You can have a time system based around sunrise. I mean with most clocks also being internet connected computers it wouldnt be too hard to make a system where you measure time in hours after average sunrise in a tike zone. That is where I live right now it's sunrise +3. I'll reschedule the daily 'standup' to SR+3.5, the banks open at SR+3 and close at SR+11. One major consequence I can see is that now we have north s…
That's what time zones are. You're just proposing more granular time zones. And none of them can fix the problem that in a lot of places the days are just short in the winter.

Re: The Economic Consequences of Increasing Sleep Among the Urban Poor
#172The majority of comments seem to have the belief that the need for 8 hours of sleep is truth, and seem to mostly be making up various excuses why the increase in sleep here doesn't show results. As far as I can tell, the 8 hours figure is on pretty shaky grounds and most believe it due to pop-science books like 'Why we sleep' and it could easily be the case that this is just another study showing how exaggerated that…
I need probably 7.5-8 hours of sleep. I'm very confident about this. If I get only 5-6 hours sleep for a couple nights, I become quite cognitively impaired; if it goes on long enough there are serious emotional effects too. There are people who insist that actually, 5-6 hours is fine, and that I must be lying, lazy, or deluding myself. These people are trying to make me stupid and miserable. It's an issue that provok…

Timezones don't account for seasonal changes in sunrise times, and DST is a poor hack that tries and fails. Using local solar time would be an improvement in that regard. On short days you just do less.

Long before that specific book came out. If you look at how they arrived at the recommendation here, a lot of it was based on discussions and voting by 15 experts chosen by the US Department of Health. Actual studies are much less conclusive (see the one we are commenting on for example) and the evidence for 8 hours of sleep is shaky and the difference from 6 to 8 is rarely especially big even when it is supported wi…
This is one of my favourite topics that seems straightforward (What's the optimal sleep length?) but is a lot more tricky. > If you go through actual studies and systematic reviews it is really hard to make much of a case that 6 hours is much worse (if at all) than 8, yet alone anything more than that. The absence of evidence that 6 is much worse than 8 hours is not evidence that 6 is not much worse than 8 hours. It…
If sleep studies show that 6-hour sleepers do better than 8-hour sleepers on a variety of metrics... that definitely counts as evidence.
It doesn't matter that much in this case because we already agree that it's worse
The parent comment literally cites a study that suggests 8 is worse than 6.

#175Those in the study were low-income adults in Chennai, India who sleep only 5.5 hours per night on average despite spending 8 hours in bed. The key takeaway was: > increased nighttime sleep had no detectable effects on cognition, productivity, decision-making, or well-being, and led to small decreases in labor supply. I find the result surprising. When I get under 6 hours I see a clear drop off in performance.
>In contrast, short afternoon naps at the workplace improved an overall index of outcomes by 0.12 standard deviations, with significant increases in productivity, psychological well-being, and cognition, but a decrease in work time.

#176In California, rental apartments are built to a lower standard than condos. In particular, they don’t require noise proofing between units. Noise proofing interior walls costs almost nothing (something like 1% the price of construction), but has a huge impact on quality of life. I’m continually shocked at the systematic discrimination built into California housing.

Good grief. It almost makes me question what information is missing from the abstract since I don't know how one can consistently run on fumes without it affecting cognition, productivity or decision making.
Throwaway as I don't want to admit that I feel permanently cognitively impaired. Anecdotal, but I spent years not sleeping through university and sleeping in airports or on the train. Studied engineering and did a lot of hackathons and events and stuff. I figured out then that I didn't need full cognition or excellent decision making. I needed more hours cranking out work. I spent years sleeping just a few hours and…

I don't understand. The study you cited, a meta-analysis, reviews the adverse effects of short and long sleep on * Mortality * Incident cardiovascular disease * Incident type 2 diabetes * Mental health (incident depression) * Brain health (incident cognitive disorders) * Cognitive function * Falls * Accidents and injuries and six other outcomes. The authors conclude: > Conclusion > A comprehensive body of evidence su…
I specifically cited the actual results from the meta-analysis. In the conclusion and abstract they seem to mostly talk about 7-8 vs really short or longer sleep but when you look at the analysis there's barely any adverse effects at 6 (and indeed 6 is better than 8 and only a tiny bit worse than 7 on the most important thing from most studies - all-cause mortality). Yes, of course sleeping, say, 2 hours a night is t…
> My claims and quotations were about 6 hours, which is roughly what the people in OP slept, too.
It's not clear how comparable the numbers are. The study from OP [2] reports sleep as measured by actigraphy (5.5h), time in bed (8h) and self-reported sleep (7.2h). What the meta-analyses most likely have studied (I haven't checked) is self-reported sleep.

>It's an issue that provokes a lot of strong emotions, especially on the side of people who feel pressured to sleep less than they need. Perhaps you feel like it is much worse for the side you perceive yourself to be on. I, and plenty of other people have had very negative experiences and sleep-related anxiety because of all the people insisting that getting less than 8 hours of sleep is bad for you on flimsy evidenc…
I think the reason "Why We Sleep" became so popular without facing much scrutiny is because many people were facing these pressures and desperate for some countervailing authority to point to.
