18. Reduced Physical Performance
Circadian disruption can lead to decreased muscle strength, slower reaction times, and poorer athletic performance.
Hormonal and metabolic fluctuations caused by irregular sleep-wake cycles interfere with muscle recovery, energy production, and coordination.
Athletes and physically active individuals with misaligned rhythms often report reduced endurance and increased fatigue.
Aligning physical activity with natural circadian peaks can enhance performance, while chronic disruption may hinder both short-term results and long-term fitness progress.
