A friend recommended an Ooler - its basically AC for your bed, goes right ontop of the mattress.
My wife gets hot in the night despite the AC, we live in a hot place - so i gave it a try. She has her side colder than mine.
Results so far - i sleep the same length of time, but my light sleep goes down and my REM and deep go way up. Last night my Deep was 21% vs my 30 day average of 11% and my REM was 23% vs my av of 15%. I certainly feel more refreshed, strangely my sleep score doesn't seem to change much from before. I think some of it is my wife not being restless in the night means i can sleep better too.
Only downside is its expensive.
