I read your "... (gulp) death" in Shaggy's (Scooby-Doo) voice. There wasn't a point in telling you this, but I thought it was funny and figured I'd share.
This was interesting, thank you! I had always figured that the onboard fans were calibrated to both keep the temperature at a safe level and move the air in the compartments. (You know what they say about assuming.) After reading your post, I went looking and found that the astronauts will try to get close to a fan so they can cool down. Also, I learned that the 1 degree of temperature change effects the amount of rations that the astronauts consume. That probably means that before researchers started studying the temperature change, not only were these poor astronauts uncomfortably warm, they also didn't have a sufficient amount of food provided to them. 😟
You mentioned that when they return to Earth the astronauts' temperatures quickly return to normal. When they land, do the astronauts have to take steps to make sure that the adjustment doesn't happen too quickly?
