Guest guest Posted September 15, 2002 Report Share Posted September 15, 2002 The alerting mechanism that regulates when you're awake and when you sleep become weaker as we age. CRON should slow down the degeneration of this mechanism too. I hate to sound like a broken record but if one hasn't read the book (The promise of sleep, Dement) you are missing an opportunity to optimize this roughly 1/3 of your life, with significant impact on the whole. Recent mouse research (not in the book) has shown that the brain rebuilds glycogen stores during sleep. This is very preliminary research and difficult to draw conclusions from, but feeding to the extent that it affects available blood sugar "might" affect amount of sleep needed. A sleep researcher commented on a study reducing sleep to 6.5 hours or less found potentially harmful metabolic, hormonal, and immune changes in test volunteers.. changes that mimicked normal aging (per Eve Van U of Chi, not in the book). A '99 study of 11 healthy lean young men linked insulin resistance to several nights of sleep restriction. In another experiment men who were held to 4 hours had reduced leptin concentrations (that would stimulate appetite). A study at Penn St. linked modest sleep deprivation with low grade inflammation, increased cytokine IL-6. Perhaps A.P. can flesh out these studies for any interested. (This is not from the book). What is in the book is practical advice that should be useful for everybody. The ability to fall asleep when you want to is dominated by synchronization of your alerting mechanism cycle with your particular daily pattern, pre-retirement mental stimulation, etc. JR ps: No I don't get a kick back from sales of this book, it's just $20 well spent. -----Original Message-----From: Francesca Skelton [mailto:fskelton@...]Sent: Sunday, September 15, 2002 9:34 AM Subject: Re: [ ] sleepHi Joanne: CRONIES usually get along on less sleep so perhaps you'reconfusing that with "mild sleep problems"? Mine started pre-menopausal andpre-CRON and seem to be what happens with sleep with many people as theygrow older. I thought perhaps CR would help, but it hasn't. Bob Apple and I had manyon and off list conversations about this and now that he's back on the list,perhaps he'll have something new to add. Bob and I have tried just abouteverything to promote better sleep.on 9/15/2002 10:19 AM, somejoanne2002 at bhsnz@... wrote:> Just curious, did you have sleep problems pre-CR or only after you> started practicing CRON?

Guest guest Posted September 15, 2002 Report Share Posted September 15, 2002 No need to spend it. I just checked out a copy from my local library. For anyone financially challenged, your local library has almost any book mentioned on the list including Walford's. on 9/15/2002 12:02 PM, john roberts at johnhrob@... wrote:> > > ps: No I don't get a kick back from sales of this book, it's just $20 well > spent.

Well, this really is a chastening to me. On weeknights i sleep max 5.5 hours, sometimes i cut it back to 5 or even 4.5. Then on the 2 days of weekend i sleep maybe 10 hours. This works for me, but if there's evidence about negatives, i will have to discipline my habits - very difficult. I had not planned to read that recommended book - " doesn't apply to me! " , but now i have decided i will look into it. Well, this wouldn't be the first time i have adjusted my regimen following new information learned from the CR groups.

Guest guest Posted September 15, 2002 Report Share Posted September 15, 2002 The reports I cited were not in the book, perhaps Al Pater can chase down the details. The book deals more with basic sleep mechanics and disorders. Just like everything else there are probably age related and genetic differences defining what is best for each individual. The book will help you establish a healthy sleep pattern.
