I was sleep deprived today (only 4.5h of sleep thanks to catching up on GoT season 7), and I think I was 30-50% slower than usual. I didn’t notice throughout the day, but I just didn’t get as much done.

#82I had to stop at "quasi-experiment"
Quasi-experiment is not necessarily a bad thing. It is to denote a study that does not have a traditional control-experiment structure with explicit pre- and post-measurements. This is particularly difficult to do with real time data analysis over time periods or with concepts that have ill-defined units of measurement.
For example, productivity and learning would be considered ill-defined. How can you prove more sleep makes you more productive? Since that is difficult, you can instead do a quasi-experiment or case study to observe the effects.

I don't know if you have children yet, but I regret to inform you if you don't that significant sleep deprivation is in your future unless you plan to extensively involve caregivers outside of you and your spouse.
Cosleeping can dramatically reduce sleep deprivation for parents. We humans have evolved to cosleep with our babies. In a cosleeping situation the baby does not experience terror (a baby left alone in nature has zero survival chances so this terror is programmed and so leaving a baby to sleep alone is counterproductive and cruel), can feel the warmth and heartbeat of the mother, can feed without and before fully waki…
Isn't the risk of accidentally suffocating the baby quite high when co-sleeping? I think I'd prefer a bed-side crib.

#84I'd love to see a modafinil, caffeine, and nicotine group added to this study to see if there's any difference. 50% reduction in quality is a lot!
Not enough subjects to test modalities while excluding learning effects and losing predictive power. If you did 4x as many devs then a factored design is possible.

#85I had to stop at "quasi-experiment"
That's just a bad name. This is essentially a nonrandomized unblinded controlled trial using representative sampling. Only two steps below a full RCT unless you suspect foul play.
I'm not sure how you'd blind lack of sleep and that's not the point, so the only issue is lack of randomization.
Much better than an observational study.

Can. Possibly.
Your mileage on this may vary, as I went something like 9 years over three kids without having significantly undisturbed sleep.

"as a serious health debt" Except, sleep isn't a debt because the loss can't be repaid. This is one of many important things I have picked up from Dr. Matthew Walker who wrote "Why We Sleep" and has been doing the podcast rounds lately. Not to pick on you at all. It sounds like you have made some big realizations and are making fantastic changes. Realizing I can't make up sleep to pay off the "debt" has been eye open…
> Except, sleep isn't a debt because the loss can't be repaid. sort of ? The impact of missed sleep has a half life. A single night of 4 hours sleep, followed by a year of normal nights sleep will lead to a me that is indistinguishable from the me that slept 8 hours that same night. I'm all for sleeping properly, but lets not suggest that it is the end of the world any time someone doesn't get their standard n hours

Usually. Except if the 4 hours of sleep leads you to crash your car, or run into a pedestrian, or forget your child in a car.
In the usual case, a day of missed sleep is normally OK, but when you are responsible for other people (rather than just code quality/productivity), why risk it? And even in the general case...why risk it? It is far better to lead a normal lifestyle and be at peak performance in all parts of your responsibility.

But that's just as true with credit card debt, right? If I couldn't make an important purchase because I hit my limit, my life might be radically different - is it therefore "not debt"?

Normally, the crib is attached next to the bed - with an open side facing the bed so that nursing is more convenient. They still sleep on the firm surface needed in a crib (to prevent suffocation, as you noted). That's still a lot closer and more comforting [for them] than having it be in a different room.

#90I've bought recently one of those cheap wrist bands. One of the most important features for me was ability to measure sleep quality in terms of "daily hours of deep sleep," whatever that scientifically means. Over the course of several months, I've been able to identify things which affect my sleep quality: * eating late: bad * drinking late: one beer... not really that bad * answering work emails until midnight: REA…
What is the brand of the device? I am interested in getting one. I'm struggling today after little sleep, but I would also like insight on how much deep sleep I am getting.
Apple Watch does the same thing, but you can choose from 3rd party apps as well.
