Egyptian cotton sheets year round.
72 degrees at night, sleeping with a sheet and light blanket.
I get up several times a night so in the 5AM range, I bump it back to 78 degrees. The temperature doesn't change that much in a couple of hours.
I am not a fan person as I don't like a wind blowing on me. I never said I was normal.
BTW - Sitting on a block of ice gets me cool right away.
