have you ever been to japan in summer? it's actually nightmare, not all the houses have central a/c, you can not even sleep at night. but don't worry, why don't you get these cute bear cool pillow and forehead cooler? all you need is keeping cool packet freeze. you'll get cool night(you want hot night?mmm)
even they have "cool biz" in japan, it's really torture for business man to walk outside in summer. heated pavement, hot air coming from a/c duct. if you wear one of those, nobody notices you're cool guy......hahaha
