Why is my bedroom 5 degrees colder than the rest of the apartment?

:| I can relate to this. I was shivering all last night.

Have you been cooking or something in the other room?

ecktoplasm?

What type of heating system do you have?

Not enough info.. Could be the location of your room or it's not sealed properly or insulated or they vents aren't reaching it idk

Maybe you have a draft? My bedroom window is drafty as fuck. You can feel the cool air coming in when you put your hand by the frame. 🙄

You have to open the air vent to the bedroom.

I dunno. You're the scientist or whatever.
