A leading sleep researcher is sounding the alarm about the potential dangers of making daylight saving time permanent across the United States. Dr. Wendy Troxel, a prominent sleep medicine expert, cautions that scientific evidence does not support this policy shift and warns of serious consequences for millions of Americans. Rather than improving our lives as proponents suggest, permanent daylight saving time could actually disrupt the natural sleep-wake cycles that our bodies depend on for optimal health.
The primary concern centers on how this change would affect our circadian rhythms—the internal biological clock that regulates sleep, hormone production, and countless other vital functions. By keeping clocks permanently set forward, millions of people would experience misalignment between their body’s natural rhythm and their daily schedule, making it harder to fall asleep and maintain quality rest. This disruption extends far beyond simple tiredness.
The ripple effects could be profound and widespread. Poor sleep quality is linked to increased rates of depression, anxiety, and other mental health issues. Additionally, sleep deprivation impairs cognitive function and reaction time, potentially compromising public safety on roads and in workplaces. Dr. Troxel’s message is clear: before implementing permanent daylight saving time on a national scale, policymakers should carefully consider the robust scientific evidence showing its negative impact on population health and wellbeing.
