PRESS RELEASE – Europe & North America – October 21, 2020 – For Immediate Use
European and North American NGOs and advocates for healthy time-use have joined to form the International Alliance for Natural Time. Backed by renowned scientists and experts in the fields of chronobiology, neuroscience, economic science, and social science, the Alliance emphasizes natural time for health, safety, education, economy, and environment. They urge governments on both continents to restore permanent, sun-based time zones as soon as possible, preferably before March of 2021.
Wrongly set clocks regularly force too much of the population to wake before sunrise, leading to structural sleep deprivation and disruption to biological clocks. The circadian system directs all bodily processes, and it takes cue from local sunlight — not by clocks on phones. To ignore this reality affects quality of sleep, mental and physical health, performance at work, school, and on the road, and economy at large. …
Both changing to Daylight Saving Time (DST) and remaining on DST have high economic costs, which manifest as stock-market disruption, lost productivity, workplace injuries, healthcare expenses, and overall lower earnings.[CBC][Daily Hive][Jin & Ziebarth][Kalidindi][Watson]
Workplace injuries in US laborers increase 5.7% in the days after moving clocks forward to DST in spring, due to the sudden loss of an average of 40 minutes of sleep. Injuries increase in severity too, resulting in 67.6% more days lost after moving clocks forward.[Barnes & Wagner] US office productivity drops 20% upon the springtime clock change to DST, for a loss of $434M annually nationwide.[Wagner][Wagner & Barnes] Stocks drop 200 to 500% more than usual the Monday after moving clocks forward to DST, at a cost of $31B in the US.[Roenneberg 2019–08] These injuries, missed days, lost productivity, and stock losses don’t reoccur in the autumn return to Standard Time, nor are they ever recouped.[Barnes …

Re: Please amend endorsement from DST to Standard Time, for health, children, and climate.
Thank you for continuing to move humanity forward after the close of your groundbreaking presidential campaign. Even before your first debate appearance, I personally lauded your prioritization of science in politics. …
Experts in the research of circadian health warn permanent Daylight Saving Time (DST) “undermines”[Cell Press] and “negates”[Skeldon & Dijk] the necessary and popular benefits of starting school later, and that lawmakers who support both Start School Later and permanent DST are “confused”.[Nedelman][Skeldon & Dijk]
Proponents of permanent DST claim civil clocks are arbitrary. Meanwhile, data and history show “every cell”[Cytowic][Reddy] in our bodies is “entrained”[Gu][Kantermann][Roenneberg 2019–08][Thomas] to solar time, and that we “never adjust”[Curtis][Holliday][Kalidindi][Kantermann][Livingston 2016][Watson] to DST, even when DST is made permanent. …
The springtime change to DST shocks the human circadian system with a sudden loss of 40 minutes of sleep on average.[Barnes & Wagner] This disruption negatively affects reaction times,[Medina] which causes traffic deaths in the US to spike 17% the Monday after changing to DST.[Boynton] The increase in road deaths persists at a rate of 5.6%[Smith] to 6%[Fritz] the remaining week after changing. A minimum average of 28 lives per year are lost due to “springing forward”.[Fritz] …
Both the change of clocks to Daylight Saving Time (DST) and the continual observation of DST pose lethal threats to human health. Changing clocks causes acute harms that persist for several days or even several weeks.[Berk][Giuntella & Mazzonna][Roenneberg 2019–08][Smith] Continually observing DST causes chronic harms that last for months (in the case of seasonal observance) or years without end (in the case of year-round observance). We “never adjust”[Curtis][Holliday][Kalidindi][Kantermann][Livingston 2016][Watson] to DST — instead we sleep less long and less well than we need.
The abrupt move forward in springtime by one hour is well-known for its shock to body and mind — causing traffic deaths, workplace accidents, lost productivity, and hospitalizations. Incidence of stroke spikes by 9%[Watson] after changing clocks to DST in spring. Incidence of heart attack increases by a range of 24%[Brueck][Michigan][Sandhu] up to 50%[Peralta] the Monday after changing to DST, and this increase continues at a range of 5%[Livingston 2016] up to 15%[Livingston 2020][Reddy] in the week that follows. Even more notably, heart attack rates decrease by a range of 10%[Livingston] to 21%[Brueck][Michigan][Sandhu] after returning clocks to Standard Time in autumn. …
A handful of politicians seek to extend Daylight Saving Time (DST) to the full year. Biannual clock-switching is harmful, but year-round DST is worse, even deadly.
Year-round Standard Time instead would save lives, improve physical and mental health, reduce pollution, slow global warming, save money, and prove more popular. It’s for good reason that year-round DST has long been discouraged by law. Legislate by data, not anecdote.
Both the change of clocks to DST and the continual observation of DST are lethal to human health.
The abrupt move forward in springtime by one hour is well-known for its shock to body and mind — causing traffic deaths, workplace accidents, lost productivity, and hospitalizations. Incidence of stroke increases 9% upon switching to DST in spring. Incidence of heart attack increases 24 to 50% after switching to DST, and it decreases 21% after returning to Standard Time in autumn. These acute effects persist for four days after switching clocks forward. …
