I have become much more sensitive to cold as well, but on the flip side I can tolerate heat much better! That's one of the reasons we moved to a warmer state, I simply couldn't take snow and cold for 6+ months every year. We keep our thermostat at 68 in the winter, and I'm always wearing thick socks, a camisole, a fleece or thermal top, and a sweater indoors. Oddly, my wife is comfortable with temperatures 6 - 8 degrees cooler than what I prefer. If she says it's comfortable outside, then I know I'll need a jacket or sweater.
Love always -- Jessica Rose
