Abstract (EN):
Even in sedentary activities, the workload is justifying more accurate
studies about its impact on human beings mainly when related to
different temperature and humidity conditions. One of these impacts is
related to mental activity, which can be studied by the amplitude of
Alpha and Beta waves. This study aims to evaluate brain activity in the
occipital lobe from the amplitude of the EEG signal (Alpha and Beta
waves) and to relate it to different conditions of temperature and
relative humidity (RH) in sedentary tasks. Tests were performed under
four different conditions (22°C-40%RH, 22°C-80%RH, 32°C-40%RH
and 32°C, 80%RH) with 30 volunteers from which 15 were validated.
Results suggest that both temperature and humidity influence the
amplitude of the EEG signal (Alpha and Beta waves) in both
hemispheres. The greatest amplitudes were found whenever
environmental temperature and/or relative humidity values were
higher. The results are in agreement with other authors.
