Public opinion polls have shown strong support for ending daylight saving time. In a survey of a nationally representative sample of 1,500 U.S. adult citizens, 63% of U.S. adult citizens favored abolishing daylight saving time, 21% were unsure, and 16% opposed abolishing daylight saving time. Time change . Nearly twice as many Americans preferred daylight saving time to daylight saving time. Senior citizens (over 65 years old) were more supportive of ending the time change than their younger counterparts. In a separate survey, 75% of American adults wanted to end daylight saving time, 43% preferred permanent ST, and 32% preferred permanent daylight saving time; This survey also showed that older adults preferred to end the time change compared to younger adults. Loss of sleep and decreased well-being are two factors that have been identified as being affected by the time change.-----

1) Loss of sleep. Studies of time use data (which capture how individuals spend their time) have documented that individuals sleep, on average, 15 to 20 minutes less per night in the week following the spring transition to daylight saving time .-----

2) Wellbeing. Lower sleep quality was reported up to 2 weeks after the spring transition, with easier adjustments in the fall transition back to ST. An American Academy of Sleep Medicine survey of more than 2,000 adults in the U.S. found that more than half of Americans (55%) generally feel tired after the transition from spring to daylight saving time. -----

3) Cerebrovascular accidents. Stroke hospitalizations increased significantly during the first 2 days after the spring and fall transitions, with a relative risk of 1.08. Women, older adults, and people with cancer had a higher susceptibility.----

4) Myocardial infarction. A meta-analysis of more than 115,000 patients documented an increased risk of acute myocardial infarction during the transition from spring to daylight saving time. Atrial fibrillation was also found to increase in the four days following the spring daylight saving time transition.------

Circadian misalignment can alter gene expression, increase the production of inflammatory markers, and reduce vagal tone, resulting in increased heart rate and blood pressure. ----

5) Traffic accidents. The largest study to date, of more than 700,000 car accidents, found that the risk of fatal traffic accidents increases modestly during the transition from daylight saving time to spring, especially in the morning and in places further west in an area time .----

6) Comparative analysis. The link covers the arguments for adopting permanent ST and the arguments in favor of permanent daylight saving time, comparing the differences.------
