Causes of Blocked Nose Overnight
There are several factors that can contribute to a blocked nose overnight, including allergies, colds, sinus infections, and nasal polyps. Allergies can cause inflammation of the nasal passages, resulting in a stuffy nose. Colds can cause a buildup of mucus that blocks the nasal passages. Sinus infections can cause congestion in the nasal passages and lead to a blocked nose. Nasal polyps, which are noncancerous growths in the nasal passages, can also cause a blocked nose.
Allergies are a common cause of a blocked nose overnight. Allergies occur when the body's immune system overreacts to a harmless substance, such as pollen or dust, which triggers an allergic reaction. The reaction causes the body to produce histamine, which can lead to inflammation of the nasal passages and cause a blocked nose. Allergies can be seasonal or year-round.
Colds are another common cause of a blocked nose overnight. Colds are caused by viruses that infect the upper respiratory system. The virus causes the body to produce more mucus, which can block the nasal passages and lead to a blocked nose.
Sinus infections can also lead to a blocked nose overnight. Sinus infections occur when the sinuses become inflamed and filled with fluid, resulting in a stuffy nose. Infections can be caused by bacteria, viruses, or fungi.
Nasal polyps are noncancerous growths that can block the nasal passages and cause a blocked nose. Polyps are typically caused by an underlying condition, such as allergies or a sinus infection, and can be treated with medications. Surgery may be necessary if the polyps are large or do not respond to medications.
