In this solo podcast episode, Dr Mike Hart provides actionable, evidence-backed strategies to improve overall circadian rhythm and consequently enhance sleep quality. He discusses the importance of a regulated sleep-wake cycle and its impact on hormone release, metabolism, immune function, and general well-being. Various methods to maintain a healthy circadian rhythm are explored, including the benefits of morning sunlight exposure, the role of blue light blocking in the evening, and the timing of meals and exercise. He also touches on the effects of caffeine and alcohol on sleep, the ideal sleep environment, and additional supportive practices like social interaction, light physical activity, and evening routines that promote relaxation.
