The influence of indoor plants on the microclimate of classrooms and the health of students
Purpose: The formation of knowledge about the health and influence of indoor plants on it.
1) Give a definition of the term microclimate and designate its optimal conditions for the health of the human body.
2) Tell about the effect of plants on the human body.
3) To tell about the effect of plants on the microclimate of the premises.
The microclimate is a complex of physical factors of the indoor environment that affects the heat exchange of the body and human health. Microclimatic indicators include temperature, humidity and air velocity, surface temperature of building envelopes, objects, equipment, as well as some of their derivatives (air temperature gradient along the vertical and horizontal premises, the intensity of thermal radiation from internal surfaces).
Optimal microclimatic conditions are such a combination of microclimate parameters that, with prolonged and systematic exposure to humans, provides a feeling of thermal comfort and creates the prerequisites for high performance.
Permissible microclimatic conditions are such combinations of microclimate parameters that, with prolonged and systematic exposure to humans, can cause stress of thermoregulation reactions and which do not go beyond physiological adaptive capabilities. In this case, there are no disturbances in the state of health, there are no uncomfortable heat sensations that worsen well-being and a decrease in working capacity. Optimum microclimate parameters in the premises are provided by air conditioning systems, and acceptable parameters are provided by conventional ventilation and heating systems.
Currently, scientists have established that in addition to aesthetic properties, plants have another useful function - indoor plants improve the composition of the air, clean the atmosphere, which has a beneficial effect on our well-being brain activity.
The air environment of city apartments and, in particular, study rooms is far from ideal. In addition to ordinary dust, often the indoor air has a high content of chemical compounds produced by building materials and furniture.
In addition, the air environment contains opportunistic microorganisms, such as staphylococcus, microscopic mold fungi. These organisms, falling into favorable conditions on the mucous membranes of the upper respiratory tract, can cause acute respiratory and allergic diseases. Plants, on the other hand, often serve as filters for harmful substances, being detoxifiers and air ionizers.
It is necessary to study in detail indoor plants and their impact on our health. And among all their diversity, there are those that cleanse the air of toxins, and, consequently, improve the indoor climate.
All indoor plants can be divided into several groups according to various characteristics:
? Decorative leaf
They are an integral part of the interior. As a rule, they bloom in small and non-decorative flowers. They are grown because of their beautiful leaves, usually green or other unusual colors: yellow, red, some plants have leaves that change color in autumn. Leaf shapes are: lobed, dissected, linear, oval, etc. Most leaf blades have serrated edges.
This most extensive group of indoor plants is rightfully considered the most valuable for growing in rooms. Some plants form berries and fruits. Plants bloom at different times of the year, some all year round. The duration of flowering of each species ranges from several days to several months. Among the many flowering plants, there are annuals that fade after the first flowering.
2) Effect on the human body
Do not have a pronounced effect on a person.
3. Harmful (poisonous)
They have a negative effect. Touching, eating or inhaling the smell of these plants can lead to a general deterioration in well-being, allergic reactions, etc.

When controlling the state of the microclimate in rooms for animals, the physical properties of air (temperature, humidity, speed and cooling properties of air, atmospheric pressure, illumination, ionic background and noise level) are determined; gas composition (concentration of carbon dioxide, ammonia, hydrogen sulfide, carbon monoxide); quantity and quality of suspended solids in the air (dust and
- The effect of physical and chemical parameters of air on human health and hygiene requirements for the air-thermal regime of school premises
Optimal air conditions are an important factor in maintaining human health and performance. Adverse changes in the air can cause significant disturbances in the body: overheating or hypothermia of the body, hypoxia, the occurrence of infectious and other diseases, and decreased performance. In a comprehensive hygienic assessment of air, the following are taken into account: - physical
