Hello If asthma is exercise induced please stop or reduce the intensity of exercise and consult a CARDIOLOGIST because usually exertion induced asthma is known as CARDIAC ASTHMA . But if it is allergic need not to worry ,in this type of asthma patient usually develop wheezing ,sneezing , whistling sound during inhalation or exhalation ( usually this is due to bronchoconstriction and when such type of patient visit I advise my patient to take montelukast + bambuterol tablet one or two in day and patient respond this treatment very well. Also avoid fine dusting powder, mold, pollen , pests ( cockroaches ) , sudden change of temperature , fodder , fumes , smoking spray as these are predisposing factor of allergic asthma. Hot coffee and steam inhalation also provide relief. Respiratory naturally help in allergic asthma ( until and unless not indicated ). Hope this will help you.
