Hyper-Stimulated World

Hyper-Stimulated World

As the cool water envelopes my feet I sense my continuity with the water, indeed with all of life. I am home exactly where I am. This was a thought I had yesterday while out rock climbing on the river near where I live. This was not some kind of mind-blowing spiritual revelation. Just a simple moment of uncomplicated awareness. What did strike me on reflection though was how much this is related to why I am doing the Slow Project and Way of Nature retreat guiding. While I consider such moments at once profound yet also ordinary, I remember that this was not always the case and truly appreciate the effect this quality of awareness has had on my life. Let’s take a step back and have a look at our senses in today’s world. Most of human history has been spent in times where there were immediate physical dangers. Our nervous systems have adapted accordingly. We are hardwired to react to novel stimuli because, as far as our nervous system knows, it might indicate a threat. These days most people do not live in situations where danger might lurk around every corner, however the quantity and intensity of sensory input has escalated off the charts. Consider the changes to the human habitat since the industrial revolution; increasing density of urban living, cars, advertisements, marketing materials, loud speakers, artificial light, etc. It is a ‘hyperstimulated’ world that we live in. You might be wondering what is the problem with this stimulation. We do have positive association with the word ‘stimulated’ and I agree that intense sensory input cannot be glorious in itself, but everything is about balance. “Silence is the sleep that nourishes wisdom” – Francis Bacon Some people are particularly prone to adverse reactions to excessive stimulation. I became interested in sensory processing during my time as as an Occupational Therapist. I learnt about how our nervous systems must filter through and modulate incoming stimuli in order for us to be able to function. Efficient sensory modulation is the ability to effectively regulate the degree to which one is influenced by various sensory inputs. For many people, and especially children as their nervous system is still maturing, sensory processing poses a challenge and disorders result. We all have different ‘sensory profiles’, sensing and letting in different quantities of stimuli from our various sense organs and then filtering it differently through our systems of perception. Even if it is not at a ‘disorder’ level, we have our own sensory challenges. I also wonder if the changing sensory environment of the modern world is leading to an increase in sensory processing disorders because it is not what our nervous systems evolved to live in. Too much sensory stimulation results in a stress response and sometimes a ‘shut down.’ Sensory overload has actually been used as a method of torture. Bit of a side note – but it was too interesting not to mention – in my research I discovered that creative people tend to have reduced ‘sensory gating’; letting in more stimuli than others. However when our prefrontal cortex is activated, creativity is suppressed. The prefrontal cortex has a novelty bias, cranking itself up for new stimuli and moving your attention to the source of the stimuli.((http://www.theguardian.com/science/2015/jan/18/modern-world-bad-for-brain-daniel-j-levitin-organized-mind-information-overload)) Creatives often advocate for the need for silence. This bombardment and relentless activation of the prefrontal cortex also fractures our attention, switching our focus over to the source of the new stimuli. This is a disaster for efficiency and also delivers a double stress-whammy. Multitasking increases the production of the stress hormone...
