This is what we're working on at https://soundmind.co https://soundmind.co - improving the efficiency of deep sleep by monitoring your brain for slow wave sleep, and using auditory stimulation to increase delta power.
We're about to begin testing with our first users in the next few weeks.
To answer your question about evolution, I speculate...
1) the evolutionary element was likely only adapted to impact mothers, and still impacts mothers more than fathers. But fathers (I believe) are now more involved.
2) for mothers, less sleep may be linked to less memories of the pain of early child rearing, which may make them more likely to have more children.
Lastly, new mothers had a (if I recall correctly) 15% chance of dying during childbirth or shortly thereafter. From an evolutionary standpoint, the mother had mostly done their job, as long as a village was left to raise the young.
The priority for evolution was to get the child through the first year or so with the mother intact. Beyond that, mother nature didn't prioritize the mothers health over their offspring.
- DaveExeter 4y ago>Lastly, new mothers had a (if I recall correctly) 15% chance of dying during childbirth or shortly thereafter. .85^4 = 52% chance of surviving 4 childbirths. Does that seem right? The figure I've heard is 2%. About half of children died before maturity, so each women had to have 4 children just to keep population stable.
- pedalpete 4y agoYou're closer to being correct than my initial estimate. I was taking the average number of children born to a woman at 8. The population wasn't stable, it was growing. Mortality during childbirth either 1 or 2%. So somewhere in the 12-15% range that a woman would die of (one of her) childbirths. So, yeah seems about right. What is .85 in your calculation?

I don't have a typical sleep schedule though.
- pedalpete 4y agoAll our units are spoken for, and we have a LONG list. If "not a typical sleep schedule" means working shifts or something, research has shown that day time sleep is not as impacted by slow wave enhancement (what we do) as night-time, so it appears the stimulation is not ideally suited to shift workers. Having said that, I haven't looked closely at the protocols of those studies, but one of the researchers we collaborate with is strongly convinced that daytime sleepers is not a good target for us.
