Chronic Fatigue & Burnout

Human trials agree that oral NMN raises NAD+ in the blood. Whether that translates into the longevity benefits the marketing promises is far less settled.

CoQ10 carries electrons through the mitochondrial chain that makes ATP. Why it is studied in chronic fatigue, what trials show, and how status is assessed.

Long COVID and ME/CFS are separate diagnoses with striking biological overlap. What they share, where they differ, and why the distinction changes management.

Circadian disruption may drive the unrefreshing sleep of ME/CFS. How light timing shifts melatonin and fragments sleep, and what helps reset the body clock.

Fatigue that rest doesn’t fix may be ME/CFS or long COVID. How post-exertional malaise and mitochondrial and immune dysfunction are assessed, and what helps.

Feeling tired after a full night’s sleep may come down to sleep perception, not sleep duration. What research on sleep beliefs shows, and where to start.

Author: Rohan Smith | Functional Medicine Practitioner | Adelaide, SA Quick Answer Chronic fatigue is rarely caused by a single problem. Persistent exhaustion may involve disruptions in mitochondrial ATP production, hypothalamic-pituitary-adrenal (HPA) axis cortisol regulation, immune activation (including Epstein-Barr virus reactivation), gut microbiome imbalance, and autonomic nervous system dysregulation. Standard pathology may appear normal because…

Exhaustion that sleep can’t fix often points to the stress response, not sleep. How a flattened cortisol rhythm drains morning energy, and how it is assessed.

A root-cause approach to chronic fatigue weighs thyroid conversion, the HPA axis, gut, mitochondria and post-viral immune activity together, not in isolation.

Still crashing after eight hours of sleep? The problem may be mitochondrial rather than sleep quality. How ATP production falters, and what tends to drive it.
