Common asthma signs and symptoms include:
- Coughing: Coughing from asthma is often worse at night or early morning. Sometimes it’s your only symptom. It can be dry or mucus filled.
- Wheezing: This is a whistling or squeaky sound especially when you breathe out. Sometimes wheezing can be heard easily; other times you need a stethoscope. A stethoscope is a medical device used to listen to breath sounds.
- Chest tightness: This can feel like something is squeezing or sitting on your chest.
- Shortness of breath: You may feel breathless, like you can’t catch your breath or breathe deeply enough. You may feel as though you are out of shape and constantly tired.
What triggers asthma symptoms?
It is important to understand what triggers your asthma symptoms. Asthma is not a one-size-fits-all disease – what sets off symptoms for you or someone in your family may be quite different from what affects others. When you understand what’s happening inside your lungs and how they respond to allergens and irritants like pollen, dust mites or smoke, you can take steps to prevent or minimize symptoms.
Common asthma triggers include:
- Indoor allergens: mold, pet dander, dust mites, cockroaches
- Outdoor allergens: pollen, mold
- Irritants: secondhand smoke, diesel exhaust, air pollution
- Respiratory viruses: colds, flu, sinus infections
- Cold air or sudden changes in temperature
- Strong smells
- Strong emotions such as laughing or crying
- Hormonal changes
Does humidity affect asthma?
Yes, humidity in the air can affect people with asthma. Humidity contains moisture that makes the air heavier and denser, making it harder for people with asthma to breathe. Humidity can activate sensory nerve fibers in the airways, causing them to narrow. This can cause coughing, wheezing and shortness of breath. Humidity also causes the air to be stagnant. This creates an environment where air pollutants and allergens such as pollen and mold linger in the air — and potentially lead to an asthma flare.
How to manage your asthma when outdoor humidity is high
- Don’t go outside on hot, humid days.
- If you must go outside, consider going in the late afternoon or early evening when it’s usually less humid.
- Check pollen counts and air quality before you go.
- Make sure you bring a quick-relief inhaler and keep a water bottle for hydration.
How to manage your asthma when indoor humidity is high
- Aim for between 35% and 50% household humidity. Too much humidity makes your home a playground for mold and dust mites.
- Keep bacteria and mold in check by installing a dehumidifier and cleaning it regularly.
Talking About the Weather
What's the spring allergy outlook where you live? Will sudden temperature changes trigger an asthma flare? Weather can play a key role in asthma and allergy symptoms and flu transmission. We partnered with Weather Trends International to provide weather forecasting and analysis for people with asthma and allergies.
What are the symptoms of an asthma attack?
If your asthma symptoms are worsening you could be having an asthma attack, also known as an asthma flare. Any of these signs indicate the need for immediate medical treatment; follow your Asthma Action Plan.

What’s the first thing to do when asthma symptoms begin?
The moment you first notice symptoms use your prescribed quick-relief inhaler containing albuterol or levalbuterol medicine. This medication will relax the muscles that surround the airways, making it easier to breathe within a few short minutes. Use your quick-relief inhaler at the first sign of symptoms or before exercise to prevent symptoms from getting out of control.
How do I monitor my daily asthma symptoms?
National asthma guidelines suggest using a daily symptom diary such as Allergy & Asthma Network’s AsthmaTracker™ to keep track of symptoms, peak expiratory flow rates (if you or your child use a peak flow meter) and medications used.
What is an AsthmaTracker?
The AsthmaTracker™ can help your track how well your symptoms respond to your treatment plan. By writing down your symptoms, peak expiratory flow rate and medication use each day, you’ll notice a pattern to your symptoms and develop strategies to stop the symptoms before they can stop you.
What is a peak flow meter?
A peak flow meter is a handheld device that measures the peak expiratory flow rate (PEFR), or how much air you can forcibly push out of your lungs at a particular time.
