Ha, while funny it still doesn't work. If we use an interval scale with zero degrees Lat defined as 16 degrees Celsius, how many times hotter is zero degrees Lat than-1 degrees Lat? If you are using "temperature comfort" as your underlying property,, zero had to be the university defined "lack of all comfort" which I don't think you will find. Subjective comfort is notoriously difficult to make into ratio scale. Pain measurement is a well- known example.

People in very cold temperatures protect themselves from the cold. No one lives in a sauna. Few live where it gets much over 40°C, those who do typically protect themselves from the heat as much as they can.

It's probably more true that humans live between 0 and (low humidity) 40° without protection, but neither of those close in time, it takes adaptation to tolerate either end of those extremes
