ASTHMA TRIGGER –PREVENTION AND CAUSES

Asthma is a condition in which your airways narrow and swells and produce extra
mucus. This can make breathing difficult and trigger coughing, wheezing and
shortness of breath.

For some people, asthma is a minor nuisance. For others, it can be a major
the problem that interferes with daily activities and may lead to a life-threatening
asthma attack.

Asthma can’t be cured, but its symptoms can be controlled. Because asthma often
changes over time, it’s important that you work with your doctor to track your
signs and symptoms and adjust treatment as needed.

Certain asthma triggers can set off a cascade of asthma symptoms. These include:

Air pollution
 Allergies
 Cold air
 A cold or flu virus
 Smoke
 Fragrances

It’s vital to learn to identify your asthma triggers and take steps to avoid them.
People who live in urban areas, where there are more smoke and smog, are more
likely to have asthma. Smog is a darker air pollution that tends to be present in
bigger cities with more vehicles and factories.

Ozone, which is a major component of smog, can trigger asthma symptoms such
as wheezing and shortness of breath.
As well as ozone, smog contains sulfur dioxide, which can irritate the airways and
trigger asthma attacks.

Exposure to firsthand cigarette smoke can irritate the airways and make it more
likely that a person with asthma will have more frequent and severe symptoms.
This is also true for secondhand smoke. Even when people smoke outside the
home or in a car, the lingering smoke and chemicals can expose others to
secondhand smoke.

Allergens such as pet dander and pollen can trigger asthma attacks. People who
have allergy-related conditions such as eczema and allergic rhinitis are more likely
to have asthma.

As a result, avoiding allergic triggers can help prevent asthma reactions.

Allergens that may trigger asthma include:

pet dander
 dust mites
 mold
 pollens

If certain allergens trigger asthma symptoms, avoiding these triggers whenever
possible is vital
