Standard time matches our body’s internal clock. The daily cycle of natural light and darkness is the most powerful timing cue to synchronize our body’s internal clock. When we receive more light in the morning and darkness in the evening, our bodies and nature are better aligned, making it easier to wake up for our daily activities and easier to fall asleep at night. Daylight saving time disrupts our internal clock, leading to sleep loss and poor sleep quality, which in turn lead to negative health consequences.
