Visual System

The visual system profoundly influences our brain and body, affecting our state of mind and stress levels. Andrew Huberman explains that when we are stressed, our pupils dilate, and our visual field narrows, creating a "soda straw view" of the world. This change in vision is reciprocal, meaning that by consciously expanding our visual field, we can reduce stress and enhance relaxation 1.

When you are indoors, you're looking at your phone, you're looking at a computer or a camera or something of that sort, or you're talking to somebody, or an intense conversation. You may not notice it, but your entire visual field shrinks to a much smaller aperture and that drives an increase in alertness in internal state.

Additionally, Huberman highlights the physiological sigh, a breathing technique that can rapidly decrease stress by offloading carbon dioxide through a double inhale followed by an extended exhale 2.

   

Vision & Stress

Vision plays a crucial role in managing stress and anxiety by influencing our internal state. Andrew Huberman describes the eyes as extensions of the brain that can alter our alertness and relaxation levels by communicating time of day to our circadian clock 3. This system not only helps us perceive shapes and colors but also dictates our body's readiness for activity or rest.

Our visual system is not just for seeing objects, shapes and colors, et cetera. Our eyes have two functions so much in the same way that our ears are responsible for hearing, but also there's a balance mechanism in there.

Furthermore, both vision and breathing can drive changes in our mental state, offering tools to control stress and gain perspective. By consciously adjusting our visual focus and breathing patterns, we can influence our perception of time and stress, allowing for a more balanced emotional response 4.
