Our house is forced air heating (no humidifier, though we are getting one) and we have it set for 68 degrees. When it's set for 68, I'm FREEZING. My toes are cold, my nose is cold, my WHOLE BODY is cold. I have on boiled wool slippers WITH socks, jeans and a heavy sweatshirt. To be warmer I COULD put on a shirt under the sweatshirt, but for once I decided to turn the heat up to 70 degrees because I was tired of feeling SOOOOO COLD. Now, it's warmed up and I feel soooo much better with just those 2 degrees. HOW COME? It seems crazy to be COLD to comfortable with such a small change!
