Every year, the debate over permanent daylight saving time returns like the seasons themselves — a reminder that human preference and biological reality do not always align. Scientists studying sleep and circadian health have documented what happens when winter mornings are pushed into prolonged darkness across much of the United States: the body, calibrated over millennia to the sun's position, begins to falter in measurable ways. The choice before policymakers is not simply about clocks, but about which costs a society is willing to absorb — and who bears them most.

Households would face increased accident risks, potential health complications from circadian rhythm disruption, higher insurance premiums, and possible increased energy costs from later morning lighting needs despite evening savings.
Policymakers may face pressure to maintain biannual time changes or adopt permanent standard time instead; potential regulatory responses could include workplace safety standards, school start time adjustments, and public health guidelines to mitigate documented negative effects.
