Dr. Matt Walker: How to Structure Your Sleep, Use Naps & Time Caffeine | Huberman Lab Guest Series

Andrew Huberman

Apr 17, 2024

Episode description

This is episode 3 of a 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley, and leading public educator about the role of sleep in health, disease and performance.

We explain how our sleep architecture changes as we age. We also cover how childhood development and aging affect sleep biology and needs. We also discuss whether polyphasic sleep (multiple short sleep periods) is beneficial.

Then, we discuss naps, including their positive benefits, individual variability, those who should not nap, and alternative rest states like non-sleep deep rest. Dr. Walker shares protocols to optimize nap duration, timing and effectiveness.

We also explore the effects of caffeine on sleep and other health aspects, as well as the optimal timing for caffeine intake.

This episode describes many actionable science-based tools for optimizing sleep, naps and caffeine use for better health and performance.

The next episode in this special series explores the relationship between sleep, memory, and creativity.

Mindsip insights from this episode:

Leverage chronotypes as a survival advantage for group safety

The genetic variation in sleep timing preferences is an evolutionary advantage that ensures someone in a group is always awake, reducing collective vulnerability.

Avoid late caffeine to protect deep sleep quality

Even if you can fall asleep after drinking caffeine late at night, it can reduce your deep sleep by up to 20%, which you won't be aware of but will leave you feeling less refreshed.

Try the Nappuccino for enhanced energy and alertness

The "Nappuccino" involves drinking a quick espresso immediately before a 20-minute nap to wake up with the combined benefits of sleep and caffeine, while avoiding sleep inertia.

Address fragmented sleep to reduce frequent napping in older adults

Frequent napping in older adults is linked to worse health outcomes not because naps are inherently bad, but because they are a reflection of poor quality, fragmented sleep at night.

Utilize meditation for local sleep benefits

Restorative practices like meditation or Non-Sleep Deep Rest (NSDR) may work by inducing "local sleep," where parts of your brain enter a deep sleep state even while you remain consciously awake.

Take a 20-minute nap for alertness boost

For a quick boost in alertness and concentration without the grogginess of sleep inertia, the optimal nap duration is about 20 minutes.

Utilize naps to reset emotional balance

Napping has the ability to reset your emotional compass by lessening your sensitivity to negative emotions like fear and anger while boosting how positively you rate happy faces.

Lie down to cool your core and initiate sleep

Lying horizontally makes you sleepy because it is the optimal position for your body to move blood to the surface and release heat, which lowers your core body temperature and initiates sleep.

Avoid adult polyphasic sleep to protect cognition and health

Contrary to claims in some biohacking circles, scientific evidence shows that adult polyphasic sleep schedules do not improve performance and are detrimental to cognition, mood, and metabolic health.

Maximize nap benefits with caffeine, cold water, and bright light

To maximize the benefits of a nap, you can "stack" interventions by having caffeine before, followed by cold water on the face and hands and bright light exposure immediately upon waking.
