Springtime often brings a burst of color and life to the outdoors, but it also means itchy eyes, sneezing, and runny noses for millions of people. If you’re wondering why you don’t feel well when flowers bloom or grass is freshly cut, the answer may lie in a common condition affecting people worldwide.
Pollen allergy, also called hay fever or allergic rhinitis, is an allergic reaction triggered when your immune system overreacts to pollen grains released by trees, grasses, and weeds. The body mistakes these tiny particles for harmful invaders, launching a cascade of symptoms ranging from sneezing and congestion to itchy eyes and even asthma. Understanding pollen allergy can help you manage symptoms, reduce exposure, and improve your quality of life.
Pollen is a fine powder that plants produce as part of their reproductive cycle. These microscopic grains are carried by the wind, insects, or animals to fertilize other plants of the same species. While pollen is crucial for plant life, it can be a significant problem for people with allergies. The most troublesome pollens are lightweight and easily airborne, making inhalation and subsequent allergic reactions common during certain seasons.
Pollen allergies develop when the immune system mistakenly identifies harmless pollen as a threat. This triggers the release of chemicals like histamine, leading to the familiar symptoms of allergic rhinitis. Genetics play a significant role — if your parents have allergies, you’re also more likely to develop them. Environmental factors, such as exposure to pollen early in life, also contribute.
Grass, weed, and tree pollen allergy symptoms usually appear soon after exposure. They may include:
Hay fever is another term for allergic rhinitis caused by pollen. Hay fever symptoms often mimic those of a cold but last longer and occur around specific times of the year. If you’d like to learn more about hay fever, visit this page.
For some individuals, pollen can worsen asthma symptoms. Breathing in pollen may lead to coughing, wheezing, shortness of breath, and chest tightness. This link between pollen and asthma is a key reason why effective allergy management is essential for respiratory health.
Pollen allergies can also cause inflammation of the eyes, known as allergic conjunctivitis. Symptoms include red, itchy, and watery eyes, swelling of the eyelids, and sensitivity to light.
Some people with pollen allergies experience reactions to certain raw fruits, vegetables, or nuts — a condition called pollen-food allergy syndrome (oral allergy syndrome). This happens due to cross-reactivity between pollen and similar proteins in foods, leading to symptoms like mouth itching or swelling after eating these foods.
A diagnosis typically begins with a detailed medical history and discussion of your symptoms. Understanding your experiences and their timing helps to determine whether pollen is the likely cause.
Maintaining a symptom diary can be helpful. Note when your discomfort occurs, its severity, and any potential triggers. This record can assist your healthcare professional in diagnosing pollen allergy more accurately.
Diagnostic tests for pollen allergies include:
Both methods help pinpoint the specific types of pollen causing your allergy and asthma symptoms. For more on allergy testing and related conditions, explore our detailed allergy information.
While there are some alternative tests to detect allergies (like hair analysis or applied kinesiology), these methods lack scientific support. Relying on medically validated tests is essential for an accurate diagnosis and effective management.
Several medications can help manage and treat pollen allergy symptoms:
Sublingual allergy drops offer an alternative form of immunotherapy for individuals with pollen allergies who prefer to avoid injections. Instead of shots, this treatment involves placing small doses of the allergen under the tongue daily to help the immune system gradually build tolerance. Over time, sublingual immunotherapy can reduce sensitivity to pollen and lessen symptoms during allergy season. It’s a convenient, needle-free option that can be taken at home.

Simple lifestyle adjustments can make a big difference:
High-efficiency particulate air (HEPA) filters can reduce indoor pollen levels. Use HEPA air purifiers and vacuum cleaners with HEPA filters to help minimize exposure at home.
Some herbal remedies are marketed for allergy relief, but their effectiveness and safety are not always proven. Always consult a healthcare professional before trying herbal treatments, especially if you have other health conditions or take medications.
There is no guaranteed way to prevent developing a pollen allergy, especially if you have a genetic predisposition.
Stay informed about daily pollen levels in your area using weather apps, websites, or local news. Adjust your activities according to pollen forecasts to minimize exposure.
Climate change can increase pollen production and extend the periods of seasonal allergies, leading to more intense and longer-lasting symptoms. Being aware of these changes can help guide your prevention and management strategies.
Living with pollen allergy means being proactive about symptom management. Follow your treatment plan, avoid known triggers, and communicate with your healthcare provider about any changes in your symptoms. Consider using telehealth services for convenient allergy care from home.
If your symptoms interfere with sleep, work, or daily life — or if you experience severe reactions like difficulty breathing — consult a healthcare professional promptly.

First and foremost let me start by saying that these people did one hell of a job figuring out my sinus problems. When I first arrived there, I explained what was going on with me having excessive inflammation in the sinus…after they tested me, I found out that I was being exposed to dust mites which gave me a strong reaction. I followed the doctors guides lines in terms of cleaning my room and ever since, my sinus inflammation went away for good and now I have a healthy sinus. Thank you for everything.
My 10 year old son also has allergies and asthma and the staff makes sure that he feels well taken care of and comfortable, despite his having Autism and ADHD. He actually looks forward to going there with me, whether it be for my allergy shots or even when he needed allergy skin testing. When you’re a patient at the Allergy and Asthma clinic, you are treated as if you are the only patient they have, even when the waiting room is full. Dr. Engler has hired truly excellent staff, from the front desk people to the nurses and medical assistants. If you have allergies and/or asthma and you live on the Peninsula or even in the city, I highly recommend that you visit the Allergy and Asthma Clinic. They are truly amazing and will make you feel so much better.
