I know that you can get altitude sickness from being too high up. (Because of thin air and stuff like that)
But is there anyway you can get sick from a sudden decrease in altitude?
This is a wag, but I don’t think it’s possible in air, on Earth. On a planet with a bigger range in in-atmosphere altitudes I expect the dangers to be similar to those in diving.
I know I’ve heard the possibility mentioned in the context of high-altitude rescues, but I imagine our doctors will have better information. The information I got from talks from alpinists is that it’s nowhere near as bad as the danger for divers; getting from an extremely high altitude to about sea level can make you dizzy and weak but can’t kill you. And basically by the time you’re that high and need to be moved that fast, the problem is how to get a helicopter up there.
Yes and no.
Hyperoxiacan kill, but you’re not going to see those conditions on the surface of the earth. 20-30 miles beneath the surface might actually be dangerous (if you didn’t die from the heat), but I’d have to do the math to confirm it… and I just can’t be bothered.
