Figure 4.
Individual resetting responses to the very dim light (0%), intermittent bright light (23%) and continuous bright light (100%) exposure conditions, measured with core body temperature minimum (CBTmin) and melatonin phase markers: DLMOn25% (dim light melatonin onset), MP25% (midpoint), and DLMOff25% (dim light melatonin offset). Phase-advance shifts are plotted as positive values, whereas phase-delay shifts are plotted as negative values. Horizontal bars represent the median phase shift observed in each condition.
