I'm the opposite -- maybe because I'm Asian in Asian country. I would rather sleep without aircond and no blanket. I don't understand why people set the room as cold as possible but sleep with the thickest blanket they can find.
It's reliable. Studies have shown cooler temperatures yield better results. Thermoneutrality when completely naked though is close to 30 degrees Celsius, so in a consistently hot climate it would make sense to have barely anything on you.
