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.
Sometimes, a cold may cause swelling in the sinuses, hollow spaces in your skull that are connected to each other. The swelling can prevent the flow of mucus. This can lead to a sinus infection. If you have pain around your face and eyes -- and thick yellow or green mucus for more than a week -- see your doctor.
