[Characteristics of the human thermal state and environment in long-term space flight].

Summarized are data of many-year studies of thermal loading and thermal state of humans in different microclimates. Comparative analysis of various approaches to thermal monitoring of cosmonauts in space suits was performed with the conclusion about advantages of parotid thermometry. To set microclimate standards for long-term space flight, a complex index of the environment cooling potential (ECP) based on the use of an electrical dynamic catathermometer has been proposed. A correlation between ECP values and cosmonaut's thermal sensations was elicited. For the most part, the proposed recommendations have been verified or introduced in the space crew medical care system.
