In this episode of The Science of Ageless Living, Dr. Ethan Hausman-Marquis unpacks autoimmune fatigue in conditions like MS, lupus, and rheumatoid arthritis—and why it’s so often misunderstood. Fatigue isn’t laziness or deconditioning; it’s a biological safety response to chronic inflammation.

He explains how inflammation disrupts neurotransmitters, autonomic balance, and oxidative stress, with mitochondria at the center. In autoimmune disease, mitochondria intentionally downshift energy production to protect cells from damage—an intelligent adaptation, not failure.

A key takeaway: more energy isn’t always better. Aggressive interventions like NAD+ or stimulants can override the body’s protective signals, increasing the risk of flares. True repair happens in parasympathetic, rest-and-digest states.

The episode outlines a smarter strategy built on timing, low-and-slow dosing, and restraint—prioritizing nutrition, sleep, gentle movement, and stress regulation before metabolic “boosts.” Fatigue is reframed as a signal to respect biology, not fight it.
