Researchers have spotted some curious links between daylight saving and our health, including [2]fewer heart attacks[/2] when the clocks go back. For others the extra hour in bed this weekend [3]is a time to embrace our inner sloth[/3], the undisputed champion of indolence, and a chance to explore our history of laziness.

They focused on the two weeks before and after the clocks changed. Worryingly, they found a spike in the number of reported heart attacks after the transition to DST in the spring. In contrast, after moving out of daylight savings time in the autumn this trend was reversed. Worryingly when i walk through the forests in spring (around that time) i see a lot of heart-attacked mice which collapsed while crossing sunny forest roads. Note (just in case you never faced this mystery yourself) it must be sunny and warm for that to happen. I always feel sad when i see those corpses, after six to eight months of starvation and piercing cold, died in the first real warmth of spring! Likewise it seems right now many of us (here in Darmstadt) don't want to see the last leaves fall and prefer the everlasting cold instead ((([4]))). Well. The actual data that backs that story above [5] is supported by the "Swedish Council of Working Life and Social Research, Ansgarius Foundation, King Gustaf V and Queen Victoria's Foundation, and the Swedish Heart and Lung Foundation", and it also reads Our data suggest that vulnerable people might benefit from avoiding sudden changes in their biologic rhythms. It has been postulated that people in Western societies are chronically sleep deprived, since the average sleep duration decreased from 9.0 to 7.5 hours during the 20th century.4 Therefore, it is important to examine whether we can achieve beneficial effects with prolonged sleep. The finding that the possibility of additional sleep seems to be protective on the first workday after the autumn shift is intriguing. It follows frightening talk about work on Mondays, so better read it: Not before Tuesday! Have a nice weekend.
