Figure 4. Circadian Alignment vs. Misalignment.

Figure 4

Shown above is a schematic representation of circadian alignment between central and peripheral clocks (left panel) versus misalignment (right panel). Bright light exposure during the daytime, food intake during the daytime, and sleeping during the biological night promote circadian alignment between the central and peripheral clocks. Conversely, light exposure or food intake in the evening/at night, or sleeping during the daytime, misaligns the two clock systems and leads to metabolic dysfunction.
