The Utah House’s recent passage of HB120, which proposes a temporary switch to permanent standard time until federal law permits permanent daylight saving time (DST), addresses the widely held desire to eliminate the biannual clock changes. However, the discussion surrounding this legislative move has not fully considered the critical differences and implications of choosing between permanent standard time and permanent DST.
The distinction between these two timekeeping systems is not merely academic nor a choice among equals. It has profound implications for public health and economic stability. Permanent standard time aligns more closely with human circadian rhythms, which are essential for mental and physical health. Morning sunlight is a crucial factor in regulating these rhythms, influencing mood, alertness and metabolic processes. Under permanent DST, Utah could experience sunrises as late as 8:30 a.m. or later during the winter months. Such delays in morning light exposure can lead to increased risks of depression, sleep disorders and other health issues associated with disrupted circadian rhythms.
Moreover, the economic implications should not be overlooked. The ski industry, a significant contributor to Utah’s economy, could face challenges with later sunrises under permanent DST. Essential morning operations like avalanche mitigation and slope preparation would be delayed, potentially reducing the time available for skiing each day. This could impact tourism revenue and employment, highlighting the economic stakes involved in this decision.
The temporary switch proposed by HB120 is a pragmatic step, but it may not fully address the long-term benefits of adopting permanent standard time. The scientific community overwhelmingly supports this approach due to its alignment with natural light-dark cycles, which are vital for health and well-being.
As Utah considers its options, it is crucial to prioritize these scientific insights and the broader implications for both public health and economic vitality. By embracing permanent standard time, Utah can ensure its policies are in harmony with human biology and economic interests, setting a precedent for other states to follow. This informed choice can enhance the well-being of Utah residents while safeguarding key industries that drive the state’s economy.
