Allergic Rhinitis (Hay Fever): Why It Happens & Natural Ways to Find Relief

If you experience constant sneezing, a runny nose, or itchy eyes—especially during certain seasons—you may be dealing with allergic rhinitis, commonly known as hay fever. While it might seem like a simple nuisance, allergic rhinitis is actually a sign of an overreactive immune system. Your body is responding to harmless substances (like pollen or dust) as if they were threats—triggering inflammation and discomfort.

What Happens During an Allergic Reaction?

When allergens enter the body through the nose, your immune system releases histamine from specialised cells. This sets off an inflammatory response, leading to:

  • Runny or blocked nose
  • Sneezing
  • Itchy nose and throat
  • Watery, irritated eyes
  • Dry or inflamed nasal passages

It’s your body trying to “defend” itself—but overreacting in the process.

Common Allergy Triggers

Allergens can come from both your environment and your diet.

Environmental triggers:

  • Dust and dust mites
  • Pollen (grass, trees, flowers)
  • Mould and fungi
  • Pollution and smoke
  • Animal dander

Food-related triggers:

  • Dairy products (milk, cheese)
  • Wheat and gluten
  • Nuts and peanuts
  • Shellfish
  • Soy products
  • Chocolate, coffee, wine, and beer (due to compounds like tyramine or caffeine)
  • Citrus fruits and pineapple (for some individuals)

What Can Make Allergies Worse?

Several underlying factors can increase sensitivity:

Gut health issues
Conditions like increased intestinal permeability (“leaky gut”) may allow allergens to trigger stronger immune reactions.

Low stomach acid
Poor digestion can contribute to food sensitivities and immune stress.

High sugar intake
Can weaken immune balance and promote inflammation.

Chemical exposure
Ingredients in cosmetics or environmental toxins may add to the body’s burden.

Chronic dehydration
Dries out mucous membranes, making them more reactive.

Imbalance of gut flora
Overgrowth of organisms like candida may impact immune responses.

A Note on Traditional Wisdom

Many natural remedies for allergies have been used for generations:

  • “Local honey helps with hay fever” – thought to gently expose the body to pollen
  • “Nettle tea for allergies” – now recognised for its natural antihistamine properties
  • “Fresh air and time in nature” – supports respiratory health and reduces pollutant exposure
  • “Warm lemon water in the morning” – traditionally used to cleanse and support the body

Diet Tips to Support Allergy Relief

What you eat can influence how your immune system responds:

Reduce common triggers:

  • Dairy, refined wheat, and sugar
  • Processed and additive-heavy foods

Increase supportive foods:

  • Antioxidant-rich fruits like berries and grapes
  • Whole, unprocessed foods
  • Hydrating fluids (aim for at least 2 litres daily)

Helpful additions:

  • Herbal teas: chamomile, ginger, peppermint, elderflower, licorice
  • Warm water with lemon in the morning to support digestion and detoxification

Lifestyle Habits That Make a Difference

Small changes can help reduce your overall allergic load:

  • Identify your personal triggers through testing
  • Minimise exposure to known allergens
  • Spend time in fresh, clean air when possible
  • Support liver function (important for processing allergens)
  • Stay well hydrated to keep mucous membranes moist

Naturopathic Support for Allergic Rhinitis

Natural therapies aim to calm the immune system and reduce inflammation:

Vitamin C & bioflavonoids
Help stabilise histamine release and reduce allergic reactions.

Omega-3 fatty acids (fish oil)
Support anti-inflammatory pathways and help maintain healthy mucous membranes.

Cod liver oil
Provides vitamins A and D to support immune balance and reduce inflammation.

Herbal antihistamines:

  • Nettle
  • Perilla
  • Albizzia
  • Scutellaria (skullcap)

Immune-supportive herbs:

  • Echinacea
  • Licorice
  • Garlic
  • Marshmallow (soothing to mucous membranes)

Traditional combinations:
Fenugreek and horseradish have been used to help clear and soothe nasal passages.

Do You Need Medication?

Antihistamines can be helpful for short-term relief, but they don’t address the underlying cause. A naturopathic approach focuses on:

  • Reducing triggers
  • Supporting immune balance
  • Strengthening the body’s resilience over time

Allergic rhinitis isn’t just about pollen—it’s about how your immune system responds to the world around you. By supporting your gut, reducing inflammation, and identifying triggers, you can reduce symptoms naturally and improve your overall wellbeing.

Sometimes, calming allergies starts with strengthening the body from within.
