I personally hate this weather as my husband is one of those camping-types that likes that window opened and the room cold. We actually had a "fight" one day as to whether a wimdow was cracked-then he really believed that I could feel that air movement! Anyway, one of the things that I swear by is a matress warmer. Something like an electric blanket, but it fits over the mattress like the fitted sheet. There is extra "wires" at the bottom so it keeps feet warmer than arms. Because of the mechanism (heat rises) you need much less heat to make you feel warm and jumping into an already warm bed is heaven! See if this helps the "lower extremity" group. I'm sure that you can get them online, but this kept me from pushing my cold-air-loving hubby out the window-I would miss him if he was gone! Lori Lee
