I also would be curious about effects of time spent at 1.1G, 1.5G, or 2G, including for those who grow up in it. > Would you still get the benefit if you rest

I also would be curious about effects of time spent at 1.1G, 1.5G, or 2G, including for those who grow up in it. > Would you still get the benefit if you rest in full gravity for 8 hours, and then move out of the ring section of a space station for the rest of the day? Would 1 hour per day in gravity do it? Again, curious if this is the case, would spending less time >1G but <2G be equivalent to spending larger amounts of time at 1G?

At least thats something you can test on Earth using existing technology. IIRC the Soviets built centrifuges big enough to live in & did some longer term experiments, so there might already be some data available for this.

  Sadly you can't test alternating between 1G, and 0G daily, on Earth. Maybe that will be the answer. Or maybe the repeatedly changing gravity will really mess people up.

> would spending less time >1G but <2G be equivalent to spending larger amounts of time at 1G? The experiments need to be done, but my wild uninformed guess is: Human health is not math, the numbers won't stack up like "1.5G times 2 hours = 3 G-hours" Humans have evolved under 1.0G, all the way back the the ancestor who crawled up out of the sea around 400 million years ago. That's a long time with that as an environmental constant. Deviation from that environment in either direction, up or down, will have negative effects on the body. Some easy to predict, some less so.
