Exposure to an antigenic or nonantigenic stimulus

Exposure to an antigenic stimulus or nonantigenic stimulus can aggravate asthma.  Many of these stimuli (particularly nonantigenic stimuli) are very common events which everybody experiences, however, it is only necessary to examine the events which occurred in the 24 hours preceding a permanent aggravation of asthma.
