A Quick-Start Guide to Stress Physiology
Stress isn't just a feeling — it's a measurable physiological state. Here's a practical starting point for recognizing dysregulation and rebuilding baseline regulation.
Stress comes up in nearly every intake I do, usually as a contributing factor to something else — sleep, digestion, fatigue, mood, even blood sugar. It's rarely the whole explanation, but it's almost never irrelevant either, and most people have never had it explained to them as a physiological state rather than just a feeling.
Stress is a body state, not just a mood
When your nervous system perceives a demand — physical, emotional, or otherwise — it shifts into a more activated state: heart rate and blood pressure rise, digestion slows, blood sugar mobilizes for quick energy, and attention narrows. That response is useful in short bursts and genuinely costly when it runs for weeks or months without enough recovery in between.
The problem for most people isn't that this response exists. It's that modern stress is chronic and low-grade rather than acute and resolved, so the body never fully downshifts out of it.
Recognizing dysregulation
A few signs that stress physiology has become the baseline rather than an occasional state:
- Feeling "tired but wired" — exhausted, but unable to fully relax or sleep
- Digestive symptoms that flare specifically during stretches of high stress
- A short fuse or emotional reactivity that feels disproportionate to what's actually happening
- Getting sick more easily, or slower to recover when you do
None of these are diagnoses on their own, but together they're a pattern worth naming rather than pushing through indefinitely.
Where to start
Rebuilding regulation is less about eliminating stress — often not realistic — and more about giving your nervous system real recovery between demands: consistent sleep, regular movement, and deliberate downshifting practices that you actually do rather than ones that sound good. What works varies by person, which is why a generic list rarely sticks.
I've put together a fuller written guide with more practical detail. If stress is a significant piece of what's going on for you, it's also a reasonable thing to bring up directly on an intro call.
