Cortisol is essential — it wakes you up, mobilizes energy, and tunes immunity. The problem is chronically elevated cortisol at the wrong times.
Healthy rhythm
High in the morning (wakes you up), gradually declining through the day, lowest at night. This rhythm depends on light, food timing, and sleep.
What raises it
Under-sleeping, over-training, skipped meals, alcohol, doom-scrolling, and chronic conflict.
What lowers it
Outdoor light, slow nasal breathing, social connection, laughter, prayer/meditation, and consistent meal timing.
