“…They were also informed of the aim and method of the study. If the body temperature reaches more than 38.5 degrees Celsius, the person feels dizzy, nauseous, or weak, or the heart rate reaches the maximum threshold according to Eq (1), the experiments will be stopped [3,37].…”

“…Exposure to warm air conditions in the workplace can directly or indirectly affect employees’ physiological responses, such as body temperature, metabolism rate, heart rate (HR), and blood pressure [ 1 – 3 ]. It can cause heat-related illnesses, including heat exhaustion, muscle cramps, heatstroke, heat rashes, and neuropsychiatric disorders [ 3 – 5 ].…”

“…In addition to the aforementioned environmental and underlying factors, some secondary body physical factors may affect the level of body heat tolerance. The most critical factors include body fat mass, body volume to surface ratio, physical fitness, and maximal aerobic capacity (a cardiopulmonary index of maximal oxygen uptake) [ 1 , 3 , 15 , 16 ]. Maximal aerobic capacity (also known as VO 2 max or peak oxygen uptake) indicates the maximum rate of oxygen transport to the muscles.…”

Workers’ heat tolerance plays a crucial role in maintaining their health and performance in hot environments. This study aimed to empirically analyze the body heat tolerance of workers under a simulated warm environment. Twenty healthy male workers from the typical light metal industry (age: 23.15±2.45 years) were participated in the experimental study. Workers were exposed to two thermal environments (Ta = 22°C, RH = 35%, and Ta = 35°C, RH = 35%) in a simulated moderate workload in a climate-controlled room. The maximal aerobic capacity (VO2 max) and body fat mass of workers were determined. The heat tolerance indicators were determined based on heart rate (HR) and ear temperature (ET) before and after each experiment. A linear mixed model was employed to analyze body heat tolerance indicators using the SPSS statistical package. All physiological responses significantly increased in the warm air condition compared to the thermoneutral condition. The HR and ET increased by an average of 14 bpm and 0.75°C, respectively (p<0.05). The mixed model could accurately predict heat tolerance indicators (r = 0.95 and r = 0.97) so that the VO2 max and body fat mass were identified as the main individual influential factors. The VO2 max showed significant correlation with urinary specific gravity (r = -0.55, p<0.05), HR (r = -0.59, p<0.05), and ET (r = -0.57, p<0.05) in warm environment. The model confirmed that physical fitness is critical in increasing heat tolerance in warm environments. It can be a helpful screening tool for properly selecting workers in occupational medical examinations for working in warm air conditions. It is proposed that workers’ regular exercise and lifestyle modifications can strengthen their heat tolerance.

“…Heat is a work environment factor that is very closely related to the health of workers [6] and must be seriously addressed since it strains the body, which may lead to discomfort, heart disease and even death [7,8]. Workers in various industries, such as mining, construction, manufacturing, and agriculture, are exposed to health hazards [9].…”

“…The study also unveils the relationship between indoor temperature and heat-related health problems in the elderly. It is shown that the indoor environment could pose higher health risks than the outdoor environment [9]. Workers engaged in jobs involving operations under elevated air temperatures and humidity, or demanding physical activities, are at significant risk of experiencing heat stress [10].…”

Heat stress is a common occupational hazard workers experience in industries requiring outdoor and indoor activities. This article reviews the risk exposure occurrence of heat stress at automotive service centres for indoor and outdoor settings. The review article aims to investigate the problems and propose solutions that can be implemented to alleviate the symptoms of heat stress experienced by workers at automotive service centres that specialise in repairing tyres. The causes and symptoms of heat stress, such as dehydration, heat exhaustion, and heat stroke, are discussed at the beginning of this review. Generally, workers in automotive service centres must contend with various industrial adversities, including exposure to hot environments, machinery, and radiant heat.
