(SCIENTIFIC AMERICAN) It’s nearly that time of the year again: the end of daylight saving, when Americans push their clocks back and rejoice at the gained hour of sleep—or mourn the lost hour of sunlight in the afternoon.
This system’s twice-a-year transitions have become increasingly unpopular. Scientists have been calling attention to the damaging effects of the time changes—which include a general reduction in mental and physical well-being, as well as a potential increased risk of serious complications, such as strokes and heart attacks, soon after the shifts. There is also evidence of increases in traffic fatalities and harmful medical errors shortly following when clocks are moved forward in the spring.
In many countries, this might be the one of the last instances in which people make the adjustment.
