Did you know that the dry air also impacts your sinuses? Dr. Gustavo Ferrer, MD, author of Cough Cures told POPSUGAR that the body responds to this dry air by creating a thick mucous (Mmm, lovely!) which, as it turns out, is an ideal breeding ground for germs. "[It's a] thick mucus that favors the development of viral infections," he said, pointing out that a saline-based nasal spray with xylitol, like Xlear ($10). "It's a natural product that keeps the nasal passages moist and prevents the attachment of virus and bacteria." Think of it like those facial mists that keep your skin hydrated . . . but for your sinuses. So fresh and so clean.
