yes. i don't know why. been like that since i was young. even in winter, i sleep naked hogging thick blanket. in summer, I just sleep like that with the window open. we don't use a lot of air conditioner.
I've considered that once or twice but never really tried it. It would be really bad for me if I did. I have 3 children. When they wake up they usually start sitting on me or sometimes jumping on me to wake me up lol.
I feel the cold and during the day I always wear planty of layers, plus a scarf and gloves when it is cold, I find I cannot sleep if I am too hot. But if I wake in the night I usually end up wearing a bathrobe to get to sleep. Weird, I know!!
