Photoplethysmographic parameters were associated with mood and fatigue in students; hypothesis-generating and should not yet change practice.
Are pulse waveform parameters indicative of mood states and chronic fatigue in healthy college students?
Pulse waveform parameters derived from photoplethysmography may serve as physiological indicators of mood states and chronic fatigue, with notable gender differences.
Park et al. (2012) studied this question.
