Episode 1: Why You're Still Exhausted After 8 Hours of Sleep
The Root Cause Podcast — brought to you by Mendocino Health and Wellness

Why do some people sleep a full eight hours and still feel completely wiped out? In this first episode, John Corippo and Lauren Strangio dig into the real root causes of fatigue — and it's rarely as simple as "get more sleep." From nutrient deficiencies and emotional/childhood roots to EMFs in your bedroom, adrenal fatigue, blood sugar crashes, and the long-term toll of a nervous system stuck in survival mode, this conversation reframes fatigue as a signal, not just a symptom.

Lauren also opens up about her own experience managing fatigue from Epstein-Barr and Lyme flare-ups despite sleeping well, and John shares a candid look at how 23 years as a first responder rewired his relationship with rest, food, and stress — and what changed once he started paying attention.

In this episode:

• Why fatigue shows up differently for every single person
• The most common assumptions people make about their fatigue (and why they're often wrong)
• Simple sleep environment fixes: EMFs, sleep number beds, and the "bedroom is for sleeping only" rule
• Why fatigue isn't always a sleep problem
• The cortisol connection: why your body gets a second wind after 10pm
• Tracking HRV (heart rate variability) as a window into recovery
• Adrenal fatigue: causes, symptoms, and why stress can become an addiction
• The single biggest sleep mistake people don't want to hear about
• How chronic stress disrupts blood sugar and digestion
• A first responder's perspective on nervous system dysregulation and burnout
• Common food and blood sugar mistakes that quietly drain your energy
• Why "just push through the workout" isn't always the right advice
• Rapid-fire round:
