Somewhere along the line, we seem to have collectively forgotten what a calm nervous system actually feels like.
People wake exhausted, flood themselves with caffeine, race through the day fuelled by stimulants, sugar and stress hormones, then lie awake at night wondering why they feel anxious, restless or unable to settle. And because humans are meaning-making creatures, we rarely experience physiological activation as physiology. We interpret it psychologically.
“I’m overwhelmed.”
“I can’t cope.”
“Something bad is going to happen.”
“My anxiety is terrible.”
Now, of course anxiety is real. Human beings suffer. Life is hard. But I increasingly wonder how many people are unknowingly living inside chronically stimulated nervous systems and then building entire identities and narratives around the sensations that follow.
Because stimulants don’t just affect the mind. They affect the body. The bowel included.
Anyone working in gut health sees this constantly. Coffee can stimulate bowel motility. Energy drinks can create urgency, cramping, loose stools, reflux, bloating, jitters, sweating and that strange internal sense of “being driven.” Some people become constipated under stress; others practically develop a direct espresso-to-toilet transit system.
The bowel is not separate from the nervous system. It is exquisitely responsive to it.
And yet modern culture treats permanent activation as normal.
Teenagers and young adults consume enormous amounts of caffeine through coffees, pre-workouts, fizzy drinks and energy drinks while simultaneously sleeping badly, scrolling endlessly, living indoors, moving less, worrying more and existing under relentless cognitive stimulation. Then we act surprised that anxiety disorders are soaring.
To be clear, caffeine itself is not evil. Used consciously, caffeinated drinks can sharpen thinking beautifully. I occasionally use them myself (Synergy’s E9) and can feel the almost crystalline clarity they create. For some nervous systems, especially more chaotic or scattered ones, stimulation can even create a paradoxical sense of order.
But there is a difference between feeling alive and being activated.
That distinction matters.
A regulated nervous system can usually tolerate stimulation and then return to baseline. An already dysregulated nervous system often cannot. The stimulation doesn’t create the fire from nowhere; it pours accelerant onto embers already burning beneath the surface.
And perhaps this is the deeper issue: many people no longer recognise the sensation of regulation. Calm feels flat. Stillness feels unfamiliar. Silence feels uncomfortable. So they oscillate endlessly between stimulation and collapse, mistaking activation for vitality.
Sometimes the body is not telling a psychological story at all.
Sometimes it is simply saying:
“Too much; too long” xx
