[Hygienic evaluation of the effectiveness of short-term suburban recreation from the viewpoint of natural climatic and demographic factors].
The importance of recreation grew considerably with the increase of leisure time and cultural level of the workers. In our country, on the other hand, there are no complete hygienic studies on the problems of organization and necessary equipment for recreation. In that connection, hygienic-urbanization, hygienic-sociological, microclimatic and physiological studies, as well as investigations on ultraviolet radiation, level of noise and extent of air pollution in some typical recreation places (Sofia and Varna) were carried out. Better conditions were established in nature - town ourskirts environment (as regard ultraviolet radiation, noise level, degree of air pollution, temperature-humidity and radiation microclimate) and their favourable effect on the physiological functions of organism (particularly as regards thermoregulation and cardiovascular system). A dependence was also established between the population recreation needs and social-demographic and nature - climatic factors. Tangible recommendations for the improvement of the state of short-term town outskirts recreation in Sofia and Varna are proposed on the base of the results.
