Is 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.

Traditionally, yes.

In practice, modern people are a bit colder than that. The 37C value is old enough that it's out of date, but the reasons why aren't well understood.
