Fatigue is one of the most common and debilitating aspects of depression. Understanding its causes enables better management.
Why Depression Causes Fatigue
- Neurological: The constant vigilance of depression is neurologically expensive
- Sleep disruption: Even subtle depression-related sleep interference causes significant fatigue
- HPA axis dysregulation: Chronic stress hormones deplete physical energy
- Inflammation: Elevated inflammatory markers in depression cause fatigue directly
- Emotional labor: Processing depression throughout the day is exhausting
Fatigue vs. Laziness in Depression
Depression fatigue is physiological, not motivational. Pushing through it without addressing depression makes both worse.
Managing Depression Fatigue
- Prioritize sleep: First-line intervention
- Pacing: Strategic energy management — activity balanced with recovery
- Treat depression directly: Addressing depression typically improves fatigue
- Light exercise: Counter-intuitively, gentle movement often reduces depression fatigue
