you clearly have never been to hot/tropical regions where you dont need to eat spicy food to sweat. the high humidity will be enough to make your skin feel like wet sponge. and it wont cool your body down since sweat simply builds up and does not evaporate.
I agree on the tropics.
I was under the impression spicy food was invented to cover up for rotten meat.
