This practice hasn't entirely died out.
My principal memories of it consist of biting cold. Our dorms were unheated, so getting up in the freezing night was pretty unpleasant, and getting back to sleep was hard to say the least. While we were out the moisture in the room would condense on the iron frames of the bunks, and freeze.
Needless to say these days I do the standard 3am-8am God I feel fuck-awful "sleep" propped up with plenty of coffee.
It's almost a shame. Our lives there bordered on abusive in many regards, but it was brilliant - we were allowed to run around with rifles, go off exploring the countryside unsupervised, play with explosives, and the education was ridiculously good in hindsight. We had a lot of freedom within the rules - but if you broke them... Corporal punishment! Usually just a birch to the hands, and oh boy did it work - never got caught the same way twice!
I had no idea such schools existed, even 20 years ago.

https://en.wikipedia.org/wiki/Tikkun_Chatzot (Jewish prayer said about an hour after midnight).
I don't know if Jews had a different sleep pattern than their neighbors, but I can't imagine they would.
At the time the prayer was instituted Jews mostly lived in what is now Iran/Iraq and in Israel. They were expelled and ended up in Europe only later.
"In between the first and second sleep the person would be awake about an hour – enough to say prayers during Matins, which would typically fall between 2 am and 3 am, study or even have sex."
Why the even :-)? Shouldn't those three items be listed in the reverse order? Does this point to a fact about the medieval mindset or just to the sensibilities of the writer?
In the middle ages, you were religiously required to get up in the middle of the night to say a set of prayers. This practice was mandated by the authorities and failure to comply was not regarded well.
Articles about medieval first and second sleep tend to present this practice as if it is a natural human practice found in all cultures before the modern world.
The specific manifestation of first and second sleep in this era in europe though is clearly a result of authoritarian mandates of behavior that should not be neglected.

I use NRR 33 earplugs and at least one white noise machine going, sometimes two, to avoid any noise pulling me back from near-sleep. The room is dark, but I wear a sleep mask just in case.
I'm averaging 1-2 hours with those. I'm doing the sleep hygiene thing, where I don't do anything in bed except (try to) sleep and sex. I think you're also supposed to just get up if you can't sleep, but if I do that, I just never sleep. I come back even more exhausted, and I'm still looking at the same damn wait.
Mental activity can definitely make it worse, but I haven't found a meditation/visualization sort of trick that really helped. The best I can do is psyche away the frustration and just... wait.
Alcohol/pot help maybe a little, but then I don't sleep deeply at all, always wake up really tired. I haven't tried prescription drugs. I'm told they have the same effect on sleep quality, and I don't want that. I do get much-needed good sleep once I'm there. It just takes too damn long.
I'd love to hear if anything's worked for you.
If I go out on a long camping trip I'll often not even bring a book. This means that once the sun goes down there is basically nothing to do. After a day or two I find myself easily falling asleep and sleeping through the night. When I come back home, if I still haven't begun to go back to work, it persists. I can easily just go to bed at 11:00 and get up at 8:00. It generally lasts until I go to work.
It's the anxiety of needing to get things done and maintain my appearance to others and to myself that really seems to keep me up. As I lie in bed there's a part of me that says I should have accomplished more during the day and that I should be doing something "productive". I'm working hard on meditation, mindfulness and self-awareness to reduce the anxiety, but what works best is to really remove myself from the stressors and go to a place where I really just can't do anything so my mind gives up.
I went camping near the end of December and had another week off for the new year. It was great. I was well slept and relaxed. Now in my first week back to work I've already fallen back into less than 7 hours of sleep per night.
I guess I need to go camping again.
The sun is setting here at around 5:15 pm and rising at around 7:30. Twilight times are about half an hour more light around those times. If you're going to sleep around 6pm because the sun has gone down, you're probably not sleeping through until dawn which is 14 hours away. So you got up, did some stuff, it still wasn't light out, so you just went back to bed.
It's not because it's healthier, or because you evolved to do so, it's because your source of light hasn't shown up yet. That changed with cheap electricity, because even candles weren't quite as convenient or cheap.
I can't sleep a full night if I have more than 2 drinks, I imagine this happens to others as well.
Compared to lets say a regular siesta which many societies don't do, but I think we all have had or wanted to have an afternoon nap.
And saying "I hate waking up in the middle of the night" doesn't really have much to do with this. If you consistently slept for 12 hours a night, you might find it a lot easier and more pleasant to get up in the middle, and that's exactly what one of the studies in the Wikipedia article showed.
And as anecdotal evidence, even a few people in this 2-hours-old comment section say they've tried it with good results.
During the middle hour, I felt the intense relaxation and started writing poetry/drawing during the period. I'd often just stare out the window, enjoying the feelings of tranquility. I even wrote some code once that I'd been struggling with before I fell asleep. The dream recall is intense -- you can remember every detail, rather than fighting as it fades away -- so I also started keeping a brief dream journal.
I'd love to do it again, but it's not feasible given the rhythms of NYC. If I ever move someplace quieter and decide to simplify my life, I'd eagerly return to the segmented sleep schedule.
There was a year that I slept from around 3am to 9am, long-ish siesta in the early afternoon (1pm-4pm). It was the most productive time of my life, and I felt well rested. I really got a lot of work done in those late evenings/early nights; Everything calmed down in the dorm, noise outside was lower. Morning was for chores/part-time job.
I wish I could return to this. I'm more or less 9-5 now and always tired.
But we make it easier on ourselves by milking at 8 AM and PM.
but technology has also advanced to the point where each cow can choose its own frequency: https://en.wikipedia.org/wiki/Automatic_milking#Advantages
Apparently people from the middle ages still suffered from night tremors. Now that these sorts of things are better understood, quotes like this sound rather comical.
In January, like now, in Germany sunset should be at ~8 am and dusk should be before 5 pm. That's only 9 hours. I'm probably not working hard enough (physically) but how would I ever sleep that much?
In June there's daylight from 5 am to 9 pm, that's still 10 hours of darkness, I see how it would work there.
