Figure 1. Actigraphy measures of light exposure, total activity, and sleep time between workers in workplaces with windows (N = 11) and without windows (N = 10).

Actigraphy data collected in a subset of the office workers show that those with windows in the workplace had higher light exposure (A), more total activity (B), and longer sleep time (C) than workers without windows in the workplace. * p < 0.05, ^† p < 0.10.
