[Individual typological characteristics of the cardiovascular reaction to partial body cooling in workers on field-watch assignments].

Due to the use of a cluster analysis 5 types of the individual cardiovascular response to hand local cooling and of cold thermosensitivity were identified. The following groups were determined: I. non-cold-adapted group with elevated cold thermosensitivity and vascular response to local cooling, young age and short-term length of service on watch; 2. the group with different levels of thermal adaptation on the verge of the 3-year period of work, the age being similar; 3. the group with extremely low cold thermosensitivity and moderate vascular response to local cold. The group is characterized by long-term length of service and positive forecast as to individual work under subextreme conditions of being on dispatch watch.
