The Stress & Cortisol Cheat Sheet

You need cortisol, adrenaline and stress — training, focus and adaptation all run on it. The real problem is a body that gets the stress signal but never the signal that it's over, and stays half-switched-on for years. So the fix isn't 'just relax'; it's completing the cycle: stress → action → recovery. 90% is the free foundations — sleep, morning light, movement, caffeine, breathing and cutting the doomscroll — and only the last 10% is the cortisol-and-supplement rabbit hole.

It's concrete and honest: the physiological sigh to kill an acute spike, why the morning cortisol peak is normal (not 'stress'), caffeine timing, the evidence on ashwagandha, magnesium and l-theanine — and a 90-second emergency protocol. Plus the one rule: don't eliminate every stressor, become harder to destabilize.
