Allergies are no longer just a seasonal nuisance. With rising global temperatures and shifting weather patterns, pollen seasons are growing longer and more intense, impacting millions of allergy sufferers across the U.S. At the same time, emerging studies suggest that long-term use of antihistamines—commonly used to manage allergies—may be associated with potential cognitive side effects, especially in older adults.
At South Bay Allergy and Asthma Group, we’re committed to helping patients find lasting relief. One promising solution that addresses both of these challenges is allergy immunotherapy, a treatment that works to retrain your immune system for long-term symptom control—without the need for lifelong medication.
🌿 The Impact of Global Warming on Allergy Seasons
Scientific research continues to show that climate change is intensifying allergy conditions. Here’s how:
- Longer growing seasons: Trees and grasses are producing pollen earlier in the spring and continuing later into the fall.
- Higher pollen counts: Increased CO₂ levels stimulate plants to produce more pollen, aggravating symptoms for many individuals.
- Wider pollen distribution: Warmer temperatures allow allergenic plants to spread to new regions, exposing more people to unfamiliar allergens.
The result? A longer, more severe allergy season for people who were already suffering—and new symptoms for those who previously had none.
🧠 Rethinking Long-Term Antihistamine Use
Antihistamines are the most common over-the-counter remedy for allergic symptoms. While effective in the short term, research suggests that long-term use—especially of first-generation antihistamines like diphenhydramine (Benadryl)—may be associated with cognitive decline, including memory problems and increased risk of dementia in older adults.
Even second-generation antihistamines, though considered safer, are not risk-free when taken continuously for years.
💉 Allergy Immunotherapy: A Smart, Long-Term Solution
Allergy immunotherapy works by gradually desensitizing your immune system to specific allergens, reducing or even eliminating symptoms over time. There are two main types:
- Subcutaneous Immunotherapy (SCIT) – Allergy shots administered in our clinic
- Sublingual Immunotherapy (SLIT) – Tablets dissolved under the tongue (available for select allergens)
Benefits of immunotherapy include:
- Decreased reliance on daily medications
- Improved symptom control
- Long-term relief, even after treatment ends
- Reduced risk of developing asthma in allergic children
