A study, published in 2007 in the journal BMC Biology, combined surveys from 55,000 people in central Europe with data on 50 individuals' sleeping and wakefulness patterns for eight weeks around the shifts to and from daylight saving time. The researchers found people never fully adjust their circadian rhythms to the hour shift associated with daylight saving time (or, as it is known in Europe, summer time).
So what effects does the transition have? A cursory search indicates the evidence so far is mixed. <snip>
There is also evidence that heart attacks increase the first three weekdays after the transition to daylight saving in spring.
"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther
The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
