Huberman Sleep Protocol: The Complete Canadian Guide

Reading Time: 10 minutes

If you have spent any time looking into sleep science, you have probably come across Dr. Andrew Huberman's sleep toolkit. The Stanford neuroscientist has distilled decades of circadian biology research into a practical daily protocol that millions of people now follow. Some of it is genuinely helpful. Some of it needs context. And some of it needs adjusting if you live in Canada, where winter mornings are dark until 8 a.m. and summer evenings stay bright past 9:30.

We hear about Huberman's protocol regularly at our Brantford showroom. Customers walk in already doing the morning sunlight walks, already taking magnesium before bed, already dimming their lights at 8 p.m. What they often have not addressed is the surface they are sleeping on, which matters more than any supplement stack.

Here is the full Huberman sleep protocol, what the research actually says, and how to make it work in Ontario.

What Is the Huberman Sleep Protocol?

Dr. Andrew Huberman is a professor of neurobiology and ophthalmology at Stanford University School of Medicine. His Huberman Lab podcast, launched in 2021, covers neuroscience-based tools for everyday life, with sleep optimization being one of his most popular topics.

The protocol is not a single trick. It is a system built on five interconnected pillars:

1. Light exposure timing (morning bright light, evening dim light)
2. Temperature regulation (cool bedroom, warm body before bed)
3. Consistent sleep-wake schedule (same times daily, including weekends)
4. Caffeine and stimulant management (none within 8 to 10 hours of bedtime)
5. Targeted supplementation (magnesium, L-theanine, apigenin)

The Morning Light Protocol

This is the foundation of everything else in the Huberman sleep protocol. Within 30 to 60 minutes of waking, get outside and look toward the sky (never directly at the sun) for 2 to 10 minutes. On overcast days, you may need 15 to 30 minutes.

The purpose is simple. Bright natural light, even on a cloudy day, delivers 10,000 to 50,000 lux of illumination. Your brightest indoor lights produce maybe 500 lux. The difference is enormous, and your circadian clock needs that intensity to properly calibrate.

What This Does Physiologically

• Triggers a cortisol pulse that promotes alertness (this is healthy, not stress-related)
• Starts a 12 to 14-hour countdown to natural melatonin release
• Sets your internal temperature rhythm for the day
• Improves mood through serotonin pathway activation

Huberman also recommends a second light viewing session in the late afternoon, around sunset, for 5 to 10 minutes. This sends a "transitional" signal to your SCN that darkness is approaching.

Temperature and Bedroom Setup

Your core body temperature needs to drop by about 1 to 1.5°C for sleep onset. Huberman recommends keeping your bedroom at approximately 18°C (65°F), which aligns with research published by Okamoto-Mizuno and Mizuno (2012) in the Journal of Physiological Anthropology showing that the optimal sleeping temperature range is 15.6 to 19.4°C.

Your Mattress Is Part of the Temperature Equation

Something Huberman rarely discusses is the role of the mattress itself in temperature regulation. If you are sleeping on an older foam mattress that traps heat, no amount of thermostat adjustment will compensate. At our Brantford showroom, Brad sees this pattern constantly: customers following every biohacking protocol but still waking up sweating because their ten-year-old mattress has lost its breathability.

A mattress with individually wrapped coils allows air circulation underneath and between layers. The Restonic ComfortCare Queen, for example, has 1,222 individually wrapped coils at $1,619, offering both support and the airflow that temperature-focused sleepers need.

The Huberman Sleep Supplement Stack

Huberman takes three supplements nightly, about 30 to 60 minutes before bed:

1. Magnesium L-threonate (145 mg) or Magnesium Bisglycinate (200 mg): Both forms cross the blood-brain barrier more effectively than magnesium oxide or citrate. Research by Abbasi et al. (2012) in the Journal of Research in Medical Sciences found that magnesium supplementation significantly improved subjective sleep quality in elderly participants with insomnia.
2. L-Theanine (100 to 400 mg): An amino acid found in green tea. Promotes alpha brain wave activity associated with calm wakefulness. Huberman notes this can cause vivid dreams in some people and should be avoided by sleepwalkers.
3. Apigenin (50 mg): A flavonoid found in chamomile. Acts as a mild sedative by binding to GABA receptors. It is difficult to say whether 50 mg of isolated apigenin works better than simply drinking chamomile tea, but the standardized dose allows consistency.

He rotates in glycine (2g) and GABA (100 mg) a few times per week, and uses myo-inositol (900 mg) for people who wake in the middle of the night and struggle to fall back asleep.

Evening Wind-Down Routine

Between 8 and 10 p.m., Huberman follows a systematic wind-down:

• Dim all overhead lights. Use low-positioned floor lamps or candles if possible
• Avoid screens, or use blue-light blocking glasses if screens are necessary
• Lower the room temperature by 1 to 2 degrees from daytime settings
• No food within 2 to 3 hours of sleep (large meals delay sleep onset)
• Consider a self-hypnosis or sleep meditation session (he recommends the Reveri app)

The key principle: bright light between 10 p.m. and 4 a.m. disrupts the dopamine system and can shift circadian phase in ways that take days to correct. Even brief bathroom light exposure can suppress melatonin production for up to 45 minutes.

Caffeine and Stimulant Rules

Huberman delays his first coffee until 90 to 120 minutes after waking. This allows the natural cortisol awakening response to peak without interference. He then avoids all caffeine within 8 to 10 hours of bedtime, meaning a 10 p.m. sleeper would stop caffeine by noon to 2 p.m.

For Canadians who rely on their Tim Hortons run, this is often the hardest part of the protocol. The afternoon coffee that gets you through a January workday may be the reason you are staring at the ceiling at midnight.

Adapting the Huberman Protocol for Canadian Seasons

Seasonal Adjustments

• Winter (November to March): Use a 10,000-lux light therapy box within 30 minutes of waking. Keep it at arm's length for 20 to 30 minutes. This replaces the outdoor sunlight that is not available. Get outdoor light at lunch if possible.
• Summer (May to August): Blackout curtains become essential. When the sun sets at 9:15 p.m. and twilight lingers past 10, your brain gets mixed signals. Heavy blackout curtains or a quality sleep mask help simulate darkness.
• Spring and Fall: The transitional seasons are actually ideal for the protocol. Moderate daylight hours align well with typical work schedules.

Temperature Differences in Ontario Homes

Ontario winters mean forced-air heating, which creates two problems: dry air and inconsistent room temperature. A bedroom above a garage will be colder than one over the kitchen. The 18°C recommendation may need adjustment based on your specific room. In our experience, the best approach is to keep the thermostat at 17 to 18°C overnight and use a quality duvet system where you can add or remove layers.

What the Huberman Protocol Does Not Address

For all its strengths, the protocol has gaps:

• Sleep surface quality: You can follow every light, temperature, and supplement recommendation, but if your mattress sags in the middle or your pillow forces your neck into a strange angle, none of it compensates. The Sleep Foundation recommends replacing mattresses every 7 to 10 years.
• Individual variation: Chronotypes differ. The protocol assumes a relatively standard schedule, but night owls and light sleepers may need modifications.
• Cost: The full supplement stack runs $60 to $120/month in Canada. A quality mattress, while a larger upfront investment, lasts 7 to 10 years and addresses the physical foundation that supplements cannot.
• Sleep disorders: The protocol is designed for healthy individuals looking to optimize. If you have sleep apnoea, restless legs, or chronic insomnia, see a sleep specialist before adding supplements.
