Effect of respiratory exercises on asthma. The Pink City lung exerciser.
Twelve subjects with mild asthmatic episodes in the form of nocturnal precipitation were studied. A two-week schedule of placebo administration, pranayamic breathing exercises using a Pink City lung exerciser alone, and exercises using the lung exerciser with hot, humid air were performed. Five of the 12 asthmatics showed highly significant increases in peak expiratory flow rate (PEFR) with the lung exerciser alone, while eight of the 12 cases showed highly significant increases in PEFR with exercise using hot, humid air. The frequency of nocturnal wheezing also declined. It can be inferred that slow breathing alone and in combination with hot, humid air has a nonspecific bronchoprotective or bronchorelaxing effect.
