Some of us may wonder why exercise induces asthma.
Well, usually during exercise, people like to breathe through the mouth, therefore the air which is coming to the lung is drier and colder. While in normal breathing through the nose, the air is first warmed and moistened by the nasal passages. The sudden change of air humidity and temperature result in exercise induced asthma which is narrowing of the airways.
The Exercise induced asthma Symptoms
The symptoms emerge when the airways getting narrow during physical exercise. For further understanding about exercise induced asthma symptoms, there are several points of the symptoms.
- Short breath – similar to other asthma, exercise induced asthma also result in short breath due to the narrowing airways.

- Pharynx – notice if there are any mucus and cobbles.
- Nose, sinuses, lungs and heart – notice for any abnormalities function.
For people with exercise induced asthma, it is usually diagnosed through the laboratory examination. A series of clinical examination can be done to diagnose exercise induced asthma such as laboratory studies, challenge testing which is used for formalizing the previous diagnose, imaging studies, and finally procedure if needed.
People with exercise induced asthma do not need to restrict their physical activity; they only need to choose the suitable exercise for them. Activities which require a long period of breathing such as football, marathon, basketball, hockey, and many other may be less tolerated.
