Electroencephalography associated with thermal discomfort induced by temperature upward ramping

Abstract

This study investigates the brainwaves associated with thermal discomfort induced by temperature upward ramping. This experiment was conducted on 35 university students. Participants stayed for 40 minutes in a climate chamber where the temperature gradually increased, and at the same time, EEG measurements and thermal comfort answers were performed. As a result of the temperature increasing, the participants felt uncomfortable and the relative power value of all frequency bands gradually increased. As a result of correlation analysis of individual thermal comfort change and relative power change, the alpha power at Cz, C3, the beta power at Fz, Cz, and C4 and the gamma power at C4 increased.
