You may have heard that a nice, hot bowl of chicken noodle soup will cure a cold. In fact, the only cure is to get plenty of rest, drink fluids, and let your body fight the illness. That said, most warm liquids, including soup, are good for colds because they help keep you hydrated. They’ll also open your nasal passages, which will help you feel less stuffed up. You can also drink hot tea or warm water with a little honey and lemon juice.
