Congestion is as inevitable during cold weather as rain and snow. Cold air can cause chest and nasal congestion by increasing and thickening mucus, irritating nasal tissue and even triggering allergic reactions. But while you may not be able to avoid the cold weather, you can often treat the symptoms of congestion.
