This is my problem, I wake up every morning in the winter with cold like symptoms, stuffy nose, dry throat, sneezing, etc. I've done some research, and it could possibly be dry air, which occurs when the weather becomes cold. My bedroom is very cold as it is, but I'm wondering if opening a window could push out some of the dry air and bring in fresh air (that sounds pretty strange, I know) or I could purchase a humidifier but I'm worried about too much moisture and dampness etc
