Features of the management of nutrition in persons working in conditions of a heating microclimate (literature review)

introduction. The article discusses the nutritional features when working in a heating microclimate, including the effect of high temperatures on the physiological functions of the body, energy metabolism, and water-electrolyte balance. Modern scientific data on the role of macro- and micronutrients, as well as strategies for replenishing physiological needs to maintain perfTormance and health are analyzed.

The purpose of the study. To study the physiological needs for nutrients and hydration when working in a heating microclimate and develop recommendations for optimizing the diet to maintain performance and health.

A systematic scientific review of studies in Russian and English was conducted using the information portals eLIBRARY.ru, Science Direct, PubMed, including studies of the effect of high temperatures on the human body, energy metabolism, and water-electrolyte balance. The data from studies conducted at the Federal Scientific Center of Hygiene named after F.F. Erisman on the role of macro- and micronutrients in nutrition in a heating microclimate, as well as hydration strategies, were used. It has been established that in conditions of a heating microclimate, energy metabolism shifts towards carbohydrate metabolism, and the loss of fluid and electrolytes requires increased attention to hydration.

Conclusion. The conducted analysis of literary sources and materials of scientific research conducted at the Federal Scientific Center of Hygiene named after F.F. Erisman allowed substantiating the principles and recommendations for the development of a diet adapted to the conditions of a heating microclimate to maintain an optimal level of hydration and provide the body of workers with the necessary nutrients. The optimal diet should include easily digestible carbohydrates, a moderate amount of protein and fats, as well as vitamins and minerals. Recommendations have been developed for compiling a diet and a nutritional regimen when working in conditions of a heating microclimate.
