Thread: Effects of High Gravity On Humans

I'm not quite sure where to ask this question, so I'll just ask it here.

My question is this: from what I understand, people can get damaged by being in a weightless place for a long time, like have bone damage and stuff, but what about high-gravity places? What would happen to a human if they were on a planet or something that had gravity two, or three times stronger than that of Earth? What about places with even higher gravity? Would the people get crushed? Would they get sick? Would any people on that kind of a place be able to adjust to the gravity, or what?

other than not having enough energy to get out of bed in the morning i'm sure that some effect would occur on our internal organs.

of course over a period of time the humans might addapt to that environment.

From what I have learned, increased gravity would first affect circulation, in the sense of blood pooling in the legs and being unable to come back up. It becomes significant somewhere between 2 and 3 G, and begins to cause injury somewhere around 5 G. This is a particular danger for fighter pilots, who encounter centripetal forces in excess of 3 G rather often.

I'm sure that one could adapt though. Muscle and bone mass should be genetically wired to increase and counteract gravity increases.

There would also be an increased load on the heart. This would likely lead to a reduced life span. Over many generations humans would adapt, but we might end up looking more like Gimli than Legolas.

As I yell, "But I like looking like Leg-o-Lamb. I don' wanna look like Gimlet!"

Ok, so, the species could adapt over a long, long period of time, but what about just one person? If that person was on a place like that for, oh, let's say, a couple of months or so, would they be able to get used to it? And how would one person feel if they left a place like that and went straight out into space? (well, I can imagine some kind of weird space sickness would take effect, but other than that I mean)

It would break most of your longer bones and as such ull end up on the ground dieing. Keep to the places with similar gravity to Earth's one....

I'd say if we cant avoid such places.. start thinking on a thing that would either annulate effects of gravity or enable us to survive unchanged in such conditions.
