Exercise modulates circadian rhythm regulation and may improve neurological outcomes in stroke and Alzheimer's disease
This review synthesizes evidence that exercise acts as a non-photic zeitgeber, regulating core clock gene expression, synchronizing hormonal and metabolic rhythms, and reducing neuroinflammation. These mechanisms enhance circadian amplitude, stability, and phase alignment, potentially promoting physiological resilience and reducing disease vulnerability. In stroke and Alzheimer's disease, appropriately timed exercise may improve neurological outcomes through neuroplasticity, immune regulation, and metabolic synchronization.

Frequently Asked Questions
How does exercise affect circadian rhythms?▼
Exercise acts as a non-photic zeitgeber, regulating core clock gene expression, synchronizing hormonal and metabolic rhythms, and reducing neuroinflammation, which enhances circadian amplitude, stability, and phase alignment.
Can exercise help in neurological diseases like stroke and Alzheimer's?▼
Yes, by restoring circadian alignment, appropriately timed exercise may improve neurological outcomes through effects on neuroplasticity, immune regulation, and metabolic synchronization, potentially reducing disease vulnerability.
What is the best time to exercise for circadian benefits?▼
The abstract does not specify a particular time, but it emphasizes 'appropriately timed exercise' as important for circadian alignment.
Is exercise a proven treatment for circadian disruption in neurological diseases?▼
Current evidence suggests it is a promising non-pharmacological strategy, but more research is needed to establish definitive clinical recommendations.
