Francesca,

I think that you are right in mentioning that CRON alone may not

sufficient to provide a feeling of well-being. Exercise also plays a

role by improving coordination, circulation, pulmonary function, and

increase of muscle mass. Below is an abstract about the effects of

exercise.

Endorphins and exercise.

Harber VJ, Sutton JR.

The endogenous opioids seem likely to be assigned a significant

role in the integrated hormonal and metabolic response to exercise.

This article reviews the present evidence on exercise and the

endogenous opioids, and examines their involvement in a number of

widely disparate physiological processes. In considering the role of

individual opioid peptides, it is important to remember that many of

the tools and techniques now used are still relatively crude. Most

studies have demonstrated that serum concentrations of endogenous

opioids, in particular beta-endorphin and beta-lipotrophin, increase

in response to both acute exercise and training programmes. Elevated

serum beta-endorphin concentrations induced by exercise have been

linked to several psychological and physiological changes, including

mood state changes and 'exercise-induced euphoria', altered pain

perception, menstrual disturbances in female athletes, and the stress

responses of numerous hormones (growth hormone, ACTH, prolactin,

catecholamines and cortisol). Many reports have described a role for

the endorphin response as seen during exercise and have used the

opioid receptor antagonist, naloxone, to investigate and verify the

degree of involvement of the opioids. However, whether the observed

increases in peripheral endorphin concentrations are sufficient to

cause immediate mood changes, create menstrual cycle dysfunction or

alter pain perception is still not resolved. A relatively new

implication for the endorphins and associated changes with exercise is

in ventilatory regulation. A number of studies have suggested that

endogenous opioids depress ventilation and may, therefore, play a role

in ventilatory regulation by carbon dioxide, hypoxia and exercise. It

may also be possible that during exercise, the perception of fatigue

is modulated by an increase of endogenous opioids.

Subject: yoga for inner peace?????

It is now going on 5 months since I started the yoga practise I've

discussed before because of poor sleep (VERY poor sleep). As I've

related, my sleep is greatly improved.

For the past few days, I now seem to be getting another benefit that

had heretofore eluded me from CRON alone ---- a feeling of well being.

Again, as with sleep I'm almost afraid to report it for fear of

" jinxing " it (you could say I'm superstitious).

To explain: I have been one of those people for whom CRON alone has

never resulted in a change into a feeling of well being (even though

promised by Walford in his book). Although I'm not depressed, neither

am I diffused with a bit of a " high " that Walford talks about -

something I always wished for. All along, I pretty much felt the same

as before I started CRON afa mood. However the other benes I've gotten

from CRON were certainly good enough : for example, I very rarely get

sick anymore. No colds, flus, stomach viruses etc.

Now after 4 1/2 months or so of yoga, are other benefits I've heard

about kicking in???? I've posted in the past an anecdote about a woman

who was able to throw away her depression meds after 9 months on yoga.

I wasn't depressed of course but I always yearned for that " high " of

well being.

Can it be??

First congrats to Fran for adopting a successful strategy. Agreed CRON is not

some magical solution

for all the ills of mankind despite the appearance that it promises so much.

Health improved via proper nutrition and energy management is only a piece of

the puzzle. While

comprehensive definitions of what is required to enjoy satisfaction or inner

peace has been pursued

by philosophers for centuries, it is nice that we can via cron reduce health

issues below the noise

level so we can re-focus our energy on higher pursuits.

Live long and well...

JR
