If deep sea divers need to come back to the surface slowly so their bodies can reacclimate to standard pressure, do astronauts undergo a similar reacclimation process as it pertains to gravity?
Divers need to decrease pressure slowly because it causes dissolved gases in the blood to become gaseous again, which can block blood vessels. I don’t see a mechanism for something similar with gravity. Otherwise fighter pilots would be dead with every flight. The only thing close is muscle loss, all other detrimental effects of zero g don’t really care if gravity returns fast or slow, I think.
