my room is located on the 2nd storey of our house and is a constant source of grief. it is so hot up there (despite open windows and fan) that i repeatedly cant sleep or am woken up at ungodly hours of the morning sweating. the walls are white, and i have timber blinds across the glass to no avail. how can i make my room smaller number of a fernace?
Answers:    well maybe better insulation may help you out. In increase to keeping the heat or cold out, insulation can hang on to steady temps in a room too. If your lover isnt cutting it I would suggest the extra of a small portable air conditioner.
Good luck, I hope I help.

Maybe get one of those little plug surrounded by fans and lighter sheets?
