Allergy Season Returns with Greater Intensity as Pollen Periods Lengthen
Allergy season has commenced earlier than usual this year, bringing with it a surge in symptoms such as itchy eyes, sneezing, and nasal congestion. Experts warn that pollen seasons are now longer and more intense, driven by climate change and shifting weather patterns.
Why Allergy Seasons Are Growing Longer and More Severe
Dr. Katelyn Jetelina, an adjunct professor of epidemiology at the Yale School of Public Health, explains that warmer, shorter winters reduce periods of freezing temperatures. This extends the growing season for plants, causing them to release pollen earlier in the spring and later into the fall. According to a 2021 study, warming global temperatures and an increase in extreme weather events have lengthened the pollen season in North America by 20 days compared to 1990.
In both the United States and the United Kingdom, seasonal allergies, also known as allergic rhinitis or hay fever, are typically triggered by tree pollen in the spring, grass pollen in the summer, and weed pollen in the fall. Approximately 26% of adults in both countries suffer from seasonal allergies, along with about 19% of children in the US and 10-15% of children in the UK.
Dr. Jetelina notes that even individuals without allergies may experience increased respiratory irritation due to these prolonged pollen seasons.
Identifying and Managing Seasonal Allergy Symptoms
Common symptoms of pollen allergies include itchy, watery eyes, an itchy and runny nose, sneezing, nasal congestion, post-nasal drip, headaches, sore throat, coughing, wheezing, and difficulty breathing, as described by Dr. Arveen Bhasin, an allergist-immunologist at the Mayo Clinic in Jacksonville, Florida. It is possible to develop allergies at any age, and moving to a new environment with different foliage can trigger sensitivities, typically taking about two years to manifest, according to Dr. Payel Gupta, a spokesperson for the American College of Allergy, Asthma and Immunology.
To manage symptoms, over-the-counter medications such as decongestants, antihistamine pills, nasal sprays, and eye drops are recommended. Dr. Bhasin emphasizes the importance of starting these treatments at least two weeks before pollen season for optimal effectiveness. However, antihistamines can lose efficacy over time, and nasal sprays require consistent use for 10-14 days to reach maximum benefit. Experts caution against overusing decongestants, which can cause a rebound effect and worsen congestion, and advise consulting a doctor before use if you have conditions like high blood pressure or heart disease.
Lifestyle Adjustments to Reduce Pollen Exposure
Lifestyle changes can significantly reduce exposure to pollen. Since people spend up to 90% of their time indoors, it is crucial to minimize pollen entry into homes. Keep windows closed, use air conditioning with clean filters, and consider wearing a mask outdoors during high pollen counts. Upon returning home, remove shoes, shower, and change into fresh clothes to prevent pollen from lingering on skin and fabrics. Air purifiers can also be effective, but ensure they are appropriately sized for your space to maximize efficiency.
When to Seek Professional Medical Assistance
If over-the-counter medications and lifestyle adjustments do not alleviate symptoms, consulting an allergist is advised. Allergists may prescribe allergy immunotherapy, such as allergy shots or sublingual treatments, for longer-term control and relief. Dr. Gupta reassures that there are numerous ways to help patients feel more comfortable during allergy season.
As pollen seasons continue to intensify, staying informed and proactive is key to managing allergies effectively and maintaining overall health and wellbeing.
