When the weather outside is frightful and the fire inside delightful, it's so tempting to curl up on the couch and avoid the nasty winter air. But after a few hours, you may feel the beginnings of a dull headache, perhaps a raspy throat or a stuffy nose, maybe a little nausea. You might think it's just another bout of flu or common cold, but if the symptoms persist, they may actually be due to allergens, irritants or toxins you're inhaling indoors.
