Введение. Связь между температурой кожи и кожным кровотоком является фактором, влияющим на тепловые изображения организма в ответ на терморегуляцию.Цель. Выявление особенностей тепловых изображений юношей – постоянных жителей Севера, относящихся к различным поколениям.Материалы и методы. Термография проводилась с использованием тепловизионной камеры (тепловизор FLIR SC620, Швеция). Количественный анализ тепловизионных изображений был выполнен для 8 частей тела, снятых спереди и сзади в положении сидя. Было обследовано 90 молодых здоровых людей в возрасте от 17 до 21 года, постоянно проживающих на территории Магаданской области. В зависимости от продолжительности адаптации к условиям Севера все испытуемые были разделены на 4 группы: адаптирующиеся мигранты («нулевое поколение») и родившиеся на Севере в 1-м, 2-м и 3-м поколениях.Результаты. Показано, что в ряду от мигрантов-адаптантов («нулевое поколение») к уроженцам Севера в 1-м, 2-м и 3-м поколениях происходит значимое увеличение температуры поверхности кожи по всем изученным областям теплового портрета. При этом максимальные различия наблюдались в отношении средней температуры лба, живота и поясницы, достигая 0,97; 1,04; 0,98 °С соответственно. Следует отметить, что юноши Магадана характеризовались более высокой средней температурой поверхности кожи по сравнению с юношами, проживающими в оптимальных климатических и географических условиях Центральной России и Восточной Европы. Наименьшие отличия фиксировались между мигрантами-адаптантами и лицами 3-го поколения в отношении температуры груди – 0,43 °С.Выводы. Проведенное исследование указывает на тот факт, что с увеличением сроков проживания на Севере в организме происходят компенсаторно-приспособительные перестройки, которые направлены на уменьшение негативного влияния холодового фактора и достигаются за счет оптимизации терморегуляторного механизма, а также изменения вегетативных кожных вазомоторных реакций.

Introduction. The correlation between skin temperature and cutaneous blood flow is a factor that influences thermal imaging of the body in response to thermoregulation. The objective of our study was to identify features of thermal images of young male permanent residents of the Russian North belonging to different generations. Materials and methods. Thermography was carried out using a thermal imaging camera (FLIR SC620 thermal imager, Sweden), providing long-wave (7.5–13 μm) imaging with a thermal sensitivity of 0.1 °С. Quantitative analysis of thermovision images was performed for eight sites of the body captured from the front and back in a sitting position. We examined 90 young healthy men aged 17 to 21 years, permanently residing in the Magadan Region. Depending on the duration of adaptation to extreme conditions of the North, all subjects were divided into four groups: adapting migrants (“zero generation”) and those born in the North in the first, second and third generations. Results. We established a significant increase in skin temperature at all measured body sites in the series from adapting migrants (“zero generation”) to the natives in the first to third generation. The maximum differences were observed for the average temperature of the forehead, abdomen, and lower back, reaching 0.97, 1.04, and 0.98 °C, respectively. It should be noted that the young men of the city of Magadan had a higher average skin temperature than those living in optimal climatic and geographical conditions of Central Russia and Eastern Europe. The smallest difference (0.43 °С) was registered for breast temperature between the migrants and representatives of the third generation. Conclusions. Our findings prove compensatory and adaptive physiological changes occurring in the body over time to reduce adverse effects of the cold environment. This reorganization of the body is achieved through optimization of the thermoregulatory mechanism and changes in vegetative skin vasomotor responses.
