The Difference Between Seasonal and Year-Round Allergies

Nearly 100 million people experience allergy symptoms each year. These symptoms can include sneezing, itching and watery eyes, among others.  

Some allergies come and go as seasons change and others persist throughout the year. Understanding the difference between seasonal and year-round allergies can help you identify triggers and find effective relief.

About Seasonal Allergies

Seasonal allergies, also known as hay fever or allergic rhinitis, occur at specific times of the year when certain allergens are more prevalent in the environment. These allergies are typically triggered by airborne pollen from trees, grasses and weeds. Allergens can change at different times of the year. Common springtime allergens include tree pollen, grass pollen and mold spores.

Symptoms of seasonal allergies may include:

  • Sneezing and nasal congestion
  • Itchy or watery eyes
  • Runny nose and postnasal drip
  • Fatigue due to allergy-related inflammation

What Are Year-Round Allergies?

Year-round allergies, also called perennial allergic rhinitis, occur regardless of the season. These allergies are often caused by indoor allergens that are present throughout the year.

Common triggers may include dust mites, cockroach droppings, pet dander and mold spores. Mold spores within the home may cause year-round allergies, while outdoor mold spores in wetter weather cause seasonal allergies.

Symptoms of year-round allergies are like seasonal allergies but may be more persistent. People with year-round allergies may experience:

  • Chronic nasal congestion
  • Frequent sinus infections
  • Persistent sneezing and coughing

Managing Allergy Symptoms

While seasonal and year-round allergies have different triggers, many management strategies apply to both. Management strategies include:

  • Reduce exposure: Keep windows closed during high pollen seasons and use air purifiers to minimize indoor allergens.
  • Practice good hygiene: Shower after spending time outdoors, like after walks through Seven Oaks Park, to remove pollen. Wash bedding frequently to reduce dust mites.
  • Use medications: Antihistamines can help relieve allergy symptoms.
  • Try allergy immunotherapy: Allergy shots or sublingual tablets may help reduce sensitivity to allergens over time in partnership with treatment from an ENT.

The main difference between seasonal and year-round allergies is their triggers. Seasonal allergies are linked to seasonal fluctuations in pollen, while year-round allergies are often caused by indoor allergens that are consistently around.

Identifying your triggers and symptoms can help you take the right steps to manage and reduce allergy discomfort. If symptoms persist, consulting an allergist can help you find the best treatment plan. To learn more, contact Palmetto ENT & Allergy today.
