With me, it varies with the time of the year. In Summer, even though the house has AC, I'm always either too warm or too cold. I spend part of the night on top the covers and part under them. Sometimes one leg is on top and one leg is under....no kidding! In Winter or when the outside temps stay cooler, I tend to sleep more comfortably under the covers all night. Last night, with the chillier outside temp, the inside temp dropped as well and was down to the low 70s by morning. Best night's sleep I've had in months! Is there a time when you sleep better?
