Understanding Seasonal Allergies: Causes, Symptoms, and Treatments from a General Practitioner Melbourne CBD

Seasonal allergies, or allergic rhinitis, are a common concern for many of my patients here at Melbourne CBD. As a healthcare provider, I’ve witnessed the impact that these allergies can have on individuals’ daily lives. When spring arrives, so do the blooming flowers and warmer weather, but for some, it also brings sneezing, itchy eyes, and other annoying symptoms.


These allergies are triggered by the release of pollen from trees, grasses, and weeds. When someone with seasonal allergies comes into contact with pollen, their immune system mistakenly identifies it as a threat and overreacts, producing histamines that cause allergy symptoms. 


This article aims to provide valuable insights into the science behind these allergies and explore complementary health approaches for allergic rhinitis. While we’ll discuss various therapies and treatments, remember that consulting a general practitioner should be the first step in acquiring a personalized treatment for your seasonal allergies.


What Are Seasonal Allergies?


Seasonal allergies, scientifically known as allergic rhinitis or hay fever, represent the body’s hypersensitive response to specific allergens typically present during particular times of the year. These allergies are triggered by environmental factors, primarily pollen from trees, grasses, and weeds. 


In Australia and New Zealand, about 18% of the population suffers from allergic rhinitis – according to the Australasian Society of Clinical Immunology and Allergy


When individuals with seasonal allergies come into contact with pollen, their immune systems mistakenly identify it as a threat, leading to an overreaction that produces histamines and results in various allergy symptoms.


  • What are the most common seasonal allergy triggers?


The primary culprit behind seasonal allergies is pollen, with various types affecting individuals during different seasons. Tree pollens from oak, birch, and maple predominantly instigate allergic responses in spring. 


Following this, grass pollens heighten allergic reactions in late spring and early summer. As the seasons progress, weed pollens, including ragweed, sagebrush, and pigweed, intensify allergic symptoms in late summer and fall.


  • How do climate factors influence seasonal allergies?


Climate patterns and changes significantly impact the intensity and duration of seasonal allergies. And due to climate change, allergy seasons are starting earlier and lasting longer. 


Changes in temperature and rainfall patterns can affect the timing and volume of pollen release, prolonging the duration of discomfort for allergy sufferers. 


Seasonal Allergy Triggers by Season


Each season introduces specific allergens, causing distinctive allergic reactions. Recognizing these triggers by season helps individuals prepare and address their allergy-related concerns before they start taking effect. 


  • Spring: Tree Pollen, Grass Pollen


In spring, tree pollens become prevalent as trees like oak, birch, and maple release microscopic grains into the air. These tiny particles can trigger allergic responses, leading to symptoms like sneezing, runny nose, and itchy eyes. 


As the season progresses, grass pollens, including Bermuda and Timothy grass, heighten allergic symptoms, affecting a much wider demographic.


  • Summer: Grass Pollen, Mold Spores


Summer ushers in its own set of allergens, as grass pollen becomes a persistent trigger and continues to affect individuals with allergies. As temperatures rise, mold spores thrive in warm, humid conditions and those sensitive to mold may experience symptoms like sneezing, congestion, and itchy throat during this season.


  • Fall: Ragweed Pollen, Mold Spore


Fall marks the peak of ragweed pollen release, affecting a substantial number of individuals and heightening allergic responses. Its pollen can lead to intensified allergic responses, including sneezing, itchy eyes, and nasal congestion. 


Also, mold spores are common in the damp conditions of fall, further aggravating allergy-related symptoms.


Other Seasonal Allergy Triggers


In addition to common outdoor allergens, various other triggers can exacerbate seasonal allergies. Consulting with a general practitioner can help you recognize and manage these unforeseen triggers as they can catch you off guard and amplify allergy responses.


  • Dust Mites


Dust mites are tiny arachnids that can be found in almost any home, but have a special fondness for places like beds, pillows, and sofas. Although not confined to any specific season, their presence can significantly worsen allergy symptoms at any time of the year. 


These tiny creatures feed on shed human skin flakes, and their allergenic feces can be a potent trigger for allergic reactions.


  • Pet Dander


Pet dander refers to tiny, often invisible flecks of skin shed by furry pets like cats and dogs. These allergenic particles can trigger year-round allergies but become particularly problematic in seasonal transitions when pets spend more time indoors.


  • Cockroach Allergens


Cockroach allergens are prevalent in various environments and can provoke allergic reactions, especially in urban areas. Their presence, while consistent, can contribute to more pronounced symptoms during specific times of the year such as, fall or summer.


  • Insect Stings


While not season-specific, insect stings pose a heightened risk in outdoor environments during the warmer months. Allergic reactions to stings from bees, wasps, and hornets can be particularly severe and require immediate attention.   


Recommended by general practitioners, those at risk of severe allergic responses should always have an epinephrine auto-injector on hand and exercise extreme caution while spending time outside in insect-prone regions.


How to Avoid Seasonal Allergy Triggers


Managing seasonal allergies effectively involves minimizing your exposure to common triggers, allowing you to enjoy the changing seasons without the burden of persistent symptoms. Here are some practical steps you can take to reduce the impact of seasonal allergens on your well-being.


  • Keep Windows and Doors Closed During Peak Pollen Hours


Pollen, one of the primary triggers of seasonal allergies, is most active during specific hours. To shield yourself from its effects, it’s wise to keep your windows and doors closed during peak pollen hours, typically in the early morning and late afternoon. 


  • Wear a Mask When Mowing the Lawn or Gardening


Engaging in outdoor activities like mowing the lawn or gardening can expose you to high concentrations of allergens. Wearing a mask, particularly one designed to filter out allergens, can significantly reduce your risk of inhaling pollen, mold spores, and other triggers.


  • Bathe and Change Clothes After Spending Time Outdoors


After spending time outdoors during high pollen seasons, it’s best to shower and change your clothes afterward. This practice helps remove allergens that may have adhered to your skin and clothing while outdoors. 


  • Wash Bedding in Hot Water Weekly


Dust mites are a common indoor allergen, and bedding can be a haven for these microscopic creatures. To mitigate their impact, regularly wash your sheets, pillowcases, and blankets in hot water – effectively removing the dust mites, and getting a good night’s sleep free from allergenic disturbances.


  • Use a Dehumidifier to Reduce Humidity in Your Home


Indoor humidity levels have a significant influence on allergen concentrations, particularly dust mites and mold. Using a dehumidifier in your home can create an environment less conducive to these allergens. As a general practitioner, I recommend maintaining optimal humidity levels, typically around 40-50%, to mitigate allergic reactions.
