摘要

Hyperthermal environments can harm workers' health and safety. However, it is difficult to include effective protection into standards because heat-related impacts vary significantly accord-ing to individual workers and multiple factors. Studies suggested obvious relationship between en-vironment condition and bio-electricity signal, including electroencephalogram (EEG) signal. We used a detector with 64 electrodes to perform dedicated EEG measurements of nine individual sub-jects to analyze human cerebral activity under hyperthermal (35℃, 80％ RH) and standard condi-tions (25℃, 30％ RH). Amplitude changes of the frequency wavebands were analyzed using statist-ical analysis. Seven participants showed increasing beta activity due to high temperature and high humidity in the primary somatosensory cortex (electrode C3) and the temporopolar region (elec-trode FT 8). The amplitude value of alpha wave is increased from 0.194 to 0.213 while the amp-litude value of beta wave is increased from 0.144 to 0.160. Value is decreased due to hyperthermal environment for most people. The results of this study could be used to inform the development of wearable equipment to monitor the health of on-site workers, which is fundamental to improve worker safety and wellbeing.
