The importance of sleep regularity: a consensus statement of the National sleep Foundation sleep timing and variability panel

This consensus statement by the National sleep Foundation emphasizes the critical role of regular sleep timing for health, safety, and performance. Irregular sleep patterns, often due to societal pressures like work schedules and artificial light exposure, can lead to misaligned circadian rhythms, increasing risks for health issues such as metabolic disorders, mental health challenges, and reduced performance. The panel also notes that while regular sleep is ideal, compensating for insufficient weekday sleep with weekend rest may still provide some health benefits.

Adopt consistent sleep and wake times, even on weekends, to align with natural circadian rhythms and improve overall health. This recommendation is based on systematic literature reviews and expert consensus, suggesting it applies broadly across populations. Ensure exposure to natural light during the day and minimize artificial light at night for optimal circadian alignment.
