The temperature of the air environment of industrial premises as a harmful factor in working conditions

This article is devoted to examining the importance of ensuring the optimum temperature in a production environment to humans.Human activity can normally occur only under condition of preservation of temperature homeostasis of the organism, which is achieved through the system of thermoregulation and activity of other functional systems: cardiovascular, excretory, and endocrine systems that provide energy, water-salt and protein metabolism. The average human body temperature usually ranges between of 36.5 and 37.2 degrees Celsius (°C). due to the internal exothermic reactions and the presence of "safety valves" that allow to remove excess heat sweating. For a person in light clothing will be comfortable air temperature + 20º 19...With no clothes + 28...31° C. To maintain a constant body temperature the body must be in a thermostable state, which is estimated by heat balance. Heat balance is achieved by coordinated processes of heat production and heat loss. The human health, its performance is largely dependent on the climate in the workplace. The microclimate parameters have a direct influence on the thermal state of a person and determine his health. Prolonged human exposure to adverse temperatures climate sharply deteriorates his health, reduces productivity and can lead to various diseases.
