I could do physical labor for hours. Code straight for hours.
But when I have to look after the 2 kids for 3 hours solo I'm totally exhausted. And I don't mean sit them in front of a TV - but actually try and feed them, change diapers, clean up after their messes, keep them entertained...
Weekends are suddenly way more exhausting than weekdays.
And then that compounds over weeks.
It's totally exhausting. The modern model is totally unsustainable/not scalable, but I'm not sure what the alternative should be.
1) Though they are comparing parents specifically, without the baseline of what the hunter-gatherer groups sleep was like without children, are they comparing hunter-gatherer group to industrialized people? Or are they comparing parenting?
50% of people rate their sleep as an F, and another 21% a D grade [1]. That feels likely everyone is failing at sleep, not just parents.
2) specifically in mothers, as motherhood has shifted later in life, the early years with young children are now often overlapping with perimenopause, so mothers are hit with the double whammy of sleep disruption. I blogged about this a few months ago [2]
The study is still mostly focused on the antiquated idea that sleep duration is a predictor of sleep quality. The latest research shows sleep regularity is a better predictor of morbidity than sleep duration. I wrote about hot the Neural Function of Sleep dictates this [3]. Studies in shift workers (I can never find the link) shows regularity trumps duration for both subjective sleepiness and cognitive performance.
The article does mention the increase in prolactin during breastfeeding, but the tiredness of parenting doesn't only last through the first year (apparently the average of breastfeeding in Australia is 6 months). The hunter-gatherer societies I'm sure breastfeed for longer periods.
I work in neurotech/sleeptech as the co-founder of affectablesleep.com and we have a keen focus on parents of young children and specifically enhancing the Neural Function of Sleep, not sleep duration which everyone obsesses over [4].
Until the advent of electricity, when it was nighttime, it was mostly pitch black dark, and there was nothing you can really do except go to sleep. These days you're up a lot longer and there are more distractions like work and social media to keep you up well into the night. If you ever go camping with no cell phone signal, you'll go to sleep much earlier as well and get a lot more sleep than modern living.
Speaking as a working father and stay at home mom couple, our lives completely revolve around the baby’s needs for many months after birth. I can’t imagine how challenging it would be to try to support both a newborn and each other as a dual-earning family. But I do think our arrangement, including cosleeping, and her not needing to be at work early, has helped immensely overall with our sleep.
> One study, for example, found that first-time mothers in Germany on average get an hour less of sleep per night in the first three months after their baby is born than they did pre-pregnancy. Fathers lose a third of an hour.
Yeah but how many times were they woken up in the night?
With a baby you might still get 8 hours total but you’re woken up 4 times a night which makes that sleep way less effective.
"It's not that modern parents are waking up more often. Work by Samson and others has found that people in hunter-gatherer societies usually wake more frequently through the night than we do."
But I think there's a difference between waking up at night because your baby is crying, calming them down, going back to sleep, etc etc. when you have a 9-to-5 job, versus if you're a hunter-gatherer.
I spend a lot of time in the rural Philippines and I notice that locals out here don't sleep that well and it doesn't seem to bother them. They get up extremely early with the sun, roosters are crowing even before that, cats are fighting randomly through the night, storms kick up many nights in the area through the year, and then they sometimes stay up late singing karaoke, though most of the time they are in bed early.
In compensation I noticed they nap frequently in the day time, often in the hottest part of the day when it's unpleasant to work.
It put my own sleep issues in perspective, I realized I had been a little too precious about it and I can indeed do fine on more fractured sleep. Often I form a judgment in the morning about my sleep and if I feel bad about it, I carry that through the day. I'm more convinced now it's a psychosomatic thing, I'm convincing myself I should be tired! So I try not to do that now and think of the people out here who live every day like this.
On studies showing napping increases lifespan and all the good things, a common complaint is that presence of naps is also an indicator of high socioeconomic status. This anecdote is a good counter to that!
The 9-5 is doing a major part of that comment. Irregular sleep isn’t the end of the world if you can sleep in and recover. Modern parents don’t get a chance to recover.
I dont know if "cannot" is the right verb here. I bet if you asked enough euromericans if they'd choose to live with extended family the answer would be "only in extreme and deprived circumstances".
Isn't a common excuse for not having children that couples can't afford their own home?
> Although sleep duration increased after an all-time low at three months, neither parent had fully recovered their pre-pregnancy sleep after six years.
Another reason to not have kids.
> Our ancestors may have simply had less practical need to sleep deeply in one continuous stretch. "They would not have had the pressure of having to work a nine-to-five or an eight-to-five job that required them to get a certain amount of sleep during the night to be able to function the next day and to function safely," Ball says. "They weren't driving cars. They weren't operating heavy machinery. The kinds of things that matter to us just simply wouldn't have been issues."
> On average, the German study, which looked at nearly 40,000 people in total, found that parents who had at least one child under six years old reported sleeping about seven hours per night. Non-parents received just 10 minutes more sleep per night, for women, and 14 minutes more per night, for men.
I'll trade 15 minutes of sleep for a lifetime of joy, thank you :)
Not sure where are those lucky ones, but I've met half a dozen parents that became literal zombies during the first years because of a lack of sleep. From what they've reported, 2 hours is a lucky night. It does get better later on, after 2(!) years.
My neighbors' first kid had colic and they said the baby slept for at most 20 minutes at a time the first year.
So yea I imagine that'll turn you into a zombie.
They also said after a year they got a tip about a chiropractor (IIRC), went there and after 5 minutes the colic was gone. A real mix of emotions they said...

A village where trusted neighbors and family members and a chain of kids in increasing ages can help look after each other.

How did get so lucky?

When I work from home and have a bad night, a 20-30 minute power nap during the day does wonders.
Clearly my anecdotes do not apply to the rest of globe, just my observation.
But most people cannot have those things in modern Euromerican nations
> most people cannot
I dont know if "cannot" is the right verb here. I bet if you asked enough euromericans if they'd choose to live with extended family the answer would be "only in extreme and deprived circumstances".
