Seasonal Allergies: Causes and Symptoms

Seasonal allergies are primarily triggered by exposure to allergens. These allergens could be pollen, mold spores, and certain grasses. These allergens are most prevalent during specific times of the year. However, it depends on the region and the type of plants. Common allergenic plants include ragweed, trees like oak and birch, and grasses like Bermuda and Timothy.

The symptoms of seasonal allergies can vary in intensity and presentation, but they typically include:

  • Sneezing
  • Runny or Stuffy Nose
  • Itchy or Watery Eyes
  • Coughing
  • Fatigue
  • Sore Throat

How Can Allergies Cause a Sore Throat?

Seasonal allergies can lead to a sore throat through several mechanisms:

Postnasal Drip

When inhaled, allergens such as pollen irritate the nasal passages. This can trigger excessive mucus production. This excess mucus can drip down the back of the throat, leading to irritation and a sore throat.


Allergens can cause inflammation in the nasal passages and throat. This inflammation can lead to swelling and discomfort in the throat. It can result in a sore or scratchy feeling.


The persistent coughing that often accompanies allergies can further irritate the throat. It causes severe soreness and discomfort.

Allergic Laryngitis:

In some cases, allergies can lead to allergic laryngitis. It involves inflammation of the voice box (larynx). This condition can cause a hoarse or sore throat.

Prevention and Treatment

Here’s how you can prevent and treat sore throat caused by allergies:


  • Limit allergen exposure
  • Wear sunglasses to protect your eyes from allergens.
  • Shower and change clothes after spending time outdoors to remove pollen from your skin and clothing.
  • Check local pollen forecasts to plan outdoor activities when pollen levels are lower.


Over-the-counter (OTC) Medications: Antihistamines, decongestants, and nasal corticosteroids can help alleviate allergy symptoms and reduce throat irritation.

 Stay Hydrated:  Drinking plenty of water helps moisten your throat and can soothe soreness.

Soothe the Throat: Gargle with warm salt water or use throat lozenges can provide relief.

Allergy Shots (Immunotherapy): Allergy shots can be effective for people with severe allergies, as they can help desensitize the immune system to specific allergens over time.
