There is evidence that the spring Daylight Saving Time (DST) transition acutely increases motor vehicle accident (MVA) risk ("DST effect"), which has been partly attributed to sleep deprivation and circadian misalignment [1-6]. Because spring DST also shifts clock time 1 h later, mornings are darker and evenings brighter, changing illumination conditions for peak traffic density. This daytime-dependent illumination change ("time of day effect") is hypothesized to result in DST-associated… Expand
Daylight saving time: an American Academy of Sleep Medicine position statement.
It is 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. Expand
Effect of Daylight Saving Time clock shifts on white-tailed deer-vehicle collision rates.
DST clock-shift results in an increase in the number of white-tailed deer-vehicle collisions, and therefore injuries and property damage associated with such accidents in New York State, it is concluded. Expand

The increase in daily mortality as observed in the week after spring DST-transition is most likely causally linked to the change in time scheme. Expand
A chronobiological evaluation of the risks of canceling daylight saving time.
The long-term impact of seasonal regulation of clocks (Daylight Saving Time) is analyzed showing that it helped to mitigate the advance of the phase of human activity during the twentieth century andExpand
The Welfare Effects of Time Reallocation: Evidence from Daylight Saving Time
Daylight Saving Time (DST) is currently implemented by more than seventy countries, yet we do not have a clear knowledge of how it affects individuals’ welfare. Using a regression discontinuityExpand
Traffic accident increase attributed to Daylight Saving Time doubled after Energy Policy Act
Martín-Olalla argues that an important factor in the association between motor vehicle fatalities and the switch to Daylight Saving Time is the timing of the switch, which in the US changed with theExpand
Response to Martín-Olalla
Vetter et al. respond to Martín-Olalla's comment about their study linking motor vehicle fatalities to the transition to Daylight Saving Time.

The impact of daylight saving time on sleep and related behaviours.

Indirect evidence of an increase in traffic accident rates, and change in health and regulatory behaviours which may be related to sleep disruption suggest that adjustment to daylight saving time is neither immediate nor without consequence. Expand
Fatal accidents following changes in daylight savings time: the American experience.
The sleep deprivation on the Monday following shift to DST in the spring results in a small increase in fatal accidents, suggesting an increase in late night driving when traffic related fatalities are high possibly related to alcohol consumption and driving while sleepy. Expand
The Human Circadian Clock's Seasonal Adjustment Is Disrupted by Daylight Saving Time
The data indicate that the human circadian system does not adjust to DST and that its seasonal adaptation to the changing photoperiods is disrupted by the introduction of summer time, which may extend to other aspects of seasonal biology in humans. Expand
The Effects of Daylight Saving Time on Vehicle Crashes in Minnesota
The path analysis shows that overall DST reduces crashes, and while DST per se is associated with fewer crashes during dusk, this is in part offset because it is also associated with more traffic on roads (and hence more crashes). Expand
Sunset time and the economic effects of social jetlag: evidence from US time zone borders.
This study uses a spatial regression discontinuity design to estimate the economic cost of the misalignment between social and biological rhythms arising at the border of a time-zone in the presence of relatively rigid social schedules. Expand
Impact of daylight saving time on road traffic collision risk: a systematic review
The evidence cannot support or refute the assertion that a permanent shift in light from morning to evening will have a road safety benefit, as a range of road collision risk factors vary over time. Expand

To the Editor: It has become increasingly clear that insufficient sleep and disrupted circadian rhythms are a major public health problem. For instance, in 1988 the cost of sleep-related accidentsExpand
Longitude Position in a Time Zone and Cancer Risk in the United States
Risk increased from the east to the west in a time zone for total and many specific cancers, in accord with the circadian disruption hypothesis, suggesting that circadian disruption may not be a rare phenomenon affecting only shift workers, but is widespread in the general population with broader implications for public health than generally appreciated.

Daylight saving time and motor vehicle crashes: the reduction in pedestrian and vehicle occupant fatalities.
Fatal crashes were tabulated for 6-hour periods around sunrise and sunset, from 13 weeks before the fall change to standard time until 9 weeks after the spring change to daylight saving time.Expand
Why Should We Abolish Daylight Saving Time?
The authors take the position that, based on comparisons of large populations living in DST or ST or on western versus eastern edges of time zones, the advantages of permanent ST outweigh switching to DST annually or permanently. Expand
