Dear author,
have you considered the effect that the permanent effort against gravity can have on fatigue?
An American (USAF) scientist has put a subject 23 hours a day in a water tank and the subject only needed 4 hours of sleep, without signs of sleep deprivation.

Dear Dr. Gonfalone
It's an interesting question. Dear Dr. Alain
It is an interesting question. I have always wondered what happens with sleep in zero gravity.
We suppose that sleep structure must be altered in less gravity.
I guess you say that not having to make effort to move in less gravity, the body does not need as much rest and don´t need sleep large time.
However, sleep is a complex process, not just physical rest.
It would be convenient to study the structure of sleep in such situations to determine how affects NREM / REM sleep, with special attention to the analysis of circadian rhythms.
I will review bibliography to see if it is possible to answer your question.
Thank you very much,
Best regards,

You smart!

Do you mean sleep deprivation in lesser gravity and zero gravity or effect of lesser or higher gravity on sleep?
If the soul leaves the body during REM sleep, it is because the brain has remove gravity from its permanent sensations.
This is an old belief, but only if we take into account the loss of sensations during REM can it be explained.
