background: work clothing can limit heat exchange between humans and the environment and cause thermal strain and heat-related disorders in workers. it can thus reduce both efficiency and productivity. the purpose of this study was to examine the effects of work clothing material on physiological strain index (psi) in climatic chamber. methods: an interventional study was conducted on 18 male s...

conclusions the mean heart rate was higher in participants who were overweight than those with normal weight. results the mean and standard deviation of the heart rate in the hot climatic condition and moderate exercise were 103.84 (3.34) for normal weight subjects and 108.67 (3.27) for overweight subjects. the mean and standard deviation of the heart rate in a very hot climatic condition and l...

Drawing on the hot-cool systems analysis of self-regulation, we examined whether attentionalfocus mediates the negativity of cognitive-affective reactions to interpersonal rejection. The hypothesis was that whereas a hot, arousing focus to representing rejection experiences should increase anger-hostility, accessing the cool system through distraction and distancing should attenuate such respon...

The aim of this study was to investigate the effects of heat exposure in the absence of hyperthermia on power output during repeated cycling sprints. Seven males performed four 10-s cycling sprints interspersed by 30 s of active recovery on a cycle ergometer in hot-dry and thermoneutral environments. Changes in rectal temperature were similar under the two ambient conditions. The mean 2-s power...

Hot working condition is the integration result among temperature, humidity, velocity of air movement, and hot radiation from the body's workers, which causes the decrease of systol-icblood pressure withits complication (1). The kitchen is a place with hot working condition because there is process of cooking using the instruments producing hot radiation making the space of kitchen to be hot. A...
