Figure 5:

Double plotted 24-h average activity (arbitrary units) and light exposure (lux) measured in 60-s epochs using actigraphy devices. Means of each epoch for 5 days of recordings are presented. Men (grey) begin their activity earlier than women (black) and display higher amount of activity during the most active ten-hour period (M10) (A). Light exposure during the first three hours after sunrise was higher for men in comparison to women, and total light exposure during consecutive 16 hours (M16lu) also was higher for men in comparison to women (B).
