Thanks! Bought it.

Nice patience, just like a good value investor waiting for your price! I bought it two days ago  :(

LOL, thanks. I buy some books at full price too...  ???
Got $5 for ebooks if you spend $20 on ebooks deal expiring tomorrow. Not sure if I'm gonna figure out another $15.01 to spend on something.  ::)

That $20 promotion is why I went ahead and purchased Why We Sleep. Each semester I give a couple of lectures (This Spring will be my 76th semester teaching!) on "How to Learn." One think I talk about is thet the role of sleeping for learning. So I wanted to read "Why We Sleep" during the Holiday break to see if there is anything I can add to my lectures.

Wow! That is impressive.

If possible, could you please share any details for those of us who are not in a position to take your course? Any pointers to blogs or teaching material you can share would be very helpful. If it is an online course please do provide links.

Always interested in the "How to Learn" category both for myself and for my kids. And I am sure many board members would likewise be interested.

Thanks

Liberty,

Thanks for all the bringing all the sleep resources into this thread. Very helpful.

I know you have mentioned something about Vitamin D. Could you please share any resources that you found helpful in this area?

I mostly follow the evolutionary logic that it is best to be in line with whatever humans have evolved over the thousands of years. This goes for both diet and sleep as well and your thinking seems to be similar as well.

What I do not understand with Vitamin D debate is how we might not be getting enough of it. Is it related to not being as much outdoors? Sorry for the diversion, but if you want me to send a PM, I would do so.

Thanks

I'm actually working on making these more polished and updating the material. When I do and get them recorded, in a couple of months, they will appear at https://nanohub.org/groups/u

But for now,

^I guess it's back to the basics.
Here's a recently updated link that needs further updating, as far as the 2010 reference is concerned:

Indeed, we're indoors a lot more, wear more clothes, many of us live at higher latitudes than is ideal, etc. We also produce less of it as we age. Ideally, you'd get a blood test to see your serum levels and then take supplementation to bring your levels to within the optimal range (take gelcaps - not dry tablets - at mealtime, as it is fat-soluble and better absorbed with food).

I don't have the studies and research I did at the time handy, but that should all be fairly easy to find. I take 5,000 UI/day during the summer and 6-8,000 UI/day during the winter (I'm a 6'1" male in Canada, YMMV).

On a related topic, what do you think of need for sunscreen? It seems to me that humans have evolved to be in the sun, so cannot see why it would be needed. Any thoughts or research you have done on this?

I've seen both sides of the argument.. I ended up falling on the side of using sunscreen and getting more Vit D through supplementation.

I think humans throughout evolutionary time mostly didn't live long enough to worry too much about skin cancers and skin aging (the sun will make your skin visibly age much faster), a lot of the problems happened after reproduction age, which is an evolutionary blind spot, and throughout most of that time most humans probably had darker skin pigmentation than I do, which also provides some natural protection. There's also issues with the ozone layer being damaged in post-industrial times (some of that has been partially corrected by banning CFCs and such, but not entirely).

That's my vague understanding of the situation. I still get plenty of sun without sunscreen, but if I know I'm going to be out for a long time in the sun not being covered too much, I always try to wear good sunscreen now.

Excellent points! That makes a lot of sense.

I was recently talking about evolution with a biology professor and she made the point that evolution cared (in terms of increasing your chances of survival) only if it helped in reproduction. That is why women live longer than men, because older women help their daughters care for the children, which in turn led to women having more children. So evolutionary wise there is an advantage for mothers to have their grand mother live longer. Men, apparently no so much :)

Thank you!

It's not quite as simple as that, but yes, things that tend to happen after reproduction don't get encoded (or at least, not directly, which also leads to the interesting stuff in epigenetic).. That's why aging and the diseases of aging aren't programmed, but rather, a blind spot that evolution hasn't had a time to solve against because for most of humanity's existence, there were few very old people, and they didn't reproduce. There can be secondary effects, like having longer-lived adults helping the germ-line indirectly (ie. grand-parents increasing the chance of survival of their grand-kids).. I'm no expert, but I remember that at the time (10-12 years ago), I learned a lot from this series of posts:

Of course reading Darwin's Origins of Species is recommended as a good starting point, but this book is also a good place to learn:
