Circadian Math: One plus One Doesn’t Always Equal Two
|
 Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system—the biological cycle that repeats approximately every 24 hours—requires daily light exposure through the eye’s retina to remain synchronized with the solar day.
In a new study published in the June issue of Neuroscience Letters, LRC researchers demonstrated that when it comes to the circadian system, not all light exposure is created equal. The findings have profound implications for exploring how lighting can be used to adjust our bodies’ clocks, and they could redefine the way lighting is manufactured, according to Mariana Figueiro, lead author of the paper and LRC assistant professor.
