It is standard protocol that participants should wear the device if they get up during
normal sleep hours (e.g., to use the bathroom) so such light exposures would be measured.
See for example the bottom panel of Figure 1 from a related paper (Figueiro et al. 2006) where the Daysimeter was used.

This new technique for studying the effects of circadian disruption is a wonderful
step forward for our understanding of this important area of human health. I just
worry that having the Daysimeter device left next to the subject during sleep hours
will miss critical nighttime light exposure when the subject gets up in the night
(e.g. turning on a bathroom light or passing a window which admits streetlight).
