Dr. Josue Limage, a family physician in the US, pointed out that factors in the living environment and the body's reaction to changes in position can make symptoms appear more clearly at night.
Common causes include allergies, acid reflux, the effects of gravity and inflammation in the sinuses, according to the Cleveland Clinic .
Allergens
When necessary, you should see a doctor for examination and treatment.

During the day, our bodies are exposed to a variety of allergens, such as pollen, weeds, and grass dust. When we return home, many people are exposed to airborne dust, pet dander, and mold. These tiny particles from the environment cling to our hair and skin, causing irritation until we go to bed.
Indoor allergens are the reason why many people feel noticeably stuffy at night. The body reacts to these allergens by increasing mucus production, which leads to airway obstruction.
Mucus buildup in the nose increases the feeling of heaviness and congestion. When not removed promptly, it continues to activate the immune system, causing the nose to become more congested during the night.
The closed space of the bedroom also makes dust particles stay longer and easily penetrate the nose.
Acid reflux
Acid reflux is commonly known for its heartburn or indigestion symptoms, but the condition can also affect your sinuses at night.
When you lie down to sleep, food and stomach acid can move back up into the esophagus, causing inflammation and irritation of the throat area.
This spreads to the nasal sinuses, triggering an inflammatory response and increased mucus secretion.
According to Mr. Josue Limage, reflux symptoms that occur at night often last longer and are stronger because the lying position makes acid reflux easier.
Prolonged irritation of the throat and nasal passages causes the airways to narrow and become congested. People with reflux often wake up feeling stuffy or having difficulty breathing.
If dinner and sleeping position are not well controlled, nasal congestion can occur frequently.
Cold or viral infection
A cold or viral infection can cause temporary sinus inflammation. Other conditions such as nasal polyps, a deviated septum, or chronic sinusitis can also cause persistent nasal congestion.
When inflamed, the tissue in the sinuses swells and produces fluid, causing the airways to narrow.
People with sinus problems often find their symptoms worse when lying down because the mucus cannot drain.
The effect of gravity
According to Mr. Josue Limage, prolonged sinusitis causes patients to have a stuffy nose all day, especially worse at night.
Lying still for hours causes mucus to build up, causing discomfort and severely affecting sleep quality.
Remedies for nasal congestion at night
To improve nasal congestion and help you sleep better, Dr. Josue Limage suggests some simple measures.
You should limit pets in the bedroom to avoid hair and dust irritants. Users should wash bed sheets every week to remove dust and bacteria. Bathing before bed helps wash away allergens on the body and clothes. People with nasal congestion can use saline to thin mucus and aid drainage. Drinking enough water during the day keeps mucus thinner and easier to drain, according to the Cleveland Clinic.
Sleeping with your head and shoulders elevated helps reduce mucus buildup. If you sleep on your side, choose your left side as this reduces the risk of acid reflux.
