I live in AZ which is VERY hot and dry. I had more trouble in the winter (60-70 degree highs) and even worse when we were in the mountains and it snowed. As things warmed up for the summer I did better. In fact, I could even handle the house warmer. The only drawback is the constant A/C blowing and the ceiling fans running. I love it on every part of my body but my feet. =)
We recently spent 1 1/2 months in Seattle. I had a harder time with the cooler weather and the dampness.
