As winter chill thaws and the spring flowers begin to bloom, many of us find ourselves grappling with the unwelcome return of sneezing, itching, and congestion that signals spring allergy season. This year, like nearly every in the last decade, seems to have arrived earlier—a trend that’s becoming increasingly common. As a physician specializing in allergy and immunology, I’ve observed firsthand the impact of climate change and air pollution on our health, particularly when it comes to allergies.
The early onset of allergies: a closer look
The primary reason we’re seeing spring allergies emerge earlier each year is due to the extended warmer temperatures and increased carbon dioxide brought on by and associated with climate change. This shift not only lengthens the allergy season but also intensifies it. Compounding the issue is air pollution, which transforms pollen into a more potent allergen. Air pollutants may act as carriers for allergens in the airways and increase the antigenicity of the pollen grains. This “aggressive” pollen can provoke more severe symptoms, potentially affecting a larger portion of the population. It’s estimated that by 2050, 50% of us will suffer from some form of allergy, highlighting the need for increased awareness and action.
Why allergy symptoms are worsening
In recent years, allergy symptoms have intensified. Factors such as rising temperatures, more prevalent grass and weed pollen, and the reduction in mask-wearing have all played a role. These environmental and behavioral changes lead to higher pollen production and exposure, exacerbating allergic reactions for many of us.
Decoding seasonal allergies
At their core, seasonal allergies are the result of our body’s overreaction to harmless substances like pollen. When pollen enters our system, it triggers the production of specific antibodies, leading to the activation of allergy cells. This cascade of reactions causes the symptoms many of us are all too familiar with: sneezing, congestion, and itchy eyes.
Reducing pollen exposure: practical tips
To help mitigate the impact of pollen, I’ve compiled a few strategies based on my experience and the latest research:
- Keep windows closed: Limiting outdoor air in your home can significantly reduce indoor pollen levels.
- Shower after outdoor activities: Washing away pollen from your body and hair can prevent prolonged exposure.
- Regular hand washing: Minimizing pollen transfer to your eyes and nose can reduce irritation.
- Exploring innovative solutions: You might consider trying out Allegra Airways. This innovative web-based tool offers real-time, hyperlocal pollen and pollution data to help you plan outdoor activities like a hike or a bike ride while minimizing exposure.
Proactive management of allergy symptoms
Starting your allergy medication a few weeks before the season hits its peak can make a significant difference. It’s crucial to identify the specific allergens that trigger your reactions and choose a medication that addresses your needs, such as a non-drowsy antihistamine or a nasal corticosteroid for daily use.
Seeking professional guidance
It’s essential to consult with your health care provider before introducing any new medication into your routine. If over-the-counter solutions don’t provide relief, it may be time to seek advice from a specialist. As an allergist, I often work with patients to tailor a treatment plan that addresses their unique situation, exploring options like immunotherapy for long-term relief. Although immunotherapy has been strictly allergy shots for years, newer approaches are increasingly available, including sublingual and intralymphatic approaches, which can provide increased convenience and less risk of reactions.
As we navigate another allergy season, it’s clear that the landscape of allergic diseases is evolving. By understanding the factors at play and adopting proactive measures, we can better manage our symptoms and enjoy the beauty of spring. Remember, you’re not alone in this struggle, and there are resources and professionals ready to support you in finding relief.
Kara Wada is a quadruple board-certified pediatric and adult allergy and immunology, lifestyle, and functional medicine physician, a Sjögren’s disease specialist, and a Sjögren’s patient herself. She spent nine years on faculty at The Ohio State University Wexner Medical Center, where she served as associate program director of the allergy and immunology fellowship and led the Mast Cell Center of Excellence.
In 2025, she left academic medicine to build the kind of practice she could not find as a patient: the Immune Confident Institute, a national direct-care immunology practice licensed in 27 states. She treats the patients the health care system sends ping-ponging between specialists, people with complex, chronic, multisystem disease including mast cell activation syndrome (MCAS), dysautonomia, Sjögren’s disease, immune dysfunction, and the seronegative and “in-between” diagnoses that do not fit neatly into a single specialty.
Her premise is simple: These patients are not the problem. Fragmented care is. Medicine has become exceptionally good at looking through microscopes while losing sight of the telescope, the bigger picture of the person in front of us. Her work challenges a health care culture that demands compliance when it should assume competence, and aims to make strategic, compassionate immune-directed care the standard, and the exam room a place where patients are finally seen, heard, and believed.
Most of her reach is built outside the exam room. Her YouTube channel drew roughly two million views this past year, and more than 100,000 people follow her work across platforms, including a Sjögren’s community of about 6,600. She founded and hosts the Virtual Sjögren’s Summit, now in its sixth year and drawing some 4,300 registrants worldwide. She appears regularly on national television and in the health press, including Prevention, SELF, Good Housekeeping, WebMD, Medscape, and MedPage Today, and she writes for KevinMD on the diagnoses that live in the shadows and the medical gaslighting that surrounds them.
A TEDx speaker and sought-after keynote, Wada speaks to clinician and patient audiences about complex immune disease, the experience of being disbelieved, and what changes when the physician is also the patient. She is also an unlikely pageant titleholder, having served as Dr. Ohio America 2022 and Dr. Midwest America 2023, and has written about how pageantry sharpened skills medicine rewards but rarely teaches.
She earned her medical degree with honors from the University of Illinois College of Medicine at Peoria and completed internal medicine-pediatrics residency, allergy and immunology fellowship, and clinician educator fellowship at The Ohio State University and Nationwide Children’s Hospital. She lives in Columbus, Ohio, with her medical school sweetheart turned husband, Akira, and their three children.
