Summary: Heat-related illness is a growing concern for workers in temperate climates. This study aimed to assess the validity of wearable devices placed on different areas of the body for measuring core body temperature during repetitive physical activity in high temperature conditions. The results showed that wearable sensors are suitable for real-time monitoring of an individual's level of heat stress in high temperatures, but there was a proportional bias with these devices.

Summary: This study aimed to characterize heat stress and strain among outdoor workers in Central America and examine the association between job task, break duration, hydration practices, kidney function, and heat strain. The results showed that workers in high-temperature environments, particularly in the afternoon, experienced higher heat stress and strain, especially in the sugarcane and plantain industries. Impaired kidney function was associated with higher heart rate and core body temperature.

Summary: This study examined the occupational impacts of the 2021 Heat Dome in Canada by systematically reviewing news articles. The findings revealed diverse impacts on 52 different occupations, including work cancellations, delays, modifications, and reports of heat-related illnesses. Addressing these concerns should be a critical priority as climate projections indicate a growing trend of more hot days and intense heat waves in Canada.

Summary: This study aimed to test the hypothesis that some young healthy men would achieve short-term heat acclimation (STHA) after 5 days of a standard heat acclimation protocol. The results showed that, using the criteria of changes in core temperature and heart rate, approximately one-third of the participants achieved STHA. The whole body sweating rate remained stable during the heat acclimation process.

Summary: The study evaluated the use of the Tcore sensor to monitor rectal temperature under exercise-heat stress, finding it to be feasible and suitable for use in field conditions. The sensor showed accuracy in assessing body core temperature, providing potential benefits for athletes, soldiers, and workers performing intense physical activities under extreme hot conditions.

Summary: Yarn-based flexible sensors are crucial for wearable electronics, but their mass fabrication remains a challenge. In this study, liquid metal-based double helix core-spun yarns (DHCYs) were produced using friction core-spinning for motion monitoring, energy harvesting, and thermal management. The DHCYs exhibited excellent flexibility, breathability, washability, and durability, while the plain-woven fabric showed impressive triboelectric and temperature-responsive properties. This research shows the potential of DHCYs in smart textiles, wearable devices, and human-machine interfaces.

Summary: The study focuses on the impact of high-temperature work and limited hydration on kidney function in non-agricultural workers, specifically in salt pans. The findings highlight the need for workplace interventions to prevent heat stress and dehydration in at-risk industries. The research indicates that high-heat stress and inadequate water intake are risk factors for kidney dysfunction.

Summary: This study examined the dynamics of upper-body sweat distribution in young males wearing fully encapsulated chemical protective ensembles (FCPE) and investigated the variations in sweat rate within regions and over time. The findings demonstrated that FCPE promotes body perspiration, and the upper body can be divided into three zones based on sweat rate distribution, which is significant for designing more comfortable clothing.

Summary: The study found that different fluid supplementation methods did not significantly affect indicators such as body weight and plasma osmolality after long-duration hot exercise, but fluids supplemented with carbohydrates significantly reduced cognitive function decline. In addition, compared to exercise in a normal temperature environment, exercise in a hot environment resulted in greater dehydration and cognitive function decline.

Summary: This study found that job strain is positively associated with incident hypertension, while leisure-time physical activity is inversely associated with incident hypertension. Individuals with high job strain and low leisure-time physical activity have the highest risk for hypertension.

Summary: The study evaluated complex cognitive function, manual dexterity, and psycho-physiological parameters in outdoor tradesmen in the mining industry during summer and winter. The results showed no significant differences in cognitive function and manual dexterity between seasons, but improvements were observed over time. There were no significant differences in heart rate, core temperature, and thermal sensation between seasons, but dehydration was higher in winter compared to summer.

Summary: This study found that in tropical settings, over 70% of workers were exposed to temperatures exceeding the threshold limit value, with 11.3% experiencing a rise in core body temperature exceeding 1 degree Celsius, and 10.5% showing elevated urine specific gravity exceeding 1.020. Workers exposed to high temperatures had 2.3 times higher odds of reporting adverse health outcomes compared to unexposed workers.

Summary: This integrative literature review identified and summarized 132 studies on nurses' occupational stress between 2009-2019. Most studies were conducted in Confucian Asia and Anglo countries, with a growing number of studies in other countries. Factors were categorized into sociodemographic, work environment, and personal resources, while outcomes included health status, capability, affective and behavioral responses to work, and organizational performance, with generally consistent results. Model validation studies showed non-linear or non-direct associations between stress and outcomes.

Summary: Heat stress affects the fertility of dairy cattle, but supplementing vitamins E and coenzyme Q10 can alleviate its adverse effects on oocyte maturation and embryo development. Vitamin E was found to be more effective than vitamin C and coenzyme Q10 in improving maturation and cleavage rates, as well as increasing the count of blastocyst cells.
