Using a real community question as the foundation, she explains why feeling “wired but tired” isn’t a personal failing, but a physiological response to chronic, unresolved stress. Mikki walks through how cortisol actually works, why both exercise and life stress use the same biological pathways, and what happens when your system never fully downregulates. She also explores the role of the HPA axis, autonomic nervous system imbalance, and why tools like HRV and resting heart rate can offer insight—but also create more stress if misused. Most importantly, this episode delivers practical, evidence-based strategies to help restore balance and build resilience. Key Highlights: Why cortisol is not the villain—and what it actually does The difference between acute stress and chronic, unresolved stress What a high morning heart rate is really telling you How lifestyle, hydration, and training load impact your stress response Practical tools to downregulate your nervous system Contact Mikki: https://mikkiwilliden.com/ https://www.facebook.com/mikkiwillidennutrition https://www.instagram.com/mikkiwilliden/ https://linktr.ee/mikkiwilliden NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nz Save 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz , www.nuzest.com.au or www.nuzest.com Curranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/mikkipedia-1319728/episodes/mini-mikkipedia-cortisol-stress-why-you-feel-wired-and-tired/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/mikkipedia-1319728/mini-mikkipedia-cortisol-stress-why-you-feel-wired-and-tired.md` — Read the agent-friendly Markdown representation of this episode resource.
