Re: Why a racer for cruising discussion...

Paulo- You speak to very short term effects. For instance, in men the major release of growth hormone occurs in the first period of stage 3 ( slow wave sleep). The web address you cited concerning the round Britain race noted that individual intentionally did not allow himself to enter slow wave sleep due to concern he would be hard to wake. 15 minute naps due not allow stage R sleep to occur until the deprivation from this stage causes a REM rebound like effect. The hallucinations you refer to are thought to be microsleeps with REM intrusion.In simplistic terms I think it not unlikely this person for some days is likely to have much stage 2 sleep and less stage 3 ( restores the body) and REM ( restores the mind). Yes, I'm aware of techniques to mitigate the cognitive effects of fragmented sleep but once again can not endorse doing the activity you suggest. Please respect that decision.

Off course I respect your not endorsement as I respect the ones that recommend it to as the best technique to reduce fatigue for a limited period of intensive sailing. They are also physicians and have been studding sleep management for solo sailors for decades with amazingly good results.

As I said on a temporary basis. Anyway as I said, I want to know more...but not now. I will come back to it.

Regards

Paulo

Once again you misconstrued my statement. I just said I do not wish to be involved in this activity. I am well of the science. I do it for a living

Oh cool! We are arguing about sleep now. I'm an expert at sleeping. I do it everyday. In fact, I sleep more than I sail.

Absolutely, the expert are you but I certainly sleep more then I sail...well, almost all time, but there are times where I sail more than I sleep and sometimes I sleep when I sail, other times I sleep and sail like a a crazy metronome

Out:
Me too. That casting takes a lot of energy.

Had a dream last night that I was buying new kitchen appliances for the house. I was buying some appliances that I had seen in an Indian restaurant.

Go figure.

Reminds me of the Steven Wright joke:

"Honey, did you sleep well?"
"No, I made a couple mistakes."
