Disrupting Your Muscle’s Internal Clock Can Lead to Muscle Loss - AI Podcast

Story at-a-glance

Skeletal muscles have their own circadian clocks that regulate daily cycles of growth, repair, energy production, and protein turnover
A recent study found that disabling these peripheral clocks in the muscles caused premature aging, reduced strength, slower movement, and other signs consistent with sarcopenia
These findings help explain why shift workers often experience early muscle decline, as disrupted rhythms interfere with the body’s natural overnight repair processes
Light is the most powerful timing cue for your internal clocks, with morning sunlight helping anchor circadian rhythms and exposure to blue light at night disrupting melatonin and recovery
Meal timing and consistent sleep schedules also help reinforce muscle clock function and support long-term strength and resilience
