default Mode Network (daydreaming, mind-wandering).
• In non-ADHD brains, when you focus, the DMN quiets down. In ADHD brains, the DMN stays active — causing mental wandering even when you're trying hard.
• Dopamine in the PFC is the coordinator that tells the DMN to be quiet.
• Anything that raises dopamine helps with this — exercise, cold, medication, novelty.

Chapter 18: The Morning Protocol

Huberman's morning stack is the highest-leverage sequence for ADHD brains — it sets up the entire day's neurochemistry.

Step 1: Bright Outdoor Light (0–60 minutes after waking)

• Get 5–20 minutes of bright outdoor light within 30–60 minutes of waking
• Don't wear sunglasses (don't stare at the sun — just be outside or near a bright window)
• This sets the circadian clock, triggers a healthy cortisol spike (morning alertness), and primes dopamine pathways
• If natural light isn't available: a 10,000 lux light therapy lamp for 10–15 minutes

Step 2: Cold Exposure

• 1–3 minute cold shower immediately after or before morning light
• Cold exposure triggers a 250% (2.5x) increase in dopamine above baseline that lasts at least 2 hours
• Also significantly raises norepinephrine — the signal amplifier
• This dopamine is crash-free — it rises slowly, peaks, and sustains without a sharp drop

Step 3: Exercise (See Chapter 19)

• 20–45 minutes of cardio or resistance training after light + cold
• Raises dopamine, norepinephrine, and BDNF (brain fertilizer that strengthens neural connections)
• Even 20–30 minutes can produce several hours of improved focus — like an extra dose of focus

Protocol: Light → Cold → Exercise → Work. This sequence builds a neurochemical foundation before you sit down to do anything demanding.

Chapter 19: The Focus Protocol

Visual Focus Training — Huberman's Most Distinctive Tool

The visual system and attentional system share neural circuitry. Where your eyes go, your mind follows. You can use this to voluntarily enter focus.

• Find a single point at eye level — a dot on a wall, a spot on your desk
• Fix your gaze on it without moving your eyes for 30–60 seconds
• Notice your visual field narrowing as you lock in
• After the visual focus period, redirect attention to your task
• The attentional circuits primed by visual focus carry over to cognitive focus

Meditation — Reduces Attentional Blinks

People with ADHD have significantly more attentional blinks — brief lapses where the brain misses information. Even 15–20 minutes of quiet focused meditation reduces this.

• Sit quietly, close eyes, pay attention to your breathing for 15–20 minutes
• When your mind wanders, gently return to breathing — this IS the practice
• Done consistently, this rewires internal attention circuits

90-Minute Work Blocks

• The brain works in ~90-minute ultradian cycles — use these as your focus unit
• Use visual timers (Pomodoro style) to make time visible
• Shorter bursts (25 min) are fine if 90 minutes is too much initially
• Nasal breathing during focused work is associated with calmer, more sustained cognitive states

Physiological Sigh (Reset Tool)

When you feel scattered, anxious, or overstimulated — use this before trying to focus:

• Double inhale through the nose (short sniff, then top it off with more air)
• Long, slow exhale through the mouth
• Do this 1–3 times — fastest known way to activate the parasympathetic calm system

Chapter 20: Exercise Protocol for ADHD

"Exercise is the most important non-pharmacological intervention for ADHD."

— Andrew Huberman

Exercise addresses the underlying neurochemistry directly — not just the symptoms. It raises dopamine, norepinephrine, and BDNF, improving executive function directly.

What to Do

• Cardiovascular exercise (jogging, cycling, rowing, swimming) — primary recommendation, most studied for ADHD
• Resistance training — also raises dopamine/norepinephrine and supports focus
• High-novelty sports (martial arts, rock climbing, dance) are especially engaging for ADHD brains — require full attention

When to Do It

• Morning is ideal — the dopamine/norepinephrine surge sets up a better cognitive state for the rest of the day
• Even 20–30 minutes produces meaningful neurochemical shifts
• Do it BEFORE cognitively demanding work if possible

Combine with medication: If you take stimulant medication, combining it with exercise produces better long-term outcomes than either alone. Exercise strengthens the same circuits the medication is supporting.

Chapter 21: Sleep Protocol for ADHD

Sleep deprivation worsens every single ADHD symptom. Getting sleep right is foundational — nothing else works well on top of poor sleep.

Core Rules

• Consistent wake time every day — including weekends. This is the anchor of the entire system.
• Get into bed when you first feel sleepy — don't push through it
• Keep the bedroom cool: 60–67°F / 15–19°C
• Blackout curtains — any light during sleep disrupts circadian rhythm

Light Management (Free and Highly Effective)

• Morning: bright outdoor light within 30–60 minutes of waking (sets the clock forward)
• Afternoon: another outdoor light exposure around 4–6pm (reinforces the signal)
• Evening: dim all lights after 10pm; avoid overhead lights; use warm, low-positioned lamps
• No caffeine within 8–10 hours of bedtime

For Racing Thoughts at Bedtime

• Yoga Nidra / NSDR (Non-Sleep Deep Rest): 10–30 minutes of guided body scan — replenishes dopamine and calms the nervous system
• Boring, familiar audio: podcasts you've heard before, familiar shows with no visual stimulation
• Brain dump journaling: write out everything on your mind to "clear the buffer"
• 4-7-8 breathing: inhale 4 counts, hold 7, exhale 8

The ADHD Circadian Problem

• ADHD is associated with delayed circadian phase — the internal clock runs later than average.
• Many ADHD people physically cannot feel sleepy at a "normal" bedtime. This is biological, not a lifestyle choice.
• Morning bright light is the most effective intervention to shift this earlier.
• Weekend schedule drift undoes all progress — same wake time 7 days a week.

Chapter 22: Supplements for ADHD

These are adjuncts — not replacements for lifestyle tools or prescribed medication. Always consult a physician before starting.

Tier 1 — Best Evidence for ADHD

Omega-3 Fatty Acids (EPA-Dominant)

• 1–3g of EPA per day — this is the threshold for cognitive/attentional effects
• EPA is the key component (not DHA) for mood, focus, and ADHD
• At this dose, some adults with ADHD can function on lower medication doses
• Food sources: wild-caught salmon, mackerel, sardines, herring, anchovies

Phosphatidylserine

• 200mg/day — shown to reduce ADHD symptoms, especially combined with Omega-3

Zinc

• Plays a role in dopamine metabolism
• Studies show zinc alongside methylphenidate produced greater improvements in inattention
• 15–30mg/day if deficient — don't supplement if not deficient

Magnesium

• Magnesium Threonate (best for brain penetration) or Glycinate (best for sleep)
• 200–400mg elemental magnesium/day

Tier 2 — Additional Options

• L-Tyrosine (dopamine precursor) — start very low, titrate up; can cause jitteriness
• Caffeine — blocks adenosine, indirectly boosts dopamine; stop 8–10 hours before bed
• Alpha-GPC — supports acetylcholine (the attentional spotlight)

Chapter 23: Diet for ADHD

What to Remove / Reduce

• Simple sugars — spikes and crashes directly affect dopamine tone and attention
• Processed foods — broadly worsen ADHD symptoms
• Artificial food dyes and colorings — linked to attention problems especially in children

What to Prioritize

• Protein at every meal, especially breakfast — provides tyrosine (dopamine precursor); prevents the mid-morning attention crash from high-carb breakfasts
• Target 20–30g protein at breakfast: eggs, Greek yogurt, cottage cheese, protein shakes
• Omega-3 rich fish 2–3x/week: salmon, sardines, mackerel, herring
• Complex carbohydrates with stable blood sugar — avoids energy and attention crashes

The Sugar-Dopamine Loop

• ADHD brains with chronically low dopamine crave fast dopamine hits — and sugar is the fastest available.
• Sugar cravings are often a symptom of dopamine deficiency, not just habit.
• Strategy: have protein + fat available before the craving hits — the craving often passes once blood sugar stabilizes.
