Asthma Awareness Month 2026: What South Florida Patients Need to Know

May is National Asthma and Allergy Awareness Month 2026, and if you live in South Florida, it is more relevant to your health than you may realize.

Declared each May since 1984 by the Asthma and Allergy Foundation of America (AAFA), this year’s theme is “The Power of Community to Improve Asthma and Allergy Health”, a call for patients, families, and healthcare teams to work together to close treatment gaps and improve outcomes. In the United States, more than 27 million people live with asthma, and across the globe that number exceeds 262 million, according to the World Health Organization.

For patients in Boynton Beach, Atlantis, and across Palm Beach County, the South Florida climate adds a dimension to asthma management that most other US cities do not face: triggers that do not follow a season and do not take a break. Understanding those triggers and knowing when to see a specialist is what this guide is designed to help you do.

What Is Asthma? A Quick Clinical Overview

Asthma is a chronic inflammatory disease of the airways in which the bronchial tubes become narrowed, swollen, and produce excess mucus. The result is recurring episodes of wheezing, chest tightness, shortness of breath, and coughing, particularly at night or during physical activity.

According to the National Heart, Lung, and Blood Institute (NHLBI), asthma is classified along a spectrum of severity ranging from mild intermittent to severe persistent, and it can affect people at any age. While there is currently no cure, consistent, specialist-guided management significantly reduces symptoms, hospitalizations, and long-term airway damage.

The Centers for Disease Control and Prevention (CDC) estimates that asthma costs the United States healthcare system more than $80 billion per year, with a significant proportion of that burden driven by preventable emergency visits and hospitalizations in patients with undertreated disease.

Not Sure If You Have Asthma?

Many South Florida patients live with undiagnosed asthma for years, managing it as a “persistent cough” or “allergies.” A 15-minute spirometry test gives you a definitive answer.

Why South Florida Creates a Distinct Asthma Challenge

Most patients picture asthma flare-ups as a spring or autumn problem tied to pollen season. In South Florida, that model does not apply.

South Florida has no sustained low-allergen season. Year-round warmth, elevated humidity levels that regularly exceed 70%, and a subtropical plant ecosystem combine to keep multiple asthma triggers active in nearly every month. Below are the specific environmental factors that separate South Florida’s asthma burden from the national average.

Humidity and Airway Inflammation

High ambient humidity is not just uncomfortable; it is a direct physiological asthma trigger. A 2024 systematic review published in PubMed Central (PMC) found that high humidity disrupts the airway epithelial barrier, impairs mucus clearance by cilia, and activates the Th-2 inflammatory cascade, the same immune pathway that drives allergic asthma.

Specifically, humidity levels exceeding 90% have been shown to induce oxidative stress, activate the TRPV1 sensory nerve pathway in the airways, and promote type I hypersensitivity reactions. In South Florida, where summer humidity routinely exceeds these thresholds, these mechanisms are regularly in play for sensitive patients.

If your asthma symptoms consistently worsen when you step outside, particularly in the morning or after afternoon rain, humidity-triggered bronchoconstriction is a likely explanation, and it warrants specialist evaluation.

Bahia Grass Pollen: South Florida’s Most Potent Grass Allergen

Bahia grass (Paspalum notatum) is the dominant ground cover across Florida’s roadsides, parks, golf courses, and residential lawns. Research published in PubMed identifies Pas n 13 as a clinically significant Bahia grass allergen “likely to be important in eliciting seasonal allergic rhinitis and asthma in grass pollen-allergic patients.”

Bahia grass has a pollen season that typically runs from April through October in South Florida, with its peak intensity in May and June, a window that is nearly twice as long as typical northern grass pollen seasons.

Critically, Bahia grass has limited cross-reactivity with ryegrass and timothy grass, the grasses commonly tested in standard allergy panels outside of Florida. A PubMed study (PMID 15647049) confirmed that while Bahia grass-specific IgE is common in seasonal rhinitis patients in subtropical regions, it is not reliably identified through generic grass panels. This means many South Florida patients with uncontrolled asthma may have undiagnosed Bahia grass sensitization that a Florida-specific allergen panel would identify.

Have You Been Tested for Bahia Grass Allergy?

Standard allergy panels often miss Bahia grass, South Florida’s most potent grass allergen. Our Florida-specific skin testing identifies your exact trigger profile so treatment can actually target the cause.

Year-Round Mold Exposure

South Florida’s combination of heavy summer rains, standing water, and warm building microclimates creates persistent mold spore counts throughout the year. According to the U.S. Environmental Protection Agency (EPA), mold is a well-established asthma trigger, alongside dust mites, outdoor air pollution, and pollen.

Mold spore levels in South Florida typically peak from June through September during the rainy season, but elevated counts persist year-round in buildings with humidity control issues, flood history, or older HVAC systems. The most allergenic genera (Cladosporium, Alternaria, Aspergillus) are all present in the Palm Beach County environment.

Dust Mites: The Always-Present Indoor Trigger

Dust mites thrive in warm, humid indoor environments. Because South Florida’s climate maintains high indoor humidity year-round, dust mites, one of the most significant triggers documented by the EPA, remain at high population levels in mattresses, bedding, upholstery, and carpeting in every season.

Patients whose asthma symptoms are consistently worse indoors, at night, or upon waking should specifically discuss dust mite sensitization with their specialist during evaluation.

Recognizing Asthma Symptoms: What to Watch For

According to the Florida Health Finder (Florida Agency for Health Care Administration), common asthma triggers in Florida include pollen, dust mites, mold, and pet dander, the same categories that are uniquely elevated in South Florida’s climate. Knowing the symptoms that these triggers provoke helps you act before a flare escalates.

Common asthma symptoms include:

• Shortness of breath — difficulty breathing during physical activity, in humid outdoor air, or at rest during severe episodes
• Chest tightness or pressure — often described as squeezing or heaviness across the chest
• Wheezing — a high-pitched whistling sound when breathing out, particularly after outdoor exposure or exercise
• Persistent cough — especially at night, early morning, or in high-pollen environments; often dry and recurring
• Rapid breathing — breathing faster than normal without exertion
• Difficulty completing sentences — during active asthma episodes, breathlessness interrupts normal speech

Early Warning Signs Before a Full Flare

The NHLBI identifies early warning signs that precede a full asthma attack, recognizing these gives you time to respond before symptoms escalate:

• Needing your rescue inhaler more frequently than usual
• Unusual fatigue or irritability without another clear cause
• Waking during the night from coughing or wheezing
• Symptoms that reliably worsen in specific outdoor environments

When Symptoms Are Being Mistaken for Something Else

A pattern our allergy and immunology team sees regularly: patients managing a “persistent cough”, “recurring sinus infections”, or “exercise intolerance” with over-the-counter remedies for months before receiving an accurate asthma diagnosis. If your respiratory symptoms have not fully resolved with standard allergy medications, a formal lung function evaluation is the appropriate next step.

How Asthma Is Diagnosed and Treated

Diagnosis: What a Specialist Evaluation Covers

Current GINA 2025 guidelines identify spirometry as the gold standard for asthma diagnosis, a simple, non-invasive test measuring how much air you can exhale and how fast. Fractional Exhaled Nitric Oxide (FeNO) testing, which measures airway inflammation at a molecular level, is used as a confirmatory tool when FeNO values exceed 50 ppb in adults.

At Florida Allergy & Asthma Associates, a full diagnostic evaluation also includes:

• Comprehensive allergy skin testing — using a Florida-specific allergen panel that covers Bahia grass, local tree species, regional mold genera, and dust mite species common to Palm Beach County
• Detailed trigger history — including outdoor activity patterns, occupational exposure, home humidity levels, and Florida-specific environmental context
• Review of current medication use — including frequency of rescue inhaler use, which GINA identifies as a key indicator of asthma control status

Treatment: Moving Beyond Symptom Management

Effective asthma treatment in South Florida requires addressing both the inflammatory condition and its specific triggers. Current evidence-based options include:

• Daily inhaled corticosteroids (ICS) — the gold-standard controller therapy for reducing chronic airway inflammation; recommended by GINA as first-line treatment for persistent asthma
• Short-acting beta-agonists (SABA/rescue inhalers) — for immediate symptom relief during flares; frequent use signals undertreated disease
• Biologic therapies — for moderate-to-severe or difficult-to-control allergic asthma, targeted biologics reduce inflammation at the immune pathway level
• Allergy immunotherapy or allergy shots — for patients with allergic asthma, subcutaneous immunotherapy desensitizes the immune system to its specific triggers over a 3–5 year course; PubMed research (PMID 22832594) confirms immunotherapy is effective for grass pollen allergy, including Bahia grass, the most relevant grass species in South Florida
• Written Asthma Action Plan — every patient receives a personalized Green/Yellow/Red zone plan guiding their response to changing symptoms, consistent with GINA best-practice recommendations

Could Allergy Shots Reduce Your Asthma?

For patients with allergic asthma, immunotherapy treats the root cause — not just the symptoms. Our allergists will determine if you are a candidate at your first visit.

When to See an Asthma Specialist in Boynton Beach or Atlantis

Primary care provides valuable baseline management, but asthma that involves allergic triggers, variable control, or frequent exacerbations consistently benefits from specialist evaluation. Schedule an appointment with our team at Florida Allergy & Asthma Associates if:

• You use your rescue inhaler more than twice a week
• Asthma symptoms wake you at night on a recurring basis
• You have never had spirometry or formal lung function testing
• You have never had comprehensive allergy testing to identify your specific South Florida trigger profile
• Symptoms are not adequately controlled despite current medications
• You relocated to South Florida and have experienced new or worsening respiratory symptoms
• You have visited an emergency room or been hospitalized for asthma in the past year

Frequently Asked Questions

Q1: When is Asthma Awareness Month 2026?

Ans: National Asthma and Allergy Awareness Month 2026 runs throughout the entire month of May. Since 1984, AAFA has designated May as the official awareness month, timing it to coincide with peak pollen and allergen season across the United States. This year’s 2026 theme is “The Power of Community to Improve Asthma and Allergy Health.”

Q2: What are the most common asthma symptoms?

Ans: The most common asthma symptoms include shortness of breath, persistent coughing (especially at night or early morning), chest tightness or pressure, and wheezing — a high-pitched sound when breathing out. Symptoms often worsen during physical activity, in high-humidity environments, or during periods of elevated pollen or mold counts. If these symptoms occur regularly, a formal asthma evaluation with spirometry is recommended.

Q3: What triggers asthma in South Florida specifically?

Ans: South Florida’s primary asthma triggers include Bahia grass pollen (peaks May–June), year-round mold spores (highest during the summer rainy season), high ambient humidity, oak and melaleuca tree pollen (peaks January–April), dust mites in indoor environments, and air quality fluctuations. Because Florida’s climate maintains allergen activity year-round, South Florida patients are often exposed to multiple overlapping triggers simultaneously, a factor that makes specialist evaluation and comprehensive allergy testing particularly important.

Q4: Can allergies cause asthma?

Ans: Yes, allergic asthma is the most common form of asthma. When the immune system is sensitized to allergens such as Bahia grass pollen, mold spores, or dust mites, exposure triggers both the nasal symptoms associated with allergic rhinitis and the airway inflammation that defines asthma. This is known as the “unified airway” model, recognized by both GINA and NHLBI guidelines. Treating the underlying allergic sensitization through allergy immunotherapy reduces both allergy and asthma severity simultaneously.

Q5: What does an asthma attack feel like?

Ans: During an asthma attack, the airways narrow rapidly, making it difficult to get air in and out. Patients typically describe intense shortness of breath, a feeling of tightness or squeezing across the chest, audible wheezing when breathing out, and an uncontrollable cough that does not bring relief. In severe episodes, breathing becomes labored enough to interrupt speaking, and lips or fingernails may appear bluish, a sign of oxygen reduction requiring emergency medical attention. Knowing your personal early warning signs and having a written Asthma Action Plan helps prevent episodes from escalating to this level.

Q6: How is asthma diagnosed?

Ans: Asthma is diagnosed through a combination of symptom history and objective lung function testing. Current GINA 2025 guidelines identify spirometry as the gold standard, measuring airflow rate and lung volume to detect the characteristic variable airflow limitation of asthma. FeNO (Fractional Exhaled Nitric Oxide) testing, which measures airway inflammation directly, is used alongside spirometry when values exceed 50 ppb in adults. A comprehensive allergy panel identifying specific sensitizations is also a standard part of asthma evaluation at specialist centers.

Q7: Is there a cure for asthma?

Ans: There is currently no cure for asthma. However, with consistent specialist-guided care, the majority of asthma patients achieve full symptom control, meaning no limitations on activity, no nighttime symptoms, and minimal or no need for rescue medication. For patients with allergic asthma, allergy immunotherapy (allergy shots) is the one treatment that modifies the underlying immune response and produces long-lasting benefits that continue after the treatment course is completed.

Q8: How can I control asthma during South Florida’s grass pollen season?

Ans: Controlling asthma during Bahia grass pollen season (May–June in South Florida) requires a multi-layered approach: consistent use of your daily controller inhaler as prescribed, monitoring local pollen counts and limiting outdoor activity during peak morning hours on high-count days, keeping windows closed and running air conditioning with a HEPA filter during peak pollen weeks, and, for patients with confirmed Bahia grass sensitization, discussing the role of allergy immunotherapy in reducing long-term sensitivity. A personalized Asthma Action Plan from your allergist provides season-specific guidance for your exact trigger profile.
