Summary: Since the COVID-19 outbreak, healthcare workers wearing PPE have faced excessive heat stress due to hot weather. A field survey conducted in Guangzhou found that most HCWs experienced discomfort and profuse sweating, with a significant impact on their thermal comfort. Wearing PPE increased HCWs' thermal sensation and decreased their adaptive ability, leading to a tendency towards feeling very hot.

Summary: This study observed the thermal physiological and psychosocial responses of healthcare workers wearing personal protective equipment (PPE) at different temperatures and activity intensities. The increase in ambient temperature had a greater impact on average skin temperature, while activity intensity had a greater impact on heart rate and tympanic temperature. Healthcare workers wearing PPE experienced discomfort due to high temperature and humidity, with mask wearing and high humidity being the most frequently reported occurrences. Forehead, chest, and back were suggested as primary areas to consider for designing improvement measures for thermal comfort of PPE wearers.

Summary: This study conducted a field experiment and questionnaire survey in Guangzhou, China to investigate the thermal comfort of wearing personal protective equipment (PPE). The results showed that wearing PPE significantly increased thermal and humidity sensations, restricted airflow, and caused thermal discomfort for the subjects. The neutral operative temperature was significantly lower when wearing PPE, indicating that individuals wearing PPE preferred lower temperatures.

Summary: The objective of this study was to explore the experiences of Australian frontline healthcare workers with personal protective equipment (PPE) during the COVID-19 pandemic. The findings revealed deficiencies in PPE training, inadequate PPE availability, reuse or extended use of PPE, confusion about changing guidelines, and workplace bullying related to PPE. The lack of in-person workplace PPE training was associated with lower confidence in using PPE and a higher likelihood of workplace bullying. These issues have negative physical and psychological impacts on a female dominant workforce critical to business as usual operations and pandemic response.

Summary: This review study emphasizes the importance of personal cooling garments in thermal management, particularly during physical activity and work under hot weather conditions. It discusses the mechanisms of different types of personal cooling garments, with PCM garments being the most widely used. The study also highlights the potential of enhancing PCM effectiveness through the use of nanoparticles and biomass-derived porous carbon materials. Additionally, the review explores performance indicators and equations, evaluation methods, factors affecting cooling efficiency, and the application of PCM in textiles. Future challenges and trends in PCM garment design are also discussed.

Summary: The majority of South African informal settlements are constructed using corrugated profile galvanized metal sheets, which result in high temperature fluctuations. The study investigates the impact of plank chipboard insulation and the integration of a Phase Change Material (PCM) layer on the temperature fluctuations. The experiments reveal significant reductions in temperature fluctuations with the use of insulation and PCM, and simulations confirm the effectiveness of a lower phase change temperature range.

Summary: The COVID-19 pandemic has changed the physician-patient relationship and posed risks to healthcare workers. This study examined the personal safety of healthcare workers in public hospitals and found limited access to essential personal protective equipment (PPE) and perceived lack of support. It emphasizes the need for hospitals and public health authorities to increase access to PPE and provide support to protect healthcare workers.

Summary: This paper proposes a novel approach to cool the interior region of motorcycle helmets using nano-enhanced organic Phase Change Material. The results show that the addition of nanoparticles can significantly improve the thermal conductivity of the material, and the nano-enhanced PCM incorporated helmet can effectively reduce the interior temperature, improving the comfort for motorcycle riders.

Summary: The study found that prolonged use of personal protective equipment (PPE) can lead to various adverse skin reactions among healthcare workers, particularly in different facial locations such as the bridge of the nose and ears. Improvement in guidelines for PPE usage to protect skin health is recommended, along with modifications to PPE designs to accommodate different face shapes and select appropriate materials to enhance device safety.

Summary: During the COVID-19 pandemic, 66.22% of healthcare workers reported new-onset headaches associated with personal protective equipment. These equipment-related headaches were associated with female sex, a history of COVID-19 disease, and the presence of primary headaches diagnosed before the pandemic.

Summary: In the hot summer of 2021, most frontline healthcare workers conducted residents' nucleic acid tests outdoors instead of taking care of COVID-19 patients in hospitals. Wearing personal protective equipment (PPE) caused thermal discomfort, and an investigation into its prevalence and characteristics was conducted. The results showed that wearing PPE increased the levels of thermal discomfort and humid discomfort, with feelings of being very hot and uncomfortably humid being the most influenced. Thermal discomfort was common and associated with factors such as environmental temperature, work setting, age, and previous pandemic experiences.
