Abstract
Introduction: Continuous exposure to cold air is considered a hazardous agent in the workplace in cold seasons. This study aimed to determine the level of cold strain and its relation with physiological responses in auto mechanic employees in cold seasons.
Method: This cross-sectional study was conducted in winter of 2017 on auto mechanic employees in Hamadan City. Selection and sampling method was done randomly. A study was conducted on 50 workers. Physiological responses during daily activities were measured in accordance with ISO 9886 standard method. Based on the results of measuring core and skin temperatures, cold strain index was determined. Sensorineural test to determine the level of numbness in the fingers of workers by monofilament kit was performed. Environmental parameters of air were measured simultaneously. The data were analyzed using SPSS 21 software.
Results: The average index of cold strain score was 4.38 ± 1.788. Results showed that there was a significant relationship between the cold stain index score with physiological responses such as heart rate (r=-0.39, p<0.05) and systolic blood pressure (r=-0.57, p<0.05) and diastolic blood pressure (r=-0.38, p<0.05). By reducing the temperature of dry air, a cold Strain Index value was also increasing(r=-0.93, p<0.05). The results showed that 62% of workers had numbness symptoms in fingers and there was a significant relationship between numbness of fingers with air temperature (r=0.74, p<0.01) and cold strain index(r=0.84, p<0.01).
Conclusion: The cold strain index, with the acceptable reliability, indicates the physiological responses of the workers expose to cold. More than half of the workers had also the numbness symptoms in their fingers that effect on their physical performance at work.
