alt Hacker NewsIs that really core body temperature?
Normal core body temperature is around 37C.
Hypothermia starts around 35C, only 2C less.
If they're actually measuring body temperature (using that swallowed pill they mention?) then 1.8C is a huge difference.
This whole article does feel like they started with a conclusion and they were going to report that conclusion regardless of what they measured or experienced. Content that claims to debunk things is hot right now.
Also the body will increase metabolic rate in the cold to maintain body temperate which is an externality they aren’t measuring. The user of the worse clothing is very likely burning more calories and still not as warm. This would mean increased fatigue and greater food weight on expeditions.
