| dc.description.abstract | Skin temperature is said to be one of the indices useful for estimating thermal environments. The skin temperature, which is closely related to the thermal sensation, is a physiological value regulated by both the conditions of man and his working environment. Mean skin temperature is an important physiological parameter reflecting the human response to heat. For India, very few researchers have developed the mean skin temperature calculation model for Indian subjects, and they have developed the model for general population. There is no specific mean skin temperature model available for farm workers in general and farm women in particular though play the major role in Indian agriculture. The mean skin temperature is the key parameter for measuring the heat stress while working in the agricultural field. The mean skin temperature model development is necessary for Indian farm women for assessing the heat stress. Keeping this in view the research work was conducted on Indian farm women workers to develop the mean skin temperature model by considering the Indian farm women data. The attempt was made to develop the mean skin temperature model with fewer points which gives the best estimation of mean skin temperature. Environmental chamber was prepared for measurement of skin temperature in controlled environmental condition. Twelve female subjects and the thirty two skin temperature measurement sites were selected for assessment of environmental heat on skin temperature. The response of skin temperature site with increase in WBGT was observed. Some skin sites like thigh and abdomen showed the drop in skin temperature with the increase in WBGT. The higher fat content of the thigh and abdomen provides the cooling effect by sweating with increase in WBGT. Forehead showed the drop in skin temperature with the increase in WBGT. Flat body surfaces showed the lower fat content and lower cooling effect with increase in temperature. With increase in temperature, certain body sites of human body like thigh, abdomen and forehead allows sweating to maintain the proper thermoregulation of the human body. Evaluation of selected eight existing mean skin temperature models in Indian conditions were carried out in controlled environmental conditions of temperature and humidity. The selected models were evaluated statistically. The Hardy DuBois seven point model was found best for the Indian farm women. Body sites for the development of the mean skin temperature model were selected on the basis of weightages i.e. the body site having higher percentages of total body weight and thermal susceptibility. Body sites of left upper chest, forehead, right anterior calf, right forearm, and right posterior thigh were selected for the development of mean skin temperature model. Validation of developed mean skin temperature model was carried out in controlled environmental chamber at simulated WBGT conditions. The developed mean skin temperature model was validated with the reference mean skin temperature model. By analyzing the data statistically, significant results were obtained between the developed and reference mean skin temperature model. Linear regression was observed with higher degree of R2 between the developed mean skin temperature model and reference mean skin temperature model. Evaluation of developed mean skin temperature model was carried out in open field conditions while subject performing the farm operations. Mean skin temperature was calculated by the developed five point mean skin temperature model. The skin temperature was recorded for the skin sites forehead, right anterior thigh, right forearm, and left upper chest by the selected sites from developed mean skin temperature model. Eight female subjects were selected for the study. Mean skin temperature was recorded for the subjects while subjects performing the field operations like harvesting of green peas and harvesting of carrots at CTAE farm. | |
