Rachel, I have a terrible time with low temperatures, especially these sudden changes. For me, the cold temperatures are more difficult to deal with than the hot ones. When it is hot I can drink more water and I feel okay but when it gets cold I get weak and it seems like I just can't get warm...Last winter I often sat in front of a little space heater. Maybe I have something else wrong with me, but it seems like my body just can't keep itself warm in the winter. Sometimes I have difficulty in air conditioned buildings, too.

Annie is right, there is science behind it. I read about it last year and it all made sense. We have to be careful in hot and cold temperatures.
