TL;DR: The overall result suggests that participants were most and least fatigued when viewing text illuminated by high color-rending and greenish white backlighting, respectively, suggesting that fatigue can be reduced using LEDs with different spectral distributions.

TL;DR: It is found that respiratory frequency fluctuations in HR are parasympathetically mediated and that blood pressure fluctuations at this frequency result almost entirely from the direct effect of centrally mediated HR fluctuations, and the sympathetic nervous system appears to be too sluggish to mediate respiratory frequency variations.

Sensitivity and accuracy of the visual analogue scale: a psycho- physical classroom experiment.
TL;DR: It was concluded that this was due to a shift in either perception, cognition or scoring between the two sessions, and it was recommended that authors using the visual analogue scale have valid reason in their own setting for using a transformation and present the distribution, or at least the medians and ranges of their raw scores.

TL;DR: Sympathetic hyperactivity based on decreased parasympathetic activity is associated with mental fatigue induced by prolonged cognitive load, and the HF was lower and LF/HF ratio was higher as compared to those after the relaxation session.

Effect of illuminance and color temperature on lowering of physiological activity.
TL;DR: Low color temperature light creates a smooth lowering of central nervous system activity, and that low color temperature illumination can be used effectively in a bedroom or other such environment where it is desirable to facilitate lowered physiological activity is suggested.
