This data is pretty dated. Your brain compensates. There’s something called REM rebound to where if you don’t get enough sleep, your brain will offload as much REM as possible to the end of your sleep, filling in the missing and crucial sleep cycle.
How does your brain know when the end of your sleep is?
Is your brain a separate entity? You literally decide when to wake to with alarm. Or if you don’t set a time, it wakes you after x hours, after it’s backloaded all the REM.
If sleep deprivation gets too bad, it’ll completely knock you out to get as much REM in as it feels you need to function, alarm or no alarm.
Studying neurobiology/neuroendocrine systems is a great way to question who really is in charge.
It’s a lot of work man. Just being human. A lot… of work…
Weird polyphasic sleep schedules take weeks to start working, so probably from patterns. Although if what op comment is true something else is happening too
Billions of years of evolution
So it just anticipates when my alarm is about to go off?
It could be you subconsciously thinking about it because of anxiety. It happens to me sometimes.
That keeps me from going back to sleep all the time. Like oh I have another hour? Then it’s 30 minutes to fall back asleep and then that’s only 30 minutes so better I just get up. I get tired by the end of the day a lot lol
Hmm I have my suspicions that this isn’t accurate
For me its just groggy regardless of duration
Have you been checked for sleep apnea?
Well now I’m going to ask about it
Getting diagnosed was very positive for me. I did a sleep study and I was stopping breathing like a dozen times on average per hour. Started using a CPAP machine and after getting used to it and training myself to keep it on through the night, I now actually feel refreshed after sleeping after years of wondering why I feel like crap all the time
This makes me excited to get my machine. I did a home test last week and stopped breathing an average of 35 times per hour over seven hours of sleep. Doctor wouldn’t tell me if it was bad or not just that it was well over the line to get a machine. Hoping to have one in the next week or two. I’ve been tired constantly for as long as I can remember, at least the past decade. Really hoping to have similar results as you have experienced.
i plan on getting checked for it as soon as I have the money. It’s definitely possible
Agree, any duration nap is a day ruiner
I wish there was an alarm that could actually detect when I fall asleep and wake me up at the appropriate time afterwards, rather than just trying to guess how long it will take to get to sleep and setting the alarm that way
Sleep as Android can do this
Naps are poison to me, even a short nap means I’m gonna be up far past my usual bed time and makes the next day absolutely miserable. I’m jealous of people that can get in a good nap and still keep their normal sleep schedule.
That’s our secret, we can’t sleep a normal sleep.
How about my 4 hour depression naps?
See if you can do 6 a day
You can’t be depressed if you’re unconscious!
Sad dreams?

“Drink away the part of the day that I cannot sleep away”
That will interfere with my 16 hour sleep.
Imagine being able to sleep for just a nap instead of sleep through every alarm for 6 hours
i literally have 5 alarms on my phone and 2 on my smartwatch and IT DOES NOTHING
My brain when I try to nap: “4 hours, take it or leave it.”
For me the key to a refreshing nap is not breaking it with an alarm. I can sleep 30mins or over an hour at noon and if I wake up naturally I need 5mins to “get sober” and then I am super refreshed. If I Set an alarm that wakes me up at a certain time during my nap I need waaaay longer so feel awake.
My grandmother used the keys-in-hand method. Sleeping on a couch with one arm with keys outwards. Once the hand let the keys fall she woke up. That was apparently perfect for her sleep cycle.
Interesting. I suspect keys would not be enough to wake me up…maybe a bowling ball…
I’d need the bowling ball to start a Rube Goldberg machine that flips me off the couch.
Now try to see if you can hold a bowling ball for the duration of trying to fall asleep
Woosh!
well, seems there’s a market for a small hand-held thingy that sets off an alarm when it hits the ground!
I’m not very convinced at least about the grogginess. Usually for me is mostly random, and the reason that I don’t risk any kind of nap unless I don’t feel a bit obliged.
Yes, so set that alarm just before you fall asleep!
Narcoleptic here. Not bad, but I’d jus… lik…t …ad…zZzZzZZZZZzzZZz…zZZZZz
Yep, straight to REM before my eyes close. No nap length feels good either. Even those adrenaline inducing micro-naps while driving.
Now with meds, naps aren’t even an option.
Why not eternity?
