See for example the bottom panel of <b>Figure 1</b> from a related paper <b><a href='http://www.ncbi.nlm.nih.gov/pubmed/16901343'>(Figueiro <i>et al.</i> 2006)</a></b> where the Daysimeter was used.</p> J.

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).</p> Berndette Chasteen 2008-07-26T00:03:46Z http://www.jcircadianrhythms.com/content/6/1/7 Rea et al.
