Cancellation of daylight saving time could have a negative impact on health – study


Canceling daylight saving time could be detrimental to people’s health, according to a peer-reviewed study. The study, by José María Martín-Olalla of the University of Seville, was published in August in International Chronobiology.

Although daylight saving time (DST) – the clock change twice a year – has recently been the subject of much criticism, researchers were unable to fully analyze the potential impact. of the cancellation of the clock change, the study notes.
Martín-Olalla compared the daily rhythms of work and sleep in Germany, where daylight saving time was not observed between 1945 and 1980, and in the United Kingdom, which has observed daylight saving time since. 1918.

He concluded that due to the UK’s long-standing daylight saving time observation, Britons start their daily activities exactly as the sun rises in winter. By comparison, the Germans, who did not observe daylight saving time for 30 years in the 20th century, start their day earlier. He noted that increasing activity in the first winter mornings presents increased risks and is physiologically disadvantageous.

Because they start their day in the dark hours of the winter morning, Germans tend to rely on artificial light and their bodies take time to “catch up,” StudyFinds noted.

Also, if daylight saving time were canceled in the United States, where it has been observed for most of the century, more Americans would start their day earlier in the spring and summer, but that would be unhealthy in the beginning. of winter before sunrise, according to StudyFinds. study as saying.

Just as canceling daylight saving time could distort people’s sleep cycles, maintaining daylight saving time presents its own set of risks to human health. Ideally, people’s daily activities should begin when the sun rises, and daylight saving time is “effective in aligning the start. [of] the working day with the sunrise “and” regulate human activity according to the seasons “in the intermediate latitudes, according to the study.
