[Optimal air conditioning in the classrooms of secondary schools as a factor of improving health status of schoolchildren].

Proceeding from the analysis and statistical processing of the data derived during the study of health dynamics of junior schoolchildren, who studied during an academic year under the conditions of different air exchange regimes (20 and 40 m3 of air per hr/child), it was established that indoor air medium formed by air supply of 40 m3 per hr/child (compared to 20 m3) even during a year had a favorable impact on the functional state of some body systems and prevalence of acute diseases among schoolchildren.
