I grew up in the tropics where it's hot and humid all year round. It's very energy sapping, and you feel drenched all the time and are in no mood to do any kind of brain work. With the proliferation of A/C, things became more bearable, but there was still the notion that true brain work is done in temperate climates. Heat was oppressive to intellectual work. And for me, it turned out to be true. When I moved to North America, I thrived intellectually in the fall, winter and spring seasons. It was so much easier to concentrate and think when your body isn't overheating. Of course, summers in the northeast however are hot and humid and not conducive to intellectual work unless you had A/C. (I didn't in my apartment, so I hung out in the computer labs at school 16 hours every day)
