BITESIZE | Do This Every Day to Reduce Stress and Anxiety and Improve Focus | Dr Andrew Huberman #421
Dr. Andrew Huberman, a Stanford neuroscientist, shares powerful, zero-cost tools leveraging the visual system to reduce stress, improve focus, and enhance performance. He explains how specific visual practices can calm the mind, sharpen attention, and train the brain for better transitions in a modern, distraction-filled world.

5 Key Concepts
Visual System's Role
The visual system, including the eyes and neural retina, is a unique part of the central nervous system located outside the cranial vault. It serves as the primary way the nervous system gathers information about external circumstances and coordinates all bodily functions, making it a powerful tool for mental and physical health.
Panoramic Vision
This is a mode of vision where you consciously dilate your gaze to perceive more of your surroundings without moving your head or eyes. It has a relaxing effect, decelerates stress, increases situational awareness, and improves reaction times by engaging specific magnocellular neurons in the eye and brain.
Cognitive Focus Follows Visual Focus
This principle states that your mental or cognitive ability to concentrate is directly linked to and can be trained by controlling your visual attention. By deliberately narrowing or expanding your visual field, you can influence and improve your capacity for mental focus.
Context Switching
Refers to the rapid and frequent shifting of attention between different tasks, stimuli, or information sources, often driven by modern technologies like smartphones and social media. This constant switching is something the human brain is not evolved to handle and can deplete focus and attention capacity.
Neuroplasticity
The nervous system's inherent ability to change and reorganize itself in response to experience. This capacity can be deliberately leveraged through specific practices to improve mental and physical function, or it can lead to detrimental changes if exposed to unhelpful passive stimuli like excessive screen time or lack of movement.
7 Questions Answered
The visual system is unique because it's the only part of the central nervous system outside the cranial vault, acting as the primary way the brain gathers information about the external world and coordinates all bodily functions.
By practicing panoramic vision, where you dilate your gaze to see more of your surroundings without moving your head or eyes, you can trigger a relaxing effect and decelerate your stress response.
Panoramic vision, by engaging magnocellular neurons, makes you more situationally aware and can increase your reaction times about fourfold, rather than making you tune out.
Since cognitive focus follows visual focus, you can train your brain to concentrate better by consciously narrowing your visual attention, for example, by focusing intently on a small point for about 60 seconds.
These devices constantly force rapid 'context switching' by bombarding us with new information and stimuli, which the human brain is not evolved to handle and leads to a depletion of our focus and attention capacity.
Even brief 10-second pauses during high-attentional activities allow the brain to store information faster, decompress, and then return to activity with a heightened level of focus.
Yes, by systematically practicing shifting your visual attention between different 'space-time bins' (e.g., internal state, near focus, far focus, panoramic vision), you can train your nervous system to transition more effectively between tasks and maintain deep focus.
10 Actionable Insights
1. Daily Visual Training Meditation
Practice a daily visual training meditation by systematically shifting your visual attention: close eyes for 3 breaths (interoception), focus on hand at arm’s length for 3 breaths, look into the distance for 3 breaths, engage panoramic vision for 3 breaths, return to internal landscape, then focus on a crosshatch before starting work. This trains your system to adjust to shifts, improving transitions and focus throughout the day.
2. Use Panoramic Vision to Relax
To relax and decelerate stress, expand your visual field without moving your head or eyes, trying to see more of the space around you, including your own body in peripheral vision. This covert technique releases a brain-brain stem connection, having a relaxing effect on your system.
3. Improve Focus with Visual Anchor
To improve cognitive focus before work, place a piece of paper with a crosshatch at computer distance, then force your vision to focus on it for about 60 seconds, blinking as seldom as possible. This adjusts your visual and mental aperture, helping to rule out distractions.
4. Integrate Short Micro-Breaks
Integrate short, even 10-second pauses into your day, especially during high attentional activities. These micro-breaks allow the brain to store information faster, decompress the system, and heighten focus when you return to activity.
5. Enhance Awareness with Panoramic Vision
Engage panoramic vision to become more alert, aware, and responsive, as it can increase reaction times about fourfold. This technique enhances situational awareness without tuning out, making you more effective in monitoring your environment.
6. Actively Shape Nervous System
Deliberately force specific, positive changes onto your nervous system through practices like visual training, rather than allowing passive consequences of modern living (e.g., excessive light at night, lack of sunlight/movement) to change it for the worse.
7. Balance Focus with Rest
For effective learning and performance, balance periods of intense focus with deliberate periods of rest. Neuroplasticity, the nervous system’s ability to change, requires both leaning in with focus and leaning out to access rest.
8. Limit Passive Context Switching
Avoid excessive passive context switching, such as rapidly scrolling through social media, as the human brain is not evolved to contend with constant bombardment of new contexts. This practice helps prevent self-induced ADHD and improves focus.
9. Limit “Soda Straw” Phone Vision
Avoid constantly looking into the narrow “soda straw” view of your phone, as this drives attentional mechanisms and stress levels up. Instead, use micro-breaks or panoramic vision to allow your system to relax.
10. Manage Focus Judiciously
Be judicious in your use of focus and attention throughout the day, as constantly expending it on small tasks without breaks can deplete your capacity for deep work.

The visual system is unique in that it's the only piece of the central nervous system that resides outside the cranial vault.
Dr. Andrew Huberman
Vision, as you recall, is the brain. So it's the fastest route by which we can change our state of mind.
Dr. Andrew Huberman
Many, many people out there are struggling. They think, my memory is bad. I'm in trouble with focus. But a lot of people have trouble focusing because they're basically spending their focus, if you will, throughout the day.
Dr. Andrew Huberman
The whole idea of social media, you're just, you're context switching, context switching, context switching in a very passive way. And so what I've tried to do is create practices that are grounded in the neurobiology of vision and how vision anchors attention and can induce calm.

2 Protocols
Visual Focus Training for Concentration
Dr. Andrew Huberman- Take a piece of paper and put a small crosshatch on it.
- Place the paper at the distance of your computer.
- Force your vision to that location (vergence eye movement).
- Try to hold your focus, blinking as seldom as possible, for about 60 seconds.
Daily Visual Training for Mental Agility and Transitions
Dr. Andrew Huberman- Close your eyes and concentrate on your internal state (interoception), breathing three times.
- Open your eyes, stare at your hand or something at arm's length, focusing visual attention there, and breathe three times.
- Look into the distance and do the same (focus and breathe three times).
- Shift into panoramic vision (even indoors) and breathe three times.
- Bring your focus back to your internal landscape.
- Optionally, focus on a small crosshatch before getting to work.
