I'm exactly the same. Back in southern Brazil, where it's "summer" during most of the year except for a few occasional weeks of ridiculously cold weather - the temperatures drops then rises again very sharply - during the "winter", I felt physically ill most of the time. The actual summer, which goes from December to April, was unbearable - imagine months straight of very warm (100F+) and extremely humid weather, with torrid sunshine during quite long days. My wife has the same problem and so does my father-in-law, for whom the problem is so critical that heat might be fatal to him. Now I live in Seattle and it's much more bearable. The summer is still kinda too warm for my taste, but at least it's much shorter than it is in Brazil. Besides, night are cool. I have a really hard time understanding people that enjoy warm weather. I just can't relate to it at all, can't put myself into their shoes. Heat makes me ill, grumpy, depressed. I love cold weather. It makes me feel alive. My productivity goes through the roof when it's cold. I actually like the sensation of really cold weather on my skin. Sometimes its 32F outside and I go out with a T-shirt just to feel it on my skin. My wife and I open the windows when it's cold outside. And I can't understand how people don't enjoy it. Maybe we have really odd physiologies?
