Why You're Exhausted All Day and Wide Awake at Night
Wednesday, 14 October, 2026

Exhausted all day, wide awake at night, and wondering why your brain comes alive at 3 AM? It may be time to take a closer look at cortisol and the everyday demands affecting your stress response. In this episode of The Rebel Nutritionist, I break down what cortisol actually does, why its daily rhythm matters, and why trying to "lower cortisol" doesn't tell the whole story. We explore: • Cortisol's four essential jobs, from helping you wake up to regulating blood sugar and inflammation. • What "tired but wired" feels like and how stress and sleep patterns can interact. • The five "faucets" filling your stress bucket: blood sugar swings, under-fueling and overtraining, inflammation, disrupted sleep and light exposure, and emotional stress. • The often-overlooked weight of people-pleasing, perfectionism, caregiving, and never giving yourself permission to rest. • Possible contributors to those 2–3 AM wake-ups—and why it's important to look beyond cortisol alone. • A simple self-check to help you notice where your biggest demands are coming from. You don't need another reason to be harder on yourself. Understanding what your body is responding to is a place to start. Grab a notebook, rate your five faucets, and bring your list to part two, where we'll explore food, daily rhythms, and mindset in more detail.
