I tried polyphasic sleeping for a while when I worked at an IBank. I remember it as one of the most productive periods of my life but it was incredibly anti social and got the strangest looks from management.

I'd do 35 minute naps with an alarm at 0430, 0830, 1230, 1630, and without an alarm at 2030 and 0030 (on the basis that I thought my body would sleep through if I was "doing any damage").

It made going out at the weekends or playing poker in a casino incredibly difficult so after 3 weeks I had to pack it in.

I was lucky to live a 5 minute, folding, bicycle ride from the office but I also had a little card I'd leave on my desk for the corner that said, "I have not collapsed I'm having a nap."

The one thing I've kept from those days is that I still wear a sleep mask to bed.

Ah, I did it for a year and started before my first child was born. At 3 weeks my body finally transitioned to polyphasic sleeping (similar time as to the transition to dvorak typing) and I was finally functioning through all the sleep deprivation. Concentration was similar to monophasic sleeping.

I could take care of the baby while my girlfriend was sleeping at night and I could go out or work on my hobbies all night (with 27m naps) without any problem. It was like I was a liberating experience, I watched the whole of society shutdown at night, but I was awake every day all by myself, it was very odd. I also realized I didn't really need a house if I could sleep anywhere, except in winter - but I started thinking I could just sleep 30m here and there (in trains, at work, in the park on a bench) perhaps with electric blankets. A real nomad lifestyle. I also noticed that I had to force myself being productive at night as my executive function wasn't quite there - it was like my mind was used to doing nothing consciously at night, an unconscious part didn't really see a point in being awake and doing things at night - so I mostly just was sitting there, contemplating or meditating. When I made a todo list it was better.

As I also had to organize naps outside and at friends and family places it caused some tension and conflicts (I can tell some really wild stories) - and eventually, also because I didn't want to risk potential long term issues I went to 2 naps and eventually 1 nap each day.

Regarding 35 minutes, you risk entering deep sleep with 35m, at least I did when I went over 30m a nap. Or did you mean 25 minutes?

I found it would typically take 5-10 minutes to fall asleep. The one thing I did notice, that was really weird, is that as I fell asleep I'd have trouble "remembering to breath". Which was quite a strange experience.

I once got woken up by a security guard in the casino as I was taking my 35 nap sitting up and I found when I just said the phrase "medical reasons" he backed off.

Have you considered getting tested for sleep apnea?

Re:Regular afternoon naps linked to improved cognitive function by cornel_io on Sunday January 31, 2021 @07:46AM (#25978403)
Having had similar issues, "forgetting to breathe" usually gets diagnosed as central sleep apnea, which is usually associated with heroin abuse or heart failure. In my case neither was true, so docs generally threw their hands up and said "huh, weird!".

In addition, the therapy they recommended (bi-pap or something like that, basically a two-way assisted breathing machine) did absolutely nothing for me.

What finally helped was a min dose of an SSRI, which I started for totally unrelated reasons. Guess it was anxiety, never got any confirmation from any doctor that this is a known presentation of it, but swear to God literally two days on the stuff made me sleep easy with no breathing problems whatsoever. After six months I got off and once the withdrawal symptoms broke (real bad in my case, which is super weird for a min dose, but :shrug:) I've never had the problem again.

Sounds like an experience of

https://en.wikipedia.org/wiki/Sleep_paralysis#Threat_hyper-v...

As one falls asleep one loses the ability to voluntary breath. This can cause sensations of suffocating and resulting in panic if experienced when still conscious.

Re:Regular afternoon naps linked to improved cognitive function by orand on Monday February 01, 2021 @12:32AM (#25985842)
Yep, bi-pap is the intermediate machine that insurance protocols force you to try and fail on before they’ll approve the machine that actually works for your condition: ASV (Adaptive Servo Ventilation). It’s crazy expensive if you buy it new, especially if through a DME vendor. But you can buy them used with minimal hours on them for $900 or so, which is what I did. It actually works for me.

Very interesting. I wonder if this helps to explain why I'm not all that productive when experiencing insomnia, even on the occasions when I say "okay well if I'm gonna be wide awake, I'm gonna get some work done on xyz"

Re:Regular afternoon naps linked to improved cognitive function by mech422 on Saturday January 30, 2021 @07:15PM (#25974400)
I have just the opposite reaction...I get much more productive late at night. Possibly because of lack of distractions.

I worked midnight-8am for 10 years right out of high school, and now, if I'm not asleep by midnight my body just 'revs up'.

Re:Regular afternoon naps linked to improved cognitive function by etothepii on Saturday January 30, 2021 @06:56PM (#25974283)
Sleep Hygiene and Reading are my saviours here, I have a rigorous sleep routine. Phone on charge in different room, electric blanket on, ablutions, kindle for some fantasy (a change from heavy reading), then if I make it to 30 minutes (I set a timer on HomePod) I set a sleep timer with the Podcast "Sleep with me" on HomePod. I never get to the end of my 25 minute timer.

I used to stay late and do school projects at night (mostly programming). I always felt my mind is so calm and with no outside distractions I was able to focus very well and be very productive (may not be objective truth at all though).

Re:Regular afternoon naps linked to improved cognitive function by treeman79 on Saturday January 30, 2021 @08:08PM (#25974714)
Was same teens and early 20s. Daytime Has never gone well for me.

I would use full black out blankets, ear plugs and noise canceling headphones with video game music.

Pair programmer was wonderful for me, as it kept me on task and I didn’t give into distractions as easily.

Later diagnosed as ADHD. Medication made a massive quality of life. Up until my body decided that stimulants are invaders and my immune system went bonkers.

Have you found anything that gets close to it?? I have quite bad gerd and so taking any medication is a quick way to end up on the toilet but I would love to be able to focus!

I have pretty bad acid reflux and my stomach often would get very acidic by the end of day. (Even if I ate nothing)

Fruit and yogurt helps me a lot.

I think it's because fruit doesn't digest primarily in the stomach, so it moves the pills faster into my intestines.

Not a doctor.

Re:Regular afternoon naps linked to improved cognitive function by socksy on Sunday January 31, 2021 @04:27AM (#25977426)
Atomoxetine (strattera) is a non-stimulant ADHD medication that might be tolerated better. Additionally, I noticed that stimulants don't upset my stomach nearly as much if you take it with a substantial meal.
Re:Regular afternoon naps linked to improved cognitive function by hntrader on Saturday January 30, 2021 @04:26PM (#25973159)
You're blessed to be able to get to sleep so rapidly. For me, the stress of that type of job + coffee would kill that ability. Even without these two antagonists I would have no hope of being able to do that.
Re:Regular afternoon naps linked to improved cognitive function by pmiller2 on Saturday January 30, 2021 @04:46PM (#25973313)
I don't know if there's definitive research saying this, but this ability to fall asleep quickly may be due to sleep deprivation. However, polyphasic sleep is linked to lower academic performance and increased daytime sleepiness. [0] That makes me think that the "benefit" is possibly an illusion due to the antidepressant effect of sleep deprivation.

Coffee is the killer here. I never ever used to nap. I quit caffeine almost a year ago, and within a month of quitting, I started enjoying the occassional mid afternoon nap. Not everyday, just when I was tired. It's nice to know when I'm tired actually.
Re:Regular afternoon naps linked to improved cognitive function by tubularhells on Saturday January 30, 2021 @04:45PM (#25973299)
Have you ever tried? Coffee is easy to cut. Just don't have any at home.
Re:Regular afternoon naps linked to improved cognitive function by hntrader on Saturday January 30, 2021 @04:48PM (#25973322)
Yeah, it still takes me 60 minutes to sleep, because my mind is busy. I need meditation, medication, or something.
Re:Regular afternoon naps linked to improved cognitive function by gamegoblin on Saturday January 30, 2021 @04:56PM (#25973380)
YMMV, but I would also try cutting out sugar, and adding melatonin. I cut out caffeine and sugar about 5 months ago, and consistently take 3mg of melatonin 1 hour before bed and went from 60+ minutes to fall asleep to less than 5 minutes.

Apparently insulin regulation plays a big part in sleep quality, hence the effect of sugar. Another nice side effect is I've lost about 7kg without counting any calories or making any real effort to.

Re:Regular afternoon naps linked to improved cognitive function by lowercased on Saturday January 30, 2021 @05:31PM (#25973683)
Throwing in a bit more with YMMV...

Xmg of melatonin is hard to measure, because there's apparently not great accuracy in most OTC pills. And... it may take you days to confirm if a specific pill is 'working' well or not. If/when you find a combination, buy a bunch to have on hand.

I recently received the book "why we sleep" and it discussed melatonin's process. If "1 hour before bed" works for you, that's good, but it never did for me. ~3 hrs did. Or... at least 2-3 hours at this time of the year. My routine has been taking a melatonin between 6 and 7ish, and by 10 I'm typically quite 'ready' for sleep, and it's usually a fast process. It doesn't seem like it in the moment, but my wife has noticed I'm "out like a light" (which I think is more just in comparison to months ago).

Re:Regular afternoon naps linked to improved cognitive function by tubularhells on Wednesday February 03, 2021 @09:22AM (#26013791)
You can buy liquid fast acting melatonin. I take a pipette 1 hour before bed time and by the time I got the pillow, I am so sleepy I fall asleep instantly and do not wake up during the night.
Re:Regular afternoon naps linked to improved cognitive function by ralphstodomingo on Saturday January 30, 2021 @11:24PM (#25975922)
I would suggest you also look at the criticisms about the book you mentioned, Why We Sleep. I'd take the book's conclusions with caution.
Re:Regular afternoon naps linked to improved cognitive function by lowercased on Sunday January 31, 2021 @01:16PM (#25981055)
Have read some - it's not a panacea for sure. It did recently renew some interest in the subject for me, but yes, take it with some caution, certainly. It did make me re-evaluate some of the things I was doing re: sleep, and I've generally had somewhat better results since making adjustments.
Re:Regular afternoon naps linked to improved cognitive function by michaelcampbell on Sunday January 31, 2021 @09:30AM (#25979052)
I bet you could quarter your melatonin dose and still get the effects. Do some reading, but 3mg (although a common OTC dosage) is pretty high.
Re:Regular afternoon naps linked to improved cognitive function by matwood on Saturday January 30, 2021 @07:41PM (#25974564)
My sleep trick is to read a book. It slows my mind and is easier to stop at any point once I’m dozing off.

I also have all phone alerts etc stop a 9pm.

Been the same forever but I’ve recently found 5-10 minutes of deep, slow, and focused breathing (in through nose, out through mouth) results in me falling asleep very quickly after.

Re:Regular afternoon naps linked to improved cognitive function by baseh on Saturday January 30, 2021 @08:22PM (#25974801)
Caffeine before noon or sticking to a last call at 2pm kind of help me. Medication wise I tried CBD which seem to help sleep a little better. YMMV.
Re:Regular afternoon naps linked to improved cognitive function by pinipedman on Sunday January 31, 2021 @07:17AM (#25978257)
Enough exercise, or physical activity of any form, will fix this. The time and motivation to do enough is the challenging part.

The modern WFH culture has probably made it easier to do that than ever before (plus the lack of social schedules from the lockdown).

I did a modified Uberman sleep schedule while I was home taking care of my dad & working - the forced isolation, the fact that I would have to wake up every 3 hours to check on him & living in India, while working US hours anyway messing up my schedules of sleep supported the transition.

The process took almost two weeks to get into it, but lasted a whole two months & if I had to go back to it, all I would add to it is some exercise to sync up with the sun rising.

I think we as a species are naturally capable of doing short nap rests, at least for periods of several months, because that schedule of ~1 hour of rest for every 3 hours is literally what taking care of a newborn demands.

Since it was for such a short period of time it's possible you just had sleep deprivation, which can be used to treat depression and cause a big uplift in mood.

I tried bi-phasic for awhile. It worked great for me, but not so much for my family. My son's off at college now and I mostly work from home so I may give it a go again.
