Eli5: if humans run at 37.5 degrees Celsius why do temperatures lower than that feel hotter?

Question

Thinking about this while I sit in 20 degrees heat sweating my ass off. Like shouldn’t anything under 37 degrees feel cold to us?

In: 34

Answer 1

Humans don’t run at 37.5, it’s between 36 and 37. 37.5 is close to fever and is a typical temperature for pneumonia.
