The circadian rhythm plays a vital role in health by regulating the sleep-wake cycle, impacting various physiological processes. Disruptions to this rhythm, often due to irregular sleep patterns, can lead to issues such as insomnia, fatigue, and reduced cognitive function. Furthermore, a well-aligned circadian rhythm supports hormonal balance, appetite regulation, and metabolic health. Consistency in sleep schedules and exposure to natural light helps maintain this rhythm, optimizing overall health and wellness. Thus, adhering to natural biological clocks can significantly improve both physical and mental health outcomes.
