   Does light exposure cause fatigue?

   • To minimize the potential confounding of fatigue on subjective feelings, the present study adopted a short-term light exposure. However, compared to short-term exposure, long-term exposure to light might have a different or even a reverse effect on cerebral activity.

   Does light exposure affect subjective affect and comfort?

   • The tasks performed during light exposure and associated (potential) fatigue might also confound the effects of light on subjective affect and comfort 26. Previous studies had confirmed the effectiveness of short-term light exposure on modulating physical and psychological processes 8, 13, 27, 28.

   Does light exposure cause alertness?

   • The results showed that both short-wavelength dominant light exposure and higher intensity white light exposure induced alertness. However, those influences depended on factors like the participants’ homeostatic sleep drive and the time of day the participants received the light exposure.

   Does light exposure affect alertness and cognitive functions?

   • Figure 4 depicted the trend of IIL literature focusing on alertness and higher cognitive functions. In total, we have identified 30 studies investigating the influence of short wavelength dominant light exposure and 26 studies investigating the influence of the higher intensity white light on alertness and higher cognitive functions.

   Does light exposure affect subjective alertness?

   • Among the studies investigating the influence of high MDER light exposure on subjective alertness, 50% (6 out of 12) reported a beneficial influence of light exposure with MDER ranging between (0.70–1.4). For objective alertness, 41.7% of the studies (5 out of 12) reported beneficial influences of light exposure with MDER ranging between (0.4–1.4).
