They at least tried: "Results were adjusted for age, sex, ethnicity, and sociodemographic, lifestyle, and health factors."

I wonder if lifestyle or sociodemographic includes having specifically young children. That seems like a specific known temporary sleep disruption.

The cogort was 40-69 yo.

I wonder how this translates if the irregularity is by choice . I can certainly see why people working back to back night and day shifts, or otherwise frequently being at a sleep debt that was compensated for later, would die younger. But as a freelancer, my sleep schedule is more or less my own. I go to sleep when I'm tired and usually try to sleep as long as I want to. Sometimes that's 11pm-10am, sometimes 6am-11am…

After I quit my day job and started freelancing, I actually saw my sleep schedule worsen. It partly had to do with the initial lack of projects and clients, and other challenges of freelancing itself, but what I observed was that my day job's grind or regular schedule also helped my sleep schedule. However, I eventually overcame those challenges and created my own schedule to work with, and my sleep cycle became bett…

How did you fill your schedules despite your initial lack of projects?

That’s a bummer! Have you found out why that didn’t work? Perhaps something like caffeine or allergies was interfering with your sleep? If haven’t found out, I wholly recommend doing a sleep study if you can. It can shed some light on any obstacles you may be experiencing. I’ve never done one myself, but I know people who got enduring benefits from the insights of their studies.

In my case it's probably a combination of undiagnosed ADHD and "revenge bedtime procrastination".

Came here to post this. I remember once when going back on ADHD meds, a very smart doctor adding 5mg of Dexedrine. At 5pm.

I asked him why he would prescribe a stimulant so late in the day. His reply was simply "it's so you can think of one thing instead of all the things".

Worked for me.

Interesting, I initially thought this factor was probably negligible, because the cohort was aged "62.8 ± 7.8 years" (either before or after the 7-year observation period). I still think it's small, but perhaps not negligible.

I estimate that some 2-4% of the group could be heavily involved in caring for grandchildren, sorting themselves into the irregular category. It's well-known that school-aged children pass flu to grandparents [2], and then grandparents die, just in time for the 7-year post-birth observation window. The absolute death rate due to flu is 10^-4 to 10^-3 per year, which would be visible on the paper's mortality time course chart.

Estimation details:

* some 20% are grandparents (and very few are parents) of young children [0] * 20-50% of grandparents care for grandchildren regularly [1]

So maybe 4-10% of the cohort as an upper bound. If the birth rate is 12 per 1000 per year, and babies cause sleep disruption for about two years to two persons, then that's about 4% also, but perhaps mostly not the same age group.

Going to sleep now.

Does anyone else consistently get 6 to 7 hours of sleep no matter what? It doesn't feel optimal and I feel great on the rare days I get 8 hours, but I can function just fine on less. Also cannot easily fall back asleep if woken up which is really frustrating.

Same, let me know if you find a solution. My brain just runs wild if I ever wake up leading me to not fall back asleep

very cool that dst has been killing us all this time.

I live in an area that observes DST and since most devices does the changeover automatically I've never noticed the switch. Only notice when other people start moaning about it. Wonder if it affects certain people more than others.

Eh, you gotta be careful with One Weird Trick medicine. Once you get past painfully obvious problems, everything not currently easily fixed by modern medicine tends to be "well it's really complicated" sets of problems; there's not one Cancer, your blood pressure can be elevated for many reasons, syndromes like chronic fatigue are almost certainly a mix of dozens of problems binned together by common symptoms but wil…

The difference between panaceas and this is that the idea for extending life isn't to add something, but not to fuck an essential part of life. If you think of life as the careful coordination of millions of parts, then there will be a million of things that if you fuck up you will die.

Which is the model that matches acceleration of death rates as we age.

Just as a secondary data point. Without medication I have about a 32:12 hour cycle. Up for at least 30 hours and sleeping for about 12. I can function on 5 but I'm grumpy about it for a while. Always been that way. Completely inverted as well. Up all night and my body tries to convince me to sleep during the day but I'm just not able to for another twelve hours. I got fired from several jobs because of it. My folks w…

I relate so much. I'm on some heavy hitting medication to manage it which no doubt will have their own consequences for me. Feels like there's no winning.

Yes, what are the "heavy hitting meds" for sleep, please?
