Falling back

Scientists have examined DST’s impacts on human health, and the conclusions have been mixed.

The article continues:

Two studies, conducted in the United States and Sweden, found that heart attack risk increased by up to 25 percent on the Monday after we move the clocks ahead. The same researchers found that the risk dropped by 21 percent when the clocks fall back.

Till Roenneberg, a chronobiologist at Ludwig-Maximilians University in Munich, argues that our bodies’ circadian clocks never entirely adjust to the shift in daylight hours. So while more morning light helps jump-start our bodies, the extra evening light leads to a lag.

“The consequence of that is that the majority of the population has drastically decreased productivity, decreased quality of life, increasing susceptibility to illness, and is just plain tired,” Roenneberg previously told National Geographic.
