intrinsic asthma, a nonseasonal, nonallergic form of asthma, which usually first occurs later in life than allergic asthma and tends to be chronic and persistent rather than episodic. Precipitating factors include inhalation of irritating pollutants, such as dust particles, smoke, aerosols, strong cooking odors, and paint fumes and other volatile substances. Intrinsic asthma may also be triggered by exposure to cold, damp weather; sudden inhalation of cold, dry air; physical exercise; violent coughing or laughing; respiratory infections, such as the common cold; or psychologic factors, such as anxiety.
