Common Triggers of Asthma During Seasonal Change That You Need to Stay Safe From

Seasonal changes can be challenging for people with asthma. A shift in temperature, humidity, air quality, and allergens can irritate the airways and make asthma symptoms worse. Wheezing, coughing, chest tightness and shortness of breath may become more frequent during these periods.

Understanding common seasonal triggers and taking simple precautions can help people with asthma reduce their risk of flare-ups.

1. Pollen

Pollen from trees, grasses, and weeds is a common asthma trigger, particularly during spring and early summer. When pollen levels are high, inhaling these tiny particles can cause inflammation in sensitive airways.

People who are allergic to pollen may experience sneezing, a runny nose, and itchy eyes along with asthma symptoms. Keeping windows closed when pollen levels are high and showering after spending time outdoors can help reduce exposure.

2. Sudden Changes In Temperature

Moving between hot and cold environments can sometimes trigger asthma symptoms.

According to a study published in the journal 'European Respiratory Review', cold, dry air can cause the airways to narrow, while very hot and humid conditions may make breathing uncomfortable.

During sudden weather changes, people with asthma should protect themselves from extreme temperatures. Covering the nose and mouth with a scarf in cold weather can help warm the air before it reaches the lungs.

3. Respiratory Infections

Seasonal changes can coincide with an increase in colds, flu and other respiratory infections. Viral infections can irritate the airways and trigger asthma attacks.

Regular handwashing, avoiding close contact with people who are unwell, and following recommended vaccinations can help reduce the risk of respiratory infections. People with asthma should also follow their prescribed treatment plan if they develop a cold or flu.

4. Dust And Indoor Allergens

As weather conditions change, people may spend more time indoors, increasing exposure to dust, dust mites, mould and pet allergens. These can irritate the airways and trigger symptoms in sensitive individuals.

Regularly cleaning bedding, reducing dust accumulation and keeping indoor spaces well ventilated can help. If mould is present, it should be addressed promptly because mould spores can worsen asthma and allergies.

5. Mould And Dampness

Changes in humidity and rainfall can create damp conditions that encourage mould growth. Mould spores can become airborne and may trigger asthma symptoms.

Bathrooms, kitchens, walls, and poorly ventilated areas are common places for mould to develop. Keeping indoor humidity under control and fixing water leaks can reduce mould exposure.

6. Air Pollution

According to the European Lung Foundation, air pollution can become particularly problematic during certain seasons. Smoke, vehicle emissions, fine particulate matter and other pollutants can irritate the respiratory system.

People with asthma should check local air-quality information when possible and limit strenuous outdoor activity when pollution levels are high. Avoiding cigarette smoke and indoor burning of substances such as incense or wood can also reduce exposure to irritants.

7. Thunderstorms

Thunderstorms can sometimes worsen asthma symptoms, particularly during pollen seasons.

Strong winds and changes in humidity can break pollen and other allergens into smaller particles that can become easier to inhale.

People who know that thunderstorms trigger their asthma should be particularly careful during periods of high pollen and storm activity and keep their prescribed reliever medicine readily available.

8. Smoke From Fires And Burning

Seasonal festivals, agricultural burning, wildfires and household fires can increase exposure to smoke and fine particles. Smoke can irritate the airways even in people who are not allergic.

Avoiding smoky environments and ensuring good ventilation indoors can help. People with asthma should never smoke and should avoid exposure to second-hand smoke.

9. Strong Fragrances And Chemical Fumes

Changes in weather are not the only concern. Cleaning products, perfumes, air fresheners, paints and other strong fumes can trigger symptoms in some people.

Using fragrance-free products where possible and ensuring adequate ventilation can help minimise exposure.

Tips To Keep Your Asthma Under Control

The best protection is to understand your personal triggers and follow the asthma treatment plan recommended by your doctor.

• Take prescribed preventer medicines regularly, even when you feel well, if your doctor has advised this.
• Keep your reliever inhaler accessible and make sure you know how to use your inhaler correctly.
• Seek urgent medical help if breathing becomes severely difficult, symptoms rapidly worsen, or your reliever medicine is not providing the usual relief.

Final Word

Seasonal changes cannot always be avoided, but many asthma triggers can be managed. By monitoring the weather and air quality, reducing exposure to allergens and irritants, preventing infections and following prescribed treatment, people with asthma can stay safer and breathe more comfortably throughout the year.
