A study of a practical work-rest regimen in cold storage workers at-15 celsius
Abstract:
The objective of this study was to investigate the effect of differences of work - rest regimen on the physiological responses of eight workers in cold storage facilities (-15 Celsius). The measured parameters were the estimated body temperature, heart rate and subjective feeling of skin temperature. There were five work patterns of work - rest regimen, in which the duration of work and rest were equal. The five work-rest regimens were 20, 25,30, 35 and 40 minutes each. The results showed that the difference of estimated body temperature and heart rate between working and resting and cold subjective feeling of skin of the all work patterns were significantly different (P < 0.001). The first work pattern, working and resting for 20 minutes, had the least difference of those physiological responses. This study suggests that working and resting for 20 minutes is the practical work-rest regimen for cold storage workers to prevent health problems and accidents"
