There are many triggers for asthma. Sa atong climate karon, sudden changes of temperature can tigger an attack. Like being out in the hot weather then suddenly mosulod mo og very cold na place like that in the malls or offices. Ok lang if inanay you give your body time to adjust. Colds caused by dust, virus or dryness of the nasal lining may trigger an attack since the mucus will drip down to the tutunlan then to the passage of air. In asthmatics, they have hypersensitive linings in the air passages from the throat area to the lungs. In other words,once motulo na ang mucus sa passage moreact dayon ang lining sa passages then an attack happens. Better thing to do, once magsip.on na gani talk to your friendly neighborhood doctor or blow that mucus out.
Hope this helps.
