Mar 9, 2023 · The changing of the clock means misalignment with our bodies’ natural rhythms. On Sunday, most of the U.S. will advance their clocks one hour for daylight saving time (DST). The change means disruptions in the sleep patterns of over 300 million people—the effects of which will doubtless be felt and seen nearly everywhere.
Oct 26, 2023 · The end of Daylight Saving Time is typically a trigger for cluster headaches. Cluster headache attacks can occur every day for six to eight weeks and then go away in a cluster cycle. The theory is ...

Setting the clocks forward one hour in spring does not create more daylight, but it does change the time (on the clock) the Sun rises and sets. So, when we spring forwardan hour in spring, we add one hour of natural daylight to our afternoon schedule. 1. Proponents of DST argue that longer evenings motivate people to get out of the house. The extra...
A century ago, when DST was introduced, more daylight was a good thing because it meant less use of artificial light and more energy savings. Modern society, with its computers, TV-screens, and air conditioning units, uses more energy, no matter if the Sun is up or not. Today, the amount of energy saved from DST is negligible. 1. When Indiana decid...
One of the aims of DST is to make sure that people's active hours coincide with daylight hours so that less artificial light is needed. This makes less sense close to the equator, where the amount of daylight does not vary much in a year, or near the poles, where the difference between winter and summer daylight hours is very large. However, at lat...
Changing the time, even if it is only by one hour, disrupts our body clocks or circadian rhythm. For most people, the resulting tiredness is simply an inconvenience. For some, however, the time change can have more serious consequences to their health. 1. Studies link the lack of sleep at the start of DST to car accidents, workplace injuries, suici...
Safety is one of the more solid arguments for keeping the lighter evenings of DST. 1. Studies have found that DST contributes to improved road safety by reducing pedestrian fatalities by 13% during dawn and duskhours. 2. Another study found a 7% decrease in robberiesfollowing the spring shift to DST.
It is hard to determine the economic cost of the collective tiredness caused by DST, but studies have found a decrease in productivityafter the spring transition. 1. The City of New York invested 1.5 million US dollars in a dusk and darkness safety campaignfor the DST change for the fall of 2016. 2. There is an extra cost in building DST support in...

Mar 9, 2024 · Daylight saving time begins Sunday at 2 a.m., an hour of sleep vanishing in most of the U.S. The ritual will reverse on Nov. 3 when clocks “fall back” as daylight saving time ends.
Feb 27, 2024 · Daylight Saving Time (DST) is the yearly practice of setting clocks forward one hour between the months of March and November. The idea behind DST is to conserve – or “save” – natural light, since spring, summer, and early fall days typically get dark later in the evening compared to late fall and winter days.
Jul 23, 2021 · July 26, 2021. Twice a year, many Americans prepare for daylight saving time – a period when time springs forward by an hour in March and falls back in November – by adjusting their clocks. A study in Scientific Reports found this change impacts people differently – based on their tendency to be an early riser or to go to bed later.
