The impact of circadian misalignment on patients with migraine due to clock transitions is not well understood. Our study investigated the immediate effects of standard time (ST) to daylight saving time (DST) transition on sleep and headaches in patients with migraines.

Objectives This study aimed to examine public attitudes toward daylight saving time (DST) and its perceived health consequences in Australia, where state-level variation in DST adoption provides a unique setting to test whether the exposure to DST-related health risk information…

In this study we analyzed average sleep durations across 61 countries to examine the impact of Daylight Saving Time (DST) practices. Key metrics influencing sleep were identified, and statistical correlation analysis was applied to explore relationships among these factors. Count…

Millions of shift workers in the U.S. face an increased risk of depression, cancer, and metabolic disease, yet individual responses to shift work vary widely. We find that a conserved biological system of morning and evening oscillators, which evolved for seasonal timing, may con…

Background: Changes in the daily rhythm can trigger migraine attacks. The sensitivity for triggering attacks is closely linked to the regulation of biological rhythms controlled by the hypothalamus. In over 70 countries around the world, the time is changed between daylight savin…

The potential adoption of permanent Daylight Saving Time in the United States has reinvigorated research examining the impact of circadian misalignment on well-being. We conduct the first study that examines the effect of chronic circadian misalignment on mental health in the Uni…

Summary We explored the effects of daylight saving time clock changes on sleep duration in a large accelerometer dataset. Our sample included UK Biobank participants (n = 11,780; aged 43–78 years) with accelerometer data for one or more days during th…

Poor sleep is becoming increasingly prevalent and is associated with adverse health outcomes. Sunlight exposure may improve sleep by regulating circadian rhythms, increasing vitamin D, and influencing melatonin production. However, research on the sunlight-sleep association is li…

Daylight Saving Time (DST) is the practice of setting the clocks one hour forward from Standard Time (ST) in the spring and back again to ST in the fall. This commentary discusses the impact of bi-annual time changes on sleep and circadian rhythms and suggests avenues to minimize…

The Uniform Time Act of 1966 in the United States requires local clocks to change between standard time (ST) and daylight saving time (DST) in the spring and fall. This biannual clock change is unpopular. According to the 2021 Sleep in America Poll, a nationally representative po…

Academic achievement in the first year of college is critical for setting students on a pathway toward long-term academic and life success, yet little is known about the factors that shape early college academic achievement. Given the important role sleep plays in learning and me…

The present study aimed to determine whether transitions both to and from daylight saving time (DST) led to an increase in the incidence of hospital admissions for major acute cardiovascular events (MACE). To support the analysis, natural visibility graphs (NVGs) were used with d…

Social jet lag refers to circadian misalignment that occurs when people shift their sleep schedules from weekdays to weekends. Social jet lag is linked with numerous negative health outcomes, with emerging research connecting social jet lag to increased consumption of unhealthy f…

In March 2022, the US Senate passed the Sunshine Protection Act that would abolish the biannual change in clocks each fall and spring and permanently adopt daylight saving time that aligns with the “spring forward” time change each March. A number of scientific and medical societ…

Objective To examine the impact of changing school start times on sleep in parents of students in elementary, middle, and high school. Methods Annual surveys were completed by parents of K-12 students (n = 8190-10,592 per year) before (pre-change) and for 2 years (post-change, fo…

Advancing clock times by 1 h in the spring to daylight savings time and setting clock times back 1 h in the autumn to standard time disrupts circadian timing, sleep and skilled motor behavior such as driving an automobile. It is unknown if endurance performance is impacted by day…

BACKGROUND: Daylight Saving Time (DST) annually moves clocks 1 hour forward, when daytime is longer than night. Previous studies from medium and high latitude locations have pointed to a disruptive effect of DST on human circadian rhythms. Since Brazil is an equatorial country im…

Abstract Previous studies indicate that solar clock (daily changes in the Earth’s surface illumination) is a main zeitgeber for human circadian system. It has been shown that human biological clock is weakly adjusted to such changes in social clock as daylight saving time (DST). …

To the Editor: Popular wisdom holds that not getting enough sleep increases the propensity of catching a cold or other ailments. In America, sleep duration has steadily declined from nearly 9 hours in 1960 to less than 7 hours currently. Although adverse effects of sleep deprivat…
