Excessive heat during work creates occupational health risks; it restricts a worker's physical functions and capabilities, work capacity and productivity. Temperatures above 24-26 °C are associated with reduced labour productivity. Exposure to excessive heat levels can lead to heatstroke, sometimes even with a fatal outcome. The aim of this study is to discuss the methodology in experimental of the factor affecting heat stress in industrial workers exposed to extreme heat. The experiment will be conducted in an environmental chamber which simulates the same environment of the manufacturing industry and another arrangement which simulates the environment of a construction industry. The environmental parameters will be recorded such as the temperature, relative humidity and also the physiological parameters such as the volume oxygen uptake level and the heart rate. The heart rate and the volume of oxygen uptake will be recorded for a 15-minute interval for one shift (2 shift-manufacturing and construction). This study is conducted based on two tasks in two different conditions, outdoor and indoor. It simulates the lifting work at both manufacturing and construction industry. For manufacturing industry, the subjects are demanded to lift boxes (10kg). Meanwhile, for the construction industry, the subjects are demanded to lift a sand bag (10kg). From this study, the optimum values of temperature and humidity can be obtained which can lead to the optimum workers' performance. The increase of performance will ensure the production level at the manufacturing industries at its best and will lead to monetary gain. Besides, this can ensure that a construction project can be delivered at the right time while reducing the cost lost and the accidents at the site.

Heat Strain is an acute or chronic impact caused by exposure to heat stress experienced by a person from both physical and mental aspects. Preliminary studies conducted on 20 workers using the HSSI (Heat Strain Score Index) method found that 11 people (55%) did not experience heat strains and 9 people (45%) experienced heat strains. The physical effects of heat strains range from minor complaints such as skin rashes to fainting to life-threatening situations when there is a cessation of sweat and heatstroke. This research was conducted with quantitative research methods with a cross-sectional study design using primary data on 59 workers. Research variables were analyzed using the chi-square test. The results of the bivariate analysis found a relationship between heat stress, age, and hydration status with heat strain. While the variables of obesity and chronic disease have no relationship with heat strain.
The present research designed to find out comparative changes in the physiological parameters in relation to physical work pattern. A total of 800 (200 each group) adult males ranging in age from 30-40 years involved in four different traditional occupational groups i.e. Tailors, Farmers, Carpenters and Blacksmiths were measured for systolic, diastolic blood pressure, pulse rate and maximum expiratory pressure. Findings of the study reveal that Farmers possess maximum systolic (128.4mmHg) and diastolic (86.9mmHg) blood pressure, Tailors and Carpenters maximum pulse rate (78.2 beats/minute) and Blacksmiths possess maximum Maximum Expiratory Pressure (65.98mmHg). Prevalence of hypertension is observed maximum in Farmers in comparison to all the other occupational groups.

Heat Stress Vulnerability among Indian Workmen
Handbook of Research on Climate Change Impact on Health and Environmental Sustainability
The average global temperature increase is estimated to go up by 1.8-4.0 0 C by the next century. This climate change ought to affect populations where the burden of climate-sensitive disease is high-such as the urban poor in low-and middle-income countries. Particularly in industrial applications, heat generates during manufacturing process. This heat transmits to the environment to make it hotter, as well as the community, especially affecting workers involved in the operation. The primary outcomes of working in such environment leads to three kinds of major heat-related disorders-heat cramps, heat exhaustion and heat stroke. Understanding the quantifiable volume of health impacts due to work habits in hot working environment would provide multiple avenues of suitable intervention. Elucidating the multiple avenues of work pattern, physical and physiological attributes would generate knowledgebase and yield numerically defined susceptibility limits of workers occupational front. The present chapter provides directions to research into the heat related health profile of Indian workmen which would ascertain the relative vulnerability of different occupational groups to their workplace heat eventuality.
Occupational Heat Stress Impacts on Health and Productivity in a Steel Industry in Southern India
Background: Workers laboring in steel industries in tropical settings with high ambient temperatures are subjected to thermally stressful environments that can create well-known risks of heat-related illnesses and limit workers' productivity. Methods: A cross-sectional study undertaken in a steel industry in a city nicknamed "Steel City" in Southern India assessed thermal stress by wet bulb globe temperature (WBGT) and level of dehydration from urine color and urine specific gravity. A structured questionnaire captured self-reported heatrelated health symptoms of workers. Results: Some 90% WBGT measurements were higher than recommended threshold limit values (27.2 e41.7 C) for heavy and moderate workloads and radiational heat from processes were very high in blooming-mill/coke-oven (67.6 C globe temperature). Widespread heat-related health concerns were prevalent among workers, including excessive sweating, fatigue, and tiredness reported by 50% workers. Productivity loss was significantly reported high in workers with direct heat exposures compared to those with indirect heat exposures (c 2 ¼ 26.1258, degrees of freedom ¼ 1, p < 0.001). Change in urine color was 7.4 times higher among workers exposed to WBGTs above threshold limit values (TLVs). Conclusion: Preliminary evidence shows that high heat exposures and heavy workload adversely affect the workers' health and reduce their work capacities. Health and productivity risks in developing tropical country work settings can be further aggravated by the predicted temperature rise due to climate change, without appropriate interventions. Apart from industries enhancing welfare facilities and designing control interventions, further physiological studies with a seasonal approach and interventional studies are needed to strengthen evidence for developing comprehensive policies to protect workers employed in high heat industries.
