Research on Physiological Adjustments of Textile Workers

To investigate the physiological adjustments of textile workers exposed to high temperature environment, 10 workers with years of work experience and 12 students with rarely entering into workshop were chose to a hospital for blood test and nerve conduction velocity measurements. The blood test was to measure potassium content, sodium content, calcium content and bicarbonate content in participant’s blood. Nerve conduction velocity was measured by EMG / Evoked Potentials to analyze motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV). MNCV and SNCV were measured through stimulating the median nerves of right hand, in an attempt to estimate the influence of thermal experience. Different from previous literature, potassium, sodium, calcium and bicarbonate content in the blood were basically similar to the worker and student, all within normal range. Similarly, MNCV and SNCV weren’t significantly different for workers and students, which mean that different thermal environment or thermal experience can’t significantly affect SNCV and MNCV of subjects.
