We studied the effect of academic studies with the use a notebook computer and interactive whiteboard on the functional state of an organism of schoolchildren. Using a complex of hygienic and physiological methods of the study we established that regulation of the computer activity of students must take into account not only duration but its intensity either. Design features of a notebook computer were shown both to impede keeping the optimal working posture in primary school children and increase the risk offormation of disorders of vision and musculoskeletal system.

For realization this method an algorithm of computer program was developed for processing hundred thousands of points of skin temperature measures and temperature of surrounding environment. This method can be used for assessment of big groups of population.

The paper deals with the role of individual grading of heat loading when preschool children take a sauna. The adaptative reserves of the child's body were determined by thermal imaging just during exposure in the thermal chamber. The time course of the maximum skin temperature, which was determined by a thermal imaging computer, was used as an informative indicator.
