I think snooze alarms are stupid. If you need to wake up at 9, then just wake up. Why set it for 8 am and then grab your phone every few minutes just to hear the same damn alarm again? Just wake up at 9 and deal with it. Curse yourself for staying up too late but be an adult, get out of bed and start your day
<obligatory snark> Different people do things differently then you, dalej42. An adult would know that.
Why I specifically do it is because I like to wake up gradually. I don’t use my phone as an alarm, but rather a good old fashioned clock radio and it’s very pleasant to me. 
Because I don’t bound out of bed. I need some time to wake up and get ready to face the day.
So you don’t turn off the alarm and in a semi-woken state immediately fall back asleep, only to miss whatever you were supposed to get up to do.
I like to watch headline news in a bed for a bit before I get up and shower, but sometimes I drift back off to sleep.
For those trying to sleep off a pint.
With a snooze alarm, you never get quart napping.
My wives have always played snooze alarm, and I never understood it, either. As for me, I always wake up 5-10 minutes before the first alarm goes off. I leap out of bed as I have since I was a kid, get my shower, feed the dogs, clean the litter boxes, make the coffee, and…nnnow I know the point of the snooze alarm. Nefarious.
I use the snooze alarm because I wake up at the first alarm and immediately take a caffeine pill then go back to sleep. By the time the next snooze alarm goes off the pill has taken effect and it’s much nicer to get up. Sometimes this takes a couple snooze cycles. People act like caffeine pills are similar to methamphetamine and I’m weird for taking them but honestly it’s just a convenient way to take caffeine.
It comes in pints?
Yeah. 16 minutes extra sleep.
I haven’t used an alarm in 25 years, unless I have an early appointment, meeting, or travel plans that I absolutely cannot be late for. I just wake up when it’s time to wake up.
Although I have no criticism of people who use snooze alarms, I never really understood it either. If you have to be out of bed at 7:00, it seems that your quality of sleep would be better to sleep until 7:00 instead of waking up at 6:40, 6:45, 6:50, 6:55, *then *getting out of bed at 7:00. But different things work for different people.
Yeah, I never understood them either. If I need to get up at a certain time, I set the alarm for that time. If I don’t need to get up at any particular time, I don’t set the alarm.
But - yeah, different strokes.
I think it’s like this
“I have to get up at 6:00, do my math homework, then finish my French assignment, and then breakfast, shower, and hit the road”
6:00 a.m. “I’ll get math done at lunch, I can snooze”
6:10 a.m. "I’ll skip breakfast and then rush through the French thing. Just a few more minutes.
6:20 a.m. “I can probably do some extra credit this weekend in French, to make up for the fact I skipped this assignment.” Snooze.
6:30 a.m. “I showered yesterday.”
6:40 a.m. “I’m up, I’m up.”
Yeah, whatever floats your boat, but snooze alarms seem odd to me. I wake up before my alarm anyway, so I’m one of those people 
Now what drives me a little nuts, is my wife likes to set clocks 15 minutes fast, so “she has more time”. I won’t let her do it with any of the ‘house’ clocks (it’s the one thing that I put my foot down about), she just does her car and alarm clock. She is one of the most punctual people in the world. Always has been, has no problem being on time even when using an accurate on time clock. I just don’t get it.
Back in the day I somehow ‘trained’ myself to get some form of quality sleep effect in the between snooze alarms. If I hit snooze about 4 times I had a better feeling morning than if I just sleep that added 40 minutes. No idea, but I never felt that I was fully back to sleep as I could remember mrAru or the roomies at the time pottering around making noise.
I used to get peeved at an ex - he liked the Taxi theme as his wake up gradually music. It usually put me back to sleep. I had to have him add a second clock for me that would full on alarm at the time he was fully awake just so I wouldn’t end up late to work.
I have to wake up gradually. Used to be that I needed a two-hour alarm because the first 90 minutes or so simply wouldn’t register in my brain.
Speaking as an actual, bona fide adult, some of us have in the past demonstrated the ability to hear the alarm, get out of bed, walk across the room, turn off the alarm, and get back into bed all while still asleep. By reprogramming that part of my brain to use the snooze instead, I get multiple chances to actually wake up.
That, and some people’s brains aren’t wired in such a way as to be able to go from zero to sixty in zero seconds - superior minds like mine (:D) will often find themselves jolted out of sleep at some bad point in the cycle and, without giving the brain a chance to reset and retry, will result in me being half-asleep the whole morning. Give me a few snoozes and my brain will have had time to prepare for the rude awakening and come awake cleanly.
ETA: And it’s weird to me that you people are all posting even time estimates for snoozes; mine is nine minutes and I gather that that’s pretty standard.
This sounds like me as well. A while ago I wanted to know how I was able to do this - turns out I am having “micro”-wake-ups thru the night to glance at the clock and gauge how much more time I have before I need to get out of bed. Not a great way to get deep sleep, but seems to work.
Because sometimes you need that extra ten minutes to decide if you want to go to work or jump off a bridge.
