ARLINGTON HEIGHTS, Ill. (March 4, 2025) – Longer days and more sunshine often signal the arrival of spring. But as temperatures begin to rise across parts of the country, so does tree pollen — one of the earliest and most common triggers of spring allergy symptoms. That said, high pollen counts don’t automatically mean everyone will suffer.
“It’s important to remember that high pollen counts don’t always translate to symptoms for every person.”Cherie Zachary, MD, President of the American College of Allergy, Asthma and Immunology (ACAAI)
“Your symptoms depend on which specific pollens you’re allergic to. If you are allergic to tree pollen, you may feel miserable, while someone allergic only to grasses may not yet notice any problems,” says allergist Cherie Zachary, MD, president of the American College of Allergy, Asthma and Immunology (ACAAI).
For those with tree pollen allergies, timing is critical. Tree pollen is already emerging in some warmer regions of the United States, making early March the ideal time to begin preventive treatment.
“People with tree pollen allergies should start taking their allergy medications at least a month before their symptoms typically appear,” says Dr. Zachary. “Starting early helps prevent the immune system from mounting a full-blown response once pollen levels rise.”
Climate change means some areas experience milder winters and earlier warm spells, causing allergy season to begin sooner than expected. An early spring can prime the immune system earlier. If trees start pollinating ahead of schedule, those with spring allergies may notice their symptoms appearing earlier, too. Allergy testing can help determine your specific triggers, and understanding your individual sensitivities is key to effective management.
Spring allergies can cause sneezing, nasal congestion, itchy eyes, wheezing, coughing and fatigue. Many people turn to over-the-counter antihistamines or nasal sprays for relief — and for some, that may be enough. “It’s important to treat your allergies according to your symptoms,” Dr. Zachary advises. “If over-the-counter medications aren’t adequately controlling your symptoms, it’s time to see an allergist.” Board-certified allergists can provide personalized treatment plans tailored to a patient’s specific triggers and symptoms. This may include prescription medications, environmental control strategies, or longer-term solutions.
For those seeking more lasting symptom control, allergen immunotherapy might be an option. Available as allergy shots or tablets, immunotherapy works by gradually training the immune system to tolerate allergens. Allergen immunotherapy helps the body build resistance to the effects of allergens while reducing the intensity of symptoms over time. It doesn’t just mask symptoms — it addresses the underlying allergic response. Immunotherapy can significantly reduce reliance on medications and improve quality of life for many patients, including those with asthma.
When the first signs of spring hit, it’s tempting to open windows for fresh air. However, that can make allergy symptoms worse. Allergists advise that if you have pollen allergies, you should keep windows closed in both your home and your car. Open windows allow pollen to enter, which can trigger sneezing and wheezing. Use air conditioning instead, and high-efficiency air filters to help keep indoor air cleaner. Showering and changing clothes after spending time outdoors can also reduce pollen exposure inside the home.
As spring starts to approach, advance planning and individualized care can make all the difference.
“With the right strategy, people with allergies don’t have to dread spring,” says Dr. Zachary. “Early treatment, environmental precautions, and guidance from an allergist can help keep symptoms under control so you can enjoy the season.”
