Abstract
We studied the influence of atmosphere on the frequency of sneezing in 450 patients for 15 months (from Feb. 1978 to May 1979).
The frequency of sneezing had the closest relation with change of temperature in early spring and early autumn, particularly with day-difference of highest and lowest temperature.
Other conditions such as air pressure, humidity, wind velocity, weather, daylight-hours, etc. had little to do with it.
The allergen test suggested that the number of patients with pollinosis caused by Ambrosia elator would be largest in August and September, but it turned out that the actual number was doubled in February, March and April.
