“…Alterations in hydration status have been shown to affect both acute and long-term health and performance outcomes such as cardiovascular and thermoregulatory strain, cognitive and physical performance, and increased risk for developing cardiovascular, metabolic, and renal diseases [ 1 , 2 , 3 , 4 ]. Inadequate hydration becomes important in situations where access and availability of fluids are restricted (e.g., military operations and remote athletic or occupational settings) or in situations where urination is not desired [ 5 , 6 , 7 , 8 , 9 ]. Thus, commercially available beverages, including sports drinks and oral-rehydration solutions (ORS), have been developed to promote rehydration and fluid retention following activity, but may also promote fluid retention in the absence of acute fluid losses [ 10 ].…”

This study determined the beverage hydration index (BHI) and postprandial cardiac autonomic activity after consuming an isotonic beverage (IB) compared to distilled water (DW). Twenty-two participants (50% female; mean ± SD; age, 27 ± 3 year; height, 169.1 ± 12.6 cm; weight, 73.3 ± 13.8 kg; BF%, 23 ± 10%) completed two experimental trials where they consumed 1 L DW or an IB; after which urine volume and cardiac autonomic activity was measured through 240 min. Cardiac autonomic activity was quantified using heart rate (HR), log transformed heart rate variability measures (root mean square of successive R–R intervals; RMSSD; low frequency, LF; and high frequency, HF) and systolic time intervals (pre-ejection period, PEP). BHI was significantly greater after IB consumption at min 0 (MD [95% CI]; 1.31 [0.35, 2.27]), 180 min (0.09 [0.022, 0.16]), and 240 min (0.1 [0.03, 0.17]) compared to DW (p = 0.031). Net fluid balance was significantly greater in IB than DW at 180 min (90 [−16.80, 196.81]) and 240 min (106 [−13.88, 225.88]) (p = 0.037). HR decreased over time in both beverage trials but was higher following IB ingestion at 0 min (3.9 [−2.42, 10.22]), 30 min (5.3 [−0.94, 11.54]), and 60 min (2.7 [−3.42, 8.82]) (p = 0.0002). lnHF was greater 30 min post DW ingestion compared to IB (0.45 [−0.23, 1.13]) (p = 0.039). IB promotes greater fluid retention capacity compared to DW within 4 hours of consumption. The variations in cardiac autonomic measures may warrant further investigation in clinical populations (i.e., patients with autonomic failure).

“…Tidak ada formula yang baku dalam menentukan jumlah sampel yang harus diukur. Berdasarkan proffesional judgement pengukuran pajanan panas personal dilakukan pada pekerja yang beresiko, bekerja berpindah-pindah, mewakili setiap pekerjaan yang berisiko (Morrissey et al, 2021). Pengukuran dapat dilakukan dengan direct calorimetry, serta indirect calorimetry.…”

PT X merupakan perusahaan yang bergerak di bidang sanitary manufactur yang memproduksi peralatan sanitasi. Salah satu tahapan produksinya yaitu pencetakan (casting) serta pembakaran yang suhunya dapat mencapai 20000C. Penelitian ini bertujuan untuk mengethui pengendalian heat stres yang telah dilakukan perusahaan terhadap pekerja di area Kiln dan Cast shop di PT X. Penelitian ini bersifat deskriptif dengan desain penelitian cross-sectional, dengan unit analisis perusahaan manufacturing. Penelitian dilakukan dengan mengukur suhu lingkungan dan suhu yang diterima oleh pekerja yang berada di unit cast shop dan kiln. Hasil menunjukkan indeks WBGT in rata-rata area Kiln dan Cast Shop antara 30.710C-33.80C dengan pola kerja pekerja 50%-75% serta beban kerja yang masuk dalam katagori sedang jika dibandingkan dengan standard yang ditetapkan, kondisi ini dapat menyebabkan pekerja mengalami heat stress. Adapun rekomendasikan yang diberikan yaitu dengan penambahan titik untuk penyedian air minum, agar satus hidrasi pekerja tetap terjaga sehingga pekerja tidak mengalami heat stress selama bekerja PT X is a company engaged in the sanitary manufacturing sector that produces sanitary equipment. One of the production stages is molding (casting) and burning where the temperature can reach 20000C. This study aims to determine the control of heat stress that has been carried out by the company on workers in the Kiln and Cast shop area at PT X. This research is descriptive with a cross-sectional research design, with a manufacturing company as the unit of analysis. The research was conducted by measuring the ambient temperature and the temperature received by workers in the cast shop and kiln units. The results show that the average WBGT index in the Kiln and Cast Shop area is between 30.710C-33.80C with a work pattern of 50% -75% and the workload is in the moderate category when compared to the standards set, this condition can cause workers to experience heat stressed. The recommendations given are by adding points for the provision of drinking water, so that the hydration status of workers is maintained so that workers do not experience heat stress while working.

“…Workers exposed to high ambient temperatures during prolonged heavy-intensity work are predisposed to increases in core temperature (T c ) [ 1 , 2 ]. Excessive hyperthermia (T c ≥ 38 °C) reduces worker productivity [ 3 , 4 ] while increasing the risk of negative health consequences such as heat illnesses [ 5 , 6 ], workplace injury [ 7 , 8 ], and cardiovascular events [ 9 , 10 ]. According to the Bureau of Labor Statistics, there were 43 work-related deaths in the United States due to environmental heat exposure in 2022, up from 36 deaths the previous year [ 11 ], and 4910 nonfatal occupational injuries and illnesses that resulted from exposure to heat from 2021 to 2022 [ 12 ].…”

This study compared physiological responses to two work/rest cycles of a 2:1 work-to-rest ratio in a hot environment. In a randomized crossover design, fourteen participants completed 120 min of walking and rest in the heat (36.3 ± 0.6 °C, 30.2 ± 4.0% relative humidity). Work/rest cycles were (1) 40 min work/20 min rest [40/20], or (2) 20 min work/10 min rest [20/10], both completing identical work. Core temperature (Tc), skin temperature (Tsk), heart rate (HR), nude body mass, and perception of work were collected. Comparisons were made between trials at equal durations of work using three-way mixed model ANOVA. Tc plateaued in [20/10] during the second hour of work (p = 0.93), while Tc increased in [40/20] (p < 0.01). There was no difference in maximum Tc ([40/20]: 38.08 ± 0.35 °C, [20/10]: 37.99 ± 0.27 °C, p = 0.22) or end-of-work Tsk ([40/20]: 36.1 ± 0.8 °C, [20/10]: 36.0 ± 0.7 °C, p = 0.45). End-of-work HR was greater in [40/20] (145 ± 25 b·min−1) compared to [20/10] (141 ± 27 b·min−1, p = 0.04). Shorter work/rest cycles caused a plateau in Tc while longer work/rest cycles resulted in a continued increase in Tc throughout the work, indicating that either work structure could be used during shorter work tasks, while work greater than 2 h in duration may benefit from shorter work/rest cycles to mitigate hyperthermia.
