Metabolic and cellular health linked to chronic fatigue

Research into cellular and metabolic health is providing new insights into the causes of chronic fatigue and burnout. While common solutions often focus on increasing sleep or reducing stress, experts suggest that persistent exhaustion may be linked to how the body processes nutrients and manages metabolism at a cellular level.

Dr. Daniel Sands of Beth Israel Deaconess Medical Center distinguishes between being sleepy and being fatigued, noting that true fatigue can make routine tasks like doing dishes feel exhausting. This type of exhaustion often resists rest and is tied to the efficiency of mitochondria, the structures within cells that convert nutrients like glucose into energy.
