Impact of Variation in Thermal Working Environmental Condition on Cardiac Response Indices in Male Human Resources Engaged in Food Crop Cultivation Task

Climate change poses a serious threat worldwide including increase in temperature particularly in tropical countries and our country India is no exception to it. It has been also reported that the work performance of the human resources is also affected particularly those who were exposed to outdoor working environment. In this backdrop, the present study has been undertaken to assess the physiological strain in male food crop cultivators (age range 24-36 years) occupationally engaged in reaping tasks during food crop cultivation. Physical and physiological parameters are also recorded. Indicators of thermal environmental condition i.e. dry bulb temperature, and wet bulb temperature are also recorded during the working time. Results of the present study indicated unfavourable working environmental condition making the task more arduous for the human resources engaged in reaping task during ‘Boro’ type of paddy cultivation time as indicated from the indices of physiological strain.
