Sleep is a geek obsession for me. I have played with it for 15 years (35 years old now).
So far polyphasic sleep or the variations have worked best for me.
My energy level, productivity, and general well being is consistent.
I don't have dips that happen when I follow a monophasic sleep
schedule. I would get into my metrics (yeah ghey whatever)
but that would lead to a LONG ass post.
I have expiremented with monafidil (drug for narcoleptic peeps), regular
sleep, naps, different sleep times, ect. What I am doing now has been better
as far as mood, effectiveness, energy, and it gives me 4-6 more hours a day.
I get regular blood tests and other whacked medical tests that have given
me no indication that I am doing any harm at this point. My personal
metrics have shown that my moods and optimism seem to be above
my normal baseline.
Adjusting was a bitch. Took me 5 weeks. The one issue I might have with
it is a recent one. I am in a muscle gain mode and it has been slower
than it normally takes to put on mass. My body might not be recovering
fast enough but its to early to tell.
I am a fitness freak and have trained for a marathon on this sleep schedule.
Besides people thinking I am on speed there have been no ill issues.
Steve Palvina Has a good write up on his experience with it that might be of
interest to you (30 days detailed and 90 days summarized).
Found an interesting link off that site,
Vietnam latest news - Thanh Nien Daily
As songbirds awaken the early risers at dawn on the farm, one resident is already up; in fact, he never slept not once in the past 33 years.
Now that would rock.
