“…Studies have demonstrated that DST could have an effect on physical or mental diseases and accidents characterised by seasonal, temporal or circadian rhythmicity and particularly sensitive to disturbances of the sleep-wake cycle 7,8 . Spring transitions were found to be associated with a shift in onset as well as a modestly increased risk of myocardial infarction (MI) 7,[9][10][11][12][13][14][15][16] , ischaemic stroke (IS) 17,18 , motor vehicle accidents (MVAs) [19][20][21] , atrial fibrillation (AF) 22 , patient safetyrelated incidents (SRIs) 23 and suicides 24,25 . Because these conditions represent a high proportion of general mortality, it was hypothesised that DST could impinge on general mortality patterns 26 .…”

Daylight saving time (DST) consists in a one-hour advancement of legal time in spring offset by a backward transition of the same magnitude in fall. It creates a minimal circadian misalignment that could disrupt sleep and homoeostasis in susceptible individuals and lead to an increased incidence of pathologies and accidents during the weeks immediately following both transitions. How this shift affects mortality dynamics on a large population scale remains, however, unknown. This study examines the impact of DST on all-cause mortality in 16 European countries for the period 1998-2012. It shows that mortality decreases in spring and increases in fall during the first two weeks following each DST transition. Moreover, the alignment of time data around DST transition dates revealed a septadian mortality pattern (lowest on Sundays, highest on Mondays) that persists all-year round, irrespective of seasonal variations, in men and women aged above 40.

“…Effect of DST to cardiovascular deaths is unclear ( Manfredini et al, 2019 ). Number of hospital admissions due to atrial fibrillation has been also associated to DST in the spring time especially in female patients ( Chudow et al, 2020 ). DST has shown also increased incidence of ischemic strokes ( Malow, Veatch & Bagai, 2020 ; Sipilä et al, 2016 ).…”

Background Daylight Savings Time (DST) transition is known to cause sleep disruption, and thus may increase the incidence of injuries and accidents during the week following the transition. The aim of this study was to assess the incidence of femur fractures after DST transition. Methods We conducted retrospective population-based register study. All Finnish patients 70 years or older who were admitted to hospital due to femur fracture between 1997 and 2020 were gathered from the Finnish National Hospital Discharge Register. Negative binomial regression with 95% confidence intervals (CI) was used to evaluate the incidence of femur fractures after DST transition. Results The data included a total of 112,658 femur fractures during the study period between 1997 and 2020, with an annual mean (SD) of 4,694 (206) fractures. The incidence of femur fractures decreased at the beginning of the study period from 968 to 688 per 100,000 person-years between 1997 and 2007. The weekly mean of femur fractures remained lower during the summer (from 130 to 150 per 100,000 person-weeks) than in winter (from 160 to 180 per 100,000 person-weeks). Incidence rate ratio for the Monday following DST transition was 1.10 (CI [0.98–1.24]) in spring and 1.10 (CI [0.97–1.24]) in fall, and for the whole week 1.07 (CI [1.01–1.14]) in spring and 0.97 (CI [0.83–1.13]) in fall. Conclusion We found weak evidence that the incidence of femur fractures increases after DST transition in the spring.

“…Shifting from standard time to DST has been associated with increased cardiovascular morbidity, including risk of myocardial infarction, 7,8 stroke, 9 and hospital admissions due to the occurrence of acute atrial fibrillation. 10 An increase in missed medical appointments and increased emergency room visits and return visits to the hospital are also seen only during the spring transition from standard time to DST. 11,12 The one-hour time shift in the spring results in less exposure to light in the morning and greater exposure to evening light.…”

The last several years have seen intense debate about the issue of transitioning between standard and daylight saving time. In the United States, the annual advance to daylight saving time in spring, and fall back to standard time in autumn, is required by law (although some exceptions are allowed under the statute). An abundance of accumulated evidence indicates that the acute transition from standard time to daylight saving time incurs significant public health and safety risks, including increased risk of adverse cardiovascular events, mood disorders, and motor vehicle crashes. Although chronic effects of remaining in daylight saving time year-round have not been well studied, daylight saving time is less aligned with human circadian biology-which, due to the impacts of the delayed natural light/dark cycle on human activity, could result in circadian misalignment, which has been associated in some studies with increased cardiovascular disease risk, metabolic syndrome and other health risks. It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time.
