When I had an important exam or something else I really didn't want to miss, I'd set an alarm for a while. But then I just went all in, and never set an alarm. That made me pay more attention to when I was going to bed at night, and the quality of my sleep. When I started working I would set an alarm for about half an hour after I typically woke up, just in case, so I wouldn't be late for work. But after six months of that, I stopped setting my backup alarm as well. I was late for work maybe twice in five years, and it was never significantly late, and it was at times where my body really needed sleep and it probably helped me avoid getting sick. These days I only set an alarm if I have to catch a 6am flight, or if I'm getting up super early to climb a mountain or something.
If you're battling your alarm every day, I highly encourage you to experiment with not setting an alarm.
The thing that works for me is waking up (with an alarm) every day at the same time (6 o'clock) including week-ends.
I have a "dawn simulator" clock so most of the time I'm already awake when the alarm rings. But no matter what, when it rings I get out of bed immediately. You snooze you loose!
If you know you have to be up by X then be sure to go to bed at X-Y. I would imagine the struggle is winding down for bed early rather than waiting till you "feel tired" to go to sleep. Artificial light and stimulation makes it easy to stay up way later than intended.
Once you're tired from waking early, you're far less likely to look at your phone too late.
However - then I started a job where I had to travel between time zones, and I still haven't figured out how to get the body to know that it's traveled quickly other than mealtime & nap manipulation the day before, and even then I still need alarms.
That’s what it felt like, like I had very limited time to shove x amount of things into my brain which only processes at y rate, so if I had too many things to shove in at a time due to taking a full courseload, that meant staying up since I cant change the rate my brain digests information without abusing stimulants like some of my friends.
So then you end up with a few nights of 5 hour sleep which you pay for by sleeping for 13 hours on the weekend. Not healthy, but it became a matter of necessity due to also having to make time for a part time job.
When I had sleep apnea I could fall asleep at any time of day, no matter how much sleep I got (or thought I was getting) each night. The alarm was necessary because I never felt well rested and couldn't get up without it.
Then I went for a sleep study and was told that during a night of 6-7 hours of what I thought was continuous sleep, I actually woke up 120 times. Eek! Of course everyone normally wakes up at least a few times and doesn't remember it the next day, but most people don't choke and stop breathing 120 times a night. I rarely got any real deep sleep.
I had sleep apnea surgery, which changed my life. Almost right away I got better sleep and was more alert during the day. It was like getting an extra 2-3 hours a day, every day.
Now I get up without an alarm every day and never need caffeine. It's a great way to live.
My biggest pet peeve is that it ignores the role technology (in the form of artificial light and comfortable indoor space) completely subverts our natural sleep cycle. It's a lost battle.
Better to accept that we're in an artificial state our whole lives and do our best to adapt to it. What I'm trying right now is a good melatonin supplement every night to counteract the unnantural stimulus, plus a magnesium supplement, and a lot of daytime exercise. This routine has gotten me from 6 hours of anxious sleep to 8-9 hours per night plus the occasional nap. And I feel great.
The main point of both your comment + the article (which, I also haven't been able to read yet) is that you need to find what works for you by trying things.
Personally, melotonin only gives me 6 hours of sound sleep (many times I have tried to get more, last night being one of them). But in 6 hours from sleeping almost like clockwork I will be awake- and quite wide awake. It ususally takes another hour to fall back asleep, or sometimes I just decide to be awake.
So personally, moving towards the no-supplement tact is appealing even if it is much harder in artificial environments.
the pandemic has let me play with sleep and sometimes it's to let it gradually drift forwards an hour each day and wrap around. (schedule meetings are the only trouble spot to that experiment)
I interpreted this in summary as "sleep when tired and don't sleep when not tired". Which seems like common sense. That's akin to my favourite feeding pattern, which can be summarized as: "eat when hungry, do not eat when not hungry".
Some stuff I got out of this:
1. The ideal sleep pattern is sleeping when tired and walking up without an alarm.
2. Biphasic is recommended. Homeostatic is how easy it is to initiate sleep, circadian is how easy it is to maintain it. Circadian cycle is usually nightly, homeostatic peaks with fatigue. It's easy to have a 20 min midday nap but hard to do a midnight one.
3. Brainwork is great as soon as you wake up, and if you need caffiene, this is the time for it. Bundle stress and exercise and keep it away from the night.
Take note this is all theory and not practical, and the author hints that society should follow these and not the other way around. It took me half a decade to find a way to fit it, and what I did was:
A. Force myself to wake real early, about 4 AM. You will feel horrible for a week, but it moves your circadian rhythm forward to wake and sleep naturally without an alarm.
B. Naps in the car at lunch. Waking early gave more time to cook, which means packed meals are done in half an hour, followed by a quick nap. I set an alarm but never need it. Exercise is easy; a quick run and a lot of strong deodorant.
