Seasonal Asthma: Understanding the Causes, Symptoms, and Treatments

What is Seasonal Asthma?

Seasonal asthma, also known as allergic asthma, is a chronic condition that can make breathing difficult. It’s not limited to a specific time of year, and its triggers can vary depending on the environment and individual circumstances.

Common Triggers of Seasonal Asthma

Several factors can contribute to seasonal asthma, including:

Pollen

Pollen is one of the most common allergens that can trigger asthma symptoms. There are different types of pollen that peak at various times of the year, including:

• Tree pollen (March to May)
• Grass pollen (late spring to early summer)
• Weed pollen (late summer to mid-fall)

Cold, Dry Air

Cold, dry air can cause bronchoconstriction, which can trigger asthma symptoms. This is especially true during exercise, when the body requires more oxygen.

Heat and Humidity

Hot and humid weather can make breathing more difficult, especially during exercise. Additionally, humidity can trap allergens like dust mites, smoke, and pollen, exacerbating asthma symptoms.

Mold and Mildew

Mold and mildew thrive in damp environments and can trigger asthma symptoms. They’re more common in winter months, but can persist throughout the year in hot and humid climates.

Storms

Thunderstorms during peak pollen months can create a perfect storm of symptoms for seasonal asthma sufferers.

Symptoms of Seasonal Asthma

Up to 50% of adult asthma and 80% of childhood asthma is exacerbated by allergies. Common symptoms include:

• Sneezing
• Dry, itchy throat
• Sore, watery, or itchy eyes
• Congestion or runny nose
• Wheezing
• Chest tightness
• Difficulty breathing
• Shortness of breath
• Coughing during sleep, exercise, or laughter

Treatments for Seasonal Asthma

Asthma treatments vary depending on the severity of symptoms. Common options include:

• Combination inhalers
• Rescue inhalers
• Inhaled corticosteroids
• Immunotherapy (allergy shots)
• Leukotriene modifiers
• Mast cell stabilizers

Avoiding Asthma Flare-Ups

To minimize seasonal asthma symptoms, try:

• Staying indoors during peak pollen hours
• Getting checked for pet allergies
• Allergy-proofing your bed
• Examining your home for leaks
• Keeping your home clean
• Watching the humidity level

When to Seek Medical Attention

If you’re experiencing asthma symptoms for the first time, or if your symptoms worsen over time, consult a healthcare professional. Additionally, seek immediate medical attention if you experience:

• Difficulty breathing
• Lips or fingernails turning blue
• Nostrils flaring when breathing in
• Rapid or hard-to-control breathing
• Feeling like you have a heavy weight on your chest
