This, in turn, obstructs the passage of air and can bring on an asthma attack. Trigger factors can include allergy to house dust mites, pollens or moulds, as well as infections and air pollutants like cigarette smoke and other fumes. Cold air, sudden temperature change, exercise, emotional stress, excitement, medicines and food additives may also trigger asthma in some people. Self Care pharmacists suggest that identifying what triggers your asthma will also help you manage it. For example, dust mite allergy can be avoided by using special pillow and mattress covers and bedding should be washed in hot water and aired regularly in the sun.
Carpets can harbour a lot of dust so rugs that can be cleaned regularly are a better option.
These are relievers and preventers. Relievers help by opening the breathing tubes and by relaxing the tightened muscle during an attack. They should be used only during an attack or to treat wheeziness. Preventer medicines are more important in asthma because they reduce the swelling and mucus build-up in the breathing tubes and prevent muscles tightening around them. Many people successfully balance the use of their preventer and reliever medicines by using an action plan which can be prepared with the help of their doctor or pharmacist.
