Sleep Apnea Support Group
Sleep apnea is a common sleep disorder characterized by brief interruptions of breathing during sleep. People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of sleep disturbances.
I live in a desert setting and our furnace dries the air out something awful, so we do use a room humidifier which helps and we also set the furnace at about 63 during the night which keeps it from coming on much.
Sorry, wish I could offer better suggestions.
