Impacts on soldiers' work efficiency at high altitude

Harsh plateau environment, including hypobaric hypoxia, low temperature, solar radiation and high ultraviolet intensity, exerts great influences on soldier's neuropsychological functions and physiological functions. China's evaluation on plateau soldier's performance mainly focuses on the valuation of physical ability. Comparatively, few attentions is paid on the changes of individual neuropsychological functions, which refer to the changes of soldiers' emotion, psychological activity, and cognitive functions, including perception, memory, thinking ability and attention. Therefore, when setting the criterion to evaluate the performance of plateau soldiers, impacts from both neuropsychological and physical elements should be involved.
