Dr Andrew Huberman: The One Daily Practice Everyone Should Do, Training Your Brain and Reducing Anxiety #227

CAUTION: Contains themes of an adult nature. If I told you there was a simple, free habit you could take up to optimise your health in just five to 10 minutes a day, would you be up for trying it? If the answer’s yes, then you’re going to love today’s guest, a brilliant science communicator who reveals what the habit is – and shares ground-breaking insights from his research.   Dr. Andrew Huberman is a professor of neuroscience at Stanford University School of Medicine in the US and he has made numerous contributions to the fields of brain development, brain function and neuroplasticity. His lab’s most recent work focuses on the influence of vision and breathing on human performance and brain states such as fear and courage. His work has been published in top scientific journals including Nature, Science, and Cell and has been featured in global media outlets such as TIME magazine, BBC, and Scientific American.   We begin this conversation discussing why exposure to morning light is key to optimum human functioning. Our visual system is about more than just seeing. The light that enters our eyes, even in blind people, gives knowledge to the nervous system. Getting the right light, at the right time, sets the clock in all of your body’s cells, which in turn will affect many different functions in the body. It stimulates the cortisol you need for energy and focus. And it has positive effects on everything from sleep, energy and immunity to appetite, mood and so much more.    We also discuss what exactly is going on in the brain when we feel fearful and how something as simple as getting outside and looking at the horizon can completely change our physiology and powerfully inhibit anxiety.   Finally, we talk about the role that technology is having on our attention and Andrew shares a variety of simple exercises that we can all do to train our brains to improve our focus, health and performance.   Andrew is a special human being and someone who I have been wanting to speak to for a long, long time. I really enjoyed speaking to him - I hope you enjoy listening. Thanks to our
Actionable Insights

1. Coordinate Body Clocks with Light

Ensure light arrives at your eyes at appropriate times of day and is absent at other times to coordinate all cells and systems of your body, as disruptions are linked to various health issues including digestive, mental focus, depression, and anxiety.

2. Morning Sunlight Exposure

View bright light, ideally sunlight, for 5-10 minutes (or longer on overcast days) within 30-60 minutes of waking, without sunglasses or through windows, to set your body’s master circadian clock, boost morning cortisol for energy and focus, and improve sleep quality later that night.

3. Dim Evening Lights

Dim lights in the evening and late hours, especially between 10 p.m. and 4 a.m., and avoid bright screens, as retinal sensitivity increases at night, and even low light can disrupt melatonin release and your circadian rhythm.

4. Physiological Sigh for Stress

When feeling stressed or anxious, perform a physiological sigh by taking two quick, deep inhales through the nose back-to-back, followed by a long, complete exhale through the mouth, to immediately reduce stress by re-inflating lung alveoli and offloading carbon dioxide.

5. Expand to Panoramic Vision

Practice panoramic vision by dilating your gaze to see more of the space around you without moving your head or eyes, which has a relaxing effect, reduces stress, and enhances situational awareness and reaction times.

6. View Distant Objects Daily

Periodically view objects in the distance, beyond screens or walls, ideally a horizon, to reduce eye strain, prevent myopia, improve mood, and enhance metabolic function.

7. Self-Generated Optic Flow

Engage in self-generated forward motion like walking, jogging, or biking outdoors without staring at your phone, as the visual world slipping by powerfully inhibits the brain’s threat reflex and reduces anxiety.

8. Take Short Focus Breaks

Incorporate 10-second micro-breaks during high-attentional activities (learning, deep work) to allow the brain to store information faster, decompress, and return with heightened focus.

9. Train Visual Focus

To improve concentration, place a small target (e.g., a crosshatch on paper) at your computer’s distance and focus your vision on it, blinking as seldom as possible for about 60 seconds, to adjust your visual and mental focus.

10. Huberman’s Morning Visual Training

Practice a sequence of visual focus: close eyes and focus internally (3 breaths), open eyes and focus on hand (3 breaths), focus on a distant object (3 breaths), panoramic vision (3 breaths), then return to internal focus and a crosshatch, to train your system for better transitions and focus throughout the day.

11. Intentional Nervous System Training

Deliberately engage in practices that force specific changes onto your nervous system, rather than letting passive living dictate its changes, to leverage its capacity for positive adaptation and build resilience.

12. Action Over Thoughts/Feelings

Prioritize physical actions and behaviors to influence your mental and physical health and performance, especially when overwhelmed, as physical practices provide concrete tools to recalibrate your state of mind.

13. Cold Exposure for Immunity

Engage in deliberate cold showers for three minutes every two or three days, or practice cyclic hyperventilation, to cause adrenaline release which strengthens the immune system and increases resistance to infections.

14. Magnesium & Apigenin for Sleep

If struggling with sleep, consider taking magnesium threonate or bisglycinate, and 50 milligrams of apigenin (chamomile extract), as these non-addictive supplements can help improve sleep onset and duration.

15. Yoga Nidra / NSDR for Sleep

Utilize Yoga Nidra (a 30-minute script) or the Reveri.com self-hypnosis app, both free resources, as non-sleep deep rest (NSDR) practices to improve your ability to fall asleep or return to sleep if you wake up at night.

16. EPA for Mood & Antidepressant Effect

Supplement with one to three grams of EPA essential fatty acids daily, especially if you don’t consume fatty fish, as 1-2 grams of EPA has shown antidepressant effects comparable to SSRIs and can lower the required dosage of such medications.

17. Fermented Foods for Gut Health

Consume one to four servings of fermented foods daily to improve your gut microbiome and reduce inflammatory pathways, supporting overall health.

18. Scientific Supplement Experimentation

Approach supplement use scientifically by introducing new compounds one at a time, observing their effects, and consulting a physician, rather than taking many at once, to determine what works best for your individual needs.

19. Journaling for Emotional Release

Engage in daily journaling, even if informal, to externalize anxieties and stresses onto paper, which can help expunge them and provide mental relief.

20. Filter Interactions with Empathy

When encountering aggressive or concerning comments, especially online, filter them through the understanding that many people struggle with mental health challenges, which can help prevent personal triggering and foster a more compassionate perspective.

21. Use Ring Light for Morning Light

As a low-cost alternative to sunlight when unavailable, use a blue ring light (like those used by YouTubers) at your breakfast table or while working in the morning to stimulate your circadian system.

22. Kids’ Screen & Myopia Prevention

For children, dim screens, keep room lights low, and remove phones/tablets from rooms at night; also encourage two hours of outdoor time daily (even with homework) to significantly reduce the incidence of nearsightedness (myopia).

23. Exercise Outdoors Without Sunglasses

If you exercise, try to do it outside without sunglasses to maximize the benefits of natural light exposure on your visual system and overall well-being.
