How To Avoid Asthma Triggers

What is an asthma trigger?

An asthma trigger is anything that causes or worsens asthma symptoms. Triggers can include environmental factors, certain activities or even emotional responses. These triggers are different for everyone, and they can lead to coughing, wheezing, chest tightness or shortness of breath. 

Understanding your asthma triggers is the first step to managing them. Some symptoms may happen right after exposure, while others may appear hours later. It can take time to figure out all your triggers, but keeping track of them can help you reduce flare-ups and feel more in control. 

If you’re unsure what’s causing your asthma symptoms, the team at Banner Health is here to help. 

Common asthma triggers 

Allergens 

If you have allergic asthma, substances that trigger allergies can also trigger asthma. These include: 

• Dust mites 
• Mold 
• Pet dander 
• Pollen 
• Cockroaches 
• Rodents 

Irritants 

People with non-allergic asthma may react to environmental irritants, such as: 

• Cigarette smoke 
• Air pollution 
• Wood fires and charcoal grills 
• Chemical fumes or strong cleaning products 
• Paint, gasoline or perfume odors 
• Dust from construction or industrial settings 

Health conditions 

Some medical issues can make asthma symptoms worse or harder to control: 

• Respiratory infections (like colds or the flu) 
• Gastroesophageal reflux disease (GERD) 
• Sleep apnea 
• Obesity 
• Pregnancy 

These conditions may increase inflammation in your airways or make breathing more difficult, especially at night. 

Exercise 

Cardio exercise - especially in cold or dry air - can trigger asthma symptoms in some people. This is known as exercise-induced bronchoconstriction. Light activities like walking are usually well-tolerated. 

Weather 

Weather can play a role in asthma flare-ups. Triggers may include: 

• Cold, dry air 
• Sudden changes in temperature 
• High humidity 
• Thunderstorms (due to increased pollen and dust in the air) 

Emotions and stress 

Strong emotions like fear, anger or anxiety can lead to faster breathing, which can trigger symptoms or even cause an asthma attack. 

Medications 

Some medications, such as aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), may worsen asthma in certain people. Be sure to tell your doctor about all the medications you take - both prescription and over-the-counter. 

Tips for avoiding asthma triggers 

The best way to reduce asthma flare-ups is to identify and avoid your personal triggers. Here’s how: 

• Keep an asthma journal. Write down your symptoms, when they happen and what you were doing or exposed to at the time. Note the severity and how long they last. 
• Watch for patterns. This can help you figure out which triggers are most likely affecting you. 
• Bring your journal to your appointments. Your doctor can help you make connections and adjust your asthma care plan. 

Avoiding asthma triggers may not eliminate symptoms completely, but it can help you stay in control and reduce the number and severity of asthma attacks.
