You'll also have more car accidents, heart attacks, sleep deprivation, etc. People, especially adolescents, should be able to sleep in more and given societies current 9-5 scheduling, the sooner the sun goes down (by the clock) the more sleep that people generally get.

Anecdotally: in places like Michigan where it's dark by 6pm in the winters, darkness really has no correlation with sleeping hours. "2-DST" would actually make it easier for working people to align their sleep schedule with the daylight.

  "2-DST" would make it so that people have to get up much earlier in the day though, right? From my experience, in places up north people find it harder to wake up early in the winter because the morning darkness (I'm sure the cold doesn't help either).

    At high latitudes, it doesn't get light until so late that you will reasonably never wake up in daylight in the winter. But moving the light later would make it more likely that you can get out and actually see some light as opposed to going to work when it's dark and getting out when it's dark again.

      It's not about waking up in daylight. It's about a large chuck of the population waking up earlier than is healthy. When you have research showing that the western edge of a timezone is worse off health- and sleep-wise, it is clear that a policy pushing people to get up earlier is not good.

Additionally, the OP seems to indicate the increased accidents are due to issues we have adjusting to the time change. You can certainly argue we should get rid of the time change altogether, but 2-DST would have the same time changes as our current system. Maybe there's an increased risk of traffic accidents as a result of increased evening activity. But I'd argue that's a problem with our society's unhealthy dependence on cars, rather than with 2-DST.

  While the article is specifically looking at the effects of the transition to DST, it references the fact that there are adverse effects of time zones besides just the transition or the use of cars. Here is one of their references: https://www.researchgate.net/profile/Mikhail_Borisenkov/publication/49752430_Latitude_of_Residence_and_Position_in_Time_Zone_are_Predictors_of_Cancer_Incidence_Cancer_Mortality_and_Life_Expectancy_at_Birth/links/0912f503c9f6283dc3000000/Latitude-of-Residence-and-Position-in-Time-Zone-are-Predictors-of-Cancer-Incidence-Cancer-Mortality-and-Life-Expectancy-at-Birth.pdf https://www.researchgate.net/profile/Mikhail_Borisenkov/publ... Others have also attempted to estimate the amount of sleep of people in eastern vs western edges of time zones and they have found it to be some 20 minutes.
