Asthma is a condition in which the airways narrow and swell, making it difficult to breathe and triggering coughing, wheezing, and shortness of breath. The exact cause of asthma is unknown, but it is believed to be due to a combination of environmental and genetic factors. Some of the factors that can increase a persons risk of developing asthma include:

• Having a parent with asthma
• Having a severe respiratory infection as a child
• Having an allergic condition
• Being exposed to certain chemical irritants in the workplace
• Being exposed to certain dusts, chemical fumes, and molds
• Being overweight or obese

Asthma can also be triggered by a variety of factors, including:

• Allergies to substances such as pollen, dust mites, animal fur, or feathers
• Air pollution, including smoke, fumes, and ozone
• Respiratory infections such as colds, flu, and sinus infections
• Exercise, especially in cold air
• Emotional stress
• Certain medications
• Weather changes, such as thunderstorms or high humidity

It is important to note that asthma triggers can vary from person to person, and some people may react to only a few while others react to many. Avoiding triggers and following an asthma action plan can help manage symptoms and prevent asthma attacks.
