What Causes Asthma?

Asthma is caused by a variety of both inherited and environmental factors. Since asthma affects everyone differently, there are many different triggers, which can result in symptoms of asthma. Allergens and other irritants present in the environment, which can result in asthmatic symptoms include smoke, pollen, dander, mold and dust mites. Other causes of asthma include exposure to cold air, stress and infections of the respiratory system including the common cold. Since genes also play a role in the cause of asthma, atopy, or a genetic predisposition towards developing allergies, can also cause symptoms of asthma.

How Can Asthma Attacks Be Prevented?

Asthma attacks can be prevented by avoiding or limiting exposure to what triggers asthmatic symptoms. Since common irritants such as smoke, dust, pollen, dander and mold have been known to result in symptoms of asthma; a person should know if they are hypersensitive to any of these irritants and avoid exposure to them as much as possible. Asthma symptoms can also be worsened by respiratory infections such as the flu or a cold, so special precautions should be taken to avoid sickness. If asthma symptoms are brought on by exercise, these symptoms can be abated by using an asthma inhaler.
