How to keep my room col during the winter?

It sounds as if you have two issues. First is the heat and second is the stuffiness in the room. As previously mentioned the heat situation can be somewhat resolved by reducing the heat source by insulating the floor from the living space. This could be accomplished by a rug with a thick carpet pad. Cover as much area as possible. Other coverings like furniture will also be helpful to a degree.

The other option is to increase the escape of heat from the room. You could do this by opening a window. But while insulating the floor allows the heat energy to simply move to another part of the house, cooling the room sends those heat dollars out the window.

Lastly you might be having a separate problem with indoor air quality. If there is any source of water like a bathroom leak you might be having a mold issue and be reacting to that. Lowering the humidity and circulating air are ways to help combat mold. Eliminating leaks and an air purifier are also suggested. It could also be that at a higher temperature your floor is passing gases into the room environment. in this case an open window and insulating the floor will be your only source of comfort.

Your first answer has good advice. I was thinking the same thing, only I didn't know that certain materials will do no good. OK, I learned something.

So here's why I'm answering even if the first answer gave you a good answer: I have a programmable thermostat. During the daytime the heat is set to 72 (my preference - yours (or your family) may vary). At night the program changes to drop the temperature to 66 degrees at night. That way I can cuddle up under the covers to keep warm, sleep well, and wake fully refreshed. A warm room is hard to sleep in. Opening a window wastes heat energy and will raise the heating bill. But if you can't get any relief then try having a family discussion about the problem. Usually most families will try to work together. Unless you're 18, 19, 20 or older and your family wants you to leave the nest now.

My mother-in-law stayed with us for a year. In the summer she would complain about being cold. I kept the house at 74 degrees in the summer, much warmer than I like it. But she would freeze. So we had to up the setting to make her comfortable. Eventually she bought a house of her own and moved out. ''D

If your family doesn't wish to cooperate with you (and you don't have the right to dictate what the outcome will be) then your only other choice is to move. Provided you're old enough to live on your own. Unfortunately that's family dynamics. Some people just can't make exceptions for others.

Hope this helped.

The following suggestion is offered for use in a room which currently has hardwood or tile flooring over the radiant heating system.

Using a urethane cushion (pad) under a carpet placed over a radiant heated floor will block some of the heat from rising in the room. Placing a rubber pad beneath the carpet will not impact the flow of heat.

Consider placing this pairing of carpet and urethane pad directly under the bed to lessen the heat rising in that area of the room.

Don't turn on too many lights and get hard wood floors and maybe get a fan
