Asthma and allergies affect thousands of Bermudians, but the good news is that with the right knowledge and proactive steps, families can take control.
Nicola MacDougall, CPT, the new Asthma & COPD Educator at Open Airways, is passionate about helping residents breathe easier.
Ms MacDougall shared tips for managing asthma in Bermuda’s unique environment, highlighting how simple changes in our homes can make a big difference.
Our humid climate
Bermuda’s lush greenery and mild weather may feel idyllic, but it creates a tricky environment for asthma management.
“Humidity here acts like a blanket covering the island — it traps allergens in the air and makes them more concentrated,” Ms MacDougall explained.
She highlighted how high humidity becomes the perfect breeding ground for common asthma and allergy triggers such as mould, dust mites and cockroaches; meanwhile our year-round plant growth results in constant pollen production.
“This combination of factors means we have a lot more asthma triggers inside our homes compared to other places,” she added, “because these triggers thrive in high humidity.”
Hidden triggers
While we often focus on outdoor allergies like pollen, many asthma triggers are hiding in plain sight in Bermudian homes.
“Mould is a big one. It can be lurking in carpets, curtains, air conditioning filters, pillows and fabric furniture,” Ms MacDougall said.
“Dust mites are another common problem, especially in bedding and pillows.”
Strong scents can also be surprisingly challenging for asthma sufferers.
“Flowers, candles, plug-in air fresheners, Vicks VapoRub, and even smoke can trigger symptoms. And here’s one most people don’t think about: cockroach – including their saliva, droppings and body parts. They’re allergens too.”
Simple steps
For families looking to minimise allergens in a humid environment, Ms MacDougall has practical advice. “One of the best things you can do is to keep your home well-ventilated. Open windows whenever possible to get fresh air inside,” she recommended.
When it comes to cleaning, Ms MacDougall advised against using harsh chemicals, bug sprays or scented air fresheners.
“Instead, clean hard surfaces and mould patches using a microfiber cloth and white vinegar — it’s antibacterial and kills mould naturally.”
Dry dusting just stirs allergens into the air. “Use a vacuum and wet mop; otherwise, the dust hangs around for two days, making it harder to breathe.”
Ms MacDougall also emphasised the importance of keeping bedding allergen-free.
“Wash bedding every week in hot water and make sure it’s dried thoroughly. Pillows should be washed monthly and replaced annually.”
Young children’s soft toys can be placed in the freezer for six hours once a week to kill off dust mites.
Pets, too, can contribute to asthma issues.
“Most pets have dander, so try to keep them outside as much as possible. When they do come inside, I suggest to keep them out of the bedroom, especially if you’re prone to allergies or asthma symptoms.”
Spotting symptoms
Parents often struggle to distinguish between everyday allergies and asthma symptoms in kids. Ms MacDougall said: “Allergies tend to cause mild nasal congestion, sneezing or occasional coughing. Asthma, on the other hand, involves inflammation, mucus and narrowing of the airways, which leads to wheezing, chest tightness, and difficulty breathing.”
She noted that asthma symptoms could occur outside of allergen exposure.
“Children may wheeze after exercise, laughing, crying, or even while sleeping. If you think your child has more than just allergies, we encourage you to talk to your doctor.”
Open Airways
Open Airways offer free resources and consultations — no referral needed. They also conduct complimentary home visits to help identify triggers and educate families on asthma management. “Our goal is simple: help people understand their asthma, manage their triggers effectively, and use medications correctly,” Ms MacDougall said.
