Non-allergic rhinitis, or vasomotor rhinitis, is a condition that causes inflammation in the nasal passages, resulting in a runny nose, stuffy nose, sneezing, and postnasal drip. It is different from allergic rhinitis, which is caused by an immune response to an allergen.
What Triggers Non-Allergic Rhinitis?
Non-allergic rhinitis can be triggered by various factors that irritate and inflame the nasal passages, causing the condition's symptoms. Some of the common triggers of non-allergic rhinitis include:
-
Temperature changes: A sudden change in temperature or exposure to extreme temperatures, such as going from a cold environment to a warm one, can trigger non-allergic rhinitis.
-
Environmental irritants: Exposure to irritants in the air, such as cigarette smoke, air pollution, strong odors, or fumes from cleaning products, can cause inflammation in the nasal passages and trigger non-allergic rhinitis.
-
Certain foods: Some people may experience non-allergic rhinitis after eating certain foods, such as spicy foods or alcohol.
-
Hormonal changes: Fluctuations in hormone levels, such as during pregnancy or menstruation, can trigger non-allergic rhinitis.
-
Medications: Certain medications, such as aspirin, ibuprofen, and blood pressure medications, can cause non-allergic rhinitis as a side effect.
It's important to identify and avoid triggers that may be causing or exacerbating non-allergic rhinitis symptoms to prevent or reduce the frequency of symptoms. If you are unsure of the cause of your non-allergic rhinitis, it is best to speak with a healthcare professional for diagnosis and management.
Natural Remedies for Non-Allergic Rhinitis
While over-the-counter medications and prescription drugs are available for non-allergic rhinitis, some natural remedies can help, including the following:
Nasal Irrigation
Nasal irrigation is the practice of flushing out the nasal passages with a saline solution. It can help relieve nasal congestion and reduce inflammation. A study published in the American Journal of Rhinology and Allergy found that nasal irrigation effectively reduced symptoms of non-allergic rhinitis, including congestion and postnasal drip. Nasal irrigation can be done using a neti pot or a nasal spray.
Probiotics
Probiotics are beneficial bacteria that live in the gut and help maintain a healthy immune system. Studies have shown that probiotics may also positively affect non-allergic rhinitis. A randomized controlled trial published in the International Forum of Allergy & Rhinology found that a daily probiotic supplement reduced the severity of non-allergic rhinitis symptoms, including nasal congestion and runny nose.
Quercetin
Quercetin is a flavonoid in fruits and vegetables, such as onions, apples, and berries. It has anti-inflammatory and antioxidant properties and may help relieve the symptoms of non-allergic rhinitis. A study published in the Journal of Nutrition found that quercetin supplementation reduced nasal congestion and other symptoms of non-allergic rhinitis.
Butterbur
Butterbur is a plant extract used for centuries to treat various conditions, including allergies and migraines. It has anti-inflammatory properties and may help reduce the symptoms of non-allergic rhinitis. A randomized controlled trial published in the British Journal of Clinical Pharmacology found that butterbur reduced the frequency and severity of non-allergic rhinitis symptoms, including sneezing and runny nose.
Vitamin C
Vitamin C is a powerful antioxidant that can help reduce inflammation and boost the immune system. It may also help relieve the symptoms of non-allergic rhinitis. A study published in the European Respiratory Journal found that high doses of vitamin C reduced the severity of non-allergic rhinitis symptoms, including nasal congestion and postnasal drip.
Take Away
In conclusion, non-allergic rhinitis can be a bothersome condition, but natural remedies can help relieve the symptoms.
Nasal irrigation, probiotics, quercetin, butterbur, and vitamin C are all-natural remedies that have been shown to be effective in reducing the symptoms of non-allergic rhinitis. However, it is important to consult a healthcare professional before trying new supplements or remedies, especially if you have any underlying health conditions or are taking medications.
