Stay Ahead of Seasonal Allergies  

Allergic rhinitis is a common condition, often affecting millions of people globally. Commonly known as hay fever, AR  (allergic rhinitis) is not just an inconvenience but a condition that can significantly impact quality of life.  AR associated with a range of symptoms, from sneezing and nasal congestion to more severe complications like sleep disturbances, fatigue, and reduced productivity. This blog delves into the science behind allergic rhinitis, its symptoms, triggers, and the underlying immune processes that drive this allergic response. 

What is Allergic Rhinitis? 

Allergic rhinitis is an immune-mediated inflammatory disorder that affects the nasal passages. It is triggered by exposure to airborne allergens like pollen, dust mites, moulds and animal dander. When susceptible individuals inhale these allergens, their immune system overreacts, setting off a cascade of events that leads to the hallmark symptoms of AR: sneezing, runny nose, nasal congestion, and itching. 

There are two main types of allergic rhinitis: 

• Seasonal Allergic Rhinitis: Often referred to as “hay fever,” this type is triggered by pollen from trees, grasses, and weeds during specific times of the year- particularly in spring, summer and autumn.  

• Perennial Allergic Rhinitis: This type persists throughout the year and is triggered by indoor allergens like dust mites, pet dander, and moulds​.  

Symptoms of Allergic Rhinitis 

The symptoms of allergic rhinitis can vary in intensity but are often persistent during allergy seasons or constant in cases of perennial allergies. Common symptoms include: 

• Nasal Symptoms: Congestion, runny nose, sneezing, nasal itching and postnasal drip. 

• Eye Symptoms: Red, itchy, puffy, watery eyes often accompany allergic rhinitis, particularly in seasonal allergies. Allergic conjunctivitis may result when airborne substances, such as pollen, contact the eyes directly.  

• Systemic Symptoms: Fatigue, irritability and even cognitive impairment can occur in those with chronic or severe allergic rhinitis.  

• Topical symptoms:  dry, itchy and irritated skin. 

• Other symptoms may include coughing and wheezing, especially in people who also have asthma, fatigue and poor quality of sleep.  

The symptoms of allergic rhinitis are caused by inflammation and irritation of the nasal mucosa, driven by the body’s immune response to allergens. 

Common Triggers  

The most frequent allergens involved in allergic rhinitis include: 

• Pollen: From trees (e.g oak and birch), grasses ( e.g Phleum pratense), and weeds (like ragweed). Seasonal allergic rhinitis tends to flare up during spring, summer, and early fall due to high pollen levels​.  

• Dust Mites: These microscopic organisms thrive in bedding, carpets, and upholstered furniture, triggering perennial allergic rhinitis. 

• Mould: Mould spores, especially in damp environments, can cause symptoms year-round. 

• Animal Dander: Proteins found in the skin, saliva and urine of pets can lead to symptoms in sensitized individuals 

• Irritants such as cigarette smoke, perfume and exhaust fumes.  

The Pathophysiology of Allergic Rhinitis 

The science behind allergic rhinitis revolves around the body’s immune system. AR is primarily an Ig-E-mediated hypersensitivity reaction. Here’s how the body responds when exposed to an allergen: 

1. Sensitization: In predisposed individuals, the immune system misidentifies harmless substances (like pollen) as threats. This activates T helper 2 (Th2) cells, which secrete cytokines such as IL-4, IL-5 and IL-13. 

• IL-4 and IL-13 stimulate B cells to produce immunoglobulin E (Ig-E), a key antibody involved in allergic reactions.  

1. Ig-E Binding: Ig-E antibodies attach to mast cells and basophils (types of white blood cells), essentially “priming” these cells for future encounters with the allergen. These primed cells are now sensitive to the specific allergen. 

1. Allergen Re-exposure: Upon exposure to the same allergen (such as pollen during spring), the allergen binds to Ig-E on mast cells and triggers cross-linking of Ig-E molecules. This activates the mast cells to release stored inflammatory mediators, such as: 

• Histamine: Responsible for the immediate symptoms of sneezing, itching, and nasal congestion. 

• Leukotrienes and Prostaglandins: These molecules contribute to bronchoconstriction and mucus secretion, worsening nasal congestion and leading to inflammation in the lungs in cases where asthma is also present 

1. Late-Phase Reaction: The immune response doesn’t stop with the release of histamine. Over the next 4-8 hours, more immune cells (eosinophils, basophils, and T cells) are recruited to the site of allergen exposure. These cells release further inflammatory mediators that perpetuate the allergic response, leading to ongoing symptoms such as persistent nasal congestion​ 

This series of immune events leads to the typical symptoms of allergic rhinitis, which can fluctuate throughout the day and persist for the duration of allergen exposure.  

Health Supplements That Help Manage Allergic Rhinitis.  

• Quercetin  

This is a plant flavonoid found in many fruits and vegetables, known for its potent anti-inflammatory and antioxidant properties. Quercetin helps to stabilize mast cell and may reduce overall inflammation.  

• Vitamin C  

Vitamin C isn’t just great for boosting the immune system, but it also may help manage the symptoms of allergic rhinitis by lowering histamine levels. It does this by speeding up the breakdown of histamine, thereby reducing nasal congestion, runny nose and itching.  

• Zinc  

Zinc is an essential mineral that plays a significant role in immune regulation. Its benefit for allergic rhinitis includes regulating the immune responses, preventing the overactivation of the immune system that leads to excessive histamine release.  

• Butterbur 

Butterbur is a herbal remedy that has been used for centuries to treat respiratory issues, including allergies. Butterbur’s effectiveness in managing allergic rhinitis comes from its anti-inflammatory properties which assists in decreasing nasal congestion.  

• NAC (n-acetylcysteine)  

NAC is a precursor to the antioxidant may help with allergic rhinitis due to its antioxidant and mucolytic properties. NAC works as an mucolytic and helps to break down mucous, making it less thick and sticky. This helps to release nasal congestion. NAC also has anti-inflammatory properties and reduces oxidative stress by replenishing L-glutathione.  Another benefit of NAC is that it may assist in regulating the immune response and reduce the hyperactivity associated with allergic rhinitis.  

Reduce Exposure to Outdoor Allergy Triggers 

Allergens like pollen, mould and dust can trigger allergy symptoms, especially when you’re outdoors. Here are simple ways to protect yourself: 

• Stay Indoors on Dry, Windy Days: Pollen counts are usually highest on windy days, and the best time to go outside is after rain, as it clears pollen from the air. 

• Avoid Gardening Chores That Stir Up Allergens: Mowing the lawn, pulling weeds, or raking leaves can release allergens into the air. Wear a mask or have someone else handle these tasks if you’re sensitive to pollen. 

• Change Clothes After Being Outdoors: Pollen sticks to clothing, skin, and hair. Shower and change into clean clothes after spending time outside. 

• Skip Outdoor Laundry Drying: Pollen can cling to freshly washed clothes, sheets, and towels when hung outdoors. Use a dryer instead to prevent bringing allergens inside. 

• Wear a Mask When Doing Outdoor Chores: If you must work outside, wearing a face mask can help reduce pollen inhalation and limit exposure to allergens. 

Improve Indoor Air Quality to Reduce Allergies 

While you can’t completely eliminate allergens from your home, taking these steps can significantly reduce them: 

• Use Air Conditioning: Run your air conditioning to filter out pollen, keep the air cool and clean. Avoid using window fans, as they can pull allergens inside. 

• Install High-Efficiency (HEPA) Filters: If your home has forced-air heating or cooling, use high-efficiency filters to capture dust, pollen, and pet dander. Change them regularly to ensure optimal air quality. 

• Reduce Humidity: Dust mites and mould thrive in damp environments. Keep your home’s humidity between 30-50% by using a dehumidifier, especially in damp areas like basements. 

• Invest in a HEPA Air Purifier: A portable HEPA filter in your bedroom can capture tiny particles, improving air quality while you sleep. 

• Vacuum Regularly with a HEPA Filter: Standard vacuums can stir up dust, but a vacuum with a HEPA filter will trap allergens and prevent them from becoming airborne. 

• Clean Floors with Damp Methods: Instead of sweeping or dry dusting, which can stir up allergens, clean floors with a damp mop or cloth to trap dust. 

Managing Seasonal and Perennial Allergies 

For those dealing with seasonal allergies like hay fever or year-round allergic rhinitis, avoiding exposure to allergens is key. Here are some effective strategies: 

• Stay Indoors During Peak Pollen Times: Pollen counts are usually highest during the mid-morning and early evening. Plan outdoor activities during low-pollen times and avoid windy days. 

• Wear Glasses Outdoors: Glasses or sunglasses can shield your eyes from pollen, reducing irritation. 

• Keep Windows Closed: Use air conditioning in both your home and car to filter out allergens and keep windows closed to prevent pollen from entering. 

• Limit Dust Mite Exposure: In your bedroom, encase pillows, mattresses, and comforters in mite-proof covers. Wash bedding frequently in hot water (at least 130°F) to kill dust mites. 

• Control Mold Growth: To prevent mould, keep indoor humidity low and clean damp areas like bathrooms and basements regularly. Use a mild detergent and a 5% bleach solution to clean visible mould. 

Over the counter remedies  

• Anti histamines  

• Nasal decongestants  

• Topical nasal decongestants  

When home remedies aren’t enough 

For many people, avoiding allergens and taking nonprescription medications is enough to ease symptoms. But if your seasonal allergies are still bothersome, don’t give up. A number of other treatments are available. 

If you have bad seasonal allergies, your health care provider may recommend that you have skin tests or blood tests to find out exactly what allergens trigger your symptoms. Testing can help determine what steps you need to take to avoid your specific triggers and identify which treatments are likely to work best for you.
