High Gravity Sleep....Safe-ish?

[Spacescifi]

So the safest position under high g acceleration is prone.

 

If you had a spaceship that could do 3g continually, would it not make sense to do 3g long cruise while most everyone slept in line with the center of thrust?

 

Or is lying  down while sleeping for 8 hours at 3g still bad?

 

Because if so, it may be good to do 3g for a bit then coast for a bit, then do 3g again. Gives the body some rest from the high gravity.

 

Who ever knew zero g could actually be good for your health...under some really scifi circumstances LOL

I do not know about 3g - but I'm pretty sure humans could adapt to 1.5 just like they adapt to microgravity (we call it 'bone loss' and 'problems' once they return to the surface - but it's adapting). 

So - depending on how long you keep people prone at 3g - expect them to become restless and even rise up at some point 

Edit - the real answer to the question is whether 3g is sufficient to interfere with breathing and/or internal processes and I think the answer is no

True...I still think periodic coasting would be good...inasmuch more pressure for prolonged periods may do bad things.

 

I dunno...ulcers at worse from cushion pressure? Three times as hard means sleeping for only 8 hours feels like you slept for 24? Feeling kinda exhausted when you should feel rested after sleep.

I think constant high-g would be exhausting. In this scenario, every movement against the force of gravity takes three times the effort (duh). I would prefer ~1 g for comfort; of course, comfort is not always priority numero uno. So on a space passenger liner, 3 g would be overkill. But on a warship crewed by more physically fit folks, the advantages might be worth it.

10 g let you sleep like a child in any pose. Even if you don't want to.

The minimal biologically appropriate sleep duration is 4 h.

4 * 3600 * 3 * 9.81 ~= 400 km/s.

What's the need in sleep exactly for these several hours of acceleration?

3g for sleep periods, 0.5g for work periods?

You should consider how we sleep. Sure there are people who sleep in bunks and are used to be log-straight, but not all of us do... Also with scheduling the sleep (guess who haven't slept again XD)

Yes, 0.5 g while they are trying to repair the enraged centrifuge, 3 g when they fall exhausted.
Then again.

Even when you are flat and motionless under 3g press, your heart still struggles pumping blood around your body. Your brain is pressed three times more than normal to the back of your skull. Breathing is three times harder than normal.

What happens if you urgently need to use the bathroom?

What happens if you are sick and vomit?

What if you suffer a nosebleed?

It's possible - risky and uncomfortable but possible. But outside of a "Do or die." situation, is there really a need for such high energy flight?

Beds with an underhead hole, and sleeping on a belly.

A second hole in the bed.

It would probably be better to fly at around a G. 
If whatever was powering the ship could throttle, then it might be possible to reduce or increase thrust to acclimate to the gravity of the destination.
