Overview

Narrative review demonstrates how physical exercise disrupts the sleep-obesity cycle in chronic metabolic conditions, highlighting exercise as a circadian synchronizer that improves health.

Key Points

To review the multisystem metabolic, neuroendocrine, and circadian mechanisms through which physical exercise modulates the bidirectional relationship between obesity and sleep disturbances.
Synthesized mechanistic evidence on shared pathophysiology between obesity and sleep impairment, including inflammation, insulin resistance, and autonomic dysfunction.
Evaluated physiological adaptations to exercise, including its role as a non-photic zeitgeber influencing central and peripheral circadian clocks and clock gene expression.
Physical exercise concurrently targets shared dysfunctions by reducing chronic low-grade inflammation, improving autonomic balance, and enhancing metabolic flexibility.
Exercise synchronizes biological clocks as a non-photic zeitgeber, driving clock gene expression and metabolic benefits dependent on time-of-day execution.
Multisystem adaptations from exercise interrupt the reciprocal cycle linking obesity and sleep impairment to attenuate cardiometabolic and psychological risks.
