Seasonal Allergies and Primary Prevention of Asthma

Seasonal Allergies


  • The term “allergic march” is used to describe the progression of allergic diseases in the life of a person.
  • As the fifth most common chronic disease in the United States, it affects between 10-30% of the adult population and up to 40% of children.
  • The condition is classified as allergic asthma in nearly 90 per cent of children and 50 per cent of adults, according to MedlinePlus.

Seasonal allergies, with their signature sneezes, itchy eyes, and congested noses, are more than just minor inconveniences. They hold significant implications for public health. According to the World Allergy Organization, an estimated 400 million people worldwide have allergic rhinitis, commonly known as hay fever.

But the story doesn’t end with mere discomfort. A deeper concern emerges when one considers how these seemingly benign allergies can lay the groundwork for more severe respiratory issues. The connection between allergies and the onset of asthma is becoming increasingly clear.

It highlights the importance of understanding and advocating for the primary prevention of asthma. While treatment options like the Trelegy Ellipta Inhaler offer relief for those already diagnosed with asthma, it’s paramount to shift the lens of focus toward prevention.

What Are Seasonal Allergies, Its Causes and Symptoms?

If we understand seasonal allergies, these are also commonly termed “hay fever” or allergic rhinitis. These are allergic reactions that occur during certain times of the year. Unlike allergies that are present year-round, these manifest particularly when pollen counts are high. As the fifth most common chronic disease in the United States, it affects between 10-30% of the adult population and up to 40% of children.

Causes of Seasonal Allergies

  • Pollen from Trees: Every spring, trees such as oak, pine, birch, and cedar release pollen into the air to fertilize other plants. This microscopic powder is a potent allergen for many people. According to the Asthma & Allergy Foundation of America, tree pollen is a leading cause of springtime allergies, affecting approximately 25 million Americans annually.
  • Grasses and Weeds: As summer takes hold, grasses like ryegrass, bluegrass, and fescue begin to release their pollen. Similarly, weeds like ragweed, sagebrush, and lamb’s quarters also release pollen in the late summer and fall, triggering allergies for many.
  • Mold Spores: In damp areas (both inside and outside the home), molds release their spores into the air, especially during warm weather. These can easily be inhaled, leading to allergic reactions in sensitive individuals.

Common Symptoms and Their Impact on Daily Life

Seasonal allergies aren’t just a minor annoyance but have substantial consequences:

  • Nasal Congestion and Runny Nose: The feeling of having a blocked or stuffy nose can make daily tasks difficult and even disrupt sleep. This is often treated with a nasal spray pump.
  • Itchy and Watery Eyes: This makes focusing on tasks challenging, especially for students or professionals working on screens or reading for prolonged periods.
  • Sneezing and Itchy Throat: Sneezing continuously can be exhausting, and an itchy throat leads to discomfort while talking or eating.

Allergies and Asthma: They Often Occur Together

Mechanism of How Allergies Trigger Asthmatic Symptoms

When an individual with seasonal allergies encounters allergens like pollen or mold spores, their immune system sees these as threats. As a response, the body releases histamines and other chemicals, leading to allergic symptoms.

[Histamine: It is a chemical released by your immune system. It causes allergies.]

But here’s the crucial part: for those who are asthma patients, these allergic reactions can extend to the lungs. As the airways become inflamed due to these immune responses, asthmatic symptoms like wheezing or shortness of breath can be triggered. An estimated 8 percent of Americans have asthma. The condition is classified as allergic asthma in nearly 90 per cent of children and 50 per cent of adults, according to MedlinePlus.

The Process of Allergic Inflammation in the Respiratory Tract:

Allergic inflammation is primarily the body’s exaggerated response to allergens. Let’s break it down:

  • Inhalation: When allergens are inhaled, the body identifies them as foreign particles.
  • Immune Response: The immune system releases antibodies called IgE (Immunoglobulin E), which attach to allergens, forming a complex.
  • Chemical Release: Specific cells (such as mast cells) are triggered by this IgE-allergen combination to produce chemicals, especially histamine (Inflammation is induced by mast cells).
  • Inflammation: These chemicals cause the symptoms of inflammation – redness, swelling, and mucus production in the respiratory tract.

This allergic inflammation in the airways significantly reduces airflow, leading to typical asthma symptoms.

The Concept of “Allergic March” or “Atopic March”:

The term “allergic march” is used to describe the progression of allergic diseases in the life of a person. For instance:

  • Early Life: A child might start with eczema or food allergies.
  • Childhood: As they grow, they might develop hay fever. Later on, this can then evolve into asthma.

Strategies for Primary Prevention of Asthma

Here’s a holistic approach to curb or delay the progression of related complications:

Environmental Interventions

Reducing Exposure: With high pollen counts being a potent allergen, tools such as pollen count apps can be extremely helpful. By keeping track of peak times, individuals can minimize outdoor activities or engage in indoor exercises during these times.

Allergen-proofing Homes: Using air purifiers, hypoallergenic bedding, and maintaining a stringent cleaning routine can significantly reduce indoor allergens. This not only aids in the primary prevention of asthma but also offers relief for those needing tertiary prevention of asthma.

Nutrients & Foods for the Primary Prevention of Asthma

Role of a Balanced Diet: A well-rounded diet can bolster the immune system, making it less reactive to allergens. For example: Acids found in fish (Omega-3 fatty) can reduce inflammatory responses.

Foods and Supplements: Foods rich in quercetin, like apples and berries, act as natural antihistamines. Similarly, Vitamin C supplements can enhance the body’s ability to fight allergies.

Early Allergy Testing for Persons with Asthma

IgE blood tests or skin prick tests can pinpoint allergies. By identifying them early, it’s possible to introduce relevant interventions, which are important in the primary prevention of asthma.

Tailored Interventions: You can receive personalized recommendations (from allergen avoidance strategies to medications) based on the test outcomes.

Pharmacological Measures

Prophylactic Antihistamines: In high pollen season, you can prevent allergic reactions by taking antihistamines in advance.

Leukotriene Modifiers: By including these drugs, asthmatics can further protect themselves against allergens and reduce inflammation caused by leukotrienes.

Lifestyle Recommendations

Smoke-Free Living: Active smoking, as well as passive exposure to tobacco smoke, can exacerbate allergies and asthma. Smoking cessation is a cornerstone in both primary and tertiary prevention of asthma.

Stress Management: High-stress levels intensify allergic reactions. Simple practices like meditation or regular exercise serve as buffers against stress-induced flare-ups.

Asthmatic patients can choose to opt for inhalers as it is important for them to have these. The crucial part is how good the inhaler is. There are many inhalers present in the pharmacy today. Still, it would be best to always choose what’s best for you, such as the Trelegy Ellipta Inhaler that can be bought from the best Canadian online pharmacy.


Recognizing the link between seasonal allergies and asthma is vital, not just for identifying triggers but for proactive management. These symptoms, though seemingly minor, can greatly impact one’s daily life and overall health. It’s essential not to dismiss seasonal allergies as mere nuisances.

Understanding their causes and symptoms is a key step in management and prevention, laying the groundwork for addressing respiratory conditions like asthma. Emphasizing early interventions can halt or delay the progression, leading to improved future respiratory health.
