I don't get this _at all_. I happen to live in Sweden, you know the dark, cold place.
We have extremely short summer nights, and I can guarantee you that the SUN is so much brighter than your puny lights that its just silly. Nobody (well, almost) complains about that here. There are even many different solutions to, you know, block light from coming indoors. Or are you really sleeping outdoors? It just sounds so much like hyperbole.
No doubt for a lot of people light isn't a problem with sleep at all, particularly for younger people.
That sounds like a measurable decrease in quality, but to be fair you're starting from a highly unusual baseline.
And I don't mean to be uncharitable, but when it comes to sleep effects (reported by others, apparently), I suspect that the light emitted from tower-mounted aircraft lights at a distance of five miles has a greater effect on their psychological perception than on their photon receptors.
The light "pollution" of a full moon is surely larger than the tower lamps. And more variable over the night (the moon moves, towers do not).
Of course it's neither a point nor a source, but in the night sky it acts like one.
In dark locations, the moon can be bright enough to cast shadows indoors.
Just this year a large wind farm has been built on that BLM land. The nearest turbine is over five miles away, so you can't hear them. But each one has a bright red light at the top, I guess to warn aircraft. Even so far away, with about 20 of those lamps visible it destroys the night darkness, not just for sensitive astronomy, but even for a good night's sleep.
I just feel lucky that I'm on the other side of the subdivision and can't see them. That was a close escape. But a few lights are encroaching on my previously pristine view in the far distance as civilization approaches. But I probably have a few years left of dark nights, unlike my West-side neighbors.
