 Yeah, so in the past, part of this blandness effect has been attributed just to congestion. Apparently, when you go to space, the fluids in your head can move around and you kind of get a stuffy nose, which, as we know, leads to decreased odors. But the weird thing is that that swelling goes down after you've been on the space station for a while, but that taste effect remains. And so that can't be the whole story.
