This reminds me of a section of the book "Why we sleep"[1] that said similar techniques could enhance an older persons sleep quality. (I don't know the title of the study unfortunately.) It looks like this is an exciting area of research right now.

While alcohol will help put you to sleep (so will a concussion) it inhibits the restorative function of sleep. (1,2,3)

I’m all for the hedonistic rationalization for alcohol. We all need a release. But it is disingenuous to say alcohol has any positive effects beyond that. It is no different than sugar in that regard. My Saturday night cheat meal is filled with both, and I always look forward to it. But I don’t try and pretend that it’s in any way good for me (beyond psychological).

To that end, I completly agree with you that there are plenty of people who enjoy a few drinks without any real damage. I'm saying classify alchohol for what it it. The tobacco and sugar (4,5) lobbies love to pretend that they are something which they are not to sway public opinion. That is dangerous to society.

1. 2. 3. 4. 5.

Sleeping has a huge impact in procrastination. The lack of sleep translates into an hyperactive amygdala (which has a big influence in processing emotions and impulses) and an under-active frontal cortex (which influences our rational thinking, etc) [1]

According to my experience, a good night of sleep is the best cure for procrastination, sadly, our current society don't optimize for sleeping well.

Highly recommend Spark! If you like the topic of Sleep, check out Why We Sleep by Matthew Walker:

I am just finishing reading the fantastic book Why We Sleep [1], and as in so many well-meaning studies and articles, I can't help but feel like this effort is misguided. Just like an addict cannot accept help until they want it, I don't see how "adjusting" work schedules for those who don't even understand their own biology can possibly be helpful.

I've ALWAYS considered myself a night owl. I'm still not sure I'm not. But I've spent the past year rising earlier than I'm used to, and the past 7 months rising even earlier than that due to an enforced carpool with my wife. For the first time in my working life, I HAVE to be awake at a certain time (incidentally, far earlier than I'm used to). Instead of snoozing for an hour, I bolt from bed far earlier than I want to. I go to sleep marginally earlier. But my routine is regular I'm happier. I feel better. I feel healthier. I started reading the book and am acutely interested in tuning my sleep times to make this work even better.

Maybe I've never been a night owl. Maybe I've just had horrible sleep habits. Or maybe I AM a night owl, and I'd be even better off than I can possibly imagine, if I take all of these habits and processes and move them later in the day.

But I just feel like you can't possibly know if you're a morning bird or a night owl until you're already, consistently, religiously, getting enough sleep every night, on a consistent sleep/wake schedule.

Michael Pollan: How to Change Your Mind [1]

Not just about an utterly fascinating topic (psychadelic drugs), in terms of history (LSD turning from a scientific wonder drug to illegal), his personal experiences, and the neuroscience behind it, but also just extremely well-written -- a real page-turner. A crazy potent combination of science, spirituality (from a skeptic), and narrative. I expect his book will be a significant part of why psychadelic drugs will be legalized in the near future specifically for therapeutic purposes.

Also +1 for 2017's Why We Sleep [2]. After reading it, I couldn't believe how shockingly ignorant I'd been of how I spend a full third of my life, and how much it affects the other two-thirds -- and the degree to which a lack of sleep prevents us from perceiving the effects of lack of sleep, in a kind of vicious cycle.

I read this book "Why we sleep" by Matthew Walker [0], which digs into a lot of detail about sleep and what we understand about it. And, there are a bunch of things I learned that I have incorporated into my lifestyle now.

- Effect of coffee on sleep: I didn't particularly have problems with sleep but I have stopped drinking way too much coffee, specially late in the day, after understanding its effect on sleep suppression and the ill effects that causes.

- Importance of sleep: I try and get enough sleep and try to maintain a steady sleep cycle as much as I can.

- 2 hours of lost sleep is lot more than 2 hours of lost sleep(say by waking up early for a meeting): Sleep comprises of multiple REM and NREM cycles through the night, some cycles are heavier on REM while other heavier on NREM. And, both are very important and serve different functions. If you miss a couple of hours of sleep, its effect is lot more than just a couple of hours of lost sleep because you didn't get enough of either REM or NREM sleep. And, its not something you ever can get back.

- I used to think its something to be proud about, to be able to function without sleep or by skipping sleep etc. (specially when I was younger), now I think its just stupid :)

Apart from these, its a fascinatingly interesting read, I definitely recommend the book.

I highly recommend the 2017 book "Why We Sleep" [1]. Written by a doctor, starting at page 335 he calls exactly for ensuring hospital patients can sleep, why this is so critical for recovery, and how many things in hospitals currently work against this. (The book covers so much ground, including other reforms like school time starts, why society doesn't value sleep because sleep-deprived people don't perceive their substandard performance, and so on.)

"Why We Sleep", by Matthew Walker [1]. I've read a lot about sleep over the years, but I still found it fascinating and comprehensive.

I've mentioned the book on several other threads [2], so I'll avoid repeating here.

Along the same lines of expanding the ability of your body/mind, one that I'm currently reading is "What doesn't kill us" [3]. Pretty fascinating to think that we have a lot more control over our immune system than originally thought.

In my experience and the research I've read, you've almost mentioned all the top relevant reasons: alcohol use, stress, and reduction in sleep (kid being born). It's unlikely to be age.

I'd highly recommend last year's "Why We Sleep" [1] for more info on memory performance and how it's impacted far more that you'd suspect by full (and quality) sleep, which is in turn impacted far more than you'd suspect by alcohol and stress (not to mention kids).

Every single person here, if your serious about diving into the science of sleep, should read Matthew Walker's book: Why We Sleep:

His interview on Joe Rogan is a good summary:

He covers everything from why we sleep (obv), naps, melatonin, etc. I've just finished it and really enjoyed it.

It does get better with age in that your circadian rhythm will shift as you get older. It's a crime that we force adolescents to wake up far earlier than they are biologically wired to just so their parents can get to their jobs. According to Matthew Walker (Berkeley professor and sleep researcher), waking up at 7 is equivalent to an adult waking up at 5. Highly recommend his book on sleep. It's incredible, the best non-fiction I've read in the last couple years.

I would recommend reading Why We Sleep by Matthew Walker instead. [0]

The Promise of Sleep is an okay book, but it is almost 20 years old now and it shows.

I have read both books and it is remarkable how much more we learned in the time between them.


This was also discussed in a good book about sleep I read a few weeks ago: Why we sleep
And if you want to learn more about why its important to sleep, you should read the book "why we sleep" which is where I found this list.
I am more than half way through the book "Why we sleep?" by Matthew Walker and it is not a surprise to me that misalignment of circadian rhythm with class schedules results in poor grades. The book goes into great detail on the importance of getting eight hours of sleep on a regular schedule. Getting less than eight hours of sleep is tied to every imaginable disease and poor memory. I highly recommend reading the book.

~8.5 hours.

Most of my life I did the typical not getting enough sleep and then binging on the weekend, which doesn't work well at all. Since reading "Why We Sleep"[0] though, I've changed my lifestyle to prioritize getting quality sleep every single night. That book was pretty eye-opening in obliterating a lot of myths I believed about sleep and then teaching my how complex and important it is, indeed it is just as important as waking time if not more. The idea that time spent asleep is "wasted time" is now absurd to me, as so many bad things happen when you short sleep.

Since getting quality sleep regularly it's been like unlocking a superpower: retaining more information, better progress with strength training and skill-based hobbies, more solid emotional balance and way more motivation / inspiration at work.

Can't recommend that book enough.


krausejj · 2018-01-04 · Original thread is a fantastic new book on the subject, if you're interested in going deeper

Interesting. Have you found a difference in your sleep patterns since getting the treatment? One anecdote I've heard is that people on the spectrum have difficulty entering REM sleep[1]. Since REM sleep is partially initiated by eye movement, it makes sense that forehead and sinus shape could impact it.

I can highly recommend the book - Why We Sleep - mentioned at the top of the video. It goes into quite some depth on the reasons for and mechanics of sleep in a way I found approachable for someone with only a layman's understanding of chemistry:
