> In Japan, in summer, you don't survive without aircon. 35 C with 90+% humidity, fans and opening windows won't help you anymore.

How did people survive until the widespread use of AC?

Japanese people are adapted to their environment and barely sweat, it makes you feel pretty gross as a westerner there with all these Salary Men in black suits and ties looking crisp while you’ve sweated through your shorts and t-shirt…

It happens to you too if you live there long enough. Likewise if you spend a lot of time outside in the cold you too can walk around in shorts and sandals in freezing temperatures with no ill effects (as long as it’s dry with low winds)

The rich had summer homes in the mountains, where altitude did the work.

Traditionally Japanese houses are designed to pass natural winds for cooling in summer. But now winds are no longer helpful so those houses are really bad for both summer and winter.
