Hygienic examination of the stimulating effect on the organism of a complex of natural substances.
No exhaustive hygienic studies have been conducted yet of the natural substances present in the atmosphere. A complex of natural substances was shown to affect EEG parameters, subjective perception of one's health and general perception. The concentration of the vapours of a mixture of substances was kept at 0.1 mg/m3 which is characteristic of mountainous air. The inhalation of the natural substances was shown to alter the EEG indicators and subjective perception of tested subjects, suggesting a stimulatory effect on the central nervous system. The natural substances proved to stimulate the efficiency of mental and manual work, self-perception and mood. These effects can be accounted for by the positive biological influence of the mountainous atmosphere.
