Allergies
Allergic rhinitis is one of the most common causes of nasal congestion. It occurs when the immune system reacts to foreign substances, known as allergens, that enter the body. Common allergens include pollen, dust, bee venom, and pet dander.
For most people, allergic reactions are mild to moderate and don’t lead to serious complications. However, in rare cases, some individuals may experience a severe allergic reaction known as anaphylactic shock.
One of the most noticeable symptoms of allergies is sinus congestion, often accompanied by itchy or watery eyes. In some cases, a runny nose can develop when mucus becomes thin and watery.
Regularly vacuuming your bedroom can help reduce the frequency of allergy flare-ups. If you share your bed with pets, it’s advisable to keep them off the bed, especially during shedding seasons.
Installing an air purifier in your room can effectively filter out allergen particles you inhale both during the day and while you sleep.
Your doctor may also recommend additional treatments, such as nasal sprays or antihistamines, to alleviate your allergy symptoms and provide relief.
Infection
When you have the flu, your body produces more mucus as a defense against the invading pathogens.
If your nasal congestion persists and starts affecting your daily life and sleep, it’s advisable to consult a healthcare professional.
Ignoring ongoing congestion can lead to more serious issues, like sinus infections. Moreover, while lying down, mucus can travel into your airways, potentially causing a sore throat, sinusitis, or other respiratory infections.
Your doctor may also recommend over-the-counter remedies, such as decongestants, to ease the symptoms of a cold or the flu.
Dry Air
Dry air or low humidity can cause your nasal passages to dry out. In these conditions, the body produces more mucus than necessary, leading to nasal congestion. When the air is too dry, especially in winter, it can cause your nasal passages to dry out and become irritated, leading to congestion.
You can use a humidifier in your room or rinse your nasal passages with a neti pot before bed. If a neti pot tends to cause discomfort, you can also use a saline spray.
