> we find that an extra hour of natural light in the evening reduces sleep duration by an average of 19 minutes and increases the likelihood of reporting insufficient sleep.
The health benefits of people staying out longer and spending more money (?) are disputed I believe. The reduced sleep of day starting before sun-up are pretty universally recognized as bad for public health (particularly among teenagers).
Also note that if staying out longer was a goal to strive for, there are number of alternatives to encourage that. Including shorter worker ours, more public spaces, public events, etc. Conversely getting people to sleep longer is much harder with the clock set 1+ hour after the sun clock.
This are fantastic points I don't see in discussions around the topic. Goes to show that the solution space for a problem is often constrained by our perceptions of both the problem and what our expectations of a reasonable solution are.
But what I gathered is that what matters most for healthy sleep is not going to bed early, but rather to sleep longer in the morning and wake up with the sun. So if we move to permanent DST this behavior of staying up late might become more of a problem because of the early rising.
Permanent DST is the one where the sun rises later, which would mean easier to get more sleep rather than being woken up because the sun is rising too early.
Well, good thing we've never let that stand in the way of a decision. /s
Personally I'd prefer more light later in the day so that I don't feel like the day is over as soon as I get off work but that's just me.
