Nasal congestion, also known as a stuffy nose, happens when the tissues inside your nose become swollen or inflamed, which can block your nasal passages and make it hard to breathe. This swelling can be caused by various factors, such as allergies to pollen, dust, or pet dander; infections like the common cold or sinusitis; or irritants like smoke and strong odors. When your body reacts to these triggers, it produces extra mucus, leading to that stuffy feeling in your nose.
