Savannah's Sinuses: Spanish Moss Crashing Lungs?

By Franklin Everett Shaw

The air in Savannah, Georgia, hangs heavy with humidity, a constant companion to the city’s historic charm. But that same humidity, combined with the ubiquitous Spanish moss draped across the ancient oaks, can spell trouble for those with respiratory sensitivities. It’s not just the pollen from flowering plants that residents need to worry about; the Spanish moss itself, and what it harbors, can be a significant irritant.

Spanish moss, despite its name, isn’t actually a moss. It’s a bromeliad, related to pineapples, and it doesn’t have roots. It absorbs nutrients and moisture from the air and rainfall. This means it also collects pollen, dust, mold spores, and other airborne allergens, effectively becoming a giant, swaying air filter – a filter that then releases those collected irritants back into the air, especially during dry and windy conditions.

The biggest misconception is that Spanish moss itself is allergenic. While the plant itself is generally not considered a primary allergen, it’s the associated allergens that pose the real threat.

• Pollen: Spanish moss acts as a trap for pollen from various trees, grasses, and weeds common in Savannah. Oak pollen, a major allergen in the spring, gets caught in the moss’s feathery strands. Ragweed pollen, prevalent in the fall, is another common culprit.
• Mold: The humid Savannah climate fosters mold growth, and Spanish moss provides an ideal environment for it. Aspergillus and Penicillium are common mold genera found in Spanish moss, and their spores are potent respiratory irritants.
• Dust mites: While not directly living on the moss, dust mites can be present in the accumulated dust and debris within the moss clumps, especially closer to the tree bark.

For Savannah residents with asthma or allergies, this translates to a prolonged allergy season and potentially more severe symptoms. Symptoms can include:

• Coughing and wheezing: Irritated airways constrict, making breathing difficult.
• Sneezing and runny nose: The body’s attempt to expel the allergens.
• Itchy, watery eyes: A classic allergic reaction.
• Skin rashes: In some cases, direct contact with Spanish moss or its associated allergens can trigger skin irritation.
• Asthma exacerbations: For asthmatics, exposure can lead to a full-blown asthma attack.

So, what can you do to minimize exposure and manage symptoms in Savannah? It’s not about eradicating Spanish moss – that’s neither feasible nor desirable, given its ecological and aesthetic value. It’s about smart mitigation strategies.

1. Know Your Enemy (Allergen Identification): Get tested by an allergist to identify your specific triggers. Knowing whether you’re allergic to oak pollen, mold, or dust mites will help you target your avoidance strategies. Savannah has several excellent allergists who are familiar with the local pollen and mold profiles.

2. Monitor Pollen Counts: Pay attention to local pollen forecasts. Several websites and apps provide daily pollen counts for Savannah. When pollen counts are high, limit outdoor activities, especially during peak pollen times (typically morning).

3. Indoor Air Quality is Key: Invest in a high-quality air purifier with a HEPA filter. Make sure it’s appropriately sized for the room you’re using it in. Change the filter regularly according to the manufacturer’s instructions. Consider a dehumidifier to reduce indoor humidity and inhibit mold growth. Aim for a humidity level between 30-50%.

4. Strategic Home Maintenance:

   • Keep windows and doors closed: Especially during high pollen and mold days.
   • Use air conditioning: Air conditioning filters the air and helps control humidity.
   • Wash bedding frequently: Wash sheets, pillowcases, and blankets in hot water to kill dust mites.
   • Regularly clean surfaces: Dust and vacuum frequently to remove pollen and mold spores.
   • Consider removing carpets: Carpets trap allergens. Hardwood or tile floors are easier to clean.

5. Landscaping Considerations: While you can’t control the Spanish moss on public trees, you can manage the vegetation around your home.

   • Choose low-allergen plants: Opt for plants that produce less pollen.
   • Keep your lawn mowed: This reduces grass pollen.
   • Avoid raking leaves: Raking stirs up pollen and mold spores. Use a leaf blower instead, or wear a mask while raking.

6. Personal Protective Measures:

   • Wear a mask: When doing yard work or spending time outdoors during high pollen or mold days, wear a NIOSH-rated N95 mask.
   • Shower and change clothes: After spending time outdoors, shower and change clothes to remove pollen and mold spores.
   • Use saline nasal rinse: A saline nasal rinse can help clear pollen and irritants from your nasal passages.

7. Medication Management: Work with your doctor to develop a medication plan to manage your allergy or asthma symptoms. This may include antihistamines, nasal corticosteroids, or bronchodilators.

Common Pitfalls and How to Avoid Them:

• Ignoring Indoor Air Quality: Many people focus on outdoor pollen counts but neglect the air quality inside their homes. A good air purifier and regular cleaning are essential.
• Improper Air Purifier Use: Buying an air purifier that’s too small for the room or not changing the filter regularly renders it ineffective.
• Over-Reliance on Over-the-Counter Medications: While over-the-counter medications can provide temporary relief, they don’t address the underlying cause of your allergies. Consult with a doctor for a comprehensive treatment plan.
• Assuming All Spanish Moss is the Same: While the moss itself isn’t the primary allergen, the amount of pollen and mold it collects can vary depending on its location and the surrounding environment. Moss in a shady, humid area will likely harbor more mold than moss in a sunny, dry location.
• Ignoring Mold Issues: Mold is a significant problem in Savannah’s humid climate. Address any mold growth in your home promptly to prevent respiratory problems.

Real-World Scenario:

Consider Mrs. Johnson, a long-time Savannah resident with asthma. She loves the city’s charm but struggles with her asthma symptoms, especially during the spring and fall. After consulting with an allergist, she discovered she was allergic to oak pollen and mold. She invested in a HEPA air purifier for her bedroom, started monitoring local pollen counts, and began using a saline nasal rinse daily. She also had her carpets professionally cleaned to remove dust mites and mold spores. As a result, her asthma symptoms significantly improved, and she was able to enjoy Savannah’s beauty without constant respiratory distress.

Living in Savannah with respiratory sensitivities requires awareness and proactive management. By understanding the potential irritants associated with Spanish moss, monitoring pollen and mold levels, and implementing effective mitigation strategies, residents can breathe easier and enjoy all that this beautiful city has to offer. Don’t let the charm of Savannah be overshadowed by respiratory woes. Take control of your environment and breathe freely.
