For the past 7 years, Sleeptracker-AI® studies of millions of nights of sleep data consistently show a marked disruption in sleep patterns each fall when clocks are set back and we lose an hour of daylight. In contrast, Arizona—where time remains unchanged year-round—shows no such disturbance.

Isn’t it time to end this outdated ritual? In today’s modern world, maintaining consistent time would help preserve healthy sleep cycles and give busy people a precious extra hour of daylight to enjoy fresh air and sunlight after work.
