But it may also open the 
door to the blues. Because a new study reveals that <A

signs of clinical <A href="http://www.scientificamerican.com/topic.cfm?id=depression">depression</A>.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.scientificamerican.com/podcast/episode.cfm?id=light-all-night-not-alright-09-10-21"> our bodies use cues about lightness and dark to regulate our hormones and of 
course our <A href="http://www.scientificamerican.com/topic.cfm?id=sleep">sleep</A> cycles. So what might these 
extra photons be doing to our health?</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.scientificamerican.com/podcast/episode.cfm?id=light-all-night-not-alright-09-10-21"> scientists housed mice in a room where the lights were always on. After three 
weeks, they found that mice who lived in the spotlight showed symptoms of 
depression, more so than mice who enjoyed eight hours of darkness at night. 
Interestingly, mice who could escape the light by ducking into a dark tube also 
escaped the worst of the depression</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.scientificamerican.com/podcast/episode.cfm?id=light-all-night-not-alright-09-10-21"><P>So flip that light switch at your own risk.
