Dust and Fumes

Dust and fumes found in certain occupations, such as construction, mining, and welding, can exacerbate asthma symptoms. These particles can irritate the airways and lead to airway inflammation. If you work in an occupation with high levels of dust or fumes, it is important to take appropriate measures to protect yourself, such as wearing respiratory protective equipment and ensuring proper ventilation in work areas.

Secondhand Smoke

Secondhand smoke, also known as passive smoking, can be particularly harmful for individuals with asthma. Exposure to secondhand smoke can worsen asthma symptoms and increase the risk of asthma attacks. It is important to avoid areas where smoking is allowed and to ask family members, friends, and visitors to refrain from smoking around you or in your home.

Exercise and Physical Activity

Regular physical activity is important for overall health, but it can also trigger asthma symptoms in some individuals. Exercise-induced asthma is a condition in which physical activity leads to bronchospasm and symptoms such as coughing, wheezing, and shortness of breath. However, with proper management, individuals with exercise-induced asthma can still participate in physical activity. Taking prescribed medications before exercise, warming up before intense exercise, and using proper breathing techniques can help reduce the risk of asthma symptoms during exercise.

Stress and Emotional Factors

Stress and strong emotions can influence asthma symptoms in some individuals.
