When you know how to control asthma, it no longer controls you. Asthma is a lung disease. It can be life threatening. Asthma is chronic. In other words, you live with it every day.
Asthma causes breathing problems.
Controlling your exposure to triggers outdoors is hard. You may have to avoid outdoor air pollution, pollen, and mold spores. The air at home is easier to control. Some people with asthma and allergies notice that their symptoms get worse at night. Trigger controls in the bedroom, or wherever you sleep, need the most care.
