“…Some limitations of the current Kenzen T C model include minimal clothing layers for most of the studies and a relatively younger subject population. Many of the worksites include older individuals (e.g., >50 y) and workers often wear 2–3 layers of clothing [ 3 , 4 , 5 , 6 , 9 , 27 ]. Thus, future research should validate the Kenzen T C algorithm in older adults and individuals wearing heavy clothing layers while working in the heat.…”

“…As climate change is not only increasing average temperatures globally, but also the frequency of extreme heat events [ 1 ], an increasing number of workers (e.g., military, construction, agriculture, etc.) will be exposed to these hotter temperatures on a more frequent basis [ 2 , 3 , 4 , 5 , 6 , 7 ]. Workers experience a 2% loss in productivity for each 1 °C increase in wet bulb globe temperature (WBGT) ≥ 24 °C [ 6 ], and in addition to productivity losses, the number of heat-related injuries and illnesses at job sites is on the rise.…”

Workers experience a 2% loss in productivity for each 1 °C increase in wet bulb globe temperature (WBGT) ≥ 24 °C [ 6 ], and in addition to productivity losses, the number of heat-related injuries and illnesses at job sites is on the rise. For example, in construction settings, the risk of heat-related deaths has increased since the 1990s, and is predicted to continue to increase unless heat-mitigation strategies are adopted at these sites [ 7 ].…”

“…One such heat-mitigation strategy is to monitor core temperature (T C ) and alert workers when they reach temperature thresholds that predispose workers to heat-related injuries and illnesses (i.e., 38.2–38.5 °C; [ 8 ]). While these T C thresholds are ~1 °C lower than the T C at which heat injuries and illnesses typically surface, research shows that if workers stop and rest to hydrate and cool down at these lower T C thresholds, they will be able to work for prolonged periods of time in the heat without ever reaching these detrimental T C [ 6 , 8 , 9 ]. However, accurately monitoring individuals’ T C on a daily basis at the job site is prohibitively invasive (i.e., rectal and esophageal probes) or expensive (i.e., gastrointestinal pill).…”

With climate change increasing global temperatures, more workers are exposed to hotter ambient temperatures that exacerbate risk for heat injury and illness. Continuously monitoring core body temperature (TC) can help workers avoid reaching unsafe TC. However, continuous TC measurements are currently cost-prohibitive or invasive for daily use. Here, we show that Kenzen’s wearable device can accurately predict TC compared to gold standard TC measurements (rectal probe or gastrointestinal pill). Data from four different studies (n = 52 trials; 27 unique subjects; >4000 min data) were used to develop and validate Kenzen’s machine learning TC algorithm, which uses subject’s real-time physiological data combined with baseline anthropometric data. We show Kenzen’s TC algorithm meets pre-established accuracy criteria compared to gold standard TC: mean absolute error = 0.25 °C, root mean squared error = 0.30 °C, Pearson r correlation = 0.94, standard error of the measurement = 0.18 °C, and mean bias = 0.07 °C. Overall, the Kenzen TC algorithm is accurate for a wide range of TC, environmental temperatures (13–43 °C), light to vigorous heart rate zones, and both biological sexes. To our knowledge, this is the first study demonstrating a wearable device can accurately predict TC in real-time, thus offering workers protection from heat injuries and illnesses.

BackgroundTo limit exposures to occupational heat stress, leading occupational health and safety organizations recommend work–rest regimens to prevent core temperature from exceeding 38°C or increasing by ≥1°C. This scoping review aims to map existing knowledge of the effects of work–rest regimens in hot environments and to propose recommendations for future research based on identified gaps.MethodsWe performed a search of 10 databases to retrieve studies focused on work–rest regimens under hot conditions.ResultsForty‐nine articles were included, of which 35 were experimental studies. Most studies were conducted in laboratory settings, in North America (71%), on healthy young adults, with 94% of the 642 participants being males. Most studies (66%) employed a protocol duration ≤240 min (222 ± 162 min, range: 37–660) and the time‐weighted average wet‐bulb globe temperature was 27 ± 4°C (range: 18–34). The work–rest regimens implemented were those proposed by the American Conference of Governmental and Industrial Hygiene (20%), National Institute of Occupational Safety and Health (11%), or the Australian Army (3%). The remaining studies (66%) did not mention how the work–rest regimens were derived. Most studies (89%) focused on physical tasks only. Most studies (94%) reported core temperature, whereas only 22% reported physical and/or mental performance outcomes, respectively. Of the 35 experimental studies included, 77% indicated that core temperature exceeded 38°C.ConclusionsAlthough work–rest regimens are widely used, few studies have investigated their physiological effectiveness. These studies were mainly short in duration, involved mostly healthy young males, and rarely considered the effect of work–rest regimens beyond heat strain during physical exertion.
