Who this letter is for, what you'll get, and the two posts to read first.
You do everything right and you still can’t switch off.
You’ve read the books. You breathe, you journal, you cold-plunge, you bought the ring. And your body still runs like the stressor never ended: tense at 10pm, wide awake at 3am.
I write this letter for exactly that body.
I’m Lucie, an applied neuroscientist (MSc.) and biofeedback practitioner. In my practice I measure recovery: whether a nervous system actually comes back down after stress, and if it doesn’t, which systems are responsible for that gap in recovery. That gap is what this letter is about.
Every Sunday I send one letter on the science of stress regulation. Each one takes something you feel, the tension that won’t drop, the tired that sleep doesn’t touch, and translates it into what your physiology is actually doing underneath. Big feelings get lighter once you can name the mechanism behind them.
What you’ll find here:
Recovery. Why coming down after stress is the half of the cycle that goes untrained.
The brake. Your nervous system’s active force for coming down. It works like a muscle, and it trains like one.
Patterns. The recovery-failure patterns I see in real assessments, and how to recognize yours.
Self-reading. Learning your own body’s signals, so you know what actually works for you instead of guessing.
If you’re new, read these two first:
I spent months breathing at the wrong pace before I found my resonance frequency
What slow breathing actually does inside your autonomic nervous system
One shoe doesn’t fit all. The recovery that works is the one that fits your body, and finding it is the whole point of this letter.
Measured, not guessed.
