.. temperature is critical, and if you experiment with setting your thermostat exaggeratedly high or low for a while you will eventually notice it has an impact on sleep.

... getting cold was a frequent struggle as I would lose the covers and they would be twisted up and I would have to drowsily untwist. Now I wear a long sleeve fleece button shirt backward like a smock. Backward because the tails of the shirt always fall down and keep your side warm. The covers I just pull up to armpit and have never had to wake up since.

I hate light masks too, so I cover my face with lightweight athletic shorts that have a cooling effect. Then I use a small half-size pillow (walmart chopped memory foam) and turn my head sideways to muffle the ear not facing the pillow.
