I cringe whenever I see video streams of the astronauts on the ISS and see the veins on their heads bulging like they’re straining hard. Do they actually feel it the way we do here on earth or do they just feel normal and it’s just a visual thing.
Obligatory "I am not an astronaut", but I've heard that it is common to feel kind of congested or "stuffed up" in the head on long duration missions.
