> Analysis of health data from millions of people shows that people on the western edges of time zones get about 19 minutes less sleep every night than people on the east, and also have significantly higher rates of obesity, diabetes and heart attacks than people on the eastern edges. I would love to see this data. If it is really true that people farther west in a time zone have worse health outcomes, and this effect is seen across wide swaths of the world, that is pretty compelling evidence. And I say this as someone who personally would much rather keep DST all year long. It seems like a pattern that would be hard to fake, since it would imply that there is a marked step in health outcomes at every single time zone border. If this pattern really exists in the data, that is really saying something.
