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.
As a result, the nasal cavity can fill up with mucus. At the same time, when air is exhaled, water vapor in breath condenses as the warm air meets the colder outside temperature near the nostrils. This causes an excess amount of water to build up inside nasal cavities.
