There is a drive for integration of protection against various threats into single materials, in view of the bulk and weight of the clothing. Integrated materials are shown, but relatively few. Thermal sensation for clothed persons is more complicated than for nude. The use of psychological methods is indicated, but better progress is waiting for implementation of these methods on a larger scale. One good example is shown.
Few papers deal with heat acclimatization.
However, some papers deal with the still debatable effects of cold acclimatization. The discussion of the importance of counter-current heat exchange for heat conservation keeps going on. Effectivity of CC heat exchange seems difficult to define. Stroke volume is proposed as a criterion value for heat and exercise tolerance, superior to heart rate or core temperature. There is a renewed interest in the calculation of body heat content in cold conditions.
