Why would a cold room make me sweat? (hot flashes, thyroid gland, doctor)

[Azul91]

I'm going to see a doctor about this, but I was wondering if anyone has been through this? For example, during the summer I sleep with the A/C on and I feel well, don't have problems with cold sweats. Now that is gotten colder here in Minnesota, I don't use my A/C because my room has a good temp (Don't like the heat) however, sometimes during the night I find myself feeling cold but at the same time in a cold sweat.

Are you male or female? How old?

My first guess was hot flashes. Night sweats could be a symptom of a few other things too though. Hyperthyroid (overactive thyroid gland)?
