- Seasonal clock changes align human schedules with natural light patterns at middle latitudes.
- Human circadian rhythms are influenced by sunrise times, especially during winter.
- Sleep-wake cycles tend to synchronize with winter sunrise times.
- The study argues that seasonal DST remains a practical tool for reconciling the conflict between daily schedules and seasonal variation in sunrise times.
- The investigators suggest optimal transition dates for DST as early April and early October.
