Asthma refers to an inflammatory condition of the lung, that can affect the entire airway between the lungs and the nose. When this airway becomes swollen, it gets constricted and automatically less air manages to reach the lungs. This is why the person may experience coughing, wheezing, difficulty in breathing, and tightness in the chest.

There are some common environmental triggers of asthma and when you are exposed to such triggers, you can get an asthma attack. However, triggers that you are susceptible to may not be the same as those which cause someone else to get an asthma attack. Once you know what the common environmental triggers of asthma are, you can avoid these to stay healthy.

Following are the common environmental triggers of asthma:

Tobacco smoke
This is unhealthy for all, and especially for people diagnosed with asthma. Even if you do not smoke but stay in close proximity with someone who does, it can trigger an asthma attack.

Dust mites
These are one of the most common environmental triggers of asthma and you will find these in all homes. To prevent attacks from dust mites you must use pillow covers and mattress covers to create a barrier between these and yourself. Avoid using comforters and quilts; keep stuffed toys and clutter away.

Outdoor pollution
Air pollution is known to be one of the key triggers for an asthma attack. This pollution is because of the unhealthy air emission from factories, vehicles, and various other sources.

Mold
When you breathe this in, it may trigger an asthma attack. The only way to avoid this is to make sure your home if free from it. Mold typically grows when there is excess humidity. So, you may use a dehumidifier or air-conditioner to keep humidity levels in check.

Smoke from grass or burning wood
This is composed of small particles and harmful gases. Breathing in such smoke may trigger asthma attacks; so, it is best to avoid burning wood inside. In case there is wildfire outside, you must take note of the air quality and act accordingly.

Formaldehyde
Many home furnishings and building materials are made from this but it can trigger asthma attacks in children and infants. Even cleaning substances like ammonia and chloride can trigger attacks.

Traffic pollutants
When you are highly exposed to motor traffic emission your respiratory functions can be affected. Studies show that young kids living near heavy-traffic roadways have higher rates of diagnosed asthma and wheezing.

Occupational asthma
This refers to a limitation in airflow because of conditions relating to a specific occupational environment. Such diseases will occur on exposure to high doses of any workplace irritant. For instance, the RADS or reactive airway dysfunction syndrome that happens because of exposure to very high levels of fume, vapor, and smoke.

Pollens
Allergenic pollens are very small and can be transported through winds. This may induce rhinoconjunctivitis in people who are allergic to pollens.

Meteorological changes
When the daily temperature goes up asthma cases go up too, particularly in elderly people. Even severe cold temperatures can trigger attacks.
