Can’t Fall or Stay Asleep? Your Sleep Questions Answered

Sleep is one of the most important and most overlooked drivers of your health. If you’re struggling to fall asleep, waking up at 2–4am, or getting a full night’s sleep but still feeling exhausted, your body is trying to tell you something. Poor sleep isn’t just about habits, it’s a signal that key systems like your nervous system, blood sugar, hormones, or circadian rhythm are out of sync. In this episode, we break down what’s actually disrupting your sleep and how to fix it at the root. Here’s what you’ll understand: • Why sleep issues are rarely just one problem and how stress, blood sugar, and circadian rhythm all interact • The real reasons you can’t fall asleep, wake up in the middle of the night, or feel tired despite 7–8 hours • What actually helps (and what doesn’t)—from magnesium and melatonin to nervous system regulation • The 5 core pillars of better sleep and the highest-impact changes you can start tonight Sleep isn’t something you force, it’s something that happens when your body feels safe, balanced, and supported. When you address the root causes, better sleep becomes not just possible but predictable. Visit ⁠functionhealth.com for 160+ lab tests at just $365 a year.
