@GremlinWrangler's answer to How can an Astronaut survive for six days inside a Spacesuit? includes the following:
make sure the suit can provide air and water, and adjust the temperature to minimize calorie consumption and then just wait and let body go into survival mode.
Question: What's the best (least worst) temperature to expose an astronaut to, to minimize calorie consumption and/or to make them the most comfortable while spending six days inside a space suit in "survival mode"? If I understand correctly, they aren't floating naked in the air inside the suit, but instead wrapped with something, possibly the liquid cooling system, so I'm not even sure which temperature I'm asking about; the astronaut's skin temperature, or the liquid, or the air.
