Evaluation of a Wearable Non-Invasive Thermometer for Monitoring Ear Canal Temperature during Physically Demanding (Outdoor) Work.

Aimed at preventing heat strain, health problems, and absenteeism among workers with physically demanding occupations, a continuous, accurate, non-invasive measuring system may help such workers monitor their body (core) temperature. The aim of this study is to evaluate the accuracy and explore the usability of the wearable non-invasive Cosinuss° °Temp thermometer. Ear canal temperature was monitored in 49 workers in real-life working conditions. After individual correction, the results of the laboratory and field study revealed high correlations compared to ear canal infrared thermometry for hospital use. After performance of the real-life working tasks, this correlation was found to be moderate. It was also observed that the ambient environmental outdoor conditions and personal protective clothing influenced the accuracy and resulted in unrealistic ear canal temperature outliers. It was found that the Cosinuss° °Temp thermometer did not result in significant interference during work. Therefore, it was concluded that, without a correction factor, the Cosinuss° °Temp thermometer is inaccurate. Nevertheless, with a correction factor, the reliability of this wearable ear canal thermometer was confirmed at rest, but not in outdoor working conditions or while wearing a helmet or hearing protection equipment.

Physiotherapy students' perceived stress, stressors, and reactions to stressors: A comparative study between Sweden and The Netherlands.

BACKGROUND AND PURPOSE: Studies of healthcare students report increased levels of stress, with academic pressures being the greatest source. The objective of this study was to examine the differences in the overall stress level, stressors, and reactions to stressors between physiotherapy students at the University of Gothenburg (GU) and those at the Hanze University of Applied Sciences (HUAS). METHODS: The Student-life Stress Inventory was used. The participants (n = 116) included physiotherapy students at GU and HUAS. The distribution of the questionnaire occurred during a regular lecture or in a lecture that was scheduled particularly for its distribution. RESULTS: At GU, 13.7% of the students rated their level of stress as mild, whereas 72.5% of them rated it as moderate. The corresponding values for HUAS students were 43.9% and 43.9%, respectively. This difference between two universities was significant (p = 0.006). The total score of the subcategories indicated that the students at GU reported significantly higher levels of stressors (p = 0.027) and reactions to stressors (p = 0.003). However, there were no significant differences in the male participants between the universities. CONCLUSION: Female students in their three-year educational program in Sweden experienced significantly more stress than Dutch female students in their four-year educational program.
