What Causes Chronic Fatigue?
Persistent fatigue that doesn't improve with rest often points to an underlying imbalance — from nutrient gaps to sleep quality to thyroid function.
🩸 Iron or B12 Deficiency
The most common nutritional cause of persistent fatigue, especially in women and vegetarians.
🦋 Thyroid Imbalance
An underactive thyroid slows metabolism, often causing fatigue, cold intolerance, and weight changes together.
😴 Poor Sleep Quality
Even with 8 hours in bed, fragmented or shallow sleep fails to restore energy.
😰 Chronic Stress / Adrenal Fatigue
Sustained high cortisol followed by burnout leaves the body running on empty.
