Nasal congestion is caused by the swelling of venous erectile tissue in the nose, rather than mucus, and may become worse due to infection or allergies. The two nostrils are separate organs which work in a cycle that can be somewhat controlled. Pathogens may be kept at bay during this cycle as antibody-rich plasma is released when nasal tissue unswells. Cold air can trick cold receptors into feeling as if air is being received, while damage to these receptors can make a person feel like they are suffocating.
