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. Bullough 2008-07-29T00:00:00Z http://www.jcircadianrhythms.com/content/6/1/7/comments#305607 <p>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).</p> Berndette Chasteen 2008-07-26T00:00:00Z
