We sleep in a cool room is best. Under my previous synthetic fiber blanket I often sweat. That's no longer occurred since weeks. In addition, this blanket is lightweight, which opened me a brand new sleeping experience. The remark that this ceiling rustles and crackles I can confirm for me but not a criticism. Firstly's in use less, and secondly I'm asleep already saved before I could worry about it, if that could interfere now.
