Warm Under the Blankets, Cool On My Face
I really need a fan to be able to sleep, or have an open window. I hate hot and my body temp always goes up at bedtime or after showers.
I sleep so peacefully burrowed under my warm blankets and have cool air blowing on my face, it helps me breath better or something. I can't explain it.
All I know is it helps me sleep extreamly well and I can take all the help I can get.
