Andrew Huberman's stack is a behavioral protocol built around the circadian clock: 5 to 10 minutes of morning outdoor light, delayed caffeine, Zone 2 cardio three to four times per week, a non-negotiable sleep routine with a consistent bedtime, brief cold exposure, and 10 to 20 minute NSDR sessions to recover focus. Most of it costs nothing and can be tracked through Apple HealthKit with LYF+.
Who is Andrew Huberman?
Andrew Huberman is an associate professor of neurobiology and ophthalmology at Stanford University School of Medicine. His laboratory has published peer-reviewed work on visual neuroscience, neural circuits for fear and stress, and the effects of light on the brain. Outside the lab, he is the host of the Huberman Lab podcast, one of the most widely listened-to science podcasts in the world, where he translates published research into practical protocols for sleep, focus, performance and longevity.
Unlike Bryan Johnson's Blueprint or David Sinclair's personal supplement stack, most of Huberman's recommendations are behavioral and free. They rest heavily on circadian biology and autonomic nervous system research — two fields with strong peer-reviewed support.
The morning stack
Huberman has repeated in dozens of episodes that the first 30 to 60 minutes after waking set the tone for the rest of the day. His morning stack is specifically designed to anchor the circadian clock and prime the nervous system for performance.
1. View morning sunlight within 30 minutes of waking
Huberman recommends stepping outside (not through a window) for 5 to 10 minutes on sunny days, 10 to 20 minutes on cloudy days, and up to 30 minutes on very overcast days. The goal is to get bright outdoor light into the eyes at the right time.
The biological rationale: outdoor light in the morning triggers a cortisol pulse that wakes you up, anchors the suprachiasmatic nucleus (the master circadian clock), and sets a timer for melatonin release roughly 14 to 16 hours later. Huberman frames this as the single highest-leverage habit for both sleep and daytime alertness, and the published circadian biology literature broadly supports that framing.
Do not skip this
If you adopt only one item from Huberman's stack, make it morning light. It costs nothing, takes 10 minutes, and has an outsized effect on your sleep that night.
2. Delay caffeine 90 to 120 minutes after waking
Huberman's reasoning: adenosine, the molecule that builds up during waking hours and creates "sleep pressure," is still elevated when you wake up. Caffeine blocks adenosine receptors, so drinking coffee immediately after waking masks the residual morning adenosine instead of letting it clear. The practical consequence, according to Huberman, is the afternoon crash that many coffee drinkers experience.
His protocol: drink water first, get outdoor light, then have your coffee roughly 90 to 120 minutes after waking. The recommendation is specific to morning coffee drinkers — not a universal rule.
3. Hydrate with electrolytes, not just water
Huberman emphasizes starting the day with water plus a pinch of sea salt or a dedicated electrolyte mix. The argument is that overnight sweating and respiratory losses deplete sodium, and plain water without electrolytes can actually worsen dilutional fatigue.
Exercise
Huberman's weekly exercise template, described across many podcast episodes, combines three modalities:
- Zone 2 cardio, 3 to 4 sessions per week, 30 to 45 minutes each — steady-state cardio at a pace where you can still hold a conversation. Zone 2 improves mitochondrial density and VO2 Max, which are among the strongest lifestyle predictors of longevity.
- Resistance training, 3 to 4 sessions per week — compound lifts for muscle mass preservation and metabolic health.
- High-intensity intervals, 1 short session per week — 4-6 minutes of hard effort broken into intervals to push the upper end of VO2 Max.
This roughly matches what cardiology and sports medicine literature recommend for healthy adults. It is also very close to the Blueprint and Sinclair exercise prescriptions, suggesting a rare point of consensus across all three longevity voices.
Cold exposure
Huberman has devoted multiple podcast episodes to the science of deliberate cold exposure. The practical takeaway from his synthesis of the published literature:
- A total of 11 minutes per week of genuine cold exposure, spread across 2-4 sessions, appears sufficient for the main metabolic and mood benefits.
- The cold must be uncomfortable but safe — a cold shower cold enough that you would want to exit is about right.
- End showers on cold, not hot, for the neurochemical boost.
The sleep stack
Huberman treats sleep as the non-negotiable foundation of everything else. His sleep routine is as structured as his morning one.
Behavioral protocol
- Consistent bedtime and wake time, even on weekends, with a variance of 30 minutes or less.
- Dim lights in your environment in the two hours before bed (especially overhead lights).
- Cool the room to around 60-67°F (16-19°C).
- Avoid bright screens in the last hour before bed, or use blue-light-reducing modes if you must use them.
- Avoid caffeine after roughly 2 PM (caffeine has a half-life of 5-6 hours, meaning a lot is still in your system at bedtime).
Sleep supplement stack
Huberman has publicly discussed a specific supplement stack he takes 30 to 60 minutes before bed, including magnesium threonate, apigenin, and L-theanine. He has emphasized that this is his personal experimentation based on the published literature on these compounds and is not a universal recommendation. LYF+ does not track or recommend supplements.
Important
Supplements interact with medications and individual physiology. The right stack — if any — depends on your personal situation. Consult a qualified physician before experimenting with sleep supplements, and do not assume that what works for a Stanford professor will work for you.
NSDR (Non-Sleep Deep Rest)
NSDR is a term Huberman has popularized for guided protocols (in the Yoga Nidra tradition) that deliberately lower arousal while keeping you awake. A 10 to 20 minute NSDR session, typically in the afternoon, can restore focus and support learning consolidation. Huberman has argued that NSDR is a tool to compensate for partial sleep loss — not a substitute for sleep, but a supportive practice you can add to any day.
What LYF+ tracks from the Huberman stack
Huberman's stack is unusually aligned with what LYF+ measures. Many of its key habits map directly onto the app's four pillars, which is why the Huberman Stack is often the recommended protocol in LYF+ for beginners.
| Huberman habit | LYF+ pillar | What you see in the app |
|---|---|---|
| Consistent bedtime | Regularity (10%) | Bedtime stability graph |
| 8+ hours of sleep | Sleep (35%) | Daily sleep score, trend |
| Zone 2 cardio, daily walking | Activity (30%) | Step count, optimal zone gauge |
| Cold exposure, recovery | Recovery (25%) | HRV and resting HR trend |

Is the Huberman stack right for you?
Of the three longevity protocols covered in this content hub, the Huberman Stack is the most approachable for beginners. Most of it is free, behavioral, and backed by published peer-reviewed research. Morning light, delayed caffeine, consistent bedtime, and Zone 2 cardio are all low-risk habits with meaningful downstream effects on sleep, metabolic health, and cognitive function.
The Blueprint and Sinclair protocols contain more experimental elements. The Huberman stack contains fewer — and that is an advantage if you want to start building a longevity practice without signing up for supplement subscriptions or complicated fasting schedules.
That is also why LYF+ recommends the Huberman Stack by default for users who are new to longevity tracking: the behavioral core is exactly what LYF+ measures, and the ramp-up is gentle.
