Science:
Cortisol isn’t the problem — chronic elevation is. Persistent stress keeps your brain in “threat mode”, impairing recovery and focus.
Action:
Do a 5 minute physiological sigh (double inhale + long exhale) during your highest stress moment today.
From the Neurologist:
Chronic cortisol damages the hippocampus and impairs memory, focus, and emotional regulation.
