摘要

Introduction: Workers who are working in various industries are at increased risk of heat related illnesses. They experience an additional heat load on the body from their work environment apart from the external environmental temperature. Heat stress is one of the important risk factor affecting workers health at work place which leads to severe health impairments.Aim: To assess the heat stress and heat strain among residential complex maintenance workers in Chennai.Materials & Methods: Area Heat stress assessments were measured using Quest Temp Wet Bulb Globe Temperature (WBGT) monitor. Questionnaire was administered to procure information about occupational heat exposure, personal history, and medical history of the subjects. Core body temperature and heart rate was collected before the start of work (Pre) and 2 hours after the work (post). Sweat rate was calculated using Canadian sports association formula. An intervention study (nutritional) was conducted in a subset of population.Results: Area heat stress measurements (WBGT) ranged from 24.7°C to 30.2°C. 90% of the workers gave history of excessive sweating during work in hot environments and 78% of the workers gave history of excessive thirst. There was a significant increase in core body temperature and heart rate during the post work session compared to the pre work measurement (P value < 0.05). About 58.8% of the workers had high sweat rate.Discussion & Conclusion: This study has demonstrated statistically significant increase in body temperature, heart rate and sweat rate after work in excessive heat stress conditions. This study indicates that heat exposure is perceived as a significant problem by the workers affecting both physical and mental health.
