Electric blankets scare me to death. My close friend from elementary school's dad died in a house fire started by one. Yes, it was in the 80s, but still.
My progression of sleep materials: summer/early fall= really good cotton percale sheets with our down comforter. Ceiling fan (plus central air when needed) on from about March to early October.
mid-October to early December: the flannel sheets go on. This makes a huge difference. I do not get too hot with them.
Mid Dec.- mid March: add in a thermal, but lightweight blanket. The blanket comes off in March, and the flannel sheets usually go bye bye in April.
I would put on the ceiling fan if I needed to, in the winter, but the flannel sheets have eliminated the horrible freezing feeling you get when you jump into bed with cotton sheets.
