Cover of the 19th (and last) edition of the pamphlet "The Waste of Daylight", written by William Willett, who independently conceived DST in 1905. The pamphlet advocated DST for Britain and reported progress toward that goal. (Photo credit: Wikipedia)

One of my favorite books on the topic of sleep is Sleep Thieves by Stanley Coren

One chapter in the book deals with the history of DST (Daylight Saving Time) It also shows convincing data that moving the clocks one hour ahead, increases the risk of car accidents in the mornings by 6% for the first few days following the shift.

In 2008 the NEJM published a piece suggesting there is an increase of heart attacks as a result of DST

Other medical consequences include:

—higher BP

–An increase in appetite

–Fatigue and inattention

However one benefit may actually be an increased number of people exercising in the late afternoon / early evening.

On average it takes 3 to 5 days to reset the biological clock.

In Canada Saskachewan decided not to switch to DST; in the USA, Hawaii, Puerto Rico and the US Virgin Islands also do not switch to DST
