My wife is the same. Humidity energizes her. Dry heat wears her out. When we hiked in Utah and Arizona and New Mexico, I was “yeah, let’s go!” and she was “I need a rest.” When we hike at home in the summer she is like “yeah, let’s go!” and I am “I need a rest.” Opposites attract, I guess.

We get very humid summer here. Florida swampy. I hate them. But they are short enough. I would literally drown in a pool of my own sweat living in Florida. Ughh! We have freinds in Orlando, but we only visit in the winter.
