“…The finding showed that body temperature, respiratory rate, and weather temperature were statistically significant between three seasons. Heat stress occurs when the human body is not able to dissipate sufficient excess metabolic heat, leading to an increase in body temperature and heart rate [23,24] with WBGT increment up to 28-30°C [25]. The farmworkers had more abnormal results of clinical assessment occurring in summer than the rainy season and winter.…”

Background. Thailand is a tropical developing country which has a serious increase in health risk due to hot weather exposure among outdoor workers. Objectives. The aims of this study were to compare the factors related to environmental heat exposure in three different seasons, and to assess the relationship between environmental heat and dehydration status in each season among farmworkers in Nakhon Ratchasima, Thailand. Methods. A semi-longitudinal study was carried out in 22 male farmworkers throughout a year of farming. The primary data were collected in farmworkers for socio-demographic information, clinical assessments, and heat-related illnesses. Results. Average of environmental heat index (Median, SD) were severe in summer (WBGT=38.1, 2.8°C), rainy season (WBGT=36.1, 2.1°C), and winter (WBGT=31.5, 2.7°C). Average urine Sp. Gr. in summer, rainy season, and winter were 1.022, 1.020, and 1.018 respectively. The third sentence should be corrected as follows: The Friedman analysis revealed a statistically significant difference between the three different seasons in WBGT (wet bulb globe temperature), body temperature, heart rate (P<0.01), and respiratory rate (P<0.05). There was a statistically significant difference between the three different seasons for skin rash/itching, dizziness, muscle cramp dyspnea (P<0.05), and weakness (P<0.01). Wilcoxon signed-ranks analysis found a significant difference in the medians of the paired sets of urine Sp. Gr. values between baseline and summer (P<0.05). Spearman's rank correlation coefficient did not find a relationship between WBGT and urine Sp. Gr. in the three different seasons. Conclusions. This study demonstrated that farmworkers had exposure to environmental heat stress which was expressed through physical changes. Therefore, there is a need for either interventions or guidelines to prevent dehydration for outdoor workers in this region.

“…Hence, to evaluate the effect of heat stress, mean skin temperature and aural temperature were found better parameters to be measured in combination of WBGT. Kashyap et al, (2017) measured oral temperature, mean skin temperature and heart rate to evaluate the effect of environmental heat on farm workers. With the increment of WBGT from 28 to 30ºC, all these physiological parameters had raised.…”

“…More water consumption should also be encouraged by the agricultural workers in hot environment. Lam et al, (2013) recommended strategies for heat related illness prevention which included health promotion, use of personal protective equipment, administrative and engineering strategies. Tjasa et al, (2017) found in their research that more water intake, rest periods at cooler places and wearing light clothing were counter measures to prevent heat related illness.…”

Heart rate and mean skin temperature (MST) are the physiological workload and overall discomfort rate (ODR), Rating of Perceived Exertion (RPE) is the physical workload due to heat stress. The whole study was conducted during the manual harvesting of wheat crop by using local sickle at instructional Farm, CTAE, Udaipur. The study was conducted on ten female farm workers identified from the population of workers in the age bracket of 18 to 45 years. The chosen workers were wearing their usual outfits during the whole operation. Mean skin temperature measurement is necessary to assess the thermal comfort of the farm workers. Experiments were conducted to evaluate the mean skin temperature of Indian farm women. Therefore, the experiment was designed for five WBGT conditions i.e. 28, 29, 30, 31 and 32°C which falls under the category of heat stress given in norms of ACGIH. A variation of ± 0.5°C was assumed in the open field conditions, as it is very difficult to achieve exact thermal conditions i.e., WBGT conditions in the open field.
