Please don’t do that. Sleep is really important, and waking up before sunrise is potentially detrimental to overall sleep in the population.

Yeah, uh, that doesn't work in northern Europe, or you'd have everyone asleep until 10. On a meta note: It is always super interesting to me how fundamental people think that day length is, if they've never experienced living at different latitudes. The variations are absolutely enormous, and create very different mindsets. That said, seasonal mood disorders are very common in northern Europe for a reason. Going to school or going to work hours before sunrise in the winter is just the way of things in northern Europe. You don't have a choice in the matter. The flipside is that having full daylight at 10 in the evening during summer is also just the way of things, and the almost non-existant night is a complete mindfuck for people used to less variations in day length.

  you’re not wrong, however this is a gross oversimplification. If you are on a permanent daylight savings time at high latitudes, you will have more people staying up late and waking up early for a longer period of the year. The difference is not negligible. In fact Iceland (currently on permanent daylight savings time; where I have lived most of my life) is considering moving the clock closer to solar time. They are citing public health reasons for the move.

Also do check the daylight graphs I posted in other comments, but here's an example from northern Norway: https://www.timeanddate.com/sun/norway/narvik https://www.timeanddate.com/sun/norway/narvik For a month of winter, there is no daylight at all. It is literally impossible to wake up after sunrise, because sunrise doesn't happen for an entire month.

  In all fairness, that's northern Norway which is not where most people live. But the general point is valid. It's mostly the northern mid-latitudes where people want to optimize the clock relative to the sun for different times of year. Further north and further south, it doesn't matter as much (for different reasons).

  The adverse effects of sleep deprivation accumulate. It does make sense to minimize the time you have to wake up before daylight.
